    You can't directly. They are totally different classloaders and you won't be able to access classes from one in the other.

    You have two choices:
    1. Create a common library (jar file) that will be installed in both web apps that contains the methods you need.
    2. Use something like HttpClient and call the method as if you were a browser or other client. If you're structured in a SOA (Service oriented architecture) manner this shouldn't be too bad. If you're not it will be somewhat harder.
