You need to have your shared libraries accessible. In other words, you need
to set your LD_LIBRARY_PATH environment variable to point to the directory
where the shared libraries are kept on disk. Then you can make them
accessible in two one of two ways:
1) wrapper.env.copy=LD_LIBRARY_PATH
2) wrapper.env.copyall=true
Hope this helps.

> JServ installation: Stronghold 2.4/Apache 1.30, JServ 1.0b2, Oracle 7 JDBC
