Subject RE: Interbase/Firebird prepare-testdb problem

Hi David,

The following files were missing from the torque-3.0.jar for some reason:


[TORQUE-GUYS] Is there a reason for this?

The SQL seemed pretty straight forward so I just placed slightly modified
copies of the postgres version of those files on the classpath and managed
to get past the 'project-sql-classpath' target in OJB's build.xml.

However, then in the 'project-insert-sql' target I got the error at the
bottom of this email (even though firebirdsql.jar is in the lib directory).
The code does a Class.forName() on the database driver and then calls
newInstance() on the returned class, this isn't working for some reason.

After that I tried using using the ojbcore-schema.sql to insert the default
required tables into the firebird database skipping the test torque stuff.
However, I got an error when doing that: "GDS Exception. unsuccessful
metadata update key size too big for index RDB$PRIMARY5".  After a good deal
of searching it seems that the primary key should not be greater that 256
bytes in Firebird and less than 200 if the PK is a composite.  I changed the
OJB_HL_SEQ TABLENAME column size to 128 (with FIELDNAME column with size 70)
and finally creating the table worked.  However, I don't know whether this
is going to mess up OJB's sequence manager.  Did you have any trouble with
