Hi devs,
I got the following exception when I make a GET to a simple REST service
which I tested before and worked fine for me.

Hi all,
I think I found out the solution for this.
Actually this was a fault in my JDK. After re-installing the jdk I am able
to run without an error.
Re: Exception when I call a GET to a simple REST service
Posted by Eranda Sooriyabandara <07...@gmail.com>.
When I run the helloworld-jaxrc sample. It gave me a exception as follows.
(I changed the pom to create the jar and installed it in the tuscany server
and start them and tried to access)

import org.oasisopen.sca.annotation.Remotable;
import javax.ws.rs.*;
@Remotable
public interface HelloWorld {
@GET
@Path("sayHello")
String sayHello(@QueryParam("name") String name);
}
Then I tried out with @Produces and @Consumes
package org.eranda.sca;
import org.oasisopen.sca.annotation.Remotable;
import javax.ws.rs.*;
@Remotable
public interface HelloWorld {
@GET
@Path("sayHello")
@Consumes("text/plain")
@Produces("text/plain")
String sayHello(@QueryParam("name") String name);
}
Now I am not getting the exceptions neither the respond.

Could you please post your resource interface with the proper JAX-RS
annotations which might give us some hints. Without looking at the
code, you might be missing a @Consumes or @Remotable annotation.
