Thanks for your replies.
I have some questions about it though:
<c:import> will work for any URL.
How do I find the full URL of the jsp I want to import? I tried adding the path but it didn't work ... If I put in the URL the full path I get a so I don't think I can just add that one (actually I did and it didn't work): //server/path/myjsp.jsp
javax.servlet.jsp.JspException: Cannot find bean Headers in any scope
The jsp I want to include is also included in the App_A so i guess i need it to send me whatever is the result text after it has compute, it cannot compute from my App_B.... sorry it this is a bit confusing.
As for:
servletContext.getServletContext("/someOtherContext")
What would the "someOtherContext" be? the apps are running on Weblogic by the way. When I check on weblogic it says for the App_A I want to include:
Context Root: (No Value Assigned)
The Context Root for App_B (where the include is) has some values, so how do I reference an app that has no context root assigned?
Thanks
