No thread local value in scope for proxy of class $Proxy55

Hello Michael,

if its within same webapp (I presume it is), you can use
ContainerRequestFilter - short sample:

// redirects *helloworld to *helloworld/something
public class MyFilter implements ContainerRequestFilter {
@Override
public ContainerRequest filter(ContainerRequest request) {

try {

if(request.getAbsolutePath().toString().endsWith("helloworld")) {
request.setUris(request.getBaseUri(),
request.getRequestUriBuilder().path("something").build());
}

return request;
} catch (Exception e) {
// add proper handling
}

return null;
}
}

I have to admit I don't really know why your case don't work, but it
might be meant for lower level use / redirecting to another
servlet/filter maybe.. not sure. Anyway ContainerRequestFilter should
work for you (but its Jersey specific). See
http://jersey.java.net/nonav/apidocs/1.11/jersey/com/sun/jersey/spi/container/ContainerRequestFilter.html.

Regards,
Pavel

Hi all,
I am having an issue forwardig a request from one resource to another.
I get the following exception: java.lang.IllegalStateException: No
thread local value in scope for proxy of class $Proxy55
The sample code below reproduces this issue.
@Path("/forwarder")
public class ForwardingResource {
@GET
@Produces("text/plain")
@Context HttpServletResponse response) throws ServletException,
IOException {
request.getRequestDispatcher("target").forward(request, response);
return ""; // Nothing
}
}
@Path("/target")
public class TargetResource {
@GET
@Produces("text/plain")
public String getContent() {
return "I am the target";
}
}
When I call
Client c = Client.create();
WebResource r = c.resource("http://localhost:8080/jersey.repo1");
String result = r.path("forwarder").get(String.class);

I am running jersey within tomcat 6.

Any suggestions or workarounds would be much appreciated!
