NullPointerException during logon

322340Jul 12 2004 — edited Jul 12 2004
Hi, I am trying to connect to Oracle 9.2.0.4 with the thin 9.2.0.3 drivers with Java HotSpot(TM) Server VM (build 1.4.1_01-b01, mixed mode) on Linux, and I get this exception when I try to connect to the db: 
java.lang.NullPointerException
        at oracle.jdbc.ttc7.O3log.marshal(O3log.java:612)
        at oracle.jdbc.ttc7.TTC7Protocol.logon(TTC7Protocol.java:258)
        at oracle.jdbc.driver.OracleConnection.<init>(OracleConnection.java:360)
        at oracle.jdbc.driver.OracleDriver.getConnectionInstance(OracleDriver.java:521)
        at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:325)
        at java.sql.DriverManager.getConnection(DriverManager.java:512)
        at java.sql.DriverManager.getConnection(DriverManager.java:171)
< my code >
In my code, I'm calling 
java.sql.DriverManager.getConnection( jdbcUrl, user, password );
The weird thing is that my code works for all of my apps but one. I'm wondering what this error indicates; I've check my three variables to make sure they're not null.. and I don't really know where else to look.

Well, I replacing the driver libraries with some older 9iRelease 1 drivers I have, and this problem has gone away. I still don't know what might have caused it - but I would like to be able to update them at some time.
