System.LoadLibrary(); does not take a absolute path, but i did try
using System.load() which can accept a full path to the library and
the library does load at compile time (no errors at the System.Load()
line), but at runtime i am still getting a
UnsatisfiedLinkError when ever i try to use any of the functions from
the library.

System.load("/etc/tomcat5/webapps/my_test/WEB-INF/src/libmapscript.so");

yes i do get a class file and use all the basic java functions when i
remove all the lines that are giveing my trouble.

I have also place the .jar and .so files in the WEB-INF of the servelt
that i am creating, still no luck.

Also it is the .so file that i am trying to load, counld this be part
of the problem, all the java documentation that i have seen talk about
.jar files and not .so
