Body
copied!<p>I have a Java webservice running in Tomcat 6 which accepts JSON input. I am trying to use Jackson ObjectMapper to parse the input json. But when initializing the ObjectMapper object I am getting this error</p> <pre><code>16:08:13,616 ERROR [[jersey]] Servlet.service() for servlet jersey threw exception java.lang.VerifyError: Cannot inherit from final class at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:2733) at org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:1124) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1612) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1491) at com.test.project.offline.ws.WsApiResource.updateData(WsApiResource.java:169) ....... </code></pre> <p>At line 169 I have this <code>ObjectMapper mapper = new ObjectMapper();</code> </p> <p>When calling com.test.project.offline.ws.WsApiResource.updateData() method locally in a unit test it works without any error.</p> <p>Kindly help me in fixing this. I am using Jackson 1.8.4 and tomcat 6. </p> <p>UPDATE: Fixed the issue. Problem was a different version of jackson in the dependency tree. Excluding it fixed the problem.</p>
