jsr 168 struts portletURI problem on WP 5.1
|
|
|
| Hello,
I am new to Struts Framework. I am developing a Struts based JSR 168 portlet on WepSphere Portal 5.1 platform. I needed some help with an error I am getting in generating Portlet URI's within the struts Action class. I am using this method to generate str
uts action url mentioned in the Forwards and Redirect option of this page in WP 5.1 info center. http://publib.boulder.ibm.com/infoc...pstrsource.html
PortletApiUtils portletUtils = PortletApiUtils.getUtilsInstance();
Object portletURI = null;
if (portletUtils != null)
{
// when run in a portlet use this execution path.
Object pResponse = portletUtils.getPortletResponse( (HttpServletRequest) request );
try {
portletURI = portletUtils.createPortletURIWithStrutsURL(request, url);
// don't need to call response.encodeURL, the portletURI.toString takes care of that.
}
channel.setLocation(portletURI.toString());
Here channel is a component within my portlet which has link to a struts action...
I am getting the following error when i try to run the jsr 168 portlet within RAD WP 5.1 test environment..

I am getting this classCastException at this line
portletURI = portletUtils.createPortletURIWithStrutsURL(request, url);
I have taken the code to creating Portlet URI straight from the infocenter.. May be I am missing something about using JSR 168 with struts api. I would appreciate any help or tips with this problem...

| Maybe you are using the incorrect request Processor. I remember that I had to change it myself:
com.ibm.portal.struts.portlet.WpRequestProcessor
This goes in the struts-config.xml file under "controller"
Give it a try. Not sure if that is it or not, though. Good luck!

Thanks for the reply. I am using the correct request Processor. After many hours of searching on the net, I came to know that my Struts Action class has to implement IStrutsPrepareRender interface. The sample code which comes with IBM Struts Portlet Frame
work (SPFStandardTransformation.war) contains an example of Struts Action which uses PortletApiUtils class to create a struts action URI using the same code in WP 5.1 infocenter. I think the infocenter should mention about implementing the interface (IStr
utsPrepareRender ) in the Struts Action Class. This would have save me lot of pain !!. Anyways Thanks for the reply.
