Hi Friends,

I need to communicate to a servlet present in another web application of the same web container.

As I googled, I found of using getServletContext().getContext("/Cart");

Current web application is "HelloWorld" and I need to commuicate to Cart.

So i invoked

But I printed the value of otherContext, it is null.

so I not able to forward the req and res.

Please help.

Generally, this won't work. It can be made to work on some servlet containers via proprietary means. For Tomcat, that's what the crossContext attribute does.

In a security conscious environment, the servlet container may return null for a given URL.
just check out about security issues..

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link:
