Answer 1

The classpath loader defaults to the JVM classpath. Use this to get the classpath loader for the current class if it is in the same jar/location as your class you are trying to get an instance of:

    ClassPool pool = ClassPool.getDefault();
    ClassClassPath ccpath = new ClassClassPath(this.getClass());
    pool.insertClassPath(ccpath);
    CtClass superClass =    pool.get("com.some.TestClass");

Answer 2

I had a similar issue where it works in eclipse but when deployed in tomcat, it throws error. It could be because in eclipse you provide some jar files in different locations and use it in class path.

Hence make sure all your jars are available in project lib folder

Answer 3

Is your WAR file getting built correctly and including all of your compiled classes and needed libraries under WEB-INF\classes and WEB-INF\lib respectively?

Answer 4

looks like a library is missing in your war - which is only present in your eclipse configuration.
