I am creating a jersey application using apache tomcat 7.0 and eclipse. I have created a dynamic web project in eclipse and have defined a resource file as:-
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
// Plain old Java Object it does not extend as class or implements
// an interface
// The class registers its methods for the HTTP GET request using the @GET annotation.
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML.
// The browser requests per default the HTML MIME type.
//Sets the path to base URL + /hello
@Path("/hello")
public class Hello {
// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
return "Hello Jersey";
}
// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)
public String sayXMLHello() {
return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
// This method is called if HTML is request
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello Jersey" + "</title>"
+ "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
}
}
web.xml file is also created as below-
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
Following jar files have been added to lib folder in web-inf and are also coming in directory structure in web-apps after war file is deployed.
The problem which is coming as soon as i start tomcat and war file is deployed following error is displayed:
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/de.vogella.jersey.first]] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:154) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:901) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:877) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:634) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:1074) at org.apache.catalina.startup.HostConfig$DeployWar.run(HostConfig.java:1858) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) Caused by: java.lang.NoClassDefFoundError: jersey/repackaged/com/google/common/base/Function at org.glassfish.jersey.internal.ServiceFinder.(ServiceFinder.java:165) at org.glassfish.jersey.servlet.internal.ServletContainerProviderFactory.getAllServletContainerProviders(ServletContainerProviderFactory.java:66) at org.glassfish.jersey.servlet.init.JerseyServletContainerInitializer.onStartup(JerseyServletContainerInitializer.java:132) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5444) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) ... 11 more Caused by: java.lang.ClassNotFoundException: jersey.repackaged.com.google.common.base.Function at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1702) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1547) ... 16 more
I have added following jars to lib folder:
**/de.vogella.jersey.first/WebContent/WEB-INF/lib/guava-16.0.1.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-client.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-common.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-container-servlet-core.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-container-servlet.jar
/de.vogella.jersey.first/WebContent/WEB-INF/lib/jersey-server.jar**
But still this error is coming, please tell me where i am going wrong.
