JCA calling a DLL

[aknight]

Hi, we have a legacy system which is implemented in C++. We use a standalone Java App and JNI to call the C++ at the moment, but want to use JBoss.

Is it possible for me to implement a JCA component which will wrap up the DLL? At the moment, I'm getting an UnsatisfiedLinkError. I have the example from the documentation working, but cannot seem to get it to call my DLL.

Thanks in advance.

The dll needs to be in the path/library path of JBoss.

Beyond that, the common error is to get the JNI mangled name wrong.
