Hi Ryan,
I'm not exactly sure what you are doing here. Are you trying to compile
MapServerTest.java ? And does it require mapscript.jar for it to compile
correctly? First, you should define the full path to the mapscript.jar
file to avoid confusion, and next, after the compile, you should check
that there is a file called MapServerTest.class in the same directory,
if it does compile correctly (i.e. without errors).
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");

How are you running it in Tomcat? Have you defined a context, and does
it work properly? You should test with a plain web page first to verify
that the URL for the context really works.
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.

IIRC libraries that are placed inside <tomcat-directory>/common/lib are
available to all servlets. I'm not clear though on whether this is still
the behaviour in Tomcat 5.5. But the thing is, if you *only* need to use
the library for your servlet (presumably MapServerTest), you should
place the library in the lib directory of your servlet context.
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
