Anybody have any ideas. Win XP, ServletExec 5.0 , Db2 Client 8.1
I have uninstalled, cleaned my class path and I get the same error after reinstalling.

java.lang.NullPointerException
at COM.ibm.db2.jdbc.app.SQLExceptionGenerator.throw_SQLException(Unknown Source)
at COM.ibm.db2.jdbc.app.SQLExceptionGenerator.check_return_code(Unknown Source)
at COM.ibm.db2.jdbc.app.DB2Connection.connect(Unknown Source)
at COM.ibm.db2.jdbc.app.DB2Connection.(Unknown Source)
at COM.ibm.db2.jdbc.app.DB2Driver.connect(Unknown Source)
at java.sql.DriverManager.getConnection(DriverManager.java:525)
at java.sql.DriverManager.getConnection(DriverManager.java:171)

I have put a sys out in my code and it passes the correct connection string. It seems that between the DriverManager and the App driver, the connection string goes away. Any body seen anything like this before.

I'll pull together some of the code that is used. More info: the servlet uses connection pooling, and command line java programs that access the db via the same driver work fine.
