When I debug a struts aplication,it fails and I get the error "java.lang.NullPointerException: Module 'null' not found." if the .jsp file contain tag.
And if I get rid of the ,it can run successfully with any other tags.
Can you help me with the problem?Welcome to ask for more info in point from me.

Are you maybe giving your "html:form" tag with no "action" attribute? maybe that's what it means by module "null", because you haven't specified any module in the "action"? (by default if your application has no explicitly named modules, you get a single default module with the empty module name so its path relative to the context root is "/", and that's how you usually specify an action like "/foo.do").

I have also faced same problem in the past but it get resolved.Issue was that Form bean entry was missing in the struts-config.xml.You can verify your struts-config to see if all form bean entries are there or not.
