Hello Sorry to drag this issue on but, I still don't get Tomcat 5 to recognize classes in jar files located in $CATALINA_HOME/shared/lib
I tried my orginal application (which was running fine under Tomcat 4.1.x, both on Windows and Linux) with Tomcat 5.0.28 and then with 5.0.16, both under Windows and Linux, but the problem with the ClassNotFoundEception still occurred. Then I decided to reduce as many potential problem areas as possible, by writing a new very simple application consisting of only one html page and one servlet, and only one external jar-file. (My original application was quite large with many jar dependencies) So I started up my IDE, created the new application, created the servlet, deployed in tomcat 4.1.x and, placed the jar-file in /shared/lib and of course it works. Then I deployed under Tomcat 5.0.28, but no, it does not work. After moving the jarfile to /common/lib it works though. This really puzzels me. What can I do to get to the bottom with this ? Is there any specific configuration that I could have missed ? Any other test cases I should perform ? Should I send my code to someone for inspection ?
