SQLERRMC: java.lang.NullPointerException&#20;&#20;XJ001.U
     at
org.apache.derby.client.am.SQLExceptionFactory40.getSQLException(Unknown
Source)
     at org.apache.derby.client.am.SqlException.getSQLException(Unknown

More information is needed to tell the origin of the 
NullPointerException.  If you could print the entire exception chain, 
this could give more information.  Also, if the NPE occurs on the 
server, there is probably a stack trace in derby.log that could tell a 
bit more.

Can you please provide more info on what is causing the problem? Is
there a reproducible SQL script in IJ that can duplicate the problem?

thanks,
Mamta
