RE: load data from db into form
Jiri, What action class does your action extend? If it is org.apache.struts.action.Action, then the parameter field, which you appear to have filled in with what seems to be a tiles definition, is ignored. The parameter field does nothing unless it is a subclass of Action, such as ForwardAction, DispatchAction, etc. Those sub-classes used the contents of the optional "parameter" field to perform an action they were designed for: ForwardAction assumes the contents of the parameter field is a tile or jsp path to forward to while the DispatchAction assumes the contents of the parameter field is to be used a form field name to determine what function to execute. When you put your return as a mapping.findForward("success"), where do you define a forward named success? You must define a forward either in the global forwards section, or in the action. Since you said I corrected for the form bean error, here is the old action without the forwards: You should define "success", "failure", or anything else you plan to use as a mapping.findForward("SOMETHINGHERE") in your action or in the global-forwards section. An action would be setup a bit like this: I actually did some searching on the parameter="something" last week wondering what the normal Action class does with it and found out it does nothing. It is for you to pass information to your action on the fly and access using getParameter() and setParameter(). In the case of ActionForwards or other action subclasses, it has specific means that assist in the function of those subclasses.

displaying collections after a validate() error
Hi, could someone suggest what I'm doing wrong here? I've got a form with an associated ActionForm, several members of which are collections. I display them like this: [] Whilst single valued fields are displayed like: All seems well, and everything displays fine. However, the ActionForm has a validate() method, which send the user back at the form, which displays some error messages. When this happens, however, the JSP doesn't display the collections from the ActionForm, only single valued fields.

force caching staticJavascript.jsp
Hi, as validator framework suggest, is possible to avoid downloading static functions for validation for every JSP, by creating the page: <%@ page contentType="application/x-javascript" %> <%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %> which would hold static functions called from the dynamic ones in the pages with forms. However, when set for the whole app, staticJavascript.jsp is not cached by browser and is returned again by every JSP page which includes validation to the browser. How could we tell staticJavacript.jsp that it is an exception and MUST be cached in the client browser. I think it is a common issue, so I hope someone could have a solution.

Re: J2EE IDE
This is nonsense. I use NetBeans 3.5.1 with j2sdk1.4.2, and I rarely restart it (manually or through a crash) more than one a week. Right now it has been running for over three weeks fine. The speed issue is relative, what is slow? NetBeans 3.5.x version was primarily improvements to performance in the IDE, now it is very fast and responsive. I have never had any problems with speed on this version of NetBeans. (Unless you choose to turn on every single plug in, and try experimenting with everyone at once, ... eclipse users complain about poor performance under these conditions as well). Oh, and to have a jab, didn't IBM try to announce Eclipse as the first open source true Java IDE? NetBeans was open source a good year or two before Eclipse, and Eclipse isn't 100% java!! It is an interesting reflection between Sun and IBM, Sun focus' more on technical issues and IBM more on marketing. Nonetheless it is great the two opensource IDEs exist to encourage competition between the two camps. Mick.

Re: load data from db into form
Hi guys, could be many whys, but it looks like your form bean is null. have you configured your struts-config mapping correctly to reference this form? You should also cast the form bean into the type of form class you have specified, since it is passed into the action as the super class ActionForm.

Handling Exceptions
Hi, In struts-config, I have defined few global-exceptions such as these I also have created an error page, error.jsp with <%@ page isErrorPage="true" %> and at the top of the jsp template for all the pages a <%@ page errorPage="error.jsp" %>. However, when a ServletException occurs, it does not go to the path defined in struts-config.xml. Somehow, the error is still showing in the application page and not in any one of the error pages defined. Thanks Amin

best practices for ActionForm flow control
When the actionForm validate method returns errors, struts direct the control to the jsp page specified in the input parameter of form mapping. is it possible to direct control to the action class in case of error inside the actionForm validate method without making extra coding effort, or playing with some configurations ?

Hi James, David, Mike, everyone, thanks for the input. For some reason yesterday I wasn't fully on the ball, but today your suggestions gave me a better idea - I can do it without using the extra tag library, so: <%=org.apache.struts.Globals.ERROR_KEY %> Oh look! Errors! Also, thanks for shaming me into using the Taglibs user list. I shall from now on. Just posting this here to finish the thread. I already subscribe to this list, tomcat-user, ant-user, emacs, linux, and occasionally mozilla browser and mozilla mail, xml, jdbc, mysql when necessary (oh and Van Morrison) so it gets to a point sometimes where I just don't recognise names anymore and it loses something in the transition. I guess it's one of the drawbacks of working on my own and doing it all myself, not being able to specialize :( By the way I do have the JSTL spec and I have read it - the problem with specs is that they tell you what they can do, but don't tell you what they can't do, or what the downside is.

struts / tiles forward problems
Hi, I am new to struts & tiles and have several questions/problems That I am currently dealing with: 1) although a page ( say tiles.page ) is defined in my tiles-def.xml and referenced in my struts-config.xml like and a link from a jsp page ... resolves to a link to 'tiles.page' ( textual!) without resolving the tiles definition ? 2) is it generally possible to nest ( not to extend) tile definitions ? 3) is there a simple solution for using the struts forward mechanism programmatically ? I'd like to have either an action or a tag which I could call in a jsp with something like: mapping.findForward(request.getParameter("struts.page")); regards Johannes - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: dinamically add href into html:link
Thanks, I used html-el and it works. what is the better to use, use c:url or html-el:link? Or it is equivalent here? And one more queestion: I have object with application persistency (over all sessions), and for session I call some method to set some parameter and get another object (array list) and maybe store it in session. Now I do: and, now provisory, this as scriptlet: <% a.setRequest(request); User user = (User)session.getAttribute("user"); if(user != null){ a.setUser(user); } getServletContext().setAttribute("b", a.getSomething().toArray()); %> next, I call some cykle for "b" object.

Re: Handling Exceptions

Somehow, the error is still showing in the > application page and not in any one of the error pages defined. My guess is, the ServletException is happening someplace where Struts' ExceptionHandler can't get hold of it, e.g. on your JSP page. Have a look at your servlet container's logfiles to see exactly where they appear. You can still define an error-page in your *web.xml* to catch those and redirect them to your own error-page.

Re: load data from db into form
Yes, nested tags, I must look at ... so now I have it without nested, form definition is now without it. but still I got java.lang.IllegalArgumentException: No destination bean specified at org.apache.commons.beanutils.BeanUtils.copyProperties(BeanUtils.java:220) at cz.chalu.struts.modules.completeregister.LoadDataAction.execute(LoadDataAction.java:32) What is missing? I my action class (execute method) I have: public ActionForward execute(...){ LoadDataService service = new LoadDataService(); ComplRegisterDTO registerDTO = service.loadUser(request); BeanUtils.copyProperties(form, registerDTO); return null; } If I understand well, in BeanUtils.copyProperties I copy data from DTO into form defined in execute method?
