You may check EJB specification: "A enterprise bean must not attempt to load a native library. This function is reserved for the EJB Container. Allowing the enterprise bean to load native code would create a security hole."
Either a native library wrapped by Java classes or a pure native library are same thing.

I used it in servlets that deployed in IBM Websphere Application Server 3.5.3. In the servlet, I used System.loadLibrary("SWEOJNI"). It works. I search it online. Somebody suggested the permession in server.policy file can be changed to loadLibrary. I tried a couple of times. It failed because I don't know how? Any suggestion?
