WebLogic 9.2: Oracle: Can longer connect with a Good Data Source

Question

Hi;
I have WebLogic 9.2 set up on my computer as a development tool. Yesterday I was able to connect to the test database on our test server with the JNDI/Database resource "abc" just fine.
For some reason, it simply stopped working this morning.
I got this error message when trying to connect with the webapp I use:
*+<Jul 28, 2011 4:48:14 PM EDT> <Notice> <Stdout> <000000> <Exception in getPersonIdByEmail(String emailAddress) - statementDB14>+*
+java.sql.SQLException: Cannot obtain connection: driverURL = jdbc:weblogic:pool:nsd, props = {EmulateTwoPhaseCommit=false, connectionPoolID=abc, jdbcTxDataSourcourceName=abc}.+*

I got this error message when using a Test JSP I have for doing a simple database connection using that Database Resource ( "abc")

Any ideas on how I can fix whatever is wrong?
Thanks in advance

Hi Joe;
I appreciate you taking time to answer my question.
By client do you mean my JRE? I one JRE set in my JAVA_HOME, and two in the weblogic install. How can I tell which is WebLogic using? So, you are basically saying make sure my Oracle JDBC drivers wherever they are in WebLogic should match what I have in my JRE?
I'll give that a shot when I get into work tomorrow.
I am puzzled because it has been working fine for weeks and I haven't changed anything.
