Running a RESTlet Tutorial, I get java.lang.NoClassDefFoundError

Question

I am trying to run the first server tutorial on RESTlet docs , but I am getting errors, although I have added banks to my class path. I added org.restlet.jar and org.restlet.ext. *

Code for server:

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 get are the following:

What am I missing?

Answer 1

This was an Eclipse problem, I had to remove all the banks and add only org.restlet.jar and also clean the project. After I did this, everything worked as expected.

Answer 2

Thanks. I also had a problem with the NetBeans IDE. I deleted the org.restlet.ext.httpclient-2.1m1.jar file from the lib project and no errors since then.

Answer 3

Just update this, from the last folder restlet-jee-2.0.10/lib copy org.restlet.ext.servlet.jar and org.restlet.jar . This 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 can check the 'build automatically' in the eclipse project tab.

Make sure you have a server running in the background or connected to an eclipse project, such as Apache tomcat 6.2.

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

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