    Do you mean by calling a DLL being able to invoke a method contained in a class that may reside on another system? If that is the case you might want to check out the post on dynamic object creation in this forum.

    yeah, you'll need to use native classes which should be avoided like the plague unless you really really really have to. they reduce the platform independence of your project. most things tho you can usually accomplish through java's many classes so that you really shuld need to use a .dll, what .dll are you trying to use? maybe there is a java one you can use instead...

    try using this: http://babelfish.altavista.com/ and set it to:
    French to English


    also i found this on the sun site:
    http://java.sun.com/docs/books/tutor...1.1/index.html

    it was right there... all i had to do was search for "native classes"

    did you try translating that french page from intervenat w/ babelfish then?


    basically you need to write native code (ie. platform specific code eg. c\c++ pascal turing asm etc.) and then make the wrapper that lets java know how to interact w/ the native code (this is the .h header file i believe, similiar to MASM32 proto libraries)
