Neither am I and I never will be. For some reason, I simply loathe Java.    

Having said that, the usual cause (in my code anyway) is simply having a semi-colon in the SQL statement as in something like this statement.parse('select stuff from dual ; ');

The semi-colon usually gives the problem.

I shouldn't think that that's a problem as it is perfectly valid - especially as the table is already created (isn't it ?) in the database.

If you can recreate the problem at will, shove a 10046 trace on the session (or use DBMS_SUPPORT.START_TRACE_IN_SESSION(sid, serial#, false,false) and scan the resulting trace file (after you recreate the problem) for an ERROR line. That's the cursor and statement that is giving you grief. You'll probably find it fails on the PARSE phase. DBMS_SUPPORT.STOP_TARCE_IN_SESSION(sid,serial#) turns tracing off - if the session hasn't ended by then. (connect as sys and start ?/rdbms/admin/dbsmsupp.sql to install it for SYS use only.)

HTH Cheers,
