Running a RESTlet Tutorial, I'm receiving java.lang.NoClassDefFoundError

Question

I'm trying to run the first server tutorial on RESTlet docs but i'm getting errors even though i added the jars to my classpath. I added org.restlet.jar and org.restlet.ext.*

The code for the server is :

package test;

import org.restlet.Server;
import org.restlet.data.Protocol;
import org.restlet.resource.Get;
import org.restlet.resource.ServerResource;

public class Test extends ServerResource {  

    public static void main(String[] args) throws Exception {  
        // Create the HTTP server and listen on port 8182  
        new Server(Protocol.HTTP, 8182, Test.class).start();  
    }  

    @Get  
    public String toString() {  
        return "hello, world";  
    }  

}

And the errors i'm getting are:

WARNING: No available server connector supports the required protocols: 'HTTP' . Please add the JAR of a matching connector to your classpath.

What am I missing?

Mokpo

I got these errors too, because I was trying to run the packaged jar file with java -jar myprogram.jar and I wasn't telling maven in the pom.xml file to stuff all the dependencies into the jar file. After I did, the "NoClassDefFoundErrors" were solved. The solution concept was to instruct maven to package the dependencies in with the compiled jar: #1729554 – Biota

Answer 1

It was Eclipse problem, i had to remove all the jars and only add org.restlet.jar and also clean the project. After i did that everything worked as expected.

Mokpo

Thanks, just ran into the same problem and you saved me a lot of work. – Fuzzy

Answer 2

Thanks. I was also having the same problem in NetBeans IDE. I removed "org.restlet.ext.httpclient-2.1m1.jar" file from the project lib and no errors since then.

Answer 3

Just to update that, from the latest restlet-jee-2.0.10/lib folder only copy the org.restlet.ext.servlet.jar and org.restlet.jar. That solved the problem in Eclipse.

Answer 4

After running /selectableRestWebComponent/src/services/FirstServerResource.java as a web component in Eclipse. Include only org.restlet.jar in the build path library.

Make sure you clean the project and you may check 'build automatically' in the eclipse project tab.

Make sure you have a server running in the background or attached to the eclipse project, like Apache tomcat 6.2 for example.

The console should show the message 'Starting the internal [HTTP/1.1] server on port 8182' instead of showing all those errors you displayed in your question.

Open up a browser and go to the URL http://'localserverIPaddress':8182/test/tutorial and you should see the words hello, world displayed.
