Called by JcrTemplate.execute(org.springframework.extensions.jcr.JcrCallback, boolean) within an active JCR javax.jcr.JCRSession. It is not responsible for logging out of the Session or handling transactions. Allows for returning a result object created within the callback, i.e. a domain object or a collection of domain objects. A thrown RuntimeException is treated as an application exeception; it is propagated to the caller of the template.

Throws:

java.io.IOException

javax.jcr.RepositoryException
