Moving to Tomcat 6, Oracle 11g - getting weird exception

Question

Hello,
I am having a problem that I can't seem to get past:
java.lang.UnsatisfiedLinkError: oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber()I
     at oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber(Native Method)
     at oracle.jdbc.driver.T2CConnection$1.run(T2CConnection.java:3536)
     at java.security.AccessController.doPrivileged(Native Method)
     at oracle.jdbc.driver.T2CConnection.loadNativeLibrary(T2CConnection.java:3531)
     at oracle.jdbc.driver.T2CConnection.logon(T2CConnection.java:266)
     at oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:536)
     at oracle.jdbc.driver.T2CConnection.<init>(T2CConnection.java:162)
     at oracle.jdbc.driver.T2CDriverExtension.getConnection(T2CDriverExtension.java:53)
     at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:521)
     at java.sql.DriverManager.getConnection(Unknown Source)
     at java.sql.DriverManager.getConnection(Unknown Source)
     at com.rhs.db.conn.ConnectionOra.useOCIDriver(ConnectionOra.java:82)
The code, below, worked against Oracle 10g and Tomcat 5.5:
               try {
               DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
               _driverLoaded = true;
          } catch (Exception e) {
          deflog.error(e);
               _conn = DriverManager.getConnection("jdbc:oracle:oci:@orcl", login, pwd);
I have included ojdbc6.jar in Tomcat's "lib" directory. Am I just missing something dumb?
Thanks,
Jerry

Right it's blowing up on what looks like trying to get metadata about the library.
It's just loading the dll that came with 11g. I would think that if it were the wrong dll, that this would be a well known issue, right?
If I remove the library altogether, it complains about simply not being able to find the dll (obviously). If I use a jar ojdbc6.jar targeted at 10g, it complains about 10's dll not being there, which also makes sense.
My jvm is the latest (installed a couple of days ago).
A Google search of this particular failure yields pretty much 0 useful results, so I'm hoping someone can shed light on the problem, in general, and what one might do, in general, to fix it....perhaps a Java master employed by Oracle? :)
Ah well, I'm about to abandon this approach, I don't have time to monkey around with expensive databases that are clunky to upgrade (read almost completely different between versions) and have poor oob tool support. Oracle has cost our company more money than it's made us, that's for sure.
