MessageBodyReader exceptions with jersey client

[Larry Touve <lt...@potomacfusion.com>]

(also posted on the jersey list)

I'm trying to use a jersey client application in OSGi, and I'm getting a MessageBodyReader not found exception.  If I run the client application as a standalone POJO, everything works fine, but when I try to run it within an OSGi bundle, I get the exception.  I verified that the bundle is importing jaxb and all other packages that it needs (or at least the ones I think it needs).  I'm using version 1.3 of the jersey client (and version 3.0.1 Final of Glassfish).  I've also tried earlier versions of jersey-client.   Has anyone seen this behavior?

The imported packages within OSGi for my bundle:

My exception:

My client code.  This is the pojo client.  The OSGi bundle code is basically the same, but embedded in some other code within the bundle.

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.config.ClientConfig;
import com.sun.jersey.api.client.config.DefaultClientConfig;
import javax.ws.rs.core.MediaType;

public class JerseyClient
{
    private WebResource resource = null;

    public JerseyClient(String url)
    {
        try
        {
            ClientConfig cc = new DefaultClientConfig();
            cc.getClasses().add(String.class);
            Client client = Client.create(cc);
            resource = client.resource(url);
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }
    }


    public String getResponse()
    {
        ClientResponse response = resource.accept(MediaType.APPLICATION_XML).get(ClientResponse.class);
        String xml = response.getEntity(String.class);     // This is the line that bombs in OSGi
        return xml;
    }

    public static void main(String args[])
    {
        JerseyClient c = new JerseyClient(args[0]);
        String xml = c.getResponse();
        System.out.println("Response: " + xml);
    }
}
