I am doing a webapp in struts... i'm using a sample program i found during
my web searches.
I was able to do fine, like saving and deleting but i always seem to get
this error whenever i
try to setting the form to the session in my edit action.
My code is:
GetUserAccountService service = null;
UserAccountForm userAccountForm = null;
if(tmUserId != null){
service = new GetUserAccountService();
userAccountForm = new UserAccountForm();
service.setServlet(servlet);
userAccountForm = service.getUserAccount(Integer.parseInt(tmUserId));
form = (ActionForm)userAccountForm;
if( form == null){
System.err.println("---> userAccountForm is Null!");
}
System.err.println("---> Test form.getUserid: " +
userAccountForm.getUserid());
System.err.println("---> Test form.getUsername: " +
userAccountForm.getUsername());
System.err.println("---> Test mapping: " + mapping.getAttribute());
//Save form in session for editing
try{
session.setAttribute(mapping.getAttribute(), form);
request.setAttribute(mapping.getAttribute(), form);
}catch (Exception e) {
System.err.println("ERROR:"+e.getMessage());
e.printStackTrace(System.err);
}
}
>>>>>
the error is:
