Read a CLOB data from an Oracle table and INSERT it into a BYTEA column in Postgres using jdbc?

Hi,
Im reading from an Oracle table and inserting the values to a postgres table thro' jdbc. Everything works fine except for the BLOB data in Oracle.

My code snippet ...

while (rs1.next())
{
for (int m=1;m<=colCount;m++)
{
pstmt.setObject(m, rs1.getObject(m));
}
pstmt.executeUpdate();
connection2.commit();
System.out.println("DONE");
}

This inserts the data into teh postgres table but gives this error for a BLOB datatype....
Exception in thread "main" org.postgresql.util.PSQLException: ERROR: column "columnXXX" is of type bytea but expression is of type bigint

Any thoughts?

Thanks
Sharmila
