Struts and JSP problem :(

[Roberto Diaz]

I am new to JSP and Struts development. I have a display only form that
I have mapped to an ActionForm and an ActionClass. The form is displayed
OK, but I don't get any data in it. It is just a standalone form and am
trying to set the values for the form fields using Action class.
I am posting code snippets here:
*******ActionForm*************
public class page14ActionForm extends ActionForm
{

private String username;
private String name;
private String location;
public void setUsername(String username)
{
this.username = username;
}
public void setName(String name)
{
this.name = name;
}
...........
}
*******Action Class**********
public class page14Action extends Action
{
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{

page14ActionForm aForm = (page14ActionForm)form;

String uname="John" ;
request.setAttribute("username",uname);

return(mapping.findForward("success")) ;
}
}
**** JSP PAGE (Posting only for one field) ******
<html:form action="page14" name="page14Form" type="page14ActionForm" >
<table id="pg14table1" align="center" width="343" cellpadding="2" cellspacing="2">
<tr align="center">
<td ><bean:message key="app.username" /></td>
<td>
<html:text property="username" readonly="true" />

<bean efine id="username" name="page14Form" property="username" />
</td>
</tr>
******* STRUTS CONFIG************
<form-beans>
<form-bean name="page14Form" type="page14ActionForm" />
</form-beans>
<action-mappings>
<action path="/page14" type="page14Action"
name="page14Form" input="/common/page14.jsp" scope="request">

<forward name="success" path="/common/header.jsp" />
<forward name="failure" path="/common/footer.jsp" />
</action>
</action-mappings>
What am I missing here? I get a message cannot set null value. So looks like username is null, but why ?? I am setting it in ActionClass .
Any help is greatly appreciated.
Thanks in advance for all the responses.

With this code:
String uname="John" ;
request.setAttribute("username",uname);
In your Action you're setting a request attribute of "username" to "John". What you really want to be doing is setting a property of your ActionForm so that
<html:text property="username" readonly="true" />
returns with "John".
Try this in your Action instead:
aForm.setUsername("John");
Hope this helps.
Matt.
