You are saying your servlet-api.jar contains the JSP API classes too? I would be concerned about two versions of a class being in the same classloader - but you say below that they are not packaged in the WAR. Can you upgrade to 7.0.21? There have been a few beneficial changes to the JSP components. You say below that the compiled tags & JSP don't appear to have been recompiled - either upgrade, or clear the work directory to ensure that they have been. p > However, these jars are provided maven dependencies.
