error while loading gridsphere

[gayathri namala]

Hi,

I have been working on gridsphere for a couple of days. I am using  gridsphere 3.0.8, tomcat 5.5.25 and ant 1.7.0. I could install and load a hello world portlet. I tried  downloading another project and compiling the source code by storing the necessary library files in the lib directory of gridsphere(not the one in the projects folder). Though the build was successful I was getting the following error when I tried loading it.

GridSphere portal failed to initialize!

Unable to create a dispatcher for portlet: JSR Portlet Servlet Make sure the servletName: PortletServlet is the servlet-name defined in web.xml Stack Trace:
