http://nagoya.apache.org/bugzilla/show_bug.cgi?id=17523 Servlet can't getSession Summary: Servlet can't getSession Product: Tomcat 4 Version: 4.1.18 Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Problem occur when I start tomcat (with securityManager) and try to run one servlet that uses Session, I got ClassNotFound Exception. If I load one jsp page that uses session it works and then the session will work for the servlets too. Why this ? The Class needed is inside server/lib/tomcat-coyote.jar This lib are not available to applications. I don't know why it works for JSP as it is inside common/lib/jasper-compiler.jar common/lib/jasper-runtime.jar And in my mind I have read in some place, the classes in common also can't access classes in server/lib. Probably the solution for this is to include in org/apache/catalina/startup/SecurityClassLoad.java or org/apache/coyote/tomcat4/CoyoteRequest.java to load the class : org/apache/coyote/tomcat4/CoyoteRequest$PrivilegedGetSession I don't have here the correct environment to build Tomcat and test one of this solutions.
