Hi, I also have had similar problems with an InvocationTargetException being thrown by StartTomcat. I am using VisualAge 3.0 Enterprise and Tomcat 3.2.2, following instructions found in http://www7.software.ibm.com/vad.nsf/Data/Document2390?OpenDocument I also have made the suggested code change to the main in StartTomcat, overcome the issue of passing arguments and setting the home to "." in the main of StartTomcat. Have you any other suggestions, as to what the cause is? Cheers Jayne
