I'm new in camel world and I have problems making a connection with the jcr component. look at my test code:

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.jcr.JcrConstants;
import org.apache.camel.test.junit4.CamelTestSupport;
import org.junit.Test;


public class ObjectToJCRRouteTest extends CamelTestSupport {

    @Override
    protected RouteBuilder createRouteBuilder() throws Exception {
        return new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("direct:a")
                        .setProperty(JcrConstants.JCR_NODE_NAME,
                                constant("node"))
                        .setProperty("my.contents.property", body())
                        .to("jcr://admin:admin@localhost:8080/home/test");
            }
        };
    }

    @Test
    public void putJCRNode() throws Exception {
        template.sendBodyAndHeader("direct:a", null, null, null);
        Thread.sleep(1000);
    }
}

I tried wiht jcr://admin:admin@localhost/home/test", "jcr://admin:admin@localhost:8080/home/test" , "jcr://admin:admin@localhost:8080/repository/home/test"

I tested jackrabbit with a repository explorer (http://www.subshell.com/en/toromiro/index.html) using rmi and the connection was succesfull

thanks in advance by any help!!!

my jackrabit server is:

The host part of a Camel jcr: url should not refer to an actual network host, but to a javax.jcr.Repository object instance that is defined in the Camel registry. Most of the times, this means it will be defined as a bean in a Spring or Blueprint XML file.

To do the same thing in a unit test, you can override the createRegistry method to add beans to the Camel registry. In the code example below, a JackRabbit URLRemoteRegistry is added to the Camel registry with name MyJCR.

The route itself is using the URL jcr://admin:admin@MyJCR/default/home/test. Note that /default part of the URL was added to point to the JCR repository workspace to add nodes to.

public class ObjectToJCRRouteTest extends CamelTestSupport {

  @Override
  protected RouteBuilder createRouteBuilder() throws Exception {
    return new RouteBuilder() {
      @Override
      public void configure() throws Exception {
        from("direct:a")
              .setProperty(JcrConstants.JCR_NODE_NAME,
                           constant("node"))
              .setProperty("my.contents.property", body())
              .to("jcr://admin:admin@MyJCR/default/home/test");
      }
    };
  }

  @Override
  protected JndiRegistry createRegistry() throws Exception {
    JndiRegistry registry = super.createRegistry();
    registry.bind("MyJCR", new URLRemoteRepository("http://localhost:8080/rmi"));
    return registry;
  }

  @Test
  public void putJCRNode() throws Exception {
    template.sendBody("direct:a", "Some contents");
    Thread.sleep(1000);
  }
}
