Hello David,

Thanks for the info - it won't be the first time I've botched aconfiguration :). Here's the stack trace:

Does this help?

There should be no issue using xul as long as it's declared in the
portlet definition.  I only see:

    contentType='text/xml'
    portletMode[0]='view'
    portletMode[1]='edit'
    portletMode[2]='help'

you'd want to add an entry for xul.

That doesn't explain your error though.  It seems to be more of a
configuration error.

This:

exception in PortletInvokerImpl at line 106:
ServletDefinition servletDefinition =
portletDefinition.getServletDefinition();



should not throw a NullPointer if servlet definition is null. . .it
only would if portletDefinition is null - which according to the
debugger it is not.  Also, according to the debugger, the servlet
definition is not null.

Any more information (i.e. that stack track), may be helpful.

Thanks,

David

Hello All,

I'm attempting to use a page with the xul markup "widget" language in a
portlet, and deploying it to pluto. I'm receiving a null pointer
exception in PortletInvokerImpl at line 106:
ServletDefinition servletDefinition =
portletDefinition.getServletDefinition();

I've attached a debugger and found that the
portletDefinition.getServletDefinition() is returning null. The debugger
was able to give me the following information about the portalDefinition
at run time:

I believe I have the portlet configured correctly. My gut instinct is
that the container simply doensn't support the xul markup language. Any
help would be appreciated.
