Java Database Connectivity (JDBC)

I'm having some issues configuring Tomcat with a 10g JDBC driver under Linux using the OCI thick client. When I attempt to get a database connection I get the following:

java.lang.UnsatisfiedLinkError: no ocijdbc10 in java.library.path
java.lang.ClassLoader.loadLibrary(Unknown Source)
java.lang.Runtime.loadLibrary0(Unknown Source)

....

Now I've seen other instances of the above and they basically come down to making sure that the ojdbc14.jar file is in my classpath, and I thought I had that covered.

Here's everything I've done:

added ojdbc14.jar to $TOMCAT_HOME/common/endorsed
added ojdbc14.jar to $TOMCAT_HOME/common/lib

verified that ORACLE_HOME is defined: /app/oracle/product/10.1.0/client_1
verified that LD_LIBRARY_PATH is defined: /app/oracle/product/10.1.0/client_1/lib

added the following to the java commandline for Tomcat:

-Djava.library.path="$ORACLE_HOME"

the above -Djava.library.path didn't work so made the following change (which still didn't work)
-Djava.library.path="$ORACLE_HOME"/lib

my PATH variable includes both $ORACLE_HOME and $ORACLE_HOME/lib

echo $PATH:
/app/oracle/product/10.1.0/client_1:/app/oracle/product/10.1.0/client_1/lib

I have no idea what else I am missing or if my Oracle client installation is just hosed.

Any assistance would be appreciated.
