    What do you mean with external lib?

     

    i know what external is and what lib is but the combination of it is for me new.

    I have a library developed by a third party (external) that I want to use.

     

    This one to be exact - http://xstream.codehaus.org/download.html

    I download it, drop it in the libs folder and add it to my class path.

    I also found some information stating i should add it to the mods dir to have it get added to the class path.

     

    When I actually try to use it I get a Java null pointer exception, as outlined below.
