problems loading jetty - "Illegal context spec:null"

Hi,
when I try to start a CamelContext with a simple route
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;


public class Main {

	public static void main(String[] args) throws Exception {
		DefaultCamelContext camelContext;

		camelContext = new DefaultCamelContext();
		camelContext.addRoutes(new RouteBuilder() {
			public void configure() {
				from("jetty:http://localhost:9080?matchOnUriPrefix=true")
					.to("mock:one");
			}
		});	
		camelContext.start();
		Thread.sleep(10000);				
	}
}

using jetty-6.1.9 i get the following Output and Exception

20.03.2010 14:07:25 org.apache.camel.impl.DefaultCamelContext doStart

The Class is started in Eclipse. 
The Libraries come from Camel 2.2.0 and ActiveMQ 5.3.0 releases. I am not
using maven but have downloaded the libs explicitly.

since all posts i found concerning this Exception gave me no clue for
solving my problem, i am posting here.

thanks i advance
Henning

Re: problems loading jetty - "Illegal context spec:null" - SOLVED!!!

Posted by hdev <he...@berlin.de>.
YESYESYES!
that did it

after replacing jetty-6.1.9 libs with the 6.1.22 libs everything went fine.

Thank you very very much for your short and precise analysis, this helped me
a lot!

Hi

Camel 2.2.0 is using Jetty 6.1.22, so maybe the old 6.1.9 has an issue.
Here is the Maven generated dependency:list for camel-jetty in Camel 2.2.0:

Re: problems loading jetty - "Illegal context spec:null"

Posted by hdev <he...@berlin.de>.
Hi Willem,
thank you for your reply.

Unfortunately the problem must be somewhere else

I tried some combinations always getting the same Exception:

  jetty:http://localhost:9080/?matchOnUriPrefix=true
  jetty:http://localhost:9080/MyApp/?matchOnUriPrefix=true
  jetty:http://localhost:9080/
  jetty:http://localhost:9080/MyApp/
  jetty:http://localhost:9080/MyApp/FooBar

This is the first excercising with camel, so the Error might be somthing
really really stupid, since no one else seams to have this problem. 
I successfully created consuming and producing endpoints for jms, active-mq,
mina tcp, file and so on, but the simplest jetty:http refuses to work.

So i am a bit clueless at the moment...

Maybe there is something wrong with the loaded jar versions.
This is the list of jars that a currently referenced in the eclipse project

        apache-activemq-5.3.0/lib/web/slf4j-jcl-1.5.0.jar

These containbs also the jars for the other referenced endpoints i tried
also.
but i think the jars should all be ok or at least up to date. or is there
something missing.

Perhaps i should reduce the scenario to find the problem.
What would be the minimal environment of jars to start a camel jetty:http
endpoint from JavaDSL? 

thanks in advance for replies,
Henning

Re: problems loading jetty - "Illegal context spec:null"

Posted by Willem Jiang <wi...@gmail.com>.
Hi,

You got this kind of exception, because you didn't specify the context 
path. Please change the RouteBuilder configure method like this

from("jetty:http://localhost:9080/?matchOnUriPrefix=true").to("mock:one");

Willem
