Hi,

We are running Linux 2.6.9-22.EL with Jre 1.4.2 on a AMD-64 machine. We
have an application that opens a DatagramSocket connection and sends a
packet. The application works fine as standalone application. But, when
invoked through a servlet, there is unsatisfied link error from
libnio.so for libnet.so, whereas libnet.so is available in the PATH
that the exception shows up.

Also, when we replace the Jre with 1.5 everything works fine. So, we
are confused... :-(

Any insight into this problem will be highly appreciated.

Thanks,
Suresh R

If the problem is only in the servlet then it's probably something wrong with
the configuration of the servlet engine. What engine are you using?

I use Tomcat5 on a very similar setup, 2.6.9-22.EL, Opteron, and jre 1.4.2_11.
The servlets I am running on this setup are part of the AstroGrid
(http://www.astrtrogrid.org.uk) project, so make heavy use of networking code.
There is no issue here with unsatisfied external links for libnet.so.
