Re: ExceptionHandler not able to display error messages
I have written an ExceptionHandler that extends the struts exceptionHandler. I would like it to print a stack trace. So, I have done the following: have a look at this blog entry, and the ExceptionHandler and JSP page I use for displaying exception messages (and stacktraces) http://www.jroller.com/page/prpatel/20031023#handling_the_three_kinds_of HTH, Pratik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Populating the next Form
I have ActionA and FormA associated to screenA, similarly ActionB and FormB associated to screenB. Upon click of a button on ScreenA, I need to dispatch ScreenB with some values prefilled. I was wondering where should I be writing the logic to populate the FormB for showing those values prefilled on ScreenB. You can do it in either place (ActionA or ActionB). As someone has suggested, perhaps you want to keep everything together in *B. This really depends on how you wish to organize your Struts application. I like to keep things organized at a functional level, for example all actions to User objects (adding, updating, loading) are kept in one UserAction class. I then use MappingDispatchAction(*) to send a request to the appropriate UserAction method. This way, I can glance at the struts-config.xml and know where and what a specific action mapping is doing without having dig any deeper. *MappingDispatchAction is new and is not in 1.1 but in the nightly builds. cheers Pratik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: new to struts
can any one point the basic document regarding Struts which has given small examples. There's this amazing new search engine, called Google, which you can access at www.google.com. If you enter the words "Struts Tutorial" and click "Search" it will bring up a huge list of Struts related websites. Seriously though, you can find a raft of Struts tutorials here http://jakarta.apache.org/struts/resources/articles.html cheers Pratik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Exception handling - please help!

Please help me before I go insane... You are actually handling the exception in your Action class. You have to pass the exception up the (method) stack if you want to use the Struts exception handler. The action's method signature should be something like this: public SearchTradesAction extends Action throws Exception and you must remove the "catch" statements in the Action. Also, you will likely need a custom exception handler to populate ActionError messages.

Re: Cannot create a DynaValidatorForm
In validation.xml I added the following : First, don't put *anything* in the form when you submit it to see if the "required" validator is working. Second, remove the space here: depends="required, integer"> i.e. make it: depends="required,integer"> HTH, Pratik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Where do you specify the

Right now, I have a hand coded form and XDoclet creates the section of my
struts-config for me, but I'm not creating the actual ActionForm subclass with XDoclet.
In my domain objects; here's the objects from a Struts app I'm currently
working on:
Domain Object XDoclet Generated ActionForm
UserUserForm
Forum ForumForm
PostPostForm
Thread ThreadForm
Sample domain object:
package org.sourceforge.jwebforum.model;
import java.util.Date;
/**
* @struts.form include-all="true"
* extends="org.sourceforge.jwebforum.webapp.form.BaseForm"
*/
public class User {
private String password;
private String email;
private Date signupdate;
private String firstname;
private String lastname;
private String username;
private long userid;
public User(String password, String email, java.sql.Timestamp
signupdate, String firstname, String lastname, String username, long
userid) {
this.password = password;
this.email = email;
this.signupdate = signupdate;
this.firstname = firstname;
this.lastname = lastname;
this.username = username;
this.userid = userid;
}
public User() {
}
/** Password of the user.
* @struts.validator type="required" msgkey="errors.required"
*/
public String getPassword() {
return password;
}
...
I hope to have this Struts application uploaded to sourceforge within
two weeks (with full source, of course). It's still undergoing some
refactoring, but I can send you the current snapshot if you're interested.
cheers,

Re: How do I populate a DynaValidatorForm?
"DynaActionForms are not a drop-in replacement for ActionForms. If you
need to access ActionForm properties in your Action, you will need to
use the map-style accessor, like myForm.get("name"). If you actively use
the ActionForm object in your Action, then you may want to use
conventional ActionForms instead."
Why aren't you just using ActionForms? To be honest, I never use
DynaActionForms. Sure, there's an extra Java class that needs to be
written, but I find it easier to write an ActionForm class than write
out a XML descriptor for a DynaActionForm. Plus it's easier to unit test
a concrete class than one that assumes its properties at runtime. If
you're too lazy (like me) to actually write the ActionForm class, just
use XDoclet to generate one for you.

Re: Menu based on Tiles
I need to create a menu using tiles. The menu is a vertical menu, where the categories list comes as bold, and the currently selected menu should be expanded to show the submenus. The currently selected submenu's hyperlink should be disabled, rest have to be enabled. What is the best way to design such a tile? Are there any sample codes for the same? I don't think a menu would be dependant on Tiles per se. Sure, you could wire in a menu using a tile, but the menu code (jsp/javascript/html) would also work by itself outside of Tiles. While you think about it, have a look at this: http://raibledesigns.com/wiki/Wiki.jsp?page=StrutsMenu cheers, Pratik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
