Exception with custom portlet: content type is null

[vinkh]

I have deployed a custom portlet and when the portlet invokes the Jsp, it gives error -

java.lang.IllegalStateException: No content type defined

Can you tell me how the content type is set in the class FragmentResult as it is null in that class. ?.

I guess, the portlet/jsp as such are ok, since it was working well on another portal and i am trying to move it to jboss portal. Any one had similar issues ?. Any thing to do with the xml descriptor definitions for the portlet ?
eg - in -pages.xml, --<portal-name>default</portal-name>)--

[mholzner]

is your portlet code setting the content type at all, and is that content type supported according to your portlet.xml ?

The portlet just dispatch to a jsp

PortletRequestDispatcher prd = getPortletContext().getRequestDispatcher(mainPage);
 prd.include(request, response);

In the servlet compiled from the jsp, the content type is set.

_jspxFactory = JspFactory.getDefaultFactory();
 response.setContentType("text/html");
 pageContext = _jspxFactory.getPageContext(this, request, response,
 null, true, 8192, true);
 _jspx_page_context = pageContext;

Do i need to explicitely set the content type in the portlet ?. guess not

The problem is contentType is not set in the class org.jboss.portal.server.output.FragmentResult

I am using only the standard classes like RenderRequest, RenderResponse and NOT JBossRenderRequest, JBossRenderResponse etc... Is it like i have to use JBoss* classes ?
I could send the code if you want to have a quick look!

Sorry, i missed one part of your ques. The portlet.xml supports the content type

<supports>
 <mime-type>text/html</mime-type>
 <portlet-mode>EDIT</portlet-mode>
 <portlet-mode>HELP</portlet-mode>
 </supports>

I see the same behaviour. I can get around it by :
renderResponse.setContentType("text/html");
PortletRequestDispatcher rd = this.getPortletContext().getRequestDispatcher(uri);

if (rd != null)
{
rd.include(renderRequest, renderResponse);
}
else
{
writeError(renderResponse, uri);
}

Not sure if this is a bug, or a feature.....

[vinkh]

It works with renderResponse.setContentType("text/html"); .

So its setting this in the class org.jboss.portal.server.output.FragmentResult. But this makes an additional step from specifications and shouldn't have been this way (my opinion :-))

Thanks for your help, Martin!
