Stop that Jon! :) Seeing my name all over the CVS is rewarding enough.
It's the first time ever I contributed to an Open Source project, and it
feels really great.
OK, back to the buisness:

It doen't seem to help though. Here's another one: (same situation -
first hit under weblogic, after that works OK)
java.lang.NullPointerException
at Turbine.handleException(Turbine.java:507)
at Turbine.doGet(Turbine.java:370)

The matters are more complicated than I thought here.
I have a simple servlet - JDBCTest that allows me to connect to a driver/url
of my choice.
Consider these two scenarios:
* hit JDBCTest - dies with java.lang.ClassCircularityError:
com/sybase/jdbc2/timedio/SocketDbio
* hit JDBCTest - OK
* hit Turbine - dies with NPE (see above)
* hit Turbine - OK
any subseqent hits to Turbine work
* hit Turbine - dies with NPE (see above)
* hit Turbine - dies with java.lang.ClassCircularityError:
com/sybase/jdbc2/timedio/SocketDbio
* hit Turbine - dies with java.lang.NoClassDefFoundError:
org/apache/turbine/om/user/peer/TurbineUserPeer at
org.apache.turbine.om.user.TurbineUser.setUserName(TurbineUser.java:502)
any subsequent hits to Turbine fail with above Error
any hits to JDBCTest work, including the first one
What do you think about that? especially NCDF it the second scenario looks
weird...
And now the updated Turbine compatibility chart:
Linux / IBM JDK 1.3
------------------------------
Apache 1.3.9 + JServ 1.1 + MySQL 3.22 OK
Tomcat 3.1 + MySQL 3.22 OK
Tomcat 3.1 + Sybase ASE 11.9.2 OK
WebLogic 5.1+ MySQL 3.22 OK*
WebLogic 5.1+ weblogic.jdbc.pool over MySQL 3.22 OK*
WebLogic 5.1+ weblogic.jdbc.pool over Sybase ASE 11.9.2 OK*
WebLogic 5.1 + Sybase ASE 11.9.2 OK* **
Windows NT / Sun JDK 1.2.2
------------------------------------------
Tomcat 3.1 + MySQL 3.22 OK
* works, but there's NPE on the first hit issue
** works, but has some issues with initializing
