/virgoDev/zmq/v2r0p9/lib As I mentioned before, there is no problem with the library location since I added a stdout message on load success. It is a naming problem, the jvm <http://www.velocityreviews.com/forums/t371398-java-lang-unsatisfiedlinkerror.html#>is unable to find the methods it expects to find in the native library. I caught that point from a forum which may help: Note that the DLL is necessarily written to be used from a particular Java class <http://www.velocityreviews.com/forums/t371398-java-lang-unsatisfiedlinkerror.html#>. That class declares a number of native methods, and the DLL contains implementations of those methods. You cannot load the same DLL from another class and expect to be able to use those methods as though they belonged to the new class, because the method names in the DLL are determined (in part) by the name of the class they belong to. Did you rename the class the dll was intended to be used from? Did you change its package declaration? _______________________________________________ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
