<portlet:defineObjects/>
Hello
I have a problem with this tag, when I place it inside my jsp page, it generates an exception.
The jsp page looks like this:
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %> <portlet:defineObjects/> <form method="POST" action="<%= renderResponse.createActionURL().toString() %>"> <input type="text" name="text"/> <input type="submit" name="submitform"/> </form>
The portlet class:
public class HelloWorldPortlet extends GenericPortlet
{
public void processAction(ActionRequest request, ActionResponse response) throws PortletModeException
{
}
public void render(RenderRequest request, RenderResponse response) throws IOException, PortletException
{
response.setContentType("text/html");
PortletRequestDispatcher rd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/hello.jsp");
rd.include(request, response);
}
}This is the stack trace:

If I remove the <portlet:defineObjects/> tag, everything works fine. This is weird...
I'm using JBoss 4.0.2 and JBoss Portal 2.0 (binaries).
Does anybody know what the problem is? Thank you in advance.
