Check if a class is on classpath in IJavaProject

Question

I got a IJavaProject and a class in fqnd: "com.example.urgs.ClassName".

How do I figure out if it is in the Project?

edit:

    String value = "com.example.xx.Generator";

    IJavaProject ijp = JavaCore.create(this.getProject(parameterValue));
    try {
        if(ijp.findType(value) == null){
            return error("Generator class does not exist.");
        }
    } catch (JavaModelException e) {
        // Stacktrace
        e.printStackTrace();
    }

This works for me ;)

edit2: parameterValue can be anything thats in the workspace.

You aren't use stackoverflow correctly. You should never edit question to add the answer. It is ok to answer your own question, but you need to post it as an answer. — Konstantin Komissarchik, Jun 04 '13 at 17:58

Try to load the class with something like this Class.forName("com.example.urgs.ClassName")

If the class cannot be located throws ClassNotFoundException
