Hi Christopher, I have almost 27-30 apps in my tomcat.
Do I need to declare in every applications's META-INF\context.xml. And also I have a listener class which is in tomcat\lib folder, which also access these shared classes using CustomSharedLibrary. How can I access those shared libraries in listener which is in tomcat\lib folder? Regards, Akram.
