Your code may be dependent on a bug in 4.1 that was fixed in later Tomcat levels. There are a set of system properties you can adjust to change the 5.5 behavior to be the same as in 4.1, and you might need to experiment with those: http://tomcat.apache.org/tomcat-5.5-doc/config/systemprops.html In particular, look at the ones in the Jasper section. Also, Tomcat 6 implemented several more Jasper-related properties that might be pertinent (hard to tell without seeing your code). Since you're upgrading, why not move to Tomcat 6.0? It's noticeably better in many ways than 5.5. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
