http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6884 Need Better Error Handling in WebappClassLoader.validateJarFile Summary: Need Better Error Handling in WebappClassLoader.validateJarFile Product: Tomcat 4 Version: 4.0.3 Final Platform: All OS/Version: All Status: NEW Severity: Minor Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Our application stopped working when we migrated from 4.0.1 to 4.0.2; we would get NoClassDefFoundErrors thrown for one of our classes. This class resides in a jar file inside WEB-INF/lib. As it turns out, we had packaged some J2SE classes (com.sun.jndi and javax.security) in that jar. I understand the meaning of section 9.7.2 of the servlet 2.3 spec; however, I think the current implementation needs to do one (or more) of the following so that folks understand what's going on when they get this error: 1. Log an error of some kind. Even setting the loader to debug="99" did not result in an error message; validateJarFile just returns false and the jar does not get loaded. 2. Throw an exception indicating that the jar cannot be loaded, and indicate the guilty class in question. 3. Load "acceptable" classes from the jar file, but not the offending ones. This is a very difficult problem to debug for someone unfamiliar with the Tomcat source code.
