I am using Tomcat4.0.1 , Cocoon 2.0.2 . I have my JSP's, they generate valid XML's. But I couldn't see them working with C2. I tried the JSP Generator and JSP Reader examples of C2 but they didn't work too. I put the error message below, maybe it will be helpful. Any help would be appreciated. -------------------------- -------------------------- An error occurred The org.apache.cocoon.www.sitemap_xmap notifies that org.apache.cocoon.ProcessingException says:
