Mike, Thank you for your response. I have tried to place my shared object files into /usr/local/lib which is in the LD_LIBRARY_PATH environment variable for my tomcat config.
When I place my class files in $CATALINA_BASE/common/classes, the function works correctly ( library is found ), but only once ( because the Native code cannot be loaded more than once in the JVM, I suppose ). When I place my class files in $CATALINA_BASE/shared/classes, which is what the docs explain is appropriate for resolving this issue, the class cannot be found. Is anyone else having trouble loading classes from $CATALINA_BASE/shared/classes? Thanks again.

This is an uneducated guess, but worth a try.
