http://issues.apache.org/bugzilla/show_bug.cgi?id=34090 Summary: org.apache.catalina.util.CustomObjectInputStream causes problems Product: Tomcat 5 Version: 5.0.28 Platform: Other OS/Version: Windows 2000 Status: NEW Severity: major Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] Since tomcat 5.X, we are not able to load persistant sessions on tomcat start. The attached exception is thrown on tomcat start (s. below). After investigating the problem, it seems to be caused by the class org.apache.catalina.util.CustomObjectInputStream. The method defined there public Class resolveClass(ObjectStreamClass classDesc) throws ClassNotFoundException, IOException { return Class.forName(classDesc.getName(), false, classLoader); } doesn't have the fallback of it's superclass java.io.ObjectInputStream protected Class resolveClass(ObjectStreamClass desc) throws IOException, ClassNotFoundException { String name = desc.getName(); try { return Class.forName(name, false, latestUserDefinedLoader()); } catch (ClassNotFoundException ex) { Class cl = (Class) primClasses.get(name); if (cl != null) { return cl; } else { throw ex; } } } so primitive classes result in a java.lang.ClassNotFoundException. To prove this, I serialized our complete session-data with writeObject and readObject. Using the standard classes, no exception was thrown. Here's the exception: ClassNotFoundException while loading persisted sessions: java.lang.ClassNotFoundException: int java.lang.ClassNotFoundException: int at
