[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-1042) Make DocHelper robust against failing buildSettings()

[Arnout Engelen (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HBX-1042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39092#action_39092 ] 

Arnout Engelen commented on HBX-1042:
-------------------------------------

So buildSettings() should be OK to call. However, in my case it is not OK to call (as it produces the stacktrace pasted at 02/Mar/08).

Is this a bug in Spring (LocalDataSourceConnectionProvider.configure() throwing a HibernateException), or should Hibernate not be calling LocalDataSourceConnectionProvider.configure()?

The issue still exists using Spring 3.x.

> DocHelper calls cfg.buildSettings(). to get the Dialect, default catalog name and default schema name.
> However, cfg.buildSettings() may fail with a HibernateException (example below). 
> It would be nice to have DocHelper handle this more gracefully. Attached is a simple patch that does this.
> (background: I'd like to use the Configuration I'm getting from a Spring LocalSessionFactoryBean, which after initial creation leaves its LocalDataSourceConnectionProvider in a state that yiels a HibernateException when calling 'configure()' on it, which buildSettings() does. Because of this issue, I cannot use the DocExporter for my Spring-based hibernate configurations)
