Did a lot of search, but no luck.
I'm trying to make a 'hello world' app which integrates Jersey and Google App Engine.
In Eclipse, I created a 'Web Application Project' and added Jersey JAR to the build path.
Then I modified web.xml and it looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>Jersey Web Application</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.example.myJersey</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey Web Application</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
In the package 'com.example.myJersey' I have HelloWorldResource.java, here is an excerpt:
// The Java class will be hosted at the URI path "/helloworld"
#Path("/helloworld")
public class HelloWorldResource {
// The Java method will process HTTP GET requests
#GET
// The Java method will produce content identified by the MIME Media
// type "text/plain"
#Produces("text/plain")
public String getClichedMessage() {
// Return some cliched textual content
return "Hello World";
}
}
When I click run, I get this error:

EDIT:
Maybe there is a misconfiguration in web.xml. Looks like Jetty doesn't like Jersey's servlet class.
I would appreciate any kind of help.
I recently put together a project template on GitHub combining Jersey and Guice for AppEngine. It may help to compare with a running app.
Jersey requires Java 1.6. Is this what the Google App Engine runs on? Maybe your Google App instance is configured to run on an earlier Java version.
Look at this:
http://code.google.com/p/googleappengine/wiki/WillItPlayInJava
Make sure that you run Jersey 1.5 and configure as required in the doc. Also, are you using other libraries? Those may create a classloading conflict?

I have a very simple Resource class that looks like below
package service;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
#Path("names")
public class NameService {
#Produces(MediaType.APPLICATION_XML)
#Path("name")
#GET
public String getName(#QueryParam(value="id")int id){
return "Nishanth";
}
}
I defined a custom application class ( extending ResourceConfig) to encapsulate this Resource class.
package application;
import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.server.ResourceConfig;
public class MyApp extends ResourceConfig{
public MyApp()
{
packages("service");
}
}
My web.xml looks like below. This is a servlet 3.0 web application in Eclipse meant to be deployed on Tomcat 7
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet>
<servlet-mapping>

</servlet-mapping>
</web-app>
My lib has the below jars added to application classpath.
I deploy the above application directly through Eclipse into a Tomcat 7.0 servlet container. I access the below URL
http://localhost:8080/RESTapp/res/names/name?id=2
and the browser shows the error below with response status 500

I know that the above error is thrown when the container is not able to find a servlet-class. I could be wrong.
Not sure what is going wrong here since as per Jersey API docs, Jersey container should add the servlet class when deployed this way in a Servlet 3.0 container.
I checked all over stack overflow and other forum posts but i could not find anything close to the issue i am facing now.
Any help is greatly appreciated.

There was the a problem with the EAR being created. I deleted the application, restarted the server and redeployed the application which solved it.
You need to add jar with Struts to your application. Build path is good in your development environment, but to run it must be somehow in the classpath during runtime. The easiest is as Steve C suggested - to add struts.jar to your WEB-INF/lib.
This kind of java.lang.ClassNotFoundException can manifest sometimes when a dependent class is not available.
Make sure that you application has access to the dependent jars as well, such as:
commons-beanutils
commons-digester
commons-logging
etc
I'm trying to publish a simple java web service using tomcat. Referring to below screenshot, I have HelloWorld.java which is service interface and its HelloWorldImpl.java implementation class.
Also I've created web.xml and sun-jaxws.xml.
When I right click the project, select Run As and then Run on Server, I get 404 error message as shown in bottom of screenshot.
The URL which internal browser tries to reach is http://localhost:8081/MySqlConnect/ where MySqlConnect is project name. Note that I'm using 8081 as port number.
I also tried http://localhost:8081/HelloWorld/hello, but it didn't worked.
I have also provided the code for all files below.
I'm not able to understand where am I going wrong? Any help appreciated.
HelloWorldImpl.java
package com.mycompany.service;
import javax.jws.WebService;
#WebService(endpointInterface = "com.mycompany.service.HelloWorld", serviceName = "HelloWorld")
public class HelloWorldImpl implements HelloWorld {
#Override
public String sayGreeting(String name) {
return "Greeting " + name + "!";
}

The correct url is http://localhost:8081/MySqlConnect/hello as MySqlConnect is the name of your context and hello the web service url.
Also its a webservice so to access it properly you can make a SOAP call.
But the root cause is your web application is not starting due to unable to find class javax.xml.ws.soap.AddressingFeature$Responses.
Have you added right dependencies? Search in those dependencies if this class exists. Response is a inner class of AddressingFeature.

I think I'm missing something really basic, but I don't know what. Can anyone help please?
I assume you are using eclipse so please check the setting of Default output folder. it should be inside WEB-INF/classes while compile project.
I encountered the same problem. The reason was that i created project using GPE (Google Plugin for Eclipse) and tried to follow GWT in action book. But my version of GPE creating a lot of staff insted of just basic project infrastructure. So, if you change your web.xml to
<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

everything should work fine.

Your .war was compiled under a newer JDK than the JRE that is available on the remote tomcat. Either install a matching JRE on the remote server or recompile your project with the correct version of the JDK.
This line should give you a clou:
java.lang.UnsupportedClassVersionError: com/shafer/server/server :
Unsupported major.minor version 51.0
(unable to load class com.shafer.server.server)
What is com.shafer.server.server? Check the versions of your libraries.
The UnsupportedClassVersionError means that the class was compiled with a more recent Java compiler than the one you are using in your runtime.
I don't know the version numbers by hearth, but you should probably use a JRE 6 or higher to run Tomcat.
