Normally weblogic 12c doesnt support jax-rs 2.0 but by the help of jax-rs shared library which comes with weblogic itself it is possible to upgrade jax-rs version from 1.1 to 2.0. The problem is library implementation is jersey 2.5 which doesnt satisfy my needs. I found a link about upgrading jersey version on weblogic which looks a lil bit complex. Is it enough to replace jersey jars 2.5 with my jersey version 2.13? Do i need to do anything else?
I have created a simple maven project to produce the war file with the 2.19 jersey shared library for weblogic.
I have tested it with weblogic 12.1.3
You can clone from here weblogic-jax-rs
After cloning run mvn package to produce the war and then deploy it to the server.
Of course you must specify the new implementation version in your weblogic.xml which is now 2.19
If you are not familiar with maven you can download the war file from here
As of weblogic 12.2.1 - there is jersey 2.21.1 bundled with it so no additional installations are required.
weblogic 12.2.1.1 comes with jersey 2.22.1
