CXF problem on deployment of camel 2.21.0 spring boot1.5.9 on weblogic 12

[Jessie Ding]

Hi

I have developed a camel springboot project and it works fine standalone with 
Cxf and Tomcat or Jetty servlet.
But I met the following problems when I tried to deploy the project on 
Weblogic. It seems the cxf related jars might have problem with Weblogic jars.
Here is the similar problem on the web: 
https://stackoverflow.com/questions/47650275/spring-boot-camel-cxf-on-weblogic-12c-java-lang-noclassdeffounderror-javax?rq=1

I have spring boot 1.5.9 and cxf 3.2.1 and weblogic 12. I have cxfendpoints for 
soap and restful WS. When I deployed on the weblogic:
I got the same error msg: java.lang.NoClassDefFoundError: 
javax/cache/configuration/Configuration

I don't think I have to add javax.cache jar as I really don't use it.
I don't have web.xml but I defined CxfServlet in Java code.

public SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
   return builder.sources(SpringBootCDA09TrxnApplication.class);
}


@Bean
public ServletRegistrationBean servletRegistrationBean() {
    CXFServlet servlet = new CXFServlet();
    ServletRegistrationBean bean = new ServletRegistrationBean(servlet, 
"/service/*");
    bean.setLoadOnStartup(0);
    return bean;
}

Here is my weblogic.xml
<wls:container-descriptor>
        <wls:prefer-application-packages>
            <wls:package-name>org.slf4j.*</wls:package-name>
        </wls:prefer-application-packages>
    </wls:container-descriptor>



Following the suggestions from the web, I tried to remove rs-api.jar from 
camel-cxf but the problem still exists.

In my Pom, I corrected by doing


<dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-cxf-starter</artifactId>
       <version>2.21.0</version>
     <exclusions>
        <exclusion>
            <groupId>javax.ws.rs</groupId>
            <artifactId>javax.ws.rs-api</artifactId>
        </exclusion>
    </exclusions>
  </dependency>



   <dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
     <version>3.2.1</version>
         <exclusions>
             <exclusion>
                 <groupId>javax.ws.rs</groupId>
                 <artifactId>javax.ws.rs-api</artifactId>
             </exclusion>

         </exclusions>
</dependency>


Thanks a lot!
