Coexistence of JAX-RS 2.0 with JAX-RS 1.1

WebSphere Application Server traditional version 9 supports both Java API for RESTful Web Services (JAX-RS) 2.0 and JAX-RS 1.1 features. In version 9 and its later versions, we can switch among different JAX-RS providers.

The default JAX-RS provider on WAS traditional version 9 is Apache CXF-based JAX-RS 2.0. We can also switch to Apache Wink-based JAX-RS 1.1 either using command prompt or administrative console. Meanwhile, to help you bundle our own restful implementation in the application, the version 9 also provides support only for JAX-RS specification compresses.

Therefore, we can choose from the following JAX-RS providers based on our needs:

JAX-RS 2.0

Provides full support for JAX-RS 2.0.

JAX-RS 1.1

Provides full support for JAX-RS 1.1.

1.1 spec

Provides support only for JAX-RS 1.1 specification compress. We need to package the JAX-RS 1.1 specification implementations in the applications.

2.0 spec

Provides support only for JAX-RS 2.0 specification compress. We need to package the JAX-RS 1.1 specification implementations in the applications.
