Failure to detect dialect because of a failure to obtain connection (HHH00342) should show connection failure exception ----------------------------------------------------------------------------------------------------------------------- Key: HHH-6575 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6575 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 4.0.0.Beta5 Reporter: Mike Youngstrom I recently upgraded to Hibernate 4 Beta 5 and found it much harder to debug connection errors. My application depends upon Dialect detection and when my app cannot connect to the database I get the following warning with no stacktrace: JdbcServicesImpl: HHH00342:Could not obtain connection to query metadata : Exception occurred while getting connection: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource I then get a null dialect error because obviously the dialect couldn't be detected and I have no idea of it is a bad password or anything. I think the Warning above should also display the connection error stack trace like it used to in 3.x. Or at the very least an additional "DEBUG" level message should be logged with the full connection error stacktrace. -- This message is automatically generated by JIRA.
