Question

I have a spring MVC web application, to which we integrate a spring-jersy REST service for some utility functionality.The application we deployed in tomcat 7.x and it works fine. But when we deploy it in Weblogic server, the web application is working fine, but when this application contac the integrated REST service, the following exception happened

We also tried to hit the integrated REST service from browser- same error! But it would work perfectly in tomcat. What might be the problem. Please help...

Answer 1

My success story :

we are migrating from weblogic 10.3.6(Application using using jersey 1.17) to weblogic 12C. When build of 10.3.6 is deployed on 12C, we were getting following stack trace.

Root cause of ServletException. java.lang.AbstractMethodError: uri at javax.ws.rs.core.UriBuilder.fromUri(UriBuilder.java:119) at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:662) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820)

After searching for a week in Google for possible solutions and suggestions, nothing worked for me. Following things helped me for sorting out the problem.

1. Removed all jersey related jars from build. Since weblogic 12C has built in library.
2. updated web.xml with Glassfish servlet instead of 1.7 jersey servlet.

OLD entry: com.sun.jersey.spi.container.servlet.ServletContainer

Replaced with entry : org.glassfish.jersey.servlet.ServletContainer

3. Shutdown weblogic server, deleted tmp & cache directories of weblogic node ( this was Critical step)
4. Deployed build latest
5. restarted weblogic 12c servers.
6. REST services started working fine.

FYI : NO other code changes done. we already had MyApplication.java file which has REST service implementation class like below.

 public class MyApplication extends Application { @Override public Set<Class<?>> getClasses() { final Set<Class<?>> classes = new HashSet<Class<?>>(); classes.add(com.sri.test.SriRestService.class); return classes; } }
