I have developed a very small restful Web Service in eclipse using the "jersey" archetype.I was also successful in deploying that in tomcat. However, I am unable to deploy that in weblogic 12c. This is what I have tried so far:

  1. created a shared library containing the jersey libraries as I have seen in one of the post. This is my pom.xml which generates the shared library containing the required manifest file:

  1. Deployed the war in weblogic server as a "library"

  2. Added a weblogic.xml under WEB-INF folder in my webservice application with the following entry: http://xmlns.oracle.com/weblogic/weblogic-web-app/1.7/weblogic-web-app.xsd">

        <wls:library-ref>
        <wls:library-name>jax-rs</wls:library-name>

        <wls:implementation-version>2.21</wls:implementation-version>
         <exact-match>false</exact-match>
    </wls:library-ref>
  3. Generated the web-service war file using the below pom.xml
      <project xmlns="http://maven.apache.org/POM/4.0.0"

And with the below we.xml entries:

        <url-pattern>/webapi/*</url-pattern>
    </servlet-mapping>
</web-app>

Now, when I am trying to deploy the the war in weblogic, it is throwing the following exception:

An error occurred during activation of changes, please see the log for details.

I have also used maven dependency tree and Jshades to confirm there is no conflict between different version of jars. Any help or pointer on this will be greatly appreciated.

This is beacause Weblogic puts its own jars for some libraries. In this case it's an older version of jax-rs. You can see that this method is new to JAX-RS 2:

Application javadoc

In order to enforce your packages, you need to configure prefer application packages in WLS:

prefer-application-packages

You also need to understand this:
