Initialize Struts form with request parameters
Hi all, I have a problem with struts form. The form is: html:form action=chooseTrainee html:hidden property=traineeId/ html:text property=name/ html:submit value=Submit/ /html:form and the ActionForm has the following properties (fields and getters/setters): traineeId name What I want is: the traineeId must be initialized by a value passed via URL: e.g: http://localhost/test/chooseTraineePage.jsp?traineeId=12345 How can I do that? Your reply is highly appreciated!

RE: Initialize Struts form with request parameters
Well, honestly it isn't recommended that you do things this way. Struts is all about separating your model from your view, and you are wanting to modify the model. That's smack dab in the realm of Actions, so you should be doing it there. The Action would then forward to your JSP. Modifying ActionForms from within a JSP flies in the face of what Struts was designed to do. What you'll want to do is have an Action that gets called before your JSP is displayed. You're URL would look like this: http://localhost/test/chooseTraineePage.do?traineeId=12345 The .do is the only difference. From within the mapping defined in your struts-config for chooseTraineePage you would have the following (in your execute/perform method): ChooseTraineeForm ctForm = (ChooseTraineeForm) form; ctForm.setTraineeId(request.getParameter(traineeId)); ctForm.setName(request.getParameter(name)); request.addParameter(chooseTrainee, ctForm); return mapping.findForward(success); This is off the top of my head, so the syntax may be wrong, but the flow is correct. -= James -Original Message- From: Tien Nguyen [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 01, 2003 9:07 AM To: 'Struts Users Mailing List'; [EMAIL PROTECTED] Subject: Initialize Struts form with request parameters Hi all, I have a problem with struts form.

Re: Initialize Struts form with request parameters
This would happen automatically if you access the JSP via an action mapping in your struts-config. You specify the action class, the action form and the forward/jsp. struts will automatically instantiate the form when the request comes in and populate the form properties with any equivalent request parameters. hth Adam Tien Nguyen wrote: Hi all, I have a problem with struts form.

Re: Initialize Struts form with request parameters
Adam's answer is absolutely correct, however let me add more details to make your job a little bit easier. 1. Create and action called loadTrainee.do and associate this action with your form. with a forward to chooseTraineePage.jsp 2. Invoke chooseTranies.do?traineeId=, struts, will call the action in 1 and automatically populate your form's traineeId for you 3. In action1, write some code to use traineeId to fill name, struts will then forward your form to chooseTraineePage.jsp to display In summary, you need 2 actions, one to to load the form and the other one is to manipulate the form Hope this helps -D - Original Message - From: Adam Hardy [EMAIL PROTECTED] Newsgroups: Struts Sent: Tuesday, July 01, 2003 7:26 AM Subject: Re: Initialize Struts form with request parameters This would happen automatically if you access the JSP via an action mapping in your struts-config.
