Java HotSpot Virtual Machine

hello, there:

I wanted to test the tibco queue. I started rvd and tried the following code which is a simple server, however, I got an exception like below:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Library not found: tibrvnative
at com.tibco.tibrv.Tibrv.loadNativeLibrary(Tibrv.java:355)
at com.tibco.tibrv.Tibrv.<clinit>(Tibrv.java:67)
at SimpleTestServer.<init>(SimpleTestServer.java:28)
at SimpleTestServer.main(SimpleTestServer.java:19)

from the doc it seems I need to have sth related to JNI, but I don't know what to do next. Can anyone with Tibco or JNI experience enlight me please?

Thank you very much
