Subject [jira] Commented: (CXF-3022) Integrating Spring 3 + GenericDAO (Don't repeat the DAO!) + CXF JAX-RS (JAXB Databinding) with a Generic Service Interface
Date Fri, 08 Oct 2010 11:28:31 GMT

    [ https://issues.apache.org/jira/browse/CXF-3022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12919244#action_12919244
] 

Benson Margulies commented on CXF-3022:
---------------------------------------

As I recall, I was the guy who originally trucked around the JAX-RS code trying to wire up
all the additional reflection needed to make generic work (when it was possible). The intent
of the spec was somewhat unclear to me as to what they expected to work, given type erasure.

Given a clear test case I can eventually find some time to help Sergey with this.

> Hello everyone,
> I'm trying to use a generic interface implementation as a JAX-RS service in order to
accomplish basic rest operations for all model data (in the same way that the pattern [GenericDAO|http://www.ibm.com/developerworks/java/library/j-genericdao.html].
