[Hibernate-devel] input needed: exception messages

[Gavin_King/Cirrus%<CI...@ci...>]

Hi everyone,

Now that quite a few people are using hibernate, I'd like to know how easy
people are finding debugging/troubleshooting in their systems. In
particular are there common mistakes that are hard to track down? Are there
any error messages that are misleading or give too little information?
Would a more complex exception class hierarchy be useful (ie. would anyone
find it useful to catch subclasses of HibernateException)?

Slightly related to this: would there be any advantage in having a "proper"
approach to logging events inside the persistence layer? (Beyond the
present rudimentary approach of System.out.println() when
hibernate.debug>0) We could pretty quickly rip out all the printlns and
replace them with log4j, for example. But perhaps people are wishing they
could see other kinds of information altogether.

Any other related ideas?

Thanks

Gavin
