Render xform from servlet in a portlet

Hi,

I have a servlet which is running and rendering xforms without problems. Now, since there is no portlet filter for Orbeon Forms (it would not work in my environment anyhow) I try to use the PortletRequestDispatcher in a portlet to call the servlet for rendering my Xforms.

In MyPortlet.doView(RenderRequest request, RenderResponse response) I have
PortletContext ctx = getPortletContext();
PortletRequestDispatcher prd = ctx.getRequestDispatcher("/MyServlet");
response.setContentType("text/html");
prd.include(request, response);

This calls the servlet ok, but it seems that the servlet filter does not interfere with the response generated from the servlet. The result is that the xforms is not rendered correctly, but served as plain xforms-tags.

Anyone have an idea how I could get this thing working as wanted?

Re: Render xform from servlet in a portlet

Hello again,

I got this solved. Simple mistake by me, I used Servlet 2.3 instead of the required Servlet 2.4. Include dispatchers work only from 2.4 onwards. After I changed that I could add <dispatcher>INCLUDE</dispatcher> to my <filter-mapping>. Now the filter is called ok.

Thanks for letting us know.

Somewhat related, we recently updated the documentation or the XForms
filter to also use Servlet 2.4 and the "new" <dispatcher> element:

<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
