Upon running my GWT/GAE (App Engine) application the app throws this error:

ClassNotFoundException: org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap

Here is the POM.xml

<dependency>
  <groupId>org.jboss.resteasy</groupId>
  <artifactId>resteasy-jaxrs</artifactId>
  <version>${resteasy.version}</version>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxb-provider</artifactId>
    <version>${resteasy.version}</version>
</dependency>

And here is the log:

java.lang.ClassNotFoundException: org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at com.google.appengine.tools.development.IsolatedAppClassLoader.loadClass(IsolatedAppClassLoader.java:213) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) at org.mortbay.jetty.handler.ContextHandler.loadClass(ContextHandler.java:1101) at org.mortbay.jetty.webapp.WebXmlConfiguration.initListener(WebXmlConfiguration.java:630) at org.mortbay.jetty.webapp.WebXmlConfiguration.initWebXmlElement(WebXmlConfiguration.java:368) at org.mortbay.jetty.webapp.WebXmlConfiguration.initialize(WebXmlConfiguration.java:289) at org.mortbay.jetty.webapp.WebXmlConfiguration.configure(WebXmlConfiguration.java:222) at org.mortbay.jetty.webapp.WebXmlConfiguration.configureWebApp(WebXmlConfiguration.java:180) at org.mortbay.jetty.webapp.WebAppContext.startContext(WebAppContext.java:1247) at org.mortbay.jetty.handler.ContextHandler.doStart(ContextHandler.java:517) at org.mortbay.jetty.webapp.WebAppContext.doStart(WebAppContext.java:467) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerWrapper.doStart(HandlerWrapper.java:130) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at org.mortbay.jetty.handler.HandlerWrapper.doStart(HandlerWrapper.java:130) at org.mortbay.jetty.Server.doStart(Server.java:224) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:50) at com.google.appengine.tools.development.JettyContainerService.startContainer(JettyContainerService.java:205) at com.google.appengine.tools.development.AbstractContainerService.startup(AbstractContainerService.java:232) at com.google.appengine.tools.development.DevAppServerImpl.start(DevAppServerImpl.java:157) at com.google.appengine.tools.development.gwt.AppEngineLauncher.start(AppEngineLauncher.java:97) at com.google.gwt.dev.DevMode.doStartUpServer(DevMode.java:509) at com.google.gwt.dev.DevModeBase.startUp(DevModeBase.java:1093) at com.google.gwt.dev.DevModeBase.run(DevModeBase.java:836) at com.google.gwt.dev.DevMode.main(DevMode.java:311)

What could be missing?

Update:

Anyone can share their web.xml that worked for RestEasy + GAE

Which version of resteasy-jaxrs jar are u using and check for version 2.3.0.GA or higher. – appbootup
version 2.3.5.Final Apparently, the JARS are not being copied into the WEB-INF/lib folder – quarks

The exception indicates the classes are not there.

Ensure that resteasy-jaxrs are copied into your WEB-INF/lib and also ensure that your version is 2.3.0.GA or higher.

If your project is maven base project then run

mvn eclipse:clean

mvn eclipse:eclipse

it will add jar from m2 repo to lib folder then redeploy webapp and restart tomcat/server

Please check that

  1. You are not pointing to a JRE, should be a JDK.
  2. Remove and Add your server. Then run the application again.
