Null pointer exception in JDBC API tests

[Ajay Gupta <aj...@gmail.com>]

Hi,
I am trying to run JDBCAPI tests using derby trunk with DB2 type 4
drivers(com.ibm.db2.jcc.DB2Driver). But in first statement 
ij.startJBMS(), I am getting null pointer exception. These test cases
are working correctly with type 2
driver(COM.ibm.db2.jdbc.app.DB2Driver).

Could some one pls advice on this ?

regards,
ajay

Hi Ajay,
 Following is what Dan Debrunner replied to your earlier mail on null

Wow, that's impressive, using the COM.ibm.db2.jdbc.app.DB2Driver driver
to connect to Derby, you are probably the first to try that!

How are you running these tests using these drivers?

If you are using the Derby test harness then the jdbcapi suite runs
using Derby's own embedded driver (org.apache.derby.jdbc.EmbeddedDriver)
and some of those tests run in the suites that use client server mode
and the client drivers.

derbynetclientmats - org.apache.derby.jdbc.ClientDriver
derbynetmats - com.ibm.db2.jcc.DB2Driver
