I am trying to build a async REST client but getting following error in IBM WebSphere 8.5, java.lang.RuntimeException: java.lang.NoClassDefFoundError: javax/ws/rs/client/ClientBuilder

While building ClientBuilder object. I tried to search everywhere but solution is provided for other application servers not for IBM WebSphere. When I decompiled ClientBuilder class it expect the property JAXRS_DEFAULT_CLIENT_BUILDER = "org.glassfish.jersey.client.JerseyClientBuilder";

but what is the value of implementation class/property for WebSphere?

Code I am trying to run, 

ClientBuilder cb = ClientBuilder.newBuilder();   // Exception occurs at this line
Client client =   cb.build(); 
WebTarget target  = client.target(URL);
Future<Response> future = target.request(MediaType.APPLICATION_XML).async().
post(Entity.entity(notifications, MediaType.APPLICATION_XML));
Response response  = future.get(5, TimeUnit.SECONDS);
if(response.getStatus() == SUCCESS) {
        respStatus = SUCCESS;
}

Am I missing some configuration? or property setting?

Note: I have added javax.ws.rs-api-2.0-m10.jar on classpath.

WebSphere provides jaxrs-1.1 implementation based on Wink, so they will conflict with library you provided. You will either need to disable default implementation and use your own, or create Wink client.

  • Thanks @Gas. I rewrote client with Apache Wink as we have multiple applications deployed on single server. Configruation changes in server will impact other applications as well so went with Wink approach. – SandyStack Dec 03 '14 at 20:05
