问题
I have upgraded my web application to JAX-RS 2.0.
The web application seems to work fine on Apache Tomcat. However, it does not get deployed on Weblogic 12c (or even 10.3.6).
I am not sure if there is a proper support by weblogic and I believe it requires some configuration and class loader filtering to override the default JAX-RS 1.1 implementation ?
Any idea how to achieve this and make my web application run on WLS 12c ?
回答1:
WebLogic 12c is Java EE 6 certified and so, implements JAX-RS 1.1. WebLogic plans to offer support for JAX-RS 2.0 in its next version 12.1.3 (as well a few other Java EE 7 APIs, but not all).
If you want to use JAX-RS 2.0 in current releases of WebLogic (12.1.1 and 12.1.2) you will have to deploy JAX-RS as you do with Tomcat, and tune weblogic.xml to isolate the classpath so it won't conflict with the JAX-RS 1.1 implementation.
For specifics on how to do this, please see documentation (of WebLogic 12.1.2): Updating the Version of Jersey JAX-RS RI
Update, Jan 4th, 2016
WebLogic 12.2.1, already released, is fully Java EE 7 certified.

WebLogic 12.1.3 will support JAX-RS 2.0 after registering Jersey 2.5.1 in the domain.
