Deploying Jersey based Restful webservice in Weblogic 12c

Question

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:

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

3. 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:specification-version>2.0</wls:specification-version> <wls:implementation-version>2.21</wls:implementation-version> <exact-match>false</exact-match> </wls:library-ref> 

4. Generated the web-service war file using the below pom.xml

  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.cts</groupId> <artifactId>WLRest</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>WLRest</name> <build> <finalName>WLRest</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.5.1</version> <inherited>true</inherited> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> </plugins> </build> <dependencyManagement> <dependencies> <dependency> <groupId>org.glassfish.jersey</groupId> <artifactId>jersey-bom</artifactId> <version>${jersey.version}</version> <type>pom</type> <scope>provided</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.glassfish.jersey.containers</groupId> <artifactId>jersey-container-servlet-core</artifactId> <version>${jersey.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.glassfish.jersey.media</groupId> <artifactId>jersey-media-moxy</artifactId> <version>${jersey.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.wordnik</groupId> <artifactId>swagger-core_2.10</artifactId> <version>1.3.11</version> <exclusions> <exclusion> <groupId>javax.ws.rs</groupId> <artifactId>jsr311-api</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <properties> <jersey.version>2.21</jersey.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> </project> 

And with the below we.xml entries:

<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,
     see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html -->
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <servlet>
        <servlet-name>Jersey Web Application</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>com.cts.WLRest</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Web Application</servlet-name>
        <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.

Answer 1

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:
