Re: Multiple submit buttons solution

[Peter Severin]

Hi Larry,

This exactly the situation my solution would help. Eeach submit button would
have a different name but this would be transparently handled by struts. E.g.:



Convention would be that underscore(or any other char)  is parameter name/value
separator. So the parameter name 'action_save' would be transformed into
action=save. In the action form I would have a field named 'action' which would
take the value 'save' or 'saveAs' .

Regards,
Peter.

RE: Downloading files locally

[Nick Thomson]

You can use a servlet push to accomplish this.  Change the content type in
the response header to text and then use print.out statements to output each
line of text.  This is a very general explanation so I leave it up to you to
research the specifics.  BTW you can use this technique to output about any
type of file; just change the response header content type to what you need.

LookupDispatchAction - action parameter not submitted when using - IE 6

[Matt Raible]

I'm trying to use the LookupDispathAction and when I have my buttons like so:


  


  


which renders as:




For CSS and other purposes, I want to use the HTML 4.0  tag instead,
but the following always results in the first button's action being called,
rather than the appropriate one.

Upload
Delete

I just test this in Mozilla 0.9.8 and it works fine, but problem still exists
in IE 6.  Any ideas/workarounds?

Thanks,

LookupDispatchAction - getKeyMethodMap documentation

[Matt Raible]

In the javadocs for the LookupDispatchAction, it states that you need to
override the following method:

  protected Map getKeyMethodMap(ActionMapping mapping,
   ActionForm form,
  HttpServletRequest request) {
  Map map = new HashMap();
  map.put("button.add", "add");
  map.put("button.delete", "delete");
  return map;
  }


However, the method in the class has no parameters.  I downloaded the latest
nightly build and checked.  Is this a bug?

Also, can I override this method in my base class - will that work for all
subclasses?

Thanks,

Matt

Ted,
on the 'doing fancy stuff with ActionServlet' front. I was thinking this 
week (bad sign) about adding a Struts 1.0.x compatible implementation of 
the action servlet into the 1.1 build that had all the same extension 
points as 1.0, and used a special RequestProcessor etc to route 
processing back to it.

Does this make some sense?

RE: design flaw if using a template...

[Keith Chew]

Hmm, but I don't want to put anything to the template.jsp. I just want the
template to include the news.do. If what you are saying is correct, I should
really be using .

However, I'll give all 3 methods a go. I am sure you are correct.

Great stuff! Thanks Matt

Keith, they're not the same thing, by any means. As you said, if you use
your method:

you get a "too many servlet includes `/template.jsp'" error. This is doesn't
really suprise me at all - you're basically trying to use something which
blatantly isn't a template, as a template.

However if you use the method I outlined in my examples, i.e. you "put"
content into a template, whether this content is a .jsp or an action mapping
url - it works.

Honestly, just use  as it is documented and your problems will
be solved.

In template.jsp, you can either go:

Matt, thank you very much for trying this out. I appreciate the time you are
spending to help me track the problem.

Can you give this a go:

In the address bar, type a *.do address, eg
http://localhost:8080/test/page1.do

This will call Page1Action, which forwards to page1view.jsp

In page1view.jsp, it will have your template which inserts shownews.do.

I believe this will fail.

If you have a JSP in the address bar, it's fine. But with a .do, it's not.

Design issue

[Parimi Srinivas]

Hi all,
I want to validate my design. 

One of our applications caters to 3 OEM's. Application has three business
functionalities and each business functionality has 4 to 5 screens on an
average. The only difference between OEM's is LOOK and FEEL of the
application. To achieve different LOOK and FEEL for OEM's, OEM names are
mapped to 3 different aliases ( OEM1, OEM2 and OEM3) of action servlet.
Mappings of OEM name and action servlet alias are stored in an xml mappings
file. When users belonging to a particular OEM access application for the
first time,  OEM name is retrieved depending up on the action servlet alias
and stored in a new session. Appropriate JSP's are processed depending up on
the OEM name stored in the session. 

There is no user authentication screen in the application. 

If a new OEM is added to the application, following steps are followed -
1. a new servlet alias is created
2. Create a mapping between OEM name and action servlet alias.
3. Create JSP pages for new OEM.

Any suggestions,

template which is completely different:


You need to do the following:
1. Create an action mapping like this in struts-config.xml:

2. Create your template file "/mytemplate.jsp" something like this:
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>




3. Create your page "/thePage.jsp" something like this:
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>





4. Open up http://mymachine.com/mypage.do and it should show the result of
your 2 actions that you "put" in step 3.

Hope this is clear enough.

Matt.

Matt, thank you very much for trying this out. I appreciate the time you are
spending to help me track the problem.

Can you give this a go:

In the address bar, type a *.do address, eg
http://localhost:8080/test/page1.do

This will call Page1Action, which forwards to page1view.jsp

In page1view.jsp, it will have your template which inserts shownews.do.

I believe this will fail.

If you have a JSP in the address bar, it's fine. But with a .do, it's not.

I have using the 26 Feb 2002 snapshot.

Hi Matt

Yes, that's exactly what I want. In fact, I have the same code that you have
given below.

But Struts does not allow it. It complains that the request is already
commited and cannot forward twice.

Can someone try this out for me please? Maybe I have missed out something...

If this can be achieved, it'll be so easy to mix and match your Actions, put
them as links in a page or in the template.

My apologies if I'm misunderstanding your point but if you're concerned that
the elements that you "put" into your template are not going through the an
xxxAction then why not put the URL for the action in instead of a .jsp? This
way your ShowNewsAction is following the same flow as any other content.
E.g.

Hi Ross

Good comments.

You see, with custom tags, there are several problems:
- For each different parts of the template, I need to create a custom tag
- This custom tag is actually what an xxxAction class is meant to do, ie
retrieve data from a database and prepare the data for view
- If I later decide not to put news in the template and put it in a separete
page, I need to port the taglib code to an xxxAction class. Not very
flexible.
- taglibs from Struts point of view, only renders data for viewing. It
should not be performing model work, which should really be in the xxxAction
class.

So, I can see that Struts was designed to handle "user invoked" actions, not
"code invoked" actions.

Any more thoughts?
Keith

yes that's true, try to check whether the web.xml file is well formed or not
as well as check if the web.xml is valid(i mean check against the DTD

I ran into the same problem once, first time it was uri issue next time I

if the web.xml file has the following taglib declaration

it expects the struts-template.tld under the WEB-INF directory, check if you

Action execute isCancelled

Let me bounce this design (that might extend Struts 1.1 functionality) for 
suggestions/code snippets:

Q1.I want to create a base Action that "developers" will use instead of Action.
In baseAction.execute() I want to have logic that will call:
executeRet() to populate the formBean
executeUp() to validate and save the formBean
executeDel() to request a delete from a formBean
and executeNew() to insert a row in a formBean

How do I do this?

I like isCancelled() on Action, that tells me the user clicked cancel button design.

One possibility?

or 


Then in baseAction, do a request.getParameter("X")? and call the right method?
Is there a bette way to find out button clicked?

Is there another way?

Q2. Also... I want to call Save,New,Delete from a menu sometimes and not a button. How 
would I do it then?
Have a SaveAction that would detect the form or action used and then ask the right 
form to save?

Q3. If the user changes a page, and clicks on menu to go to another page, how do I pop 
up a message saying changes made/ do you want to save? And then go to the proper page 
requested orginally?
Should I code the button and/or menu to to call a javascript that would check for

Put another way, I wouldn't want to have to set up a bean with "setNews" and
"setMemberCount" when I have no intention of allowing my application to edit
those values.

Subject:design flaw if using a template...

Hi

Struts provides us with a nice MVC architecture, where:
- a user's click maps to an Action
- based on the results, the user is forwarded to the view

Now, I have a template.jsp which all pages will use. The template will
contain some views that are common to all pages, eg:
- Latest News
- Site visits
- Member count

To retrieve these information, it gets them from the database. However,
there is no user click to invoke the action. This is where the limitation of
Struts comes in. Let me explain:

In the template.jsp, we can have:



In news.jsp we can access the database and retrieve the news for display.
This breaks the MVC pattern, since the view is accessing the model.
Alternatively, we have have this in the template.jsp:



This will call the NewsAction which accesses the database, and forwards the
results to the news.jsp for display.

This is a great concept, but it does not work. Struts does not allow
multiple forwards (this happens when the current page is already a .do).
Here's an example:
(1) User clicks on viewUserDetail.do
(2) ViewDetialAction forwards to user.jsp
(3) In template.jsp (used by user.jsp), news.do invokes NewsAction, and it
forwards to news.jsp

This is a double forward, which res

Hi Matt

Yes, that's exactly what I want. In fact, I have the same code that you have
given below.

But Struts does not allow it. It complains that the request is already
commited and cannot forward twice.

Can someone try this out for me please? Maybe I have missed out something...

If this can be achieved, it'll be so easy to mix and match your Actions, put
them as links in a page or in the template.

My apologies if I'm misunderstanding your point but if you're concerned that
the elements that you "put" into your template are not going through the an
xxxAction then why not put the URL for the action in instead of a .jsp? This
way your ShowNewsAction is following the same flow as any other content.
E.g.

Hi Ross

Good comments.

You see, with custom tags, there are several problems:
- For each different parts of the template, I need to create a custom tag
- This custom tag is actually what an xxxAction class is meant to do, ie
retrieve data from a database and prepare the data for view
- If I later decide not to put news in the template and put it in a separete
page, I need to port the taglib code to an xxxAction class. Not very
flexible.
- taglibs from Struts point of view, only renders data for viewing. It
should not be performing model work, which should really be in the xxxAction
class.

So, I can see that Struts was designed to handle "user invoked" actions, not
"code invoked" actions.

Any more thoughts?
Keith

Consider rethinking the philosophy that all data rendered in the JSP must
come from an ActionForm.   In my mind the ActionForm generally represents
the editable data for the page displayed to the user.  There's no problem
with displaying data from other sources on the same page - especially read

Struts Web App Challenging user with BASIC Auth

[Satish Jeejula]

Hi All,

I have a web application using struts running under apache\tomcat3.3
configuration. I want to make this app challenge the user  using HTTP BASIC
Auth scheme. 

The admin context that comes with tomcat does implement this. But the admin
is not using struts.

I have added security-constraint element to my web.xml file for my
application. But still it does not challenge me?

Is there anything else that I need to configure for the application using
struts to challenge??

Any pointers that will lead me to a solution.

Any help is appreciated.

Thanks,
Satish

Tiles does not solve the problem. As far as I can see, Tiles makes it easy
to configure your presentation pages, and pass variables between templates.
It makes your presentation design work more OO.

However, my issue is more of an archietecture problem, not a presentation
problem.

RE: "Best Practice" for parsing an XML file - Code Review Requested

[Matt Raible]

I've completed this task - however, it would've been MUCH easier to just use a

because I had to write a lot of code to grab 4 simple varaibles.

private synchronized void loadConfig() throws Exception {

// Initialize our configuration object
config = new Configuration();

logCat.debug("Looking for " + configFile + " in " +
Constants.USER_HOME);

// Acquire an input stream to our configuration file
InputStream is = new FileInputStream(Constants.USER_HOME + configFile);

// No file found in user.home
if (is == null) {
logCat.debug("File not found at " + Constants.USER_HOME +
configFile
+ " - looking in application's WEB-INF directory");

// Look for config.xml in WEB-INF
is = getServletContext()
.getResourceAsStream("/WEB-INF/" + configFile);

if (is == null) {
throw new Exception("Configuration file '" 
+ configFile + "' not found in '" 
+ Constants.USER_HOME + "', nor in '/WEB-INF/'");
}
}


// Get the XML Document
DocumentBuilderFactory builderFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = builderFactory.newDocumentBuilder();
Document doc = builder.parse(is);

// close the input stream
is.close();

// get the repository root
NodeList rep = doc.getElementsByTagName("root");
Node node = rep.item(0);
Text rootDir = (Text) node.getFirstChild();
config.setRepositoryRootDir(rootDir.getNodeValue());

// get the assets directory
rep = doc.getElementsByTagName("assets");
node = rep.item(0);
Text assetDir = (Text) node.getFirstChild();
config.setAssetDir(assetDir.getNodeValue());

// get the assetView path
rep = doc.getElementsByTagName("viewPath");
node = rep.item(0);
Text viewPath = (Text) node.getFirstChild();
config.setAssetViewPath(viewPath.getNodeValue());

// get the assetView path
rep = doc.getElementsByTagName("default-passing-score");
node = rep.item(0);
Text minScore = (Text) node.getFirstChild();
config.setAssessmentMinScore(new
Double(minScore.getNodeValue()).doubleValue());

logCat.debug(config.toString());

Hi,

I try to do an iteration on a vector. When this vector contains only 
Strings, the iteration works well. For that, I use the following piece of code:

But, when I try with a vector containing custom objects, it doesn't work :(
For example, I have a Vecor of Element. Element is a bean which contains 2 
attributes (2 String named: id and name)

nesting: iterate cannot find attrribute

[Elijah Jacobs]

Hi All,

I'm trying to do a simple iterate .. it's even simpler that than one I
download from Arron Bate's site since the formbean has the reference to the
list of objects.

In my FormBean I have:

private Vector x = null;

public Object[] getX(){
return  this.x.toArray();
}
 public void setX(Vector x) { this.x = x; }



I first set this attribute to some value in my action class.  In my jsp page
I have:


 something


Note: I put this right under the  tag since it's in the
FormBean class.

The problem is that weblogic is not finding the getter for property "x".

I get the error:
javax.servlet.jsp.JspException: No getter method for property x of bean
auctionForm

Does anyone have any suggestions on how I can go about solving this?

thanks for any help in this,
- ej

I18n for number formatting on Struts

[@Basebeans.com]

Subject: I18n for number formatting on Struts
From: "Eduardo André Mallmann" <[EMAIL PROTECTED]>
 ===
Hi all,

I'm using Struts on a project in the company. The Internacionalization for
the messages and labels on the Web pages work fine and we didn't have much
problem.

But for the internacionalization of some number formats (write 1.000,00
instead of 1,000.00, etc) we had to set somethings hard coded because we
didn't find support on Struts for this kind of thing.

Do you know if it's possible to let Struts do by himself the formatting of
numbers, dates, etc. automatically using the Locale catched from the
session, like it does for the messages and labels?

Thanks in advance,

Eduardo

I have a struts web application which uses container managed authentication.

When a user is logged into the application and the session times out, the
next user-initiated action will result in the login page being displayed
(the j2ee container makes this happen).  

How is it possible to tell that the reason that the user was directed to the
login page was because the session timed out and not because it was the
users first attempt at accessing the resource? 

I would like to display message to the user indicating that the reason they
are in the login page is the result of a session timeout.

I am currently constrained to use of the Servlet 2.2/JSP 1.1 spec.

design flaw if using a template...

[Keith Chew]

Hi

Struts provides us with a nice MVC architecture, where:
- a user's click maps to an Action
- based on the results, the user is forwarded to the view

Now, I have a template.jsp which all pages will use. The template will
contain some views that are common to all pages, eg:
- Latest News
- Site visits
- Member count

To retrieve these information, it gets them from the database. However,
there is no user click to invoke the action. This is where the limitation of
Struts comes in. Let me explain:

In the template.jsp, we can have:



In news.jsp we can access the database and retrieve the news for display.
This breaks the MVC pattern, since the view is accessing the model.
Alternatively, we have have this in the template.jsp:



This will call the NewsAction which accesses the database, and forwards the
results to the news.jsp for display.

This is a great concept, but it does not work. Struts does not allow
multiple forwards (this happens when the current page is already a .do).
Here's an example:
(1) User clicks on viewUserDetail.do
(2) ViewDetialAction forwards to user.jsp
(3) In template.jsp (used by user.jsp), news.do invokes NewsAction, and it
forwards to news.jsp

This is a double forward, which results in an exception.

Basically, I want to call



in the JSP. Has anyone done something like this?

RE: Application Scope Variables

[Farrell, Sarah]

Hello,

I was searching around in the struts-user list archives for the correct
getServletContext() syntax and found Robert's response to a post:
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg22768.html

I am trying to compile an ActionForm and I need to access the *application*
scoped bean (not a session bean).

I tried:

public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) 
{

Object o =
request.getSession().getServletContext().getAttribute("attribute_name");

}

And it won't compile:

[javac] C:\cvs
work\energizer\source\edu\cccs\energizer\SupplementalForm.java:280: cannot
resolve symbol
[javac] symbol  : method getServletContext  ()
[javac] location: interface javax.servlet.http.HttpSession
[javac] Object o =
request.getSession().getServletContext().getAttribute("attribute_name");
[javac] 

The difference btw what I'm doing and what Robert had suggested is that I'm
trying to do it within the ActionForm and not within the Action, but I can't
figure out why it won't work in the ActionForm.

RE: Session Timeout?

Do you use container managed authentication?
If so, where did you make this check?

My understanding is that the container will take control and send the user
directly to the login page with a new session in place (in the same way as a
new user login would).

Accessing values in hashMap through key with struts

[eugene neymark]

Hi!
Any clues to how to access HashMap through a key with struts?
Strut documentation is very vague on this subject.
here a sample of what i tried and it doesn't werk even though it compiles...


]" type="java.util.ArrayList"/>

so the above compiles but whn i try to iterate the  'arrayOfRoles' it says
that there is no collection. strangely enough there is no collection as i
can not even access the 'arrayOfRoles'  through the scriplet.

here's what i do instead and it worx but i want it to be purely in struts..


<% int id = ((User)user).getId();
   roles = (ArrayList)((HashMap)hashOfUsers).get("" + id);
for(int i = 0; i < roles.size(); i++){
%>
<%=((Role)roles.get(i)).getName()%>
<%}%>


Thanks !

m-m is not yet supported in an elegent way by Simper. In the docs I
mention 1-1 and 1-m but I don't mention m-m for this reason.

As a tempoary workaround to get going, create another field in your
portfolio_stock table, called "id", and use it as a (pseudo) primary-key
(assigning it unique values, etc, upon every insert). I know that m-m
tables shouldn't require a primary key field (other than a composite of
the foreign keys), but that's just what Simper requires at this point.

Because NeXt is an extension of the original tags, it uses whatever the
original tags use to get their logic happening. BeanUtils was adapted
for DynaBeans, all the tags use BeanUtils, and so therefore, all the
tags can use DynaBeans. Including the nested ones.

In regards to how everything fits together... a well based technology is
a well based technolgy. From java itself all the way up to the
construction of Struts itself. All done to a very high standard. You
look at some of the code in java's standard API's... some of it is
simply brilliant.

Re: nesting tags cannot find EmptyTag

[Arron Bates]

You're running an older version of Struts I take it (1.0, 1.01)?...

There's a jar made especially for these versions of Struts that doesn't 
have the extra tags like the empty tag.
Download "nested_tags_10.jar" (binaries), "nested_tags-src_10.jar" 
(source) from...
http://www.keyboardmonkey.com/struts

That should get it working. You will also have to replace the tld with 
that which comes in the jars, otherwise weblogic will still complain 
(All this is because weblogic parses and checks the tld's). The location 
and name of the tld's don't matter, as long as it matches the definition 
in your web.xml and JSP's etc.

Hopefully that will get you working.

Arron.

nesting tags cannot find EmptyTag

[Elijah Jacobs]

Hi All,

I am using nested-tag from Arron Bates. I have a working sample in my tomcat
webapp, but when I try to run that app with my weblogic 5.1 i get this
error:

java.lang.NoClassDefFoundError: org/apache/struts/taglib/logic/EmptyTag

I can't seem to find anything on the user group under "EmptyTag" and my
struts.jar is uptodate.

There is one difference in my webapp setup under weblogic...I put my *.TLD
right under my web-inf folder .. while in tomcat, the tuturial I got from
the web, has it under web-inf/taglib/ .. but I don't think that makes a
difference.

Any suggestions on how to go about solving this?

thanks in advanced,

I am using WebLogic 5.1 on Windows 2000

Re: how to edit an array of records with action forms?

[Arron Bates]

If you're on a nightly build, you'll have the nested extension already 
there. It will help you make light work of iterating objects.

For a pimer and tutorial, go here...
http://www.keyboardmonkey.com/struts

And for mor implementation detail for each of the tags, the Struts site 
has the most complete info.

Re: simper-NeXt

[Arron Bates]

Because NeXt is an extension of the original tags, it uses whatever the 
original tags use to get their logic happening. BeanUtils was adapted 
for DynaBeans, all the tags use BeanUtils, and so therefore, all the 
tags can use DynaBeans. Including the nested ones.

In regards to how everything fits together... a well based technology is 
a well based technolgy. From java itself all the way up to the 
construction of Struts itself. All done to a very high standard. You 
look at some of the code in java's standard API's... some of it is 
simply brilliant.

Re: Backporting mapped properties in Struts 1.0

[Peter Pilgrim]

FYI Here are my developer notes

*Backup the target files beforehand*

copy common-beanutils-1.2/**/PropertyUtils.java   to 
struts-1.0.2/**/PropertyUtils.java
copy common-beanutils-1.2/**/BeanUtils.java to struts-1.0.2/**/BeanUtils.java
copy common-beanutils-1.2/**/MappedPropertyDescriptor..java to struts-1.0.2/**/...

Well it basically compiles except two errors from Ant

compile.library:
Compiling 2 source files to 
/home/pilgpe/Products/jakarta-struts-1.0.2-src/target/library/classes

Note:

 uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.


Solution.
getAccessible() methods that belonged in PropertyUtils.java moved to struts 1.1 
specific MethodUtils.
Get the original method back from the back up java file. Cut and paste 
getAccessibleMethod()
back into the new file. Change the lines to revert back to

return (  getAccessibleMethod(descriptor.getReadMethod()) );

return (  getAccessibleMethod(descriptor.getWriteMethod()) );

Recompile Struts 1.0.2 using Ant
Should work now

Hi

I would like to introduce mapped bean properties into Struts 1.0.

I can copy the source code from commons/bean-utils 1.2
PropertyUtils.java and BeanUtils.java and
the new MappedPropertyDescriptior.java back to the Struts 1.0
source base. This is the simple part, but ...

Is there anything else I need to be aware of?

Re: NeXt question

[Arron Bates]

The real answer is... whatever makes a valid Struts form bean.

What I like is that only the top bean has restrictions. Every other 
level down doens't care in the slightest.

Forcing a form-reload OR a select Options reload

[theron . kousek]

Is  there a way to cause an html select control to "reload from a different
collection" -OR- to "update the collection and have the html select be
refreshed"?

If I have:

 

Can I automatically repopulate the psindustrytype collection if the user
clicks on a checkbox on the form?Is there a way to do this without
having to resubmit the form? I am guessing not

Another approach would be to have a javascript function (that gets called
when the user clicks on a checkbox) call an Action.   Is the best way to do
that in Javascript use use the "self.location=WhateverActionToCall"

RE: DHTML Menus and Form Objects

[Matt Raible]

I've used the following javascript function to hide selects and checkboxes. 
I've tested it with "standards-compliant" browsers
(http://archive.webstandards.org/upgrade) and it works great.

/* Function to hide form elements that show through
   the search form when it is visible */
function toggleForm(frmObj, iState) // 1 visible, 0 hidden 
{
for(var i = 0; i < frmObj.length; i++) {
if (frmObj.elements[i].type.indexOf("select") == 0 ||
frmObj.elements[i].type.indexOf("checkbox") == 0) {
frmObj.elements[i].style.visibility = iState ? "visible" :
"hidden";
}
} 
}

Hope this helps,

Matt

RE: Multiple submit buttons solution

[Maturo, Larry]

We have a different solution to this problem.
One of the guys I work with thought of it. It
seems to work pretty well.

We have a subclass of Action and a subclass of 
ActionFrom, that together implement the if then 
else test.  We actually convert to integer and 
use the following switch statement:
switch (myForm.getCommandType()){
case SUBMIT_TYPE: 
errors = doSubmit(mapping, myForm, request, response);
forward = mapping.findForward("submit");
break;
  case SAVE_TYPE:
errors = doSave(mapping, myForm, request, response);
forward = mapping.findForward("save"); 
break;
  case PROCEED_TYPE:
errors = doProceed(mapping, myForm, request, response);
forward = mapping.findForward("proceed");  
break;
  case CANCEL_TYPE:
errors = doCancel(mapping, myForm, request, response);
forward = mapping.findForward("cancel");
break;
  case ADD_TYPE:
errors = doAdd(mapping, myForm, request, response);
forward = mapping.findForward("add");  
break;
  case DELETE_TYPE:
errors = doDelete(mapping, myForm, request, response);
forward = mapping.findForward("delete");
break;
  case EDIT_TYPE:
errors = doEdit(mapping, myForm, request, response);
forward = mapping.findForward("edit");
break;
  default:
errors = doDefault(mapping, myForm, request, response);
forward = new ActionForward(mapping.getInput());
}

The routines called are defined like this:
protected ActionErrors doDefault(ActionMapping mapping, 
 AgActionForm form, 
 HttpServletRequest request, 
 HttpServletResponse response)
{
return null;
}

and then in the the action classes we derive from this, we just have to
override the appropriate routine.  It puts all the code in one file,
which isn't perfect, but gets rid of the if then else ugliness in the
code.

Subject: Re: Multiple submit buttons solution
From: "Pim" <[EMAIL PROTECTED]>

Ok,

What I want is using multiple actionforms. The reason for this is because I
want to use different validations. I want no validation for create, I want a
validation for Save and I want a validation for say, fetch.Validations for
save and fetch are different.

What I don't want is one actionform with an if -then -else statement saying
if create, then do this, if save then do that. I want to have one superclass
with the properties of the jsp and the subclasses for different
actions(create, save, fetch).

So what we figured out was different mappings for the different actions
(create, save, fetch). The problem however is that the  can only contain one action of course. Our solution to that is
with the help of javascript we change the action.
For example if I press the fetch button, the action becomes one like this:


So, does this makes sense? Are we on the right track or are we missing
something?

Pim

RE: Poolman is gone, I hardly knew ya

[Adriano Labate]

Yes I agree too, Ted.  Poolman is an excellent, highly configuable, product.


I only regret that it lacks one final feature that other connection pools
already have, the pooling of prepared statements. 
It was one of the new features of the last 2.1beta version but it seems that
it was too buggy and a lot of people (including myself) had to go back 2.04.

I've proposed the author to donate its project to Jakarta hoping that it
could continue to evolve but I had received no answer so far.

Excellent point Ted.  And poolman has features you won't find in many of the
other connection pools currently available.

Despite it no longer being supported, it seems it may still be the best
solution.

Thanks so much for your thoughtful words!

RE: Issue with data sources in mySQL

[Immanuel, Gidado-Yisa]

Juan,

I recently put in a mysql JDBC driver.  What I've noticed is
that when the controller (ActionServlet) initializes, it tries
to initialize the DataSource (using the associated connection
pool?).  If there is a problem with initialization, the
ActionServlet init fails.  The error that led to failure in all
my uses, was having the username and password set incorrectly.

Look in the logs for the exact error message.  For example,
in Tomcat 4.0.1, you would go to ${CATALINA.HOME}/logs

hope this helps,

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

seems just as clear to me as
> > 
> > d:/repository
> > assets
> > file://d:/repository/assets
> > 
etc.

Cons of xml
- Carefull with that ",<,> sign eugene,
- Slow parsing

Re: Logging & Log4J in 1.1

[David Winterfeldt]

Log4J recently added some new classes.  I would check
that you have a version of Log4J and Commons Logging
from the same time.  I had some trouble too until I
went and downloaded the latest version of each.

RE: "Best Practice" for parsing an XML file for application confi guration parameters?

[Hoang, Hai]

Nothing is wrong with the properties file...Xml is just better

1.  one config.xml file in one central place...it's so much easier to manage
then a whole bunch of properties
2.  xml handle the structure data much better then properties file

how to edit an array of records with action forms?

[Ian Tomey]

Hi all,

Got an array of records and I want to put them onto the screen to edit. What is the 
technique to go about this? (i am using the nightly 1.1 at the moment)

is it create an action form that maps a single record and create a load of them? or 
create an action form with the properties being arrays of the information?

one form in total or one form per record?

i take it the indexed= attribute for the html tags is going to be useful?

It's not obvious how to do this and I just dont have time to expriement (deadline to 
meet). Any help appreciated

Cheers
Ian

bean:write and XSLT Coldjava taglib

[Rajagopal V]

Hi all
Im using the Coldjava Taglib for XSLT Operations and
the input that  I feed to it is a request scope
variable.


 


I have a request scope variable called xmlString which
contains a Stringified version of my DOM. When I do
this, it throws me a "Markup in the document preceding
the root element is not well-formed". My XML is 
perfect. because if i use it this way



 <%= pageContext.findAttribute("xmlString") %>


It works fine this way. Why isnt the first one
working??

TIA

I have used jdom and really like it. It's not blindingly fast, but it
saves me enough time that I don't mind.

I think the settings should all be contained in a bean.

You will need xerces.jar as well as jdom.jar.

For mini applications then common digester is worth considering.

Oh yes www.jdom.org

(2) Yes or make it accessible as static property of the StartupServlet.

Subject:"Best Practice" for parsing an XML file for application configuration 
parameters?

I am developing an application that will require different application settings
for different machines/customers.

Because of this, I want to to externalize certain configuration settings to a
XML file outside of web.xml - let's call this myApp.xml.

I have a StartupServlet that I can parse this file with.

1.  What should I use to parse this file - SAX, DOM, Digester?

2.  Should I have a bean that represents all the configuration settings, and
put this in the ServletContext as an attirubute, or each individual setting?

If you have one of those DHTML/JS pulldown menus, it'll get hidden behind
specific types of form objects (mostly select boxes).  I've scoured google
to see how to get around this and the only posts I've seen (that don't say
"you're SOL" - which is most of them) that have any constructive input say
to surround the form object w/ a div tag and to set the z-index property to
something very low, then to set your DHTML/JS menu to something very high.
The idea being that the form objects are assigned a lower z index than the
menu so the menu should display over all the form object elements.

Excellent point Ted.  And poolman has features you won't find in many of the

Despite it no longer being supported, it seems it may still be the best

I guess that this is what handles the "conversion" of a getProperty method

So the get methods to relate beans should be handled in similar fashion?

That's great if it's the case.  I will assemble a test of Simper-NeXt today
and see if it works.  Amazing that everything fits together like this! I

Subject: RE: simper-NeXt


Simper's representation of a database row is in the class SimperBean.
SimperBean is a relatively shallow extension of the DynaBean (actually
DynaBean is an interface -- BasicDynaBean is a concrete class which
SimperBean extends) -- see the commons project "BeanUtils" for the
source to DynaBean.

Table columns, as well as relations, are represented as dynamic
properties using the DynaBean/DynaClass mechanisms. It does NOT produce
"get" and "set" methods for each column or relation. Instead, there is a
single "get" method and a single "set" method, whose first parameter is
the property name. This isn't a Simper convention, it's a DynaBean
convention.

DynaBeans/DynaClasses are supported by the latest (nightly builds) of
the other "beanutils" classes, which is why the Struts tags like
, , etc., all work with SimperBeans (and why
I chose DynaBeans as a basis).

With all that said, I really don't know much about the new Nesting tags
or how they work. If they rely upon the same introspection mechanisms as
, , etc., then they should work with Simper
just fine. That's just a guess.

This is what was unclear to me.  I guess when you create relations
between
tables in Simper these get Methods to return another bean will be
created in
the SimperBean automatically?

Almost.
NeXt is only working off of Bean properties, and as with all beans, it
doesn't care as to what goes on behind those method definitions. The
constructor is one of those details it cares not about.

So as long as the simper beans have bean property conformity (eg:
getMyProperty, setMyProperty) then the beans are ready to go with NeXt
as they are wihout mods. I'd be very surprised if it needed mods,
really. You can use Castor types straight up because the properties are
valid bean properties.

A nested bean is simply one object that is returned by the method of
another. As each property getter method has "get" on the front of it,
we're laughin'. At the point of changing a property, you'll need that
"set" on the front of it, naturally. For example, to get the nesting
level deeper in my Monkey examples, I had a "fake" nested property that
returned "this".

eg:
public MonkeyBean getOtherMonkey() { return this; }

To the internals of BeanUtils (the part of Struts that makes it all
happen), it's treated as an entirely different object. It makes no other
assumptions, rightly so. The system is that explicit.

Just give it a bash. Run a simper model through the NeXt tags. I lay my
money on it working as-is.

Arron.

RE: DHTML Menus and Form Objects

[Galbreath, Mark]

It's the opposite, John.  The lower the z-index, the more foreground
preference the object has.  I like the "SOL" idiom, too.  :-)

If you have one of those DHTML/JS pulldown menus, it'll get hidden behind
specific types of form objects (mostly select boxes).  I've scoured google
to see how to get around this and the only posts I've seen (that don't say
"you're SOL" - which is most of them) that have any constructive input say
to surround the form object w/ a div tag and to set the z-index property to
something very low, then to set your DHTML/JS menu to something very high.
The idea being that the form objects are assigned a lower z index than the
menu so the menu should display over all the form object elements.

RE: DHTML Menus and Form Objects

[Assenza, Chris]

To the best of my knowledge there is no workaround, it's a "feature" of
today's browsers. No amount of finagling z-indexes is going to help.  

A viable option that Microsoft implemented was to hide (as in hide the
layer) the select boxes whenever a menu came in contact with one, then to
unhide it when the menu was gone.  It's a little more trouble then it is
worth to implement and not the most reliable of solutions.

Just another reason not to use drop-downs on a web page actually. 
This stupid bug has been a thorn in my side before. :\  Shame really,
drop-downs nice for application development. 

Here's a link to one guys experience with this back in IE4 days.

"Best Practice" for parsing an XML file for application configuration parameters?

[Matt Raible]

I am developing an application that will require different application settings
for different machines/customers.

Because of this, I want to to externalize certain configuration settings to a
XML file outside of web.xml - let's call this myApp.xml.

I have a StartupServlet that I can parse this file with.

1.  What should I use to parse this file - SAX, DOM, Digester?

2.  Should I have a bean that represents all the configuration settings, and
put this in the ServletContext as an attirubute, or each individual setting?

3.  If I use Digester and a bean (seems good), should I change my XML in the
following snippet?



d:/repository
assets
file://d:/repository/assets



75



Any help (or URLs) are appreciated!

Matt

RE: DHTML Menus and Form Objects

[ltorrence]

I think the layer thing works in very new versions of IE (newer than IE5 --
maybe starting with 5.5?). Back when I was looking at such things, the only
solution I could find for IE 5 was to hide the offending form elements when
the show menu function is fired. Kind of clunky, but that's exactly what
Microsoft used to do on their site.

Netscape/Mozilla is another story altogether.

Tiles question: Using inside tiles:put

[Molitor, Stephen]

Is it OK to use bean:message to look up a message inside a tiles:put tag?
For example:

  

  

The instantiating page might get the title like this:

  

Is anyone else doing this?  Usually this works for me, but sometimes the
servlet container (WebLogic SP8) blows up on the getAsString.

Thanks!
