PDFNet for JAVA (Linux): How do I resolve "Native Library already loaded in another classloader"?

Q: On the same Linux server I have 2 web application with pdftron
sdk, but it
works only the first accessed, If I restart jboss, and sign the
that first error, everything works, is a problem of license?

threw exception
java.lang.UnsatisfiedLinkError: Native Library /usr/lib/libPDFNetC.so
already loaded in another classloader

A: You need to configure your web server so that native libraries are
loaded only once. This seems to be a common question on the Net. For
example: http://forums.sun.com/thread.jspa?threadID=633985 or search
