Problem
I'm working in a Java project where the axis 2 library from Apache is being used. The axis 2 library is composed of about 20 jar files and some of these are not used project. What I want to know if there is a method to identify which of those jar files are the unused ones. I'm using the Eclipse IDE an I thought that one way to solve the problem is to add one jar at time until the I get no error messages about the missing classes. However, I'm not sure if this will work as some of the missing classes errors show up only at runtime. Does anyone know a better way to solve this problem?
