Re: ClassCastException:JavaURLContext cannot be cast to class org.xx.xxx
I was actually able to solve this issue. My Html page had a form component and that why there was a form component in the code. -- Sent from: http://apache-wicket.1842946.n4.nabble.com/Users-forum-f1842947.html - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: ClassCastException:JavaURLContext cannot be cast to class org.xx.xxx
There is no formComponents in your form.
So why do you use a form ?

ClassCastException:JavaURLContext cannot be cast to class org.xx.xxx
I have been on this issue for atleast 2 weeks now. Trying to use Wicket with
EJB. This occurs when I use @EJb for either a stateless or stateful bean .
*My code below
The webpage which has the EJB as a variable*
public class PartnersZipCode extends PrescientTemplateOriginalPage{
@EJB(name = "ejb/publishZipCodes")
transient private PublishZipCodes partnerInterests;
@EJB

private String sessionZip="sessionZip";
private String sessionEmail="sessionEmail";
private String nameFromSession;
private String dbKeys="dbKeys";
private Vector forkeys;
private Form zipCodeFormOfInterest;
private Label partnerOne;
private Label partnerTwo;
private Label interestedZips;
private Collection listOfZips;
public PartnersZipCode() {
zipCodeFormOfInterest=new Form("zipCodeFormOfInterest");
partnerOne=new Label("partnerOne");
partnerTwo=new Label("partnerTwo");
interestedZips=new Label("interestedZips");
zipCodeFormOfInterest.add(partnerOne);
zipCodeFormOfInterest.add(partnerTwo);
zipCodeFormOfInterest.add(interestedZips);
add(zipCodeFormOfInterest);
nameFromSession=(String) getSession().getAttribute(sessionEmail);
