Jpa entities over a JAX WS services without infinite loop
How can I send JPA generated entities over an JAX WS web service without getting the an XML infinite cycle exception because of the cycle of references in those entities? Any idea? I found this MOXy that can do it...partially. But i already have the entities generated and to manually add XmlTransient and such annotations to each of them it's crazy. Do you have any other idea how to do it? Thanks!

Bean Validation with JPA 1.0 - Antonio's Blog
For those of you who still donâ€™t know Bean Validation, you should check the JSR 303 and the documentation of the reference implementation Hibernate Validator. In fact, like many other JSRs, Hibernate Validator existed on its own for quite a long time as an open source project (until version 3.1.x) and then got specified under the JSR 303 and became the reference implementation from its version 4.x
