Method Detail

doInJCR

T doInJCR(JCRSessionWrapper session)

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 exception; it is propagated to the caller of the template.

Parameters:

session - session passed by the JCRTemplate

Returns:

a result object returned by the action, or null

Throws:

javax.jcr.RepositoryException - in case of JCR errors
