Precompiling JSPs: Is that server specific?


Since JSPs adhere to a standard API, can I precompile them in my projects and then deploy the result on any server?

Specifically, I'm using Tomcat, JBoss and WebSphere.


Solution

  • No, not really. If you look at the java source that gets created by the JSP compiler, you'll see that it extends a base class that's proprietary to the container. For example, JBoss 4's servlet container generates JSP classes that extend org.apache.jasper.runtime.HttpJspBase, which is Tomcat and JBossWeb-specific.

    So you might be able to reuse pre-compiled JSPs between different tomcat-based servers, but even then it might not work.
