Sorry for late reply , but can you share your entity definition ? Which version of CouchDB are you using?

Anyhow thank you for the reply.. We actually solved the problem, I was missing the document id in the view to fetch user details. Fixed it by debugging the source files..
But I have another problem.. Am trying to connect both mysql and couchdb (2 persistence units) using spring's LocalContainerEntityManagerFactoryBean. But no success. I get the following exception.

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined: expected single matching bean but found 2: entityManagerFactorySQL,entityManagerFactoryCouch

Thanks in advance for any help!!.

Thanks for the support!
