Paul,
I created another method (note the media type!!)
@GET @Produces("text/plainx")
public Response getResource() {
StreamingOutput o = new StreamingOutput() {
public void write(OutputStream outputStream) {
PrintWriter out = new PrintWriter(outputStream);
out.println("AAAAA");
out.close();
} };
return Response.ok(o).build();
}
This works. If I use text/plain the resource class name is returned
as output.
Hmmm - that leaves me clueless I guess :-)
Any idea?
Jan
P.S. here is the complete class:
package foo.resources;
import java.io.OutputStream;
import java.io.PrintWriter;
import javax.ws.rs.*;
import javax.ws.rs.core.*;
@Path("/worksets/{worksetId}/{timestamp}/readwrite")
public class WorkSetRetrieve {
@GET @Produces("text/plainx")
public Response getResource() {
StreamingOutput o = new StreamingOutput() {
public void write(OutputStream outputStream) {
PrintWriter out = new PrintWriter(outputStream);
out.println("AAAAA");
out.close();
} };
return Response.ok(o).build();
}
}
