Validation Question with Indexed Properties

  If I understand your questions correctly, you can define two String 
  arrays
  in your form bean, one for allRoles, and the other for 
  selectedRoles, which 
  is the array of roles of the current user. Before forwarding 
  to your jsp, 
  in your action class, you can retrive all the roles of the 
  currently user, 
  and set the roles to the selectedRoles in the form bean.

 Hello All,
  
 I am running into this problem, that I am not able figure 
  out how to 
  do
  it
 properly.  I have searched the web and have not found a 
  decent example.
 What I am trying to do is use html:multibox taglib to 
  display a set of
 checkboxes.  These check boxes represent the user's security 
  preferences.
 So if the user has a particular security token, then the 
  respective 
  check
 box should be checked.
  
 In order for this to work properly, I have to get two 
  things, all the
 security tokens that exits in the system.  And I  have to get the
  security
 tokens that the user already has.  In my ActionForm, I 
  have two methods:
 one that gets all the security tokens in the system and 
  second that gets
 only the tokens that the user has.   The following is 
  what I am using in 
  my
 jsp to display checkboxes.
  
 logic:iterate name=associateUserRoleForm property=allRoles
 id=element
   html:multibox property=selectedRoles
bean:write name=element /
   /html:multibox
   bean:write name=element /
   br /
 /logic:iterate
  
  
 Right now I am able to get allRoles successfully, but in order to
  retrieve
 the selectedRoles, I need a way such that my ActionForm
 (associateUserRoleForm) can get hold of this user or this 
  user's id, 
  which
 is already in the session.  Once I get this I can then 
  display all the
 security tokens and check those tokens that the user already has.
  
 How can I do this?  Am I on the right track or is there a 
  better way 
  to
  do
 this?
  
 Thank You very much for your help!

RE: Multibox and selected values

[Craig Tataryn]

Oh right, sorry yeah my code looks in the Application scope in this instance.  

For getting the request scope variables I needed I had subclassed DispatchAction for 
my project and
set the properties on my form bean which were grabbed from the request from within an 
overriden
dispatchMethod (execute if subclassing normal Action) method.  I suppose you could do 
the same as
well and add a get/set UserSession property on your a subclassed ActionForm.  Not sure 
how great an
option that is?

Here's what my code looked like:

protected ActionForward dispatchMethod(
ActionMapping mappings,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response,
String methodToCall)
throws Exception {

if (form instanceof ApptiusForm) {
//here's where I grab some user session variables and present them to my form bean

((ApptiusForm)form).setSessionUserName((String)request.getSession().getAttribute(POActionServlet.USER_KEY));

((ApptiusForm)form).setSessionUserId((String)request.getSession().getAttribute(POActionServlet.USERID_KEY));
}

String dispatchTo = ApptiusUtils.isNull(methodToCall,initialize);
ActionForward forward = null;

try {
forward = super.dispatchMethod(mappings, form, request, response, do 
+
ApptiusUtils.UCaseFirst(dispatchTo));
} catch (Exception e){
ApptiusLog.logError(e, this.getClass().getName() + :: + do +
ApptiusUtils.UCaseFirst(methodToCall) +  does not exist, or an error occured within 
that function,
check stack trace below);
throw e;
}

if (forward == null) {
return mappings.findForward(dispatchTo);
} else {
return forward;
}
}

Hi there, is there a configuration setting for Struts which tells it to set a property 
on a form
bean of type Integer (not int) to null instead of new Integer(0) when the 
corresponding value
coming in from the user's form is an empty string?

I had to create a plugin that had the following in it's init() method:

ConvertUtils.register(new IntegerConverter(null),Integer.class);

Thanks,

Re: does not mean 0 [in my app] :)

[Craig Tataryn]

Well, it really has nothing to do with the type of tag I am using be it 
radio,checkbox,text; I just
wanted to know if there is a declarative way to override the default values used by 
BeanUtils in
Struts.  Or is putting the code (from my previous message) in a plug-in the best 
practice?

In my mind, I can see why you would need to default an int property value to 0 when a 
value is not
specified (they have no choice, it has to be set to something), but why they would 
take this liberty
with an Integer object (or any other decendant Number), i'm not quite sure.

RE: help me about indexed properties

[Craig Tataryn]

Hi Mike, the attributes for logic iterate are all explained here:
http://jakarta.apache.org/struts/userGuide/struts-logic.html#iterate
and
http://jakarta.apache.org/struts/faqs/indexedprops.html

I've put it in my own words for you below:

For logic:iterate
==
name attribute: tag looks in all three scopes (page,request,application)for a bean 
with the name
equal to the value of this attribute.  If it is found, and there is no property 
attribute
specified elsewhere in the tag, then it will use the bean from the name attribute as 
the List/Map to
iterate over.

property attribute: The property specified in the property attribute will be applied 
against the
bean found in the name attribute and the value of this property will be used as the 
List/Map to
iterate.  So if you specify name=MyForm and property=addresses then the list which 
will be
iterated over will be the value passed back from the interate tag evaluating 
MyForm.getAddresses()

id attribute: for each loop of the iterate tag, place the next element from the list 
into a
page-level bean named by the value of the id attribute.

idIndex attribute: for each loop of the iterate tag, place the current index value of 
the element
from our List in the page-level int variable named by the value of the idIndex 
attribute (value is
in [0..list.length])

For html:text
===
The attributes are pretty well explained in
http://jakarta.apache.org/struts/userGuide/struts-html.html#text

Hope that's enough to get you started.

 is not really required if we are really follow MVC pattern as we are not
 putting too much of logic in it...BUT just wanted to know that is there

Re: map-backed action forms - form params not loaded ?

[Craig Tataryn]

Yeah, definitely show us what your jsp looks like for your property attribute.  If you 
are doing it
like Daniel, everything should be good.  If you are doing something like this:

html:text property=value(test1).someProperty/

then it won't work when you submit your form unless that HashMap you have in your 
FormBean is
initialized with an object keyed by test1 and has a property named someProperty.  
You might do
something like:

public Object getValue(String key) {
   if (!this.params.containsKey(key)) {
  this.params.put(key,new SomeObjectThatHasA_someProperty_Getter_Setter());
   }
   return params.get(key);
}

 function set(target) {document.forms[0].dispatch.value=target;}
 
 /script
 
 table border=1 width=100%
 
 
 
 tr
 
 th
 
 html:submit onclick=set('delete');Delete/html:submit 
 
 ..
 
  
 
 so basically i want a pop up when user clicks the above Delete button
 (struts uses html:submit  to generate a HTML button) and when i click
 on the yes on this pop up, i want the set(target) to get set
 
 Thanks in advance for help,
 
 Sam.

Re: Cannot Create Iterator

[Craig Tataryn]

Try this:
logic:iterate id=map name=alpha property=values
 logic:iterate id=submap name=map property=value

When you iterate a map, the elements are of type Map.Entry
(http://java.sun.com/j2se/1.4.2/docs/api/java/util/Map.Entry.html)

See: http://jakarta.apache.org/struts/userGuide/struts-logic.html#iterate for more 
details.

 Hi,
 
 I have a bean in session scope wich is a HashMap of HashMap, i.e., the key's
 value stored is another HashMap.
 
 Ex.:
 
 HashMap alpha = new HashMap();
 alpha.put(key1,new HashMap());
 
 request.getSession().setAttribute(alpha,alpha);
 
 But, when I use :
 logic:iterate id=map name=alpha 
 logic:iterate id=submap name=map 
 it produces an JSPException: Cannot create iterator for this collection
 
 Is that any known bug? How to correct this issue?

Re: Can i do 2 submit at a time

[Craig Tataryn]

Hi Sougata, you can if you set the target attribute of the forms either 
programmaically or in the
tag itself to a frame other than the current one.

Something like:
html:form ... target=form1FrameResults
.
.
.
/html:form

html:form action=/myAction target=myActionResults
.
.
.
/html:form

html:form action=/myOtherAction target=myOtherActionResults
.
.
.
/html:form

input type=button value=Submit Both Forms
onclick=myActionForm.submit();myOtherActionForm.submit();

And you would need two frames from a frameset named myActionResults and 
myOtherActionResults, or two
iFrames if you're clients are using IE v4.0, Mozilla, Netscape v6.0 or Opera.  Or 
you could
probably get away with using the current frame as a target for one of the forms.

Craig.

Re: Problem with Map-backed ActionForm and Key value

Heh, Brian you were having the same problem I was.  I posted yesterday with subject:

JSP.2.13.1 Request

 The reason I have a scriplet in there is because I have a dynamic form and 
 the value of the key changes all the time. I want the value of the key to be 
 the id of the user logged in.
 
 However, this is giving me problems because the value of the key is being 
 taken literally as %=value.getUserId()% rather than the value of the 
 userId. The scriplet %= value.getUserId % is correct because I have tested 
 it with System.out.println(value.getUserId). So it looks like I cannot put 
 my scriplet in there. Has anyone experienced this before? Or does anyone 
 know why it won't et me do this? Any way to get around this?
 
 I'd appreciate any help. I've been stuck on it for two days now.

[RT Expr] for html:text property

[Craig Tataryn]

Hi, this might be a Tomcat vs. ServletExec thing, but I was trying the following 
under Tomcat and
got an error message to the effect of Null property value for 'address()':

html:form action=/TestIndexed
logic:iterate name=TestIndexedForm property=regions id=region
h1%=region%/h1
html:text name=TestIndexedForm 
property=address(%=region%).street/
html:text name=TestIndexedForm 
property=address(%=region%).city/
/logic:iterate
/html:form

If I rewrite my html:text property as below, all is good in the world:

html:text name=TestIndexedForm property='%=address( + region + ).street%'/
html:text name=TestIndexedForm property='%=address( + region + ).city%'/

Just wanted to know why the first way wouldn't work?

 According to the JSP 1.1 and 1.2 Specifications, it is illegal to have *part* of

Re: .NET: We are just like Struts... only better.

[Craig Tataryn]

It's kind of a catch .22, I use struts on projects that make money for me.  
If someone started taking my projects and replicating them for free, I would 
probably have a problem with it :)  Although in this case, MS did not have a 
Struts to begin with.  ASP.net is sweet, but only because the development 
environent makes it sweet.  If we can get the same RAD functionality out of 
Eclipse w/ JSF and perhaps Flex, then we'll really be cooking.

Although Struts is a wonderful thing, I still look at web development with 
J2EE as a bit of a tedious thing.  Well, actually now that I have a pretty 
robust taglib built, not so tedious, but still, I'm not dragging and 
dropping html form controls (or struts-html.tld taglib controls) to a 
designer screen, linking code and compiling.  I have to do it all by hand :( 
 Let's hope Eclipse VE adopts a JSF designer!

Our War Money Chest is bigger than all of you all the Java guys (including 
the Open Source).

[EMAIL PROTECTED] how can M$ have that money?

So, this mean we all must wake up, :) to make our product more user 
friendly, and make everyone can learn it, update it, and make it perfect.

ASP.net is a product based, Struts is a spiritual lovely project. They 
cannot compare it.

But if ASP.net can be compare with MVC not with Struts. :) sad to hear that 
if we port Struts to .NET, Microsoft wont support it, because they said, we 
include it in ASP.net already.

What do you think?

Thats good.

Btw: If I were you I would set the Netscape bar to version 7 (or any 
mozilla
version above 1). Netscrap 6 is based on a pre-1 version of Mozilla, and 
has
a couple of very nasty bugs that can make  trying to do certain DHTML 
things
an absolute nightmare. (Such as not submitting values for controls that are
under hidden nodes, etc...)

The other thing to keep in mind is that JavaScript widgets always seem to
take far longer to implement than you think they will! - So the simpler you
can keep things the better, and as with all languages using good 
programming
techniques in JavaScript will pay off when it comes to maintenance and
enhancement. Its very easy when coding JavaScript DHML stuff to just anyhow
try and bang together something that runs but where the code is very ugly.
Ive learnt the hard way that it quickly becomes a nightmare to maintain!
(and yet I keep doing it. garrgh! (99.9% of the freely downloadable JS
widgets to be found on the net on various DHTML sites are nasty like this.
Its often actually easier to roll your own than to try and find a suitable
widget out there and modify it for your needs (tree components being a 
prime
example))

So even if its just a simple widget like the two box selector thinghy,
sitting down to design it properly , and make it modular and reusable (for
example writing a custom tag to encapsulate it in a way that seems
transparent to the page designer), will pay dividends!
If your not totally familiar with the subtle details of JavaScript (how
objects work, prototyping, implicit type casting etc...), spending a day
studying the language in detail (ie: actually making notes like you did 
back
in college) will be a day well spent! (it will save you at least a week
debugging!)

 Still, if you are in a position to limit your audience (such as with
 intranet apps) to just the more common modern browsers (IE5+,
 Mozilla) there is indeed a lot you can do with DHTML.
I should have said that up front-- it is intranet and we can (and do)
refuse to support browsers which won't play nicely.  All I officially
have to support is a reasonably recent IE  Netscape.  And they can't
disable javascript, or they won't get very far. :)  I don't go out of my
way to break stuff on other browsers (and I test from home on
Mozilla/Konqueror) but if it gets to be too much trouble, I don't have
to mess with it.
Thanks for the tips!

Netscape 4.7x and IE.  Nightmare is one way of putting it :)  Thank god for 
DHTMLLib from siteexperts.com and the Microsoft Script Debugger/Visual 
Interdev.

And also, yeah, not everyone is strong in Javascript so the next person who 
comes down the road ends up creating more problems than the one they are 
debugging!

I think Flash will really take off once us developers start using it as the

I don't think understanding it is the key here ... I think maintenance of 
it, specifically maintenance by other developers besides the original 
developer, becomes a bit of a nightmare, and that's my definition of 'ugly' 
... :) Dynamically rewriting the HTML on a page does really get ugly ... 
the facilities to do it are there, but they aren't very nice, IMHO ... 
especially when you start needing to support the ideosyncracies of IE v. 
Moz ... which still exist, unfortunately. IE's DOM support isn't as 
full-fledged as what Moz has, and IE supports certain proprietary things, 
still, that Moz does not.

RE: [Tiles] tiles controller not processing tiles request

[Craig Tataryn]

Thanks David, I did end up figuring it out, thanks for the tip about the 
controller, I noticed in the plugin source that it would instantiate it if 
it was not already present.

I should add that when I posted my solution, I had the wrong class used on 
my action, it should read:

   action
path=/Welcome
type=org.apache.struts.actions.ForwardAction
parameter=mainLayout.welcome/
I think I originally said I used ActionForward, not ForwardAction.

 Hey guys, I have the following in my struts-config.xml:

 My tiles-defs.xml file looks like this:

 Now, when I goto http://localhost:8080/mywebapp/ the

 invoked which is supposed to forward to the
 mainLayout.welcome definition.
   However Tomcat comes back with a HTTP Status 404 -
 /aclpo/mainLayout.welcome - The requested resource

 Any ideas what might be happening?

RE: URGENT - Help defending Struts

[Craig Tataryn]

Canadian Firearms Registry system. 
(https://secure.ecom.cfc-ccaf.gc.ca/eCFRSInternet/openLicenceEntry.do?language=English)

It must be scalable because I waited until close to the deadline for 
registering my firearms and it was responsive (last year all non-restricted 
firearms in Canada (i.e. hunting rifles) were required to be registered by 
Jan 1 2001).

This question comes up periodically, so I started a list of Struts-powered 
sites.

http://simonpeter.com/techie/java/struts/sites.html

I hope this helps.

I know that I wouldn't like to think about not using it on the Intranet 
application that I head up the development team for. It has greatly aided 
our productivity and has now come through it's second peak season with 
flying colours. We started with Struts 1.0 and with a little help from 
Chuck Cavaness we were early adopters of 1.1. :-)

All:



Our CIO is currently fighting the use of Struts by saying that
it is not
widely used in B2C sites.  Does anyone know of any sites, preferably
commerce sites that are using Struts?  This would be extremely helpful.



The issue is that the CIO is looking for sites that may be similar to
ours that are using Struts already.



Thanks very much,

RE: OT: Examples of HTML-based user interfaces?

[Craig Tataryn]

We implemented that very widget you describe in javascript and wrapped a 
taglib around it at my previous job.  I don't have access to the code, but 
I'm sure I could whip up something similar to it.  It was all client side 
w.r.t. when you clicked the add/remove/up/down arrows.  If I remember 
correctly, the tricky part was when you click the submit button, you had 
to programmatically (in javascript) select all the items in the right hand 
list so they would be submitted along with the form data.

I've wrapped a few of this guy's javascript widgets (specifically the 
xTree/xLoadTree and the TableSort) and added extra features:

http://webfx.eae.net/

Top knotch widgets from that site!

Craig W. Tataryn




Does anyone have examples of some fancy things to do with HTML-based
user interfaces? For example, I've currently got a request to show two
boxes of items with add/remove arrows. So selecting in the left-hand
box and clicking the arrow will move the item to the right hand box.
I'm sure it's possible with CSS, JavaScript and hidden form fields.
(I'm pretty sure they got the idea from adding recipients to an email in
Outlook.)
I also have a long-standing requirement to dynamically grow a field,
when the user types something in a text box and clicks a button, that
item moves up and a new, blank field appears. I'm currently doing
this with an add button, which submits the form to the Struts app, the
entry gets added to a session scope bean, then back to the form with
read-only displays of the stuff in the bean and [the same] blank field.
(Although it looks like a new line, it isn't, it's the same form
field.)
Googling turns up a bunch of essays on what makes a good user interface,
but not too much on tips and tricks.

RE: [Tiles] tiles controller not processing tiles request

[Craig Tataryn]

Figured this one out.  Basically if you use tiles within your global 
forwards you are SOL, the tiles request processor only gets invoked for 
struts actions (i.e. *.do).  This can probably be solved by specifying a 
subclass of ActionForward which is tiles aware for the className attribute 
of your global forward.  I didn't see any such tiles aware forward class in 
the 1.1 dist, so I just worked around it like so:

Change my global forward for welcome from:

global-forwards
 forward name=welcome path=mainLayout.welcome/
/global-forwards
To:

global-forwards
 forward name=welcome path=Welcome.do?dispatchAction=initialize/
/global-forwards
.
.
.
action-mappings
 action
   path=/Welcome
   type=com.mypackage.controller.WelcomeAction
   parameter=dispatchAction
 forward name=initialize path=mainLayout.welcome/
   /action
/action-mappings

Hey guys, I have the following in my struts-config.xml:

 /definition
/tiles-definitions
Now, when I goto http://localhost:8080/mywebapp/ the welcome forward 
is invoked which is supposed to forward to the mainLayout.welcome 
definition.  However Tomcat comes back with a HTTP Status 404 - 
/aclpo/mainLayout.welcome - The requested resource

Any ideas what might be happening?

tiles-definitions

 definition name=mainLayout path=/html/mainLayout.jsp
   put name=header value=/html/header.jsp /
   put name=left   value= /
   put name=main   value= /
   put name=footer value=/html/footer.jsp /
 /definition
 definition name=mainLayout.welcome extends=mainLayout
   put name=body value=Welcome.do?dispatchAction=initialize/
 /definition
/tiles-definitions
Now, when I goto http://localhost:8080/mywebapp/ the welcome forward is 
invoked which is supposed to forward to the mainLayout.welcome 
definition.  However Tomcat comes back with a HTTP Status 404 - 
/aclpo/mainLayout.welcome - The requested resource 
(/mywebapp/mainLayout.welcome) is not available

Any ideas what might be happening?

Thanks,

Re: Tiles and parameters...

[Craig Tataryn]

Whacky whacky stuff.  Are you completely sure that ListUsersAction isn't
doing a request.setAttribute for the order and sort parameters it recieves?
Is this display taglib custom?   I don't see you passing it the order and
sort parameters through it's attributes, meaning that it is getting them
from some other source (session)?  Perhaps ListUserAction is somehow priming
the display:table tag...

Craig.

 Craig,

 Yes, I am relatively new to Tiles. This is my first major project using it
 and we make extensive use of Tiles in our webapp. We also use the
display
 taglib and take advantage of its column sorting support. Sorting of table
 data is handled automatically by this taglib using request parameters and
it
 works fine in our webapp. For example, the default display of our user
list
 is sorted in ascending order based on the values in the 4th column (zero
 based sort offset in example below) of the listing like so:

   /portal/admin/users/list.dbm?order=ascsort=3

 This will trigger the following action mapping in our struts-config.xml
 file:

   actionpath=/portal/admin/users/list
  type=com.verisign.dbms.portal.ListUsersAction
 forward name=success path=portal.admin.users.list/
   /action

 And the following tile definitions are interpreted when the success
 forward is used:

   definition name=portal.admin.users.list extends=portal.admin.users

 put name=menu   value=portal.menu.admin.users.modify /
 put name=body   value=portal.body.admin.users.list /
   /definition

   definition name=portal.body.admin.users.list
 extends=portal.body.admin.users 
 put name=bodyContent value=/portal/admin/users/list.jsp /
   /definition

 And the list.jsp usings the display taglib tags:

   display:table width=90% name=%=UserMgmtBean.KEY%
 property=users scope=session
 requestURI='%=request.getContextPath() +
 /portal/admin/users/list.dbm%'

 ...

   /display:table

 In the layout JSP that ultimately includes the bodyContent value above,
we
 are using:

   tiles:insert attribute=bodyContent/

 which is comparable to the example that you suggest I try. So, I can
 honestly say that I have tried it and it works. :-)

 Without rummaging through the display taglib source, the traversal
through
 action mapping to action with forward to the tile definition that
ultimately
 displays our master page layout containing the leaf listing JSP is working
 to control sorting. So, the request parameters are getting through to the
 leaf listing JSP. Otherwise, the display tags wouldn't be responding to
 the request parameter settings that control how to sort the list contents.

 We are working with the version of Tiles integrated in Struts 1.1-b2.
Maybe
 you are working with a different version of Struts/Tiles. If so, that
might
 explain why something similar isn't working for you. In any case, it
sounds
 like you have a workaround for now.

   Hi,

   I think that you should be able to read a parameter request from
 inside any nested tiles. Although, I haven't tested it since a long
 time. Normally, the request parameters are preserved through include /
 forward (but not sendRedirect of course).
   Maybe a problem with your webserver ?

 You can also use  bean:define in conjunction with this to define a bean

 your JSP pages. You must be new to JSP development. I recommend taking a
 look at the JSP spec. In particular, section 2.8 of the JSP 1.1 spec lists
 the implicit objects available to all JSP pages.

Re: Tiles and parameters...

[Craig Tataryn]

Well, I am doing forwards from within my Action class by returning an 
ActionForward object to one of my tiles defs (site.forecast).  So for 
instance, in displayChartSummary.jsp, if I put a 
request.getParameter(fieldid) an error is raised stating:

/form/displayChartSummary.jsp(16,75) Attribute fieldid has no value'

So it appears that the request parameters do not get passed onto the tiles.  
Which brings me back to my original question, how do I pass the paramters on 
to the tiles, or does anyone have an acceptable work around that does not 
involve the user session.

Thanks,

Craig.

If you really are just doing forwards and includes, and no redirects, your

Re: Two Phase ActionClass

[Craig Tataryn]

Create hidden fields (html:hidden) on the loginWarning.jsp page with the
same name of the username and password fields.  So long as they are within
the html:form tag as the others, it should pickup the values from the
FormBean that were set in login.jsp.

Actually, you shouldn't even need the hidden fields, because the username
and password fields should still be set on the form bean associated with
loginUser.  This is the same action you are using for the Continue button.
So basically, inside the continue method as well as the continue else branch
of showWarningIfNecessary you should be able to dig those values out of the
form.

Let me know if that works for you,

Craig.

 Sean, not sure if I would recycle the login page to show the warning,
 instead I would have another page called loginWarning.jsp which showed
them
 a message and then presented a Continue and Cancel button.  The Continue
 button would send them back to the logon Action class and the Cancel
button
 would simply be a link back to the login.jsp page.

 However, I would change my Action class to a DispatchAction class and
setup
 things like they have in the DispatchAction API doc, in your case,
something

 like this:

 action path=/loginUser
type=my.package.LoginUserAction
name=subscriptionForm
scope=request
input=/login.jsp
parameter=action

forward name=warn path=/loginWarning.jsp/
forward success path=afterLogin.jsp/
 /action

 I would then have two jsps, one for logging in (login.jsp) and then the
one
 for warning (loginWarning.jsp), and I would code my DispatachAction class
as

 follows:

 import org.apache.struts.action.DispatchAction;

 public class LoginUserAction extends DispatchAction {
 //have one method named for each possible function name you will be
 //passing in the action parameter

 //invoked when our Action class is called with
action=showWarningIfNecessary
 public ActionForward showWarningIfNecessary(ActionMapping mapping,
 ActionForm form, HttpServletRequest request, HttpServletResponse response)
 throws Exception
 {
//if the user is already logged in
//return mappings.findForward(warning);
//else return mappings.findForward(success);
 }

 //invoked when our Action class is called with action=continue
 public ActionForward continue(ActionMapping mapping, ActionForm form,
 HttpServletRequest request, HttpServletResponse response) throws Exception
 {
return mappings.findForward(success);
 }

 }

 In login.jsp, you would have a hidden form field with a name of action
and

 a value of showWarningIfNecessary:

 html:hidden name=action value=showWarningIfNecessary/

 In loginWarning.jsp your continue button could just be a link to:
 loginUser.do?action=continue (or you could have a hidden field named
action
 like in login.jsp, but the value would be continue)

 And your cancel button could be a link to:
 login.jsp

 If you read the API doc on DispatchAction, this will all make sense.

 Hope that helped!

 Craig.

didn't work (I am using a Dynaform if that makes a difference).

 You will want to use a bean:write tag to display properties of a bean,
 plus the html:hidden tag (you are already using) to keep the data.

 I have a question on how to build a confirm screen in struts.  In the past
 I
 had my user enter data in one screen into text fields on a form.  Once the
 user clicks submit I would use hiddle fields on the next screen to save
the
 values and I would also display the values on the screen to??

 I see in struts I can use the hidden tag but how do I display the value
and
 also have it in a hidden tag

Re: Select Options

[Craig Tataryn]

Hi Johnathan, I think you are getting confused with how it actually selects
the value that the user intended.

Think of it this way:

html:select property=type
  html:options collection=someCollectionYouHaveSetInTheScope
property=value labelProperty=label/
/html:select

This means that when the form is submitted, the type parameter is sent to
your action class with the value that they selected from the options.
Because this is struts, if your FormBean happens to have a
getType()/setType() method on it, that property will be set at form
submission, and subsequently the html:select tag will get the value of
that property and make sure that the corresponding option is selected in in
the list.

The options tag is simple, you set the collection attribute to a collection
of objects which possess a getValue() and a getLabel() method, the
values of these methods are used in the resulting option tag for the
value attribute and the text that goes between the option/option tags
respectively..

Make sense?

Craig.

Re: Datasource Retrieval in 1.1 (Help needed)

[Craig Tataryn]

From ActionServlet.findDatasource() API docs:
Deprecated. Look up data sources directly in servlet context attributes

So I replaced my call to :
dataSource = getServlet().findDatasource(null);

with:
dataSource = 
(DataSource)getServlet().getServletContext().getAttribute(this.DATA_SOURCE_KEY);

And my datasource is retuned as null.

Anyone know what's going on?

The API says to use datasource stored in attributes.  Can someone give 
an example of how I might do this from within my execute method?  I want

As well, I believe you can have multiple datasources setup in

Hi Craig,

This question was already answered, look for the subject Connection
Pool Question(15/08/2002). Anyway, the code...


Then, in your action, you can access your datasource via:
execute(..)
{
DataSource ds = this.getDataSource(request);
}
...

Alternative Datsource Hot-potatoing...

[Craig Tataryn]

I was wondering if someone could give me a heads up on some alternative 
means for which to give my data access layer access to my datasource.

I don't really like the idea of my controller grabbing the Datasource, 
passing it off to my business layer, who in turn passes it along to my data 
layer.  I guess I'm sort of a purest, but I don't think the Business layer 
should know anything about the database, and that means it shouldn't even 
have methods that take connections or datasourses as parameters.

I think the only thing I like about the Controller passing along a 
connection to my business/data layer is the fact that I can first open a 
transaction before passing the connection along, and then I can commit the 
transaction when everything is done.  Thus my transactions are at the 
controller level, and can be managed there.

Back in my old VB/COM days, we had a sort of DB Utilities class which could 
be accessed from the datalayer.  You would ask it to give you a connection, 
and it would get it for you.  Should I make my own class for datasource 
access which is intitalized upon application start with the Datasource 
object found by struts?  Then the rest of my datalayer can simply use it?

Thanks,

Craig.

Three basic options exist:

* Hand a DataSource (I normally prefer to send a Connection instead, but
   either works) to your business logic method as a parameter to each call
   that needs it.  Advantage:  no binding to anything.  Disadvantage:  can
   be a pain to hand it around.

* Static methods ... Most DB connection pool implementations offer a way
   to retrieve a DataSource or Connection via a static method.  Advantage:
   no handing around extra method parameters.  Disadvantage:  ties you to
   that connection pool's APIs.

* JNDI resources -- All J2EE app servers (and some servlet containers like
   Tomcat 4) offer support for JNDI resources that are accessible to your
   business logic directly like this:

 import javax.naming.Context;
 import javax.naming.InitialContext;

 InitialContext ic = new InitialContext();
 Context ctx = (Context) ic.lookup(java:comp/env);
 DataSource ds = (DataSource) ctx.lookup(jdbc/EmployeeDb);

   where jdbc/EmployeeDb is a resource reference you have declared in
   your web.xml file.  Advantage:  No parameter passing, no connection
   pool API lock-in.  Advantage:  configuration of the data source is
   external to your webapp (it's done with the server configuration
   capabilities).  Disadvantage:  container must support this.

For info on how to use the third option in Tomcat, see:

   
http://jakarata.apache.org/tomcat/tomcat-4.1-doc/jndi-resources-howto.html

(NOTE -- if you're going to use Tomcat, definitely go for 4.1; 4.0's
support has problems for many users).

Re: Question about Action Forms and input para

[Craig Tataryn]

1) Look at the code snap from struts-config.xml below, what is the input 
use
for?

actionpath=/page2
type=john.sample.Page2FormAction
scope=request
name=logonForm
input=/page2.jsp
forward name=next  path=/page1.jsp/
/action

Usually when I need to know something about struts-config.xml I look to the 
dtd.  Goto the URI provided at the top of the struts-config.xml file in the 
!DOCTYPE element: 
http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd.  It is pretty 
well documented.  Here is what it says about the input parameter:

input
Module-relative path of the action or other resource to which control should 
be returned if a validation error isencountered. Valid only when name is 
specified. Required if name is specified and the input bean returns 
validation errors. Optional if name is specified and the input bean does 
not return validation errors.


2) I have a question now about the formbeans and forms. A user enters data
into page1 and page1 data goes to the ActionForm page1Form.  After I check
some data I would like to goto page2 but page2 uses page2Form which is not
the same bean.  How do I make the new bean. move the data from the first
bean to the new bean?

I would probably just use the same formbean for both pages.  Just extend the 
formbean to encompass the new properties you need for Page2.

As mentioned elsewhere today, I've been using this ConnectionAdaptor:

http://cvs.apache.org/viewcvs.cgi/jakarta-commons-sandbox/scaffold/src/java/org/apache/commons/scaffold/sql/

But I'd wouldn't mind refactoring it into more of a DataSource manager, 
with the functionality seen in Struts 1.1. The idea being you could 
register several different DataSources, and then have the business layer 
say I want this one, or just give me the default (null) one.

Isn't that basically option 2?

The only disadvantage is that, unless you're careful, your DataAdaptor
class will be dependent on Struts unless you make it have a static
setDataSource() method or something.  But you're still tying your business
logic classes to the presence of DataAdaptor in every program that uses
this approach (which may or may not be a big deal).

I hear where you are coming from.  In the VB/COM app I was involved with, 
all our DB transactions were handled by MTS.  The stack thing seems 
interesting, but how do you allocate one stack per request?

You wouldn't happen to be able to share any of the code you speak about in 
your 2nd method can you?

Thanks,

Craig.

I've been grappling with this myself and I came across a couple other 
issues which may be worth consideration.

I thought that it was import for my business methods to be re-entrant and 
support transactions appropriately. This seems to be one of EJB's 
successes. A practical scenario is: the controller calls method A which 
calls method B; the controller also calls B directly. Each method may begin 
a transaction if it's a new request from the application, but should only 
commit the transaction and return the connection back to the connection 
pool once the control is passed back to the application.

Passing the connection in at the application layer does seem to address the 
problem but doesn't separate concerns particularly well.

I considered two other options:
1) a proxy which maintains a reference to the connection pool and handles 
getting and releasing the connection from the connection pool; or
2) The solution I've settled on for the moment is having the business 
methods have access to a connection pool and manage getting and releasing 
the connection by using a stack based reference counting scheme. The 
beginning of each transactional method starts with beginTransaction() and 
ends with finally {endTransaction();}, from within the transaction 
getConnection() always returns the same connection if the requesting thread 
is the same.

Both of these methods insure that each individual controller-request has 
access to the same connection for all database requests yet doesn't require 
the controller to specifically pass requests.

The more I work on this kind of thing, the more I appreciate EJB... 
something that I thought I'd never say.

Re: Two Phase ActionClass

[Craig Tataryn]

Sean, not sure if I would recycle the login page to show the warning, 
instead I would have another page called loginWarning.jsp which showed them 
a message and then presented a Continue and Cancel button.  The Continue 
button would send them back to the logon Action class and the Cancel button 
would simply be a link back to the login.jsp page.

However, I would change my Action class to a DispatchAction class and setup 
things like they have in the DispatchAction API doc, in your case, something 
like this:

action path=/loginUser
   type=my.package.LoginUserAction
   name=subscriptionForm
   scope=request
   input=/login.jsp
   parameter=action

   forward name=warn path=/loginWarning.jsp/
   forward success path=afterLogin.jsp/
/action

I would then have two jsps, one for logging in (login.jsp) and then the one 
for warning (loginWarning.jsp), and I would code my DispatachAction class as 
follows:

import org.apache.struts.action.DispatchAction;

public class LoginUserAction extends DispatchAction {
//have one method named for each possible function name you will be
//passing in the action parameter

//invoked when our Action class is called with action=showWarningIfNecessary
public ActionForward showWarningIfNecessary(ActionMapping mapping, 
ActionForm form, HttpServletRequest request, HttpServletResponse response) 
throws Exception
{
   //if the user is already logged in
   //return mappings.findForward(warning);
   //else return mappings.findForward(success);
}

//invoked when our Action class is called with action=continue
public ActionForward continue(ActionMapping mapping, ActionForm form, 
HttpServletRequest request, HttpServletResponse response) throws Exception
{
   return mappings.findForward(success);
}

}

In login.jsp, you would have a hidden form field with a name of action and 
a value of showWarningIfNecessary:

html:hidden name=action value=showWarningIfNecessary/

In loginWarning.jsp your continue button could just be a link to:
loginUser.do?action=continue (or you could have a hidden field named action 
like in login.jsp, but the value would be continue)

And your cancel button could be a link to:
login.jsp

If you read the API doc on DispatchAction, this will all make sense.

Hope that helped!

Craig.

Subject: Two Phase ActionClass
Date: Fri, 6 Sep 2002 20:14:37 -0400

Within my logon ActionClass, I want to check the user's user id/password 
and
whether they are currently logged on anywhere else.  If they are logged on
elsewhere, I want to go back to the logon page to warn them and give them a
chance to continue or to bail.  If they continue, I want to skip over the
check whether they are logged on elsewhere.  I'm struggling with how from 
my
logon.jsp page I can instruct the logon action to one thing one time and
another thing another time.  I was thinking maybe the ActionMapping
parameter, but I don't really know how to use it.  I'm searching.  Can
someone give me a good way to do what I'm trying to do?  Should I go to a
different ActionClass instead of trying to use the same one?

Also, I was going to return the warning to the user in ActionErrors.  Is
there a way I can poll the error from the jsp (logic tag?) and then if it's
this warning put a yes/no form on the logon page?  Or should I warn them on
a different page?  I do want other ActionErrors to display without the
yes/no form (e.g., username required.)  Thanks.

Re: Alternative Datsource Hot-potatoing...

[Craig Tataryn]

Let me add some context here: tataryn:craig/ :-)

And some more:

In our VB/COM app, our business layer never really knew where data was 
comming from.  And I'm not just talking about what database the data was 
coming from, I mean it didn't even know if the data was coming back from a 
flat file, a queue or a database.  We achieved this by only returning the 
serialized data of the object which were reinflated into our business 
objects upon retrieval, so it looked something like this.  And we made a 
little routing manager that figured out what DataObject should be 
instantiated for a business object.

Here is the definition for let's say the clsEmployee business object's 
retrieve function:

Public Sub Retrieve(EmpID as String)
Dim da as IDataObject
Dim rm as RoutingManager
Dim colFields as Collection
Dim colFilters as Collection
Dim vPropBag as Variant

'Ask the routing manager what data object to instantiate
Set rm = new RoutingManager
'this looks up in a map what the CLSID of the data object
'associated with the business object clsEmployee is, it then
'instantiates this object and passes it back. So, if sometime down
'the road we need to retrieve employees from an XML file, we would
'simply update the map that the routing manager feeds off of for the
'bEmployee.clsEmployee entry and point it to the new Dataobject.
Set da = rm.getDataObject(bEmployee.clsEmployee);
'
'build both the fields collection (i.e. the fields you want returned)
'and the filters collection. For this example we want to
'add empid = value to the filters collection, we never actually added
'sql stuff in the business layer, we just added tokens which were
'transformed into SQL (maybe) in the datalayer from the contents of
'the fields and filters collection
'.

'now ask the datalayer object to get us the object from the database
vPropBag = da.retrieve(colFields, colFilters)
'grab the non datasource centric property bag and have this object
'inflate itself with it
Me.Deserialize(vPropBag)

'we had to do all this messy serialization/deserialization because
'sending objects accross process or physical boundaries was not as
'straight forward in COM as it is in Java.  The vPropBag would most
'likely just be a buch of field=value strings, something COM serializes
'natively.

End Sub

So, barring all that, I could reuse this architecture above, coding a data 
object for each business object and having it grab data by whatever means 
necessary, and because it is so abstracted, I could write a dataobject to 
use the native API of a connection pool and never have to rewrite a Business 
object if the new Datastore were to change to an XML file (probably does not 
need a JDBC connection ;).

Where I was getting lost was, how do I get a connection from the connection 
pool all the way down to the bottom level Data layer object?  I think I have 
the answer in that I could just have a kind of central static class that is 
initialized with the Struts Datasource on web app startup, and the Datalayer 
objects that need to get a connection to a database in order to manipulate 
data, could simply ask for it via the static methods of this class.

Memories

Thanks!

tataryn:craig/

P.S. I am without static IP, and thus computer-programmer.org tutorials are 
down.  I should be getting a static IP in about a week!  Hopefully by then I 
will have played around with 1.1 long enough to revise my tutorial!

  Thanks Ted, I'll check it out.  But just out of curiosity, why would you
  ever want your Business Layer to know about Datasources?
 
  Craig.

This Craig stuff is going to get confusing :-).

The strategic issue, IMHO, is that you want business layer classes to know
the absolute minimum information possible to achieve its objectives.  In
the particular case at hand, the minimum possible knowledge would be
what java.sql.Connection to use for their JDBC activities.  If you're in a
batch-mode single threaded application, why would you want to go to all
the effort to establish a DataSource object, when you'd only ever use a
single Connection from it?  If you're going to pass in a reference to a
JDBC-something object, it seems better to me that you pass a Connection
instead -- that way a batch app can pass the one-and-only Connection it
creates, and the business logic layer is none the wiser.

Datasource Retrieval in 1.1

[Craig Tataryn]

The documentation still lists the old way of how to retrieve a datasource 
which has been setup in struts-config.xml using findDatasource();

The API says to use datasource stored in attributes.  Can someone give an 
example of how I might do this from within my execute method?  I want to get 
rid of my deprecation warnings for findDatasource()

As well, I believe you can have multiple datasources setup in 
struts-config.xml.  The default datasource being keyed by 
org.apache.struts.action.Action.DATA_SOURCE_KEY.  Could someone point me to 
an example of multiple datasources and how to setup keys for each?

Thanks,

Craig.

Re: [OT] EasyStruts and location of the generated Action file (URGENT)

[Craig Tataryn]

I too use the Tomcat  Easy Struts plugins for Eclipse.  In fact I would say 
they go hand in hand.

Typically this is what you do:

Install the Tomcat plugin, go into Window-Preferences-Tomcat and tell it 
where your tomcat base directory (CATILINA_HOME if you will) then create a 
new Tomcat project.  This ensures that your server.xml file will be setup 
properly so that a new context is added which points to your 
eclipse/workspaces/projectName/WEB-INF/ folder and your sources will be 
compiled to the proper directories.

If you need to stick jars in the WEB-INF/lib directory, right click on your 
project in the Java perspective (top most node) and choose Properties-Java 
Build Path-Libraries-Add External JARS.  Add the jar file, and the next 
time you refresh your WEB-INF/lib directory in eclipse you will see the new 
jar file appear there and you can use it's classes in your servlets.

Sound good?  So it just seems like you never started your project off as a 
Tomcat project before using the Easy Struts wizards.  Like I said, the 
Tomcat project container ensures that Tomcat knows where your classes are 
and it also ensures that the WEB-INF directory structure is created and 
updated for your project.

RE: ActionForms

[Craig Tataryn]

Here is an example of how to use DynaActionForm:

In struts-config.xml under form-beans tag:

form-bean name=loginUserForm 
type=org.apache.struts.action.DynaActionForm dynamic=true
   form-property name=userName type=java.lang.String /
   form-property name=password type=java.lang.String /
/form-bean

In the controller's execute method you have setup for this form:

public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
   DynaActionForm loginUserForm = (DynaActionForm) form;
   String userName = form.get(userName);
   String password = form.get(passWord);
}

Now the local variables userName and password would have the values entered 
by the user on the loginForm.

Make sense?

 I created a Plug-in to initialize a connection to a proprietary Data

 Worked out pretty well - gives me the ability to have connection pooling

The Struts controller knows what form bean to instantiate
   because you put
   a form bean name reference in your action mapping.  The
   mapping must contain
   the URL for your action.  In your JSP html:form tag, you
   reference an
   action's URL.  The controller simply matches this URL to your
   form bean
   reference through the actionMapping, then grabs the form bean
   class type
   from your form-bean declaration in your struts-config, and
   instantiates
   that class to populate with values from your request.  If you
   have no form
   bean reference in your action mapping, then you cannot use an
   html:form
   tag which refers to that action mapping's URL, as Sri already
   pointed out
   below.
   
b.t..w, if you had take the time to RTFM since yesterday,
   you could have
   answered your own question and then some.  The Struts user
   manual is a nice
   quick start for configuration, and the JavaDocs are quite
   comprehensive.
   Click on a package, then it's description, and you will get plenty of

Alrighty, really have been out of the loop for the last year w.r.t Struts, 
last time I used it was pre-1.0.  However, I will be using it on a project 
shortly and I have been brushing up.  Can you help me with this query?  I 
have set a simple demo where I have made a loginUser Action, who's input 
attribute is /form/loginUser.jsp.  Inside the execute method of this 
action, I simply return mappings.getInputForward();

Fair enough typically in my controller I might have some logic to figure 
out if the user was valid, and if they are I would forward them to some 
other handler, if they were invalid I would set some error messages and 
then do what I did above with the getInputForward() method.

However, I then did this in my browser:

http://localhost:8080/mywebapp/form/loginUser.jsp and it worked!  How did 
the Struts controller know what form bean to create for that loginUser.jsp? 
  Is it because I have loginUser.jsp as my input attribute of the action?  
What if I wanted to use the same input view (jsp file) for two separate 
handlers?  How would it decide then which form bean to create?

Also, can someone give me the Coles notes version on:
1) DnyaForms
2) Plugins

Thanks!

Re: Help me shake the cobwebs out...

[Craig Tataryn]

Yes, there is a form bean associated with my action mapping, as well as an
input attribute set to that jsp page I was talking about earlier.  I don't
believe the file was being loaded from the cache as I had a debug session
open in eclipse on my form bean and it tripped the getUserName() method :)

So, back to my original Q, how is struts making the association of that jsp
with the proper formbean?  Is it looking up the jsp page accross all action
mappings and if it finds a match on the input attribute it then sets up the

You haven't mentioned if there is *any* form-bean associated with this
action mapping.  You are forced to specify one only if you use the
html:form tag.

So, since you are simply refreshing the page it worked.

Did I miss something?

Alrighty, really have been out of the loop for the last year w.r.t
Struts,
last time I used it was pre-1.0.  However, I will be using it on a project
shortly and I have been brushing up.  Can you help me with this query?  I
have set a simple demo where I have made a loginUser Action, who's input
attribute is /form/loginUser.jsp.  Inside the execute method of this
action, I simply return mappings.getInputForward();

Fair enough typically in my controller I might have some logic to
figure
out if the user was valid, and if they are I would forward them to some
other handler, if they were invalid I would set some error messages and
then do what I did above with the getInputForward() method.

However, I then did this in my browser:

http://localhost:8080/mywebapp/form/loginUser.jsp and it worked!  How
did
the Struts controller know what form bean to create for that loginUser.jsp?
  Is it because I have loginUser.jsp as my input attribute of the action?
What if I wanted to use the same input view (jsp file) for two separate
handlers?  How would it decide then which form bean to create?

Also, can someone give me the Coles notes version on:
1) DnyaForms
2) Plugins

 The Struts controller knows what form bean to instantiate because you put
a form bean name reference in your action mapping.  The mapping must contain
the URL for your action.  In your JSP html:form tag, you reference an
action's URL.  The controller simply matches this URL to your form bean
reference through the actionMapping, then grabs the form bean class type
from your form-bean declaration in your struts-config, and instantiates
that class to populate with values from your request.  If you have no form
bean reference in your action mapping, then you cannot use an html:form
tag which refers to that action mapping's URL, as Sri already pointed out
below.

 b.t..w, if you had take the time to RTFM since yesterday, you could have
answered your own question and then some.  The Struts user manual is a nice
quick start for configuration, and the JavaDocs are quite comprehensive.
Click on a package, then it's description, and you will get plenty of
documentation, particularly with the tag packages.

 peace,
 Joe

Re: Help me shake the cobwebs out... (also http://www.computer-programmer.org/articles/struts/ is back up)

[Craig Tataryn]

That's ok Joe, I understand.

The one thing I do when I subscribe to a mail group is say to myself Am I
here to help myself or to help others?  Nine times out of ten it ends up
being both.  If I respond to someone's query I only do so if I legitimately
have something to contribute, I never respond if it is going to be
condesending.  When I dedicate myself to helping a mailing list, I answer
people's questions in hopes that they may one day answer some of mine.  Yes,
I should have queried the manuals closer, my bad.  Remember sarcasim should
be left for Usenet :)  If I respond with an RTFM type post, I usually
provide a link to the document I wish the user to read, or atleast a quote.
I know some people abuse this level of help, but on a whole it helps the
group.

In my RTFM'ing I understand the concept behind Dynaforms, but was wondering
if someone could provide an example?

And Plugins, still not clear on how/when I would use such a thing.  Is there
a specific example someone has at the top of their head?

Thanks,

Craig.

Re: newbie question

[Craig Tataryn]

Hi Anand, you will not be able to run a Struts application directly under 
Apache web server.  You need either do one of two things:

1) Dump Apache web server all together, but Apache is good for serving 
static pages so you may want to take option two:
2) Have Apache running along side of Jakarta Tomcat, to find out how to do 
that, read this: 
http://jakarta.apache.org/tomcat/tomcat-3.2-doc/tomcat-apache-howto.html.  
Basically what it amounts to is you let Apache know about Tomcat and you 
tell it which URL contexts will trigger Apache to pass the request along to 
Tomcat for processing.

So for instance if you might set it up so all requests to 
http://mysite.com/servlet get passed along to Tomcat, or perhaps you will do 
it by extension so that all files ending in .jsp will be handled by Tomcat.

Hope that helps,

Craig.

Hi,

I could make the strut example work on my server.. Redhat 7.1

My next goal is to just make this exmple work as it is from
my site which is say http://mysite.com

How can I do that?? Is that I have to copy all the struts-example
directory to my site root directory?? I am using Apache webserver.

My root directory for this site is /home/mysite

Thanks

Action object doesn't get attributes...

[Craig Tataryn]

Here is a question from a collegue of mine (see below).  Basically last year 
when they started using Struts on one of their web applications they could 
use request.getAttributes from their Action object and everything worked 
fine.  However, now it seems that they need to use an ActionForm object 
which isn't possible in this case since the form objects to be submitted 
change based on the user logged in.

Anyone have an answer?  I just saw a mail from Craig explaining that form 
parameter values are treated differently now than they were before, however 
he says they are using the same version of struts (1.0) as they did before.

Thanks,

/tataryn:craig

Original message:

For those of you who I asked already, I did some more testing and
included some more information:

Have any of you come accross the following?

It seems that the form attributes are not available to the struts Action
object unless they are put into an ActionForm. If they are not put into
an ActionForm (or if there is no ActionForm defined for the page) then
the data is unavailable to that Action object.

This did not happen in last years application (both are using the same
struts version). Is there some configuration setting that might be
causing this? Is the presence of ANY ActionForm that is defined on that
page mess up forms for which there is no ActionForm?

Thanks for any info you might have on this.

The request (and response) are passed to the Action as method parameters
-- so the request attributes are definitely available inside an Action's
perform() or execute() method.

Remember that request *attributes* are things that your application has
stored there.  If you're looking for the input information from the client
browser, you probably want the request *parameters* instead (which are
also available from the passed request instance).

RE: Best Practice for parsing an XML file for application confi gurationparameters?

[Craig Tataryn]

You can put all your properties in one file as well, lets call that file
config.properties

  2.  xml handle the structure data much better then properties file

data structure might be nice for communications between computers but for
users?
e.g.
RepositoryRoot=d:\
RepositoryAssets=assets
RepositoryViewPath=file://d:/repository/assets


Just to add, I like the format:

Repository.Root=d:\
Repository.Assets=assets
etc..

I suppose, if you ever wanted to goto XML at some point, you could just 
write yourself a nice little resource bundle manager that exposed the xml 
file in the same way you are used to using your properties file.

Re: Digester Question

[Craig Tataryn]

Anyone?

Subject: Digester Question
Date: Mon, 04 Mar 2002 14:19:07 -0600

I realize that the digester is now part of commons, but I figure there is
probably a lot of expertise here since it grew up in Struts.  I was
wondering if someone could help me figure out the easiest way to do this:

I have an xml document, that holds form data, I would like to use the
digester to populate my objects automatically.  A form file might look like
this:

forms
  form type=shopping-cart
 
  /form
  form type=calculator
  ...
  /form
...
/forms

Let's assume there are many forms...  I was wondering, without having to
load all forms into objects and then picking the one I want to use, I would
rather the digester only instantiate and populate an object for lets say,
the form node who's type attribute is calculator.

What's the easiest way to do this?  I don't think the digester can pattern
match on attribute values the way XPath does, so is there a programming
technique I can use to filter further?

Thanks,

Craig.

Re: Struts and Servlet Exec

[Craig Tataryn]

Bang on my friend!  That did it!  You were correct in assuming that I was 
behind an http proxy.  Updating the URIs for the dtds to the local servers 
did the trick.  That would explain why it took so long to add/reload the 
struts-example, it was timeing out on trying to lookup the dtds!

Thanks,  and thanks to Robert as well!

Hi Craig,

 Can't comment on the original problem but resolveEntity problem 
comes with
server not able to fetch the dtds from an external site (your server behind 
the
fire wall etc.,).  Copy, the following dtds to your webApp (or jsp root 
dir), you
should find them  in the struts distribution.

struts-config_1_0.dtd
web-app_2_2.dtdor
web-app_2_3.dtd  or both.

   And in the struts-config.xml where it says

!DOCTYPE struts-config PUBLIC
   -//Apache Software Foundation//DTD Struts Configuration 
1.0//EN
   htt://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd

replace  the following line filling the port and webApplicationName( 
name of
the app deployed, ex: strutsexample) variables.

!DOCTYPE struts-config PUBLIC
-//Apache Software Foundation//DTD Struts Configuration 1.0//EN
   
http://localhost:port/webApplicationName/struts-config_1_0.dtd

The dtd will be fetched from the local host instead of an external 
site.

Similarly add the local URL with the correct dtd to your web.xml file also.

- Hope this helps.

Computer-programmer.org tutorial...

[Craig Tataryn]

Well, hopefully I've exercised the demons out of my webserver.  Let me know 
if you see any anomolies w.r.t. the online presentation (some of the images 
were getting garbled).

http://www.computer-programmer.org/articles/struts/

If anyone has any webspace they would like to donate, I would love to 
offload the narration files to them.  My poor DSL connection doesn't have a 
large pipe for uploads.

Thanks,

Hi Graig,

Most Servers (Web  J2EE) have a session timeout setting. If used in
conjunction with form based (container managed) authorization, the 
container
will invalidate the session for you and pass control automatically to your
login screen once their session is invalidated.

 One approach would be to not let the session timeout.  The 2.3 servlet
 spec. allows you to set the timeout to -1, which means the session will
 never expire.

  Hi there, you probably have heard this question a million times
 before, but
  I couldn't really find anything in the archive which answered
 it.  So here
  it goes:
 
  We have an application for which we would like to use struts.
 This
  aplication allows users to enter performance evaluation
 information on
  employees in the firm.
 
  I would like to know this:  The user starts a performance
 evaluation, and
  half way through decides to go grab a bite to eat, comes back
 and finshes
  the evaluation, when he/she hits the save evaluation button
 their session
  is going to be kaput.  Let's assume that the evaluation is a
 wizard type
  application and relied heavily on an ActionForm class to store
 the
  information entered on each page.
 
  How do you overcome this problem?  Make sure to store all their
 previously
  entered performance evaluation data in a hidden field on the
 client side?
 
  Any help would be greatly appreciated.

Hi

session.invalidate() comes to mind...

another way would be to persist the information so far entered (under some
artificial key) and use a cookie to reget that key from the user's browser
as soon as he comes back. With this you can let the session expire and 
still
have the information ready...

hope this helps

RE: What happens when our session expires?

[Craig Tataryn]

There you go!  That sounds good.  So I'm assuming (bare with me, I haven't 
done much with session time outs) that you code some type of event procedure 
which is kicked off when the session times out?  You can then do cleanup 
stuff at this point?  How do you get at your form bean?  If memory serves 
(and it's been a while), your form beans are always passed to you as a 
parameter.  Unless you can get at them some how through the session object?

Thanks,

Craig.

Store the data in a database on session timeout; restore it when the user
comes back (requires a login or a persistent cookie).

Hi there, you probably have heard this question a million times before, but
I couldn't really find anything in the archive which answered it.  So here
it goes:

We have an application for which we would like to use struts.  This
aplication allows users to enter performance evaluation information on
employees in the firm.

I would like to know this:  The user starts a performance evaluation, and
half way through decides to go grab a bite to eat, comes back and finshes
the evaluation, when he/she hits the save evaluation button their session
is going to be kaput.  Let's assume that the evaluation is a wizard type
application and relied heavily on an ActionForm class to store the
information entered on each page.

How do you overcome this problem?  Make sure to store all their previously
entered performance evaluation data in a hidden field on the client side?

That's right.  Check out the javax.servlet.http.* API.  You want to 
register
the moment the user becomes unbound from a session so you can write the 
form
values to the database (these would be stored as session attributes and
updated as the user moves from field to field in the forms or from form 
page
to form page.  Any object that implements the HttpSessionBinding Listener
interface is notified when it is bound and unbound from a session.  So, for
example, create a helper class or stick a helper method in your controller
servlet to do something like:

public void valueUnbound( HttpSessionindingEvent event) {
 [plug session.getAttribute() returns into update parameters on your
Statement().update() method call through your Connection() String]
}

This works because whenever this interface is implemented, its valueBound()
and valueUnbound() methods are invoked whenever a session begins and
whenever it ends, respectively.  This is how many persistent shopping cart
apps work (e.g., see the JavaOne shopping cart at java.sun.com - it 
persists
across sessions).

RE: What happens when our session expires?

[Craig Tataryn]

Thanks! Would there be a way we could manually end a session (i.e. at 
logoff?)?

I would say that at some point (perhaps 24 hours) we would want the session 
to expire, I imagine if we never expired sessions we would get into some 
really bad performance issues...

One approach would be to not let the session timeout.  The 2.3 servlet
spec. allows you to set the timeout to -1, which means the session will
never expire.

 I've seen some talk about this in the struts-dev group can somebody point me
 to where i can read more about it.

 I'm working on a framework that allows a struts developer to reuse certain
 wizard based pages where the wizard doesn't change, but the start and end
 points do i.e. Basically a way to plug in a use case into other use cases.
 The result of the wizard would be a bean (foreign key) that would be
 assigned to a bean that requested the service of the wizard.

 I would like to find out if the 'workflow' stuff is for this situation

 Thanks.

Re: flow control

[Craig Tataryn]

You can definitly do this in Struts as it stands (correct me if I'm wrong).
What will help this along is the Workflow Processing TODO in the TODO 1.1
document on the struts homepage.  When that is completed you will be able to map
out this flow in some graphical type means.

 Hello you beautiful people,

  I am a newbie to struts and our company has to decide whether to go
 with struts or not. I have a very important question that will decide the
 fate of our project...

  Basically we want to control the flow (of the user) when he goes to various
 pages.

 For example i have 5 jsp pages a.jsp ,b.jsp, c.jsp, d.jsp and e.jsp

 The order of flow is  a-b-c-d-e. The user has to strictly adhere to this
 flow. The user can't jump from a to c or d to e  or e to a or d to c. etc..

 Is this possible using struts ? If so, what steps do i have to go through to
 make sure that the user can adhere to this flow ? Thanks a lot.

 cheers,
