[jboss-user] [JBoss Web Services] - JPA JAX-WS LazyinitializingException during marshalling of collections

Hi all, The scenario is : jboss 4.2.2, EJB3 entity that describes the model, EJB session deployed as web service. The problem is that when a client invokes a method of the web service that returns an entity (that references a collection) receave a LazyinitializingException. This is due to the marshalling operation that is executed after jpa session closing. To solve this I would implement long session pattern with a "web service transaction". I can I implement it? Thanks in advance Devone
