Re: passing parameter between a view and an action with

[alexj]

I just change the to url to href="/ibmss/getstudent.do paramId="name"
paramProperty="name"/> and

I didn't get any error but I'm still having trouble when I will populate a
form with
the datas I get from the preceding view.

In fact what I want to do is to when a user select a person in my view page
(where I have defined the link) is to pass all the datas to an action named
getstudent.

In this action I create a new ActionForm and populate with the datas I just
pick from my action. I 've do some System.out.println just to test if my
datas was taken. But I'm still having trouble when I want to forward
theses datas to an editstudent view page.

I define in my getstudent action an execute method who do this job :

public ActionForward execute(
 ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response)
 throws Exception {

try {
  form = buildStudent(request.getParameter("name"));
  if (form == null) {
 System.out.println ("form nulle");
   }
  if ("request".equals(mapping.getScope() )) {
      System.out.println("<<<----request---->>>");
      request.setAttribute(mapping.getAttribute(), form);
   }
  else {
     System.out.println("<<<----session---->>>");
     HttpSession session = request.getSession();
     session.setAttribute(mapping.getAttribute(), form);  }
    }
  catch (Exception ex) {
  }
  return mapping.findForward("success");

The buildStudent(request.getParameter("name"))
method build me the a new form with the existing
datas.

But when I run my editstudent view page have blank field.

My mapping is defined this way :

<action

attribute="studentForm"

input="/form/editstudent.jsp"

name="studentForm"

path="/editstudent"

type="soft.ibmss.struts.action.Action">

<forward name="success" path="/editstudent.do" />

<forward name="failure" path="/form/viewstudent.jsp" />

</action>



<action

path="/getstudent"

name="studentForm"

scope="request"

validate="false"

type="soft.ibmss.struts.action.GetstudentAction">

<forward name="success" path="/form/editstudent.jsp" />

</action>

Any idea ????

Thank you in advance.
