hi!

when you build a SessionFactory for a Database that does not exist,
an exception is thrown and logged.
however, i can NOT catch that exception.
what am i doing wrong?

my code:

try {
Configuration cfg = HibernateSessionPool.buildConfiguration(ds);
cfg.setProperty("hibernate.hbm2ddl.auto","create");
SessionFactory sf = cfg.buildSessionFactory();
} catch (Exception ex) {
// Make sure you log the exception, as it might be swallowed
logger.severe("Initial SessionFactory creation failed.");
throw new ExceptionInInitializerError(ex);
}

the stack trace says the exception is thrown in the last line of the try
block. however, the catch block is never entered. i have
no chance to catch the exception...

any clue?


Hibernate version:
3.0.5

Full stack trace of any exception that occurs:

Name and version of the database you are using:
MySQL

hbm2ddl.auto swallows any exceptions to allow your test app to continue.

If you want to catch the exception then call schemaexport manually via code.

hi!

i have the same problem again.
i called schemaexport manually, not through hbm2ddl.
in my configuration, i never set hbm2ddl to any value.

however, an exception is still logged in the console but i cannot
catch it in code.

i do:

SchemaExport se = new SchemaExport(cfg);
se.create(false, true);

and get a
2005-11-20 10:18:58,265 ERROR SchemaExport:schema export unsuccessful
java.sql.SQLException: No suitable driver
at java.sql.DriverManager.getConnection(DriverManager.java:545)
at java.sql.DriverManager.getConnection(DriverManager.java:140)

SchemaExport.create is declared void, so i can't get any info out of it.


do i have to explicity set anything else in my config
in order to make exceptions catchable?

thanks in advance

schemaexport.getExceptions()

or

schemeexport.setHaltOnError()

thank you very much for the really quick reply!

i'll try these.

i see you're on the hibernate team.
i suppose you have a good reason for not throwing the exception...
anyway, it would be helpful if you displayed a little note
along with the stacktrace of the exception that says how it
could still be caught or received later.

cheers again
