I have an Entity named TrainingMstr. I have removed some fields from the table and updated the entity too. But I'm still getting the following error:

Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-0] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.IntegrityException

Descriptor Exceptions:

Exception [EclipseLink-59] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.DescriptorException Exception Description: The instance variable [trngRevNo] is not defined in the domain class [com.discusit.trims.entity.TrainingMstr], or it is not accessible. Internal Exception: java.lang.NoSuchFieldException: trngRevNo Mapping: org.eclipse.persistence.mappings.DirectToFieldMapping[trngRevNo-->trimsdev.trimsdev.training_mstr.trng_rev_no] Descriptor: RelationalDescriptor(com.discusit.trims.entity.TrainingMstr -->

I have removed trngRevNo variable from the database and then updated the entity. Still getting the error while deploying the application.

Can anyone please help me...???

Hi Maulik,

I suppose you are getting this issue while deployment and therefore you can try removing all folders and sub-folders in "work" folder of the server and deploy again with latest changes.

Thanks and Regards,

Check if you are using an orm.xml file to map the attribute. It may need to be updated.

Also try restarting your server if you have not done so, and ensure you don't have the class on the classpath twice somehow.
