it's in WEB-INF/classes called ApplicationResources.properties it works when I use bean:message key=prompt.login/ so I know it's loaded ok it also works when I call the deprecated getResources()... just when I add the request param or the request and key param I get null but getResources is deprecated so I don't want to use that!

Re: [Tiles] Conditional menu items. Help !!!!
Hello, There is several solutions to have different menu for different users or profile. You need to have some logic that select or build the menu according to the current user profile. Solution 1: * Create an action with one forward for each possible menu. The action checks the user profile, and call forward to appropriate menu. * Create one tiles definition for each possible menu * Associate forwards to definitions * Call the action each time you need to render the menu Solution 2: * Create one action that build dynamically the menu definition to be rendered * Action push the definition in request session (see examples in tiles-doc/test) * Action do its forward, which will use the pushed definition Solution 3: * Associate a controller to your menu definition * This controller build/modify the list of menu item Hope this help, Cedric LFung wrote: Hi.

Re: What mechanisms do Tiles use for layout
In the tiles examples, there is several layouts: some use tables, other use div. As David says, Tiles doesn't care about your layout. You can reuse existing layouts, or define your own as you want. The layout is just a jsp page containing insert tag where you want to insert sub-tiles. You can use any html or jsp tags to arrange your layout.

Setting the input from within the ActionForm in Struts 1.1 no longer allowed?
Hi Using 1.0 I had a situation where I used to dynamically set the input from within my ActionForm. In 1.1 (b2) this is no longer possible, since the configuration of the object is frozen. An IllegalStateException is thrown and my app no longer works as required. What is the suggested way to get around this? Should I reconfigure my app so I don't dynamically set the input, or is there another way in Struts 1.1 to dynamically set the input? TIA, Karim

threading question
Hello,
Quick Struts/servlet threading question: If many classes extended the
following 'AbstractAction' class (eg, 'ConcreteAction'), would use of the
'testString' member variable be threadsafe?
public abstract class AbstractAction extends Action{
protected String testString;
public ActionForward perform(
ActionMapping map,ActionForm form,HttpServletRequest
req,HttpServletResponse res){
testString = req.getParameter(myParam);
// other common processing
return process(map,form,req,res);
}
public abstract ActionForward process(
ActionMapping map,ActionForm form,HttpServletRequest
req,HttpServletResponse res);
}
public class ConcreteAction extends AbstractAction{
public ActionForward process(
ActionMapping map,ActionForm form,HttpServletRequest
req,HttpServletResponse res){
// do something with testString...
// return an ActionForward object...
}
}
I was strictly thinking of using the protected members on a per-request
basis, always initializing them in the AbstractAction's perform() method.
Furthermore, if use of testString is OK, wouldn't it be OK to have a member
vars of type HttpRequest, etc. and set it/them in AbstractAction's
perform(), thereby avoiding all the associated parameter passing?
Using Struts 1.0.2 if that makes any difference.

RE: Populate form with ActionForm
Put a action in the middle. The action puts the bean in the request of the second jsp. If the second jsp populates a form with this bean, you can pass the actionform to the request instead of the bean and struts will populate the form for you. The only requisite is that the action associated with the form uses the actionform that you put in the request.

Re: threading question
Of course, if you have several objects of ConcreteAction, every object has
its own testString. So if each object has only one thread attached to it,
the access to testString is thread-safe.
You could put a counter to see how many ConcreteAction objects there are:
class ConcreteAction
{
static int counter = 0;
{
++counter;
System.out.println( + counter );
}

public ActionForward process(
ActionMapping map,ActionForm form,HttpServletRequest
req,HttpServletResponse res){

I was strictly thinking of using the protected members on a per-request
basis, always initializing them in the AbstractAction's perform() method.
Furthermore, if use of testString is OK, wouldn't it be OK to have a member
vars of type HttpRequest, etc. and set it/them in AbstractAction's
perform(), thereby avoiding all the associated parameter passing?
Using Struts 1.0.2 if that makes any difference.

RE: Where's the form-bean???
Hi Jason, Thanks for the reply. You've got it right in what I'm doing. However I think I could describe the problem more simply. The problem is that when validation fails and I'm forwarded back to the Action specified by the mapping's input attribute, the form that is passed in to Action.perform() is null. I'm puzzled because when the Action then forwards to the .JSP page, all the form values are populated.

I think I understand what you're doing, but feel free to ignore me if not. What I often do is to present availXXX object arrays to the front-end via request/session attributes that the front-end developer knows is meant to be a read-only informational array shared between different actions or action forms as the case may be. These availXXX arrays are typically used to populate selection boxes or to generate lists that are used as entry points into actions on specific items in the availXXX array.

I'm using two select boxes to implement the user selection metaphor where one contains available choices, and the other contains selected choices. If the form does not pass validation, I need to repopulate the selected choices from the array of its values, contained in the form bean. This is done in the action class that sets up all the data for the form. After I submit and validation fails, Struts forwards back to the input url, which is an action class. The problem is that the form object passed into perform() is null, so I can't get the array of values. What has me vexed is that after perform() forwards to the .jsp, all the form elements are populated as they were prior to submit, so the populated form exists, it's just not being passed in to perform(). I tried adding the name=formName attribute to the mapping, but then Struts tries to validate the form on the GET, as shown by the debug log below: -Processing a GET for /standards/curriculum-coverage-form -Looking for ActionForm bean under attribute 'curriculumCoverageReport' -Creating new ActionForm instance of class '...standards.CurriculumCoverageReportForm' -Storing instance under attribute 'curriculumCoverageReport' in scope 'request' -Populating bean properties from this request -Validating input form properties -No input form, but validation returned errors Any insight into this would be greatly appreciated.

Re: Help with Struts + DB Access
Wendy - One approach I've used is: - Create (as it looks like you have) your form bean (that you refer to as the ActionForm extention) so you can set/get the properties using a collection. (eg, setDropdownValues(Collection values), etc.) - In your Action class, have it call what I'll refer to as a 'facade' class that manages retrieving the values. - The 'facade' class should provide a simple method such as facade.getValues() that returns the Collection as you need to set it in the form bean. - The Action class code would look like: formBean.setDropdownValues( facade.getValues() ); This simplifies maintenance of the Action class - not matter what for the values take, the Action class is unaffected. - Then in your facade class, have it coordinate the gathering of the data. It's requirements may be: - perform a getAttribute against the ServletContext to see if the values are stored there already - If the values aren't there, use the DAO to retrieve them - Potentially have it check time of day and periodically refresh the values stored in the servlet context - In addition, have the 'facade' catch any database access exceptions and 'rethrow' them as some sort of Application exception (eg, DropDownException would likely be an awful name, but you get the idea). This ensures that the Action class (the Controller in the MVC architecture of Struts) can manage the exception and redirect processing appropriately. Since the 'facade' hides the database access, the Action class shouldn't be catching JDBC exceptions. This allows you to isolate any changes in business logic or data access down in either the facade or the DAO. The facade simply presents the data in the format that the form bean wants it. I've identified using a Collection to pass values, but it could just as easily be a HashMap or whatever you might need.

DynaActionForm and hashmap property
Hi All, My question is in regard to submitting a JSP form that contains form fields displayed by iterating over a hashmap. I have defined a DynaActionForm in my Struts-config file in which, besides numerous String properties, I have one hashmap. form-bean name=profileform dynamic=true type=org.apache.struts.action.DynaActionForm form-property name= type=java.util.String / form-property name=userFields type=java.util.HashMap / /form-bean Using the profileForm.set() method in my ShowAction for displaying the fields in my JSP form is working fine, including for the hashmap: ShowAction code Fragment: HashMap userFields = new HashMap(); [...builds a dynamic set of user field names and field values...] profileForm.set(userFields, userFields); JSP code fragment: logic:iterate id=userField name=profileform property=userFields tr th align=left bean:write name=userField property=key/ /th td align=left html:text name=userField property=value/ /td /tr /logic:iterate Whereas the theory behind handling the String form fields (dynamic setters and getters) seems very straightforward, I don't understand how the dynamic form handles the hashmap fields (if it is handling them at all?) on submit. How do I access the edited hashmap field values for updating my business objects within the SaveAction? Copying from the successful processing of the form String fields, I have tried in the SaveAction: HashMap userFields = (HashMap)profileForm.get(userFields); but NullPointerExceptions thrown while trying to access 'userFields' lead me to believe that I am not getting my desired results. Any guidance would be greatly appreciated. Thanks, Susan -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Basic Templating Recommendations?

It will map you request url to a definition. Just make sure that everything is happening through struts controller and map you forward to tiles definitions. Have you tried nesting definition in your tiles-def or using the inheritance feature? Basically, I've got a bunch of pages in a site that are static. I need a simple way to template them. I would like to use Tiles, but I don't want to have links to tiles?def=main.index and such. I want links to look like below. So, I'm asking about recommendations to do simple templating of static content, in conjunction with a dynamic site built using Struts. (So I want to reuse the tiles.) Thanks for your help, A. I've tried asking this a few times, but I think I haven't been clear. I need a simple way to have requests converted into calls to Tiles definitions. So, requests like /pages/pageone.thtml, would get turned into a call to the tile pageone. /pages/main/pagetwo.thtml = main.pageone, etc. I thought creating an Action that would figure out the defintion based on the request URI, using the ideas in org.apache.struts.tiles.actions.DefinitionDispatcherAction. However, I've just read that you can't have multiple servlet-mappings. Also, I feel that my approach isn't great.

EL and the developer's roadmap
OK, I'll bite. What does EL stand for? From what I'm hearing, there seems to be a current trend of moving away from Struts taglibs if there is a JSTL tag that has the same functionality. I admit that makes me a bit nervous as a newbie. I'm still learning the struts tags! The Goodwill book has an excellent appendix with _examples_ of individual tag usage. Now I guess I will have to get a book on JSTL book as well. Is there a Struts roadmap available anywhere? Sometimes I feel I am always running to to catch up in Struts. Mastered ActionForms? oops gotta learn DynaActionForms! Learned how to validate in the action class? , ha! better learn Dyna*Valid* stuff. Mastered struts-logic? no! learn JSTL! I know I don't have to use all new features but I would like have a little warning about what may be coming down the road. That is where a roadmap would come in very handy. I could know which technologies to watch and which to ignore in the short term.

Subject: threading question
Hello,
Quick Struts/servlet threading question: If many classes extended the
following 'AbstractAction' class (eg, 'ConcreteAction'), would use of the
'testString' member variable be threadsafe?
As others eventually drank enough coffee to figure out :-), the testString
instance in your example below is *not* threadsafe if you expect to store
per-request state information in it. The general rule is that you can use
*local* variables for this sort of thing (because they get created on the
stack for each thread), but not instance or static variables.
Remember that Struts will create only one instance of each ConcreteAction
for a given action path, so multiple simultaneous requests to the same
Action will share that instance (and therefore the instance variable).
Craig
public abstract class AbstractAction extends Action{
protected String testString;
public ActionForward perform(
ActionMapping map,ActionForm form,HttpServletRequest
req,HttpServletResponse res){
testString = req.getParameter(myParam);
// other common processing
return process(map,form,req,res);
}
public abstract ActionForward process(
ActionMapping map,ActionForm form,HttpServletRequest
req,HttpServletResponse res);
}
public class ConcreteAction extends AbstractAction{
public ActionForward process(
ActionMapping map,ActionForm form,HttpServletRequest
req,HttpServletResponse res){
// do something with testString...
// return an ActionForward object...
}
}
I was strictly thinking of using the protected members on a per-request
basis, always initializing them in the AbstractAction's perform() method.
Furthermore, if use of testString is OK, wouldn't it be OK to have a member
vars of type HttpRequest, etc. and set it/them in AbstractAction's
perform(), thereby avoiding all the associated parameter passing?
Using Struts 1.0.2 if that makes any difference.

something else: org.apache.struts.upload.FormFile
Struts uses a user-configurable implementation of type
org.apache.struts.upload.MultipartRequestHandler as a factory which
produces an implementation of FormFile from the HttpServletRequest.
You rarely have to worry about this detail, but you can set an
alternative MultipartRequestHandler in the controller section of
your struts-config.xml file.
All you really care about is that when you get the ActionForm in your
Action, it has a property of type FormFile.
Hope that helps.

RE: struts-config.xml question
Victor and Emmanuel, thanks for your answers. With them, and the later discussion on similar topics I think I understand. Part of my confusion comes from a bug I've not been able to repeat. At one point in time I changed the 'attribute' property to 'name' and my application stopped working. It seems that I had done something else (not sure what) and the problem had nothing to do with using 'name'. I've just tried to repeat it in isolation and I can't. Again, thanks.

Using a default entry with LookupDispatchAction ???
I am currently using LookupDispatchAction to handle all of the various
submit buttons on my form. But when this particular webpage is first
invoked, I would like to first pre-populate it with values. So I want to use
the same Action (Form bean) to handle pre-populating the webpage and then
handling
the later user modifications (after they have pressed any one of the
submit buttons).
I am thinking that I will probably need to use an HTML link to invoke it.
I was experimenting with something along these lines:
html:link page=/overview.do?action=initializeOverview/html:link
where this method would simply be included in the getKeyMethodMap.
protected Map getKeyMethodMap() {
Map map = new HashMap();
map.put(button.save.borrower1, saveBorrower1);
map.put(button.save.borrower2, saveBorrower2);
map.put(initialize, initialize);
return map;
}
But have not gotten this to work yet. Any help would be appreciated
thanks, Norman

We haven't formally discussed it on the STRUTS-DEV list yet, but I would assume that future versions of Struts will feature the use of the standard tags (JSTL now, JavaServer Faces when it's available) as the recommended approach for new apps.

The current and upcoming technologies I would definitely pay attention to for Struts related stuff: * Servlet 2.3 and 2.4 (especially filters and event listeners) * JSP Standard Tag Library (JSTL 1.0) and the recently added struts-el library in the contrib directory of the nightly builds that adds EL-compatible evaluations to existing Struts tags * JSP 2.0 (lots and lots of really cool things, including EL expressions everywhere and the ability to create custom tags out of chunks of JSP code) * JavaServer Faces (JSR-127) for user interface components * Portlet API (JSR-168) for writing portlets that can be run in any conforming portal server * JAXP/1.2 (part of the Java Web Services Developer Pack and Java XML Pack from java.sun.com) for the latest additions to XML parsing and transformations (JSTL includes lots of good tags for XML processing) * JAX-RPC/1.0 (part of the Java Web Services Developer Pack and Java XML Pack from java.sun.com) for integrating SOAP-based web services that can utilize the same business logic components as your Struts-based web applications do -- a reward for people who follow good MVC-oriented architecture principles :-) Much of this stuff is still in the future. If you're just starting out, don't feel shy about learning the existing Struts tag library and using it -- you've got lots of company. But, plan on migrating to standards based technologies as they become available to you in the future, to gain the benefits of competition between vendors on how well they implemented those technologies (all the while secure in the knowledge that your app will be portable). -- Vincent Stoessel Linux Systems Developer vincent xaymaca.com Craig -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Should I use a persistence layer?

However, if a user has 2 windows open on the same application. When he/she queries on one, then queries on another, and then comes back to the first window and click Next, he/she will get bad results. Does this lead to EJB or any other persistence layers?

RE: Multiple selected for html:select
The property attribute of the html:select must allow for capturing multiple items.
It should be a collection. Take a peek at html-select.jsp that is part of the
struts-exercise-taglib application that ships with Struts.
html:select property=foo size=4 multiple=true
html:options collection=managerList property=person_id
labelProperty=person.name / /html:select
Form bean --
private String[] foo;
public void setFoo(String[] in) { foo = in; }
public String[] getFoo() { return foo; }

RE: Where's the form-bean???
Hi Jeff, Is that because your Action is populating the form before forwarding to the page? And if not, what exactly is your Action doing? Brian Lowe, Jeff [EMAIL PROTECTED] 10/03/02 07:22am Hi Jason, Thanks for the reply. You've got it right in what I'm doing. However I think I could describe the problem more simply. The problem is that when validation fails and I'm forwarded back to the Action specified by the mapping's input attribute, the form that is passed in to Action.perform() is null. I'm puzzled because when the Action then forwards to the .JSP page, all the form values are populated.

I think I understand what you're doing, but feel free to ignore me if not. What I often do is to present availXXX object arrays to the front-end via request/session attributes that the front-end developer knows is meant to be a read-only informational array shared between different actions or action forms as the case may be. These availXXX arrays are typically used to populate selection boxes or to generate lists that are used as entry points into actions on specific items in the availXXX array.

I'm using two select boxes to implement the user selection metaphor where one contains available choices, and the other contains selected choices. If the form does not pass validation, I need to repopulate the selected choices from the array of its values, contained in the form bean. This is done in the action class that sets up all the data for the form. After I submit and validation fails, Struts forwards back to the input url, which is an action class. The problem is that the form object passed into perform() is null, so I can't get the array of values. What has me vexed is that after perform() forwards to the .jsp, all the form elements are populated as they were prior to submit, so the populated form exists, it's just not being passed in to perform(). I tried adding the name=formName attribute to the mapping, but then Struts tries to validate the form on the GET, as shown by the debug log below: -Processing a GET for /standards/curriculum-coverage-form -Looking for ActionForm bean under attribute 'curriculumCoverageReport' -Creating new ActionForm instance of class '...standards.CurriculumCoverageReportForm' -Storing instance under attribute 'curriculumCoverageReport' in scope 'request' -Populating bean properties from this request -Validating input form properties -No input form, but validation returned errors Any insight into this would be greatly appreciated.

RE: Should I use a persistence layer?
Yes. The standard approach is to only keep in memory results that are currently on the page. Have a persistence layer (either EJB or O/R mapping tool, or a combination of the two) page the results for you. i.e., you give it search criteria, sort criteria, a begin index, and an end index, and it gives you back the results. This solves two problems: The one you are encountering with bad results with two different windows, and the memory problems associated with very large result sets. There are examples of this sort of implementation out there; sorry I can't provide links. :( peace, Joe -Original Message- From: Chen, Dean (Zhun) [mailto:[EMAIL PROTECTED]] Sent: Thursday, October 03, 2002 10:13 AM To: 'Struts Users Mailing List' Subject: Should I use a persistence layer?

RE: Multiple selected for html:select
I solved this, not sure if it is good practice, but this might be useful to
others.
Below you will see that I am working with the managers Vector that contains
Person objects. I changed the select part to:
html:select property=managers size=4 multiple=true
And, added the following to my Person class:
public String toString()
{
return _id.toString();
}
Person.id is what I want to compare to managerList.person_id, and this
works! managers is still a Vector in a DynaActionForm. Finally, I am
starting to pick this stuff up.

Re: Tiles and Internationaliation
Hi, I am quite new to tiles stuff (only 1 and an half day experience, switching from Struts templates...) For the moment, I am just trying to insert internationalized messages in tiles and the only way I found to do this is: tiles:insert definition=portal.mainMenu tiles:put name=title valuebean:message key=help.stateProv.name//value /tiles:put /tiles:insert which doesn't satisfy me... I would like to be able to write instead: tiles:insert definition=portal.mainMenu tiles:put name=title value=help.stateProv.name/ /tiles:insert Could you please tell me if this is possible? Thanks in advance for your answer. Vince -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: Should I use a persistence layer?

The standard approach is to only keep in memory results that are currently on the page.

DynaFormAction problem
Hi everybody,
I have this action
!-- Editar institucion --
actionpath=/editarInstitucion
type=co.com.proveedores.EditarInstitucionAction
attribute=institucionForm
scope=request
validate=false
forward name=success path=/editarInstitucion.jsp/
/action
and this form-bean...
!-- Institucion form bean --
form-bean name=institucionForm
type=org.apache.struts.action.DynaActionForm
form-property name=action type=java.lang.String/
form-property name=id type=java.lang.String/
form-property name=name type=java.lang.String/
/form-bean
in EditarInstitucionAction I have this...
if(form==null){
DynaActionForm institucionForm = new DynaActionForm();
PropertyUtils.setSimpleProperty(institucionForm, action, crear);
PropertyUtils.setSimpleProperty(institucionForm, codigo, -1);
request.setAttribute(mapping.getAttribute(),institucionForm);
}
return (mapping.findForward(success));
then in editarInstitucion.jsp I have
logic:equal name=institucionForm property=action
scope=request value=crear
titlebean:message key=editarInstitucion.titulo.crear//title
/logic:equal
logic:equal name=institucionForm property=action
scope=request value=modificar
titlebean:message key=editarInstitucion.titulo.modificar//title
/logic:equal
I get this Exception
java.lang.NullPointerException
at
org.apache.commons.beanutils.PropertyUtils.setSimpleProperty(PropertyUtils.java:1548)
at
co.com.proveedores.EditarInstitucionAction.execute(EditarInstitucionAction.java:104)
If I make this changes...
if(form==null){
DynaActionForm institucionForm = new DynaActionForm();
request.setAttribute(mapping.getAttribute(),institucionForm);
}
return (mapping.findForward(success));
I get this Exception
javax.servlet.ServletException: Exception accessing property action for
bean institucionForm: java.lang.NullPointerException
at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:494)
at
org.apache.jsp.editarInstitucion_jsp._jspService(editarInstitucion_jsp.java:93)
What I'm doing wrong? Is there any other way to use DynaFormAction?
Thanks in advance,

RE: Should I use a persistence layer?
If they have 2 windows open they're likely to be in 2 different sessions. Not 'likely', only possibly. Most users are familiar with the new window concept, which in most browsers (IE for sure) retains the current session. A user will quickly realize it is faster to do a new window than having to open the browser again, go to the app. log in, etc. Frequent users often have multiple windows open that are part of the same session. Navigating search results in both of them is less likely though. :) Besides, how often do you think your users will do this? Good point. I don't know of any persistence layer that solves this problem. There's certainly not an out-of-the-box solution for this available. However, your UI framework and persistence layer can work in combination; the UI only retains results that are currently viewable, and goes back to the persistence layer to fetch for each pagination link. This means, of course, that you have to retain all search and sort criteria as well as the indices of the result set you are viewing in the UI layer so the information can be transmitted.
