[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-3170) PersistentClass classname is not revealed in MappingException

PersistentClass classname is not revealed in MappingException ------------------------------------------------------------- Key: HHH-3170 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3170 Project: Hibernate3 Issue Type: Improvement Affects Versions: 3.2.x, 3.3.0.CR1 Reporter: Paul Benedict Assignee: Diego Plentz Attachments: SimpleValue.java A typical exception from bad configuration is: Caused by: org.hibernate.MappingException: Could not determine type for: java.util.Map, for columns: [org.hibernate.mapping.Column(name)] Recommendation: The "org.hibernate.cfg.Configuration" class should catch the exception and add the name of the offending PersistentClass. The class is held by the iterator. Line 1100 improvement: private void validate() throws MappingException { Iterator iter = classes.values().iterator(); while ( iter.hasNext() ) { PersistentClass pc = (PersistentClass) iter.next(); try { pc.validate( mapping ); } catch(MappingException e) { throw new MappingException(pc.getClassName(), e); } .... } Otherwise, I find it incredibly difficult to find the offending class without a step debugger.
