How do you update the database with last user logon information?

[Alex Paransky]

I seem to have a small problem.  It's quite simple.  All I want to do is
update the database when a user logs on.  However, with the Servlet
authentication mechanism, there does not appear to be a way to execute a
process or a method after user is authenticated.

I am just wondering if Struts or other libraries have somehow implemented
something that can help me in this area.  Or how do other people do this?

Thanks.

Well, you can specify the "style", "id", and "class" attributes with these

Tiles question: Is it possible to insert a ComponentDefinition into a Tile context dynamically?

[@Basebeans.com]

Subject: Tiles question: Is it possible to insert a ComponentDefinition into a Tile 
context dynamically?
From: "Chris Cool" <[EMAIL PROTECTED]>
 ===
Hi,

I have a tile that reads items from a PutList list and then inserts each
item into the current page.







When the items in the list are tiles defined in my tileDefinitions.xml file,
the tiles are inserted into my JSP correctly. However, I want to dynamically
create a tile definition and insert it into the page context.

I am generating the ComponentDefinition in my tile controller and accessing
the "itemList" where I add the name of the dynamically generated definition:

/* get the item list and insert new tile def into it */

ArrayList itemList = (ArrayList)context.getAttribute("itemList");

if (itemList != null) {

HashMap map = new HashMap();

map.put("name", "newtarget");

map.put("link", "newtarget.do");


ComponentDefinition newItem =

new ComponentDefinition("new.item",

"/mytiles/simpleItem.jsp",

map);

DefinitionsUtil.setActionDefinition( request, breadCrumbItem );

itemList.add("new.item");

}

In my tile, the "itemList" contains the "new.item" entry, but it does not
appear to find the ComponentDefinition I created.

Thanks for you help.

Chris

Re: what is html:link equivelant

[Eddie Bush]

Well, inside of your CSS, you make definitions for styles, correct?

If you begin a definition name with #, as in:

#myStyle { text-decoration: none }

then the 'name' (myStyle) is known as an 'Id'.  Therefore, if you wanted to
use this definition with a link, you would specify styleId='myStyle' in your
 tag.

Similarly, if you define a style as:

.myStyle { text-decoration: none }

then the name (myStyle again) is known as a class.  Therefore, if you wanted
to use this definition with a link, you would specify styleClass='myStyle'
in your  tag.

And, last but not least, there is the style attribute of the link tag.  This
is where you could hard-code a style for a given link (ie. not place it in
the css file but directly in the code).  By specifying
style='text-decoration: none' as an attribute to your link tag, you would
accomplish the same thing as the above two methods, but without the CSS
file.

HTH,

Eddie

As far as I can see your code looks Ok.

Okay, so now I have the following:

and I have an int[] field on my bean called "assetId"

and it's telling me 

"You must specify the value attribute or nested tag content"

I thought that's what I was doing when I specified
value="<%=sb.getCheckBoxName()%>" in the multiBox.

the getcheckboxName, by the way, returns the assetId, so I hope to end
upwith an array of these things in the bean

Look at the multibox tag.  Add an attribute to your form called product (I
think it has to be an a String array) and when you read.  It will populate
the array with the product selected.

Subject:  Form Question - Dynamic number of checkboxes



Hi there all

I'm generating a form that can have dynamic checkboxes depending on
information retrieved from my database. I basically retrieve a bunch or rows
and for each one, I want to create a checkbox.

Than, in the Action class handling the form submission, I plan to loop
through the checkboxes, and build an array of those that were selected, and
do something to them.

The problem is that I am tying to name the checkboxes for the ID of the
row... here is a JSP snippet:


  
<%=sb.getProductName()%> 
  
  




the getCheckBoxName() comes from the database, and it correcponds to the
"Product" in this row, and it's dynamic.

Struts complains with the following error message

 No getter method for property 4363 of bean
org.apache.struts.taglib.html.BEAN

Essentially, I'm trying to create the following
 and struts can't find get4363() in the
bean. No surprise there, I can't create getters for all the possibilities. I
just planned to loop through the submitted form fields to get the ids
checked.

Is there any way that Struts can not care that the setters don't exist?

Does this make sense?

what is html:link equivelant

[theron . kousek]

This is tricker than I thought:

What is the equivelant of:

http://localhost:8080/express/billing.css"; rel="stylesheet">

using the html:link tag?

I see they have the style property and the styleClass property but I am not
sure exactly how they are used.

thanks for any insight...

RE [2]: Form Question - Dynamic number of checkboxes - Multibox ?

[Mattos, John]

Okay, so now I have the following:


  

<%=sb.getProductName()%> 
 
 


 
   


and I have an int[] field on my bean called "assetId"

and it's telling me 

"You must specify the value attribute or nested tag content"

I thought that's what I was doing when I specified
value="<%=sb.getCheckBoxName()%>" in the multiBox.

the getcheckboxName, by the way, returns the assetId, so I hope to end
upwith an array of these things in the bean

Look at the multibox tag.  Add an attribute to your form called product (I
think it has to be an a String array) and when you read.  It will populate
the array with the product selected.

Hi there all

I'm generating a form that can have dynamic checkboxes depending on
information retrieved from my database. I basically retrieve a bunch or rows
and for each one, I want to create a checkbox.

Than, in the Action class handling the form submission, I plan to loop
through the checkboxes, and build an array of those that were selected, and
do something to them.

The problem is that I am tying to name the checkboxes for the ID of the
row... here is a JSP snippet:

the getCheckBoxName() comes from the database, and it correcponds to the
"Product" in this row, and it's dynamic.

Struts complains with the following error message

 No getter method for property 4363 of bean
org.apache.struts.taglib.html.BEAN

Essentially, I'm trying to create the following
 and struts can't find get4363() in the
bean. No surprise there, I can't create getters for all the possibilities. I
just planned to loop through the submitted form fields to get the ids
checked.

Is there any way that Struts can not care that the setters don't exist?

Does this make sense?

If you have a form nested like this, it probably
doesn't have the servlet reference set on it.

ServletContext application =
getServlet().getServletContext();

Otherwise what you are doing should be fine.

We're converting our existing JFC/Swing application to use struts.We
have 3 developer's and have written alot of jsp's.   Our pages look quite a
bit different and it's time to start converging them to use a uniform
front-end look and feel.

Can others offer opinions as to how you're doing your front-end's?

- Are you using html generator's?If so, which are the best one's
- Or are you hand-typing in your html within your jsp's and using the
taglibs?

Currently, we're doing the latter and are checking into what
tiles/templates can offer but I was wondering how others are doing it?

Re: [Re: how to dynamically change form in a tag]

[Jay sissom]

The  tag and the <%= ... %> tags are server tags.  They get 
compiled into Java code that compiles on the server.  From what I've 
discovered, you can't nest these tags.  I'm sure someone will correct me 
if I'm wrong.  I have found that you can nest server tags within browser 
tags like this:



In tomcat, when a JSP is run, the compiled version and source code is put 
into a work directory.  When I run tomcat under jbuilder, the work 
directory is within my project.  If you find the source code for your 
example below, you'll see that the value "<%= request.getParameter... %>" 
is being put in the action property, not the evaluated version.

Again, this is from my poking around on tomcat.  I haven't read the 
servlet spec about this so I don't know for sure that this happens on all 
servlet containers.

To boil it all down, you can't nest server compiled tags.  That's why your 
solution doesn't work.

Validating an ActionForm "conditionnally"

[Sobkowski, Andrej]

Hello,

I've been using the Struts Validator (nightly build of November) with no
problems for a few months (great work!).

Now I need to call the validation method of a specific "nested form" based
on a condition:

ParentForm
+useChild: boolean
+getChildForm:ChildForm

If useChild returns true, I want to call the validate(mapping, request) of
ChildForm (ie the nested form).

I thought that the validator only needed the "mapping.getAttribute()" (name
of the ActionForm) to perform the validation so I tried with the following
(ugly, I know):

if (parentForm.useChild()) {
ActionMapping newMap = new ActionMapping();
newMap.setAttribute("childForm"); 
ActionErrors errors = parentForm.getChildForm().validate(newMap,
request);
}

The configuration is extremely basic:
- In struts-config.xml:

- In validation.xml:
  
...
  

I'm getting a NullPointerException in the validator's code.

What am I doing wrong? Is this a good way to handle the problem (I doubt
it...)? Any suggestions?

Thanks.

Andrej

RE: [Newbie] prob with or tag

[Slimane Zouggari]

Hi,

thanks for your answer :)
Unfortunately, it still doesn't work the way I want it to. However I do 
have a more explicit error-message (see below).

So, when I do the following, it doesn't work:

1/
   
 Sélectionnez le type de requête
   
 
   
   

But when I do the following (however, I'm aware it's not the Struts way), 
it suddenly works:
2/
   
  Sélectionnez le type de requête
 
   
 ">
   
 
   

What am I missing ? :(

Friendly Regards,
Slimane

RE: How to compare a notNull string with the nullString!

[Jennings, Christofer J.]

I came across this yesterday. Here's what I found. If a bean exists with a
null field, doing a logic:present on the field return true and comparing it
(e.g., using logic:equals) gets a NullPointerException.

If there is a custom tag to check for null values I'd love to know it.

I think this may be what Pitbull is after too, yes? Or do you really want to
campare with an empty string ""?

PropertyUtils and NoClassDefFoundError WLS6.1, struts 1.0

[Jouanny]

Hello

I'm working on Weblogic 6.1 using Struts 1.0.

I'm making use of the method getPropertyDescriptor(Object object, String 
name_of_Field) of  the org/apache/struts/util/PropertyUtils class in order 
to get a java.beans.PropertyDescriptor.

This PropertyDescriptor is used in a class which implements Interface 
java.util.Comparator in order to sort a  java.util.ArrayList with 
Collections.sort(List aList, Comparator aComparator);

I get what is folowing :

Servlet failed with Exception
java.lang.NoClassDefFoundError: org/apache/struts/util/PropertyUtils

struts.jar, which contains the org/apache/struts/util/PropertyUtils class, 
is in Web-inf/lib.

Make sure that you use the  taglib. Currently you are not
using it. It will get the bean for your page...

Hi,

I have a weird problem here (as always :).

I have the following code in my *.jsp file:
   
 Select request type
   
 
   
   

so,
 codtyp  is a property of
HandleProjectAddRequestAction
 projectaddrequestform   is a session bean (it's actually loaded

into the session, because I did the check before in the jsp page)
 listTyp is a collection (ArrayList) of 
beans (type is one of mine named ElementSimple)
 id and name are two properties of the class
ElementSimple

My session bean is well loaded.
My ArrayList does contain values.

So why do I have an error when I try to execute the preceding code ?

Thanks for having read me so far :)

Friendly Regards,
Slimane

[ANN] New ActionForm-to-Value Object (and back) mapper

[Sobkowski, Andrej]

Hello,

the new version of the Form-to-VO and VO-to-Form mapper is now available at 

http://www.mycgiserver.com/~andrej/technical/struts/struts.jsp

It allows you to perform in ONE line of code the mapping between

ExampleForm 
+getLastName:String
+setLastName(String)
+getDateOfBirth:String
+setDateOfBirth(String)
+getYearsOfJavaExperience:String
+setYearsOfJavaExperience(String)
+getEmailAddresses:String[]
+setEmailAddresses(String[])
+getChild:ChildForm
+setChild(ChildForm)
+getChildren:ChildForm[]
+setChildren(ChildForm[])

and

ExampleVO 
+getLastName:String
+setLastName(String)
+getDateOfBirth:Date
+setDateOfBirth(Date)
+getYearsOfJavaExperience:Integer
+setYearsOfJavaExperience(Integer)
+getEmailAddresses:String[]
+setEmailAddresses(String[])
+getChild:ChildVO
+setChild(ChildVO) 
+getChildren:ChildVO[]
+setChildren(ChildVO[])

by simply writing FormToVOMapper.map(exampleForm, new ExampleVO()) or
VOToFormMapper.map(exampleVO, new ExampleForm()).

New features/bug fixes:
- Date format is now configurable via System properties
- fixed support for nested elements
- added support for Boolean (any new type can be added in less than 2
minutes)

Future enhancements:
- support for primitive types
- support for nested Collections

Documentation is extensive both on the HTML page and in the code. JUnit
tests are provided with the distribution.

It's still a "0.9beta" release because I wanted to get the enhancements in
before the 1.0 but the code has been running with no problems in our project
for 4 months now.

Any feedback is appreciated :)

Andrej

Re: Newbie Question - Please Helpme (Cannot find ActionMapping or...)

[Anant Sagar]

This usually happens due to improper setting of  Data Source Configuration
(  ) in struts-config.xml file.
Check whether driverClass ,url,user,password entered are correctly .
Hope that may help you.

Re: Application without cookies and sessions

[Ted Husted]

The intent of the Struts Example is not to demonstrate best practices,
but to demonstrate how to do several things that developers commonly
want to do. One thing that many developers like to do is store objects
in the session context, and so the example demonstrates how this can be
done. Of course, there are many ways to do most anything, and Struts is
designed so that it can support just about any scheme you choose.

Re: Web application with my own authentication process

[Ted Husted]

Typically, people will place an object in the session that indicates
that the user is logged in. You can then either subclass the
ActionServlet to check each incoming request for that session object. If
it is absent, you redirect them to a logon page. More often, people
create a base Action that does the same thing. This makes it easier to
have authenticated and unauthenticated requestd, depending on whether
they extend the authenticated Action or not. The simplest thing is to
have create your own doPerform(...) method, and have the developers
extend that instead of process. Perform then calls doPerform

perform
// Obtain logon
Bean account = request.getSession().getAttribute(LOGON_KEY);
if (account==null)
return mapping.findForward(LOGON_FORWARD);
return doPerform( ...


Also, please do not cross-post questions like this to the DEV list.

Re: Tiles & sub-applications?

[Ian Tomey]

ok, cheers Cedric.

Please make sure that sub applications can access master definitions/actions as well, 
as sub applications accessing say a page definition in the root/default app would be 
very useful.

I have put an enhancement request in for 1.1 b1 to modify the html:form and html:link 
tags to check for a "//sub_app_name/actionorpage" (just a proposal) type format to 
access actions/pages outside the current sub application. Something along these lines 
in tiles would be very useful, as the main look and feel of the app could be defined 
by the default app, with the sub apps inheriting the page layout without having to 
duplicate the definition in each sub app.

cheers
ian



>>> [EMAIL PROTECTED] 03/22/02 09:26am >>>

  Hello,

  Tiles doesn't support sub applications yet, as defined in struts1.1.
  Actually, there is only one definition factory for all sub application. However, it 
is already possible to have several definitions files, but definitions should have 
different names.

  I will provide sub application support, as well as struts plugin asap (hope in less 
than 2 weeks)

HOWTO: Lessons learned from using Struts, Tomcat and Oracle

[Ted Husted]

 Original Message 
Subject: Lessons learned from using Struts, Tomcat and Oracle
Date: Thu, 21 Mar 2002 19:43:22 -0800 (PST)
From: "Walter S. So" <[EMAIL PROTECTED]>

Hi Ted,

I just want to share this information in case someone else also
goes through the same problems I did.  I was able to come up
with this solution after spending an entire afternoon searching
through the net and archives, so if it saves people a few hours
of debugging, I'll be happy.  I am not sure how to categorize it
or even which mailing list to send this, whether it should go to
Tomcat, Struts, or Tyrex, so I decided to send it to you since
you are active in Jakarta.

My goal was to set up a Connection Pooled DataSource using
Oracle running Struts on Tomcat.  I use Tomcat 4.0.3, Struts
1.1-b1-lib, Oracle 8.1.7 "classes12.zip" running on Windows 98,
but it should work well on Solaris/Linux.

Initially, I set up the Oracle JDBC drivers under my webapp and
used the  in struts-config.xml to access Oracle.  My
application consistently hung after the pool was exhausted. 
(For example, if I set the minCount and maxCount to "10", my
webapp would hang after 10 requests)  The problem of Oracle
connections not being returned properly by the Struts pool was
well documented in the mailing list, so I switched the
datasource from struts-config.xml to tomcat's server.xml.  I
followed the instructions in the Tomcat jndi-resources-howto and
copied the Oracle drivers to common/lib after renaming the
"classes12.zip" to "classes12.jar" as suggested by the mailing
list.

I found my webapp wasn't running properly as the servlet would
stop executing after context.lookup().  This bothered me because
Tomcat was not throwing any exceptions. After some more
research, I changed the debug level in server.xml from "0" to
"99".  This time, the log generated showed a
java.lang.ClassCastException: tyrex.jdbc.xa.EnabledDataSource
when the lookup() is called.  A post in the tomcat-dev mailing
list provided the answer:  There was a conflict in the jars of
tomcat and the webapp.  True enough, I found a
jdbc2_0-stdext.jar (83KB) that came in tomcat\common\lib, and a
jdbc2_0-stdext.jar (7KB) that i had unpacked from Struts to my
web-app.  After deleting the 7KB jar, the lookup() executed
properly.

To sum up, when using a DataSource in Tomcat and Struts in the
webapp, make sure to remove the extraneous jdbc2_0-stdext.jar
that comes with the Struts Lib. :)

Hope that helps,

Walter

Re: Keep a session in different war

[Ted Husted]

It's not permitted. Each web application has its own session for
security reasons. The options are 

* URI's
* Cookies,
* Or a shared database

One popular approach is to use cookies to create a common autologin
procedure that the applications share. Tomcat supports this, and I
believe Expresso is floating a proposal regarding a common convention we
call can use.

Re: Detect stop in Action

[Ted Husted]

The Action is a servlet-delegate, and so anythinng you can detect in a
servlet you can detect in an Action. You might ask about detecting stop
in a servlet on jGuru or The ServerSide (and report back :o).

If you are using Ant, the best thing is to have it add the struts.jar in
your webapps lib to the patch.

Struts is designed to use its own ActionServlet. You instead write
Action classes to do what is usually done in standalone servlets. The
Actions are servlet-delegates. The servlet calls the perform method on
each Action, and passes it the bean specified in the struts
configuration. 

A re-reading of the Struts User Guide from the beginning might help
bring things into focus for you. Be sure to review the list of
pre-requesite materials at the top of the introduction.

Re: Application without cookies and sessions

[Nicolas De Loof]

You can configure the session time-out on your servlet container. (refer to
it's documentation). I currently use 30 minutes for web administration
application.

When the time-out occurs, the session collection and it's included objects
are destroyed.

If you configure a very high time-out, be carreful that the memory used by
the session has to be released when the user quits, using a Disconnect URL
that invalidates the session (see javax.servlet.http.HTTPSession javadoc).

There is a mecanism to make the session being persistant: The session
objects and ID are store to a database. This is called "persistant session
management". I've never used it, but perhaps you're interested ?

WAS 401/OS390 Deployment Problems - Servlet/JSPs not found

[Andre Kreich]

Hi there,

we've got a problem Deploying Struts on WebSphere 401 running on OS390. The
ActionServlet seems to be initialized correctly, though it parses the
struts-config.xml and calls actionMapping().

The Problem is, that we can access neither servlets nor JSPs, but simple
HTML-Pages. Attached is an extract from the server-log and the DDs.

TIA, Andre Kreich

Hi Nicolas,

First of all, thank you very much for your response.

What about the session timeout??? I don't like websites that if you left it

Is there any way to do a site without take care of session timeouts??

Re: 1 tile <-> 1 controller

[Cedric Dumoulin]

  Hello,

  Tiles support controller for each individual Tile.
  This controller's role is to prepare data to be rendered by the tile.
  Syntax is as follow :

 
  ..
  or

 

  You can find an example of use in tiles-doc.war or struts-tiles.war :

   *   /examples/rssChannels.jsp
   *   / test/testController.jsp

  More documentation is needed ;-(

Re: Tiles & sub-applications?

[Cedric Dumoulin]

  Hello,

  Tiles doesn't support sub applications yet, as defined in struts1.1.
  Actually, there is only one definition factory for all sub application. However, it 
is already possible to have several definitions files, but definitions should have 
different names.

  I will provide sub application support, as well as struts plugin asap (hope in less 
than 2 weeks)

Re: How to display a static file in a body tile

[Cedric Dumoulin]

  You can use Struts  inside your body.
  If you want to use a value coming from a Tile attribute, do something like :

  
  

  Checks documentation for these tags for more :
http://jakarta.apache.org/struts/userGuide/struts-bean.html#include
http://www.lifl.fr/~dumoulin/tiles/doc/tilesTags.html#useAttribute

   Hope this help,

[Newbie] prob with or tag

[Slimane Zouggari]

Hi,

I have a weird problem here (as always :).

I have the following code in my *.jsp file:
   
 Select request type
   
 
   
   

so,
 codtyp  is a property of HandleProjectAddRequestAction
 projectaddrequestform   is a session bean (it's actually loaded 
into the session, because I did the check before in the jsp page)
 listTyp is a collection (ArrayList) of 
beans (type is one of mine named ElementSimple)
 id and name are two properties of the class ElementSimple

My session bean is well loaded.
My ArrayList does contain values.

So why do I have an error when I try to execute the preceding code ?

Thanks for having read me so far :)

Friendly Regards,
Slimane

Problem with logic:equal and logic:notEqual tags both evaluating to true

[$B%"%s%H%K!<(B $B%9%F%$%9(B]

Hi

I have the following code



I am logic:equal


I am logic:notEqual



For some reason it is printing out both

"I am logic:notEqual"

and

"I am logic:equal"

Am I missing the point about the "logic:equal" and "logic:notEqual" tags, or
is there a reason this might be happening?




Cheers

Tony

Re: Application without cookies and sessions

[Nicolas De Loof]

Don't panic about session and cookies !

Session are used to maintain state in your application between 2 request
from user : HTTP is a non connected protocol, so you cannot know where your
user comes from where you perform a request.

Session is just a Collection of objects in memory associated whith an id
that servlet container maintain for you. User browser whith cookies
activated receives a cookie with this id so that the container is able to
link future request to the session collection associated with the user.
Without cookies, URL are expanded to add the id as a parameter of requests.

If you put objets in the request scope, after the JSP has produced the HTML
page the objects are destroyed ! Your user objet that MUST be retrieved in
other requests MUST be in the stored session scope.
