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
application
that first error, everything works, is a problem of license?

[org.apache.catalina.core.ContainerBase.[jboss.web].[/]
.[azstyle]] (ajp-127.0.0.1-8009-7) Servlet.service() for servlet
azstyle
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
for “Native Library already loaded in another classloader”.
