This sounds like old question, but I am stuck in resolving the issue for my case.<br />
<br />
I am working on very big web application which has more than 20 modules. We kept the header and footer in a sperate module and the header.jsp and footer.jsp are including in all other modules through &nbsp;jsp:include &nbsp;tag. <br />
<br />
We are maintaining our own user entitlement model and I want to add user Role validation. If the user has roles in our entitlement, then redirect to PageA if not redirect to Login page (PageB). <br />
<br />
After adding this piece of code in header.jsp, it is not redirecting to different page which I required. On googgling, found that if we are including any pages using jsp:include the page redirection code in header.jsp will never works.<br />
<br />
Can someone please suggest the alternative ideas?

Redirect to Login page

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
