no persistent classes found for query class

Question

Hello friends,

I am creating web application using zkoss 5.0.4, Spring 3.0.3, Hibernate 3 and JpA 1.0 with JBOSS 5.1 GA(with jdk support).

project compiles fine with JBOSS. But it seems that persitence is not applying for some reason.

When I run an application in console it gives following

10:07:35,265 WARN [QuerySplitter] no persistent classes found for query class: from org.zkforge.zktodo2.Reminder

Following is list of jar files that I am using in /WEB-INF/lib directory.

Sorry for the bad formating of code.. I do no know how best format code in this editor.

Can any one help me regarding the matter.

Please let me know if you need anything else from my side.

Thanks.

Answer 1

The log file has the following:

10:06:41,375 WARN [Ejb3Configuration] Persistence

provider caller does not implement the EJB3 spec correctly. PersistenceUnitInfo.getNewTempClassLoader() is null. 10:06:41,515 INFO [AnnotationBinder] Binding entity from annotated class: org.zkforge.zktodo2.Reminder

I think you should relook at Reminder class.

Answer 2

Hello friends,

I added following in my persistence file and it started fine.

< class >org.zkforge.zktodo2.Reminder< / class >

adding above line created the table in database and persistence error gone.

I do not know why do we need to add it.

is there any reason?

Shouldn't Spring or Hibernate should get that thing from Reminder.java file?

If anyone has any idea. Please let me know.

Thanks.
