Subject [jira] [Created] (CXF-5240) Jsonp interceptors do not work with GZIPOutInterceptor
Date Wed, 28 Aug 2013 17:20:54 GMT
Vadim Beilin created CXF-5240:
---------------------------------

             Summary: Jsonp interceptors do not work with GZIPOutInterceptor
                 Key: CXF-5240
                 URL: https://issues.apache.org/jira/browse/CXF-5240
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS, Transports
    Affects Versions: 2.5.9
            Reporter: Vadim Beilin


Jsonp support via Jsonp(In,PreStream,PostStream)Interceptor (as described in http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-JSONWithPadding%28JSONP%29)
conflicts with GZIPOutInterceptor.

With a very simple test application request "http://localhost:7543/12?_jsonp=abc" without
Gzip results in the following response 
bq. abc(24);
With Gzip:
bq. abc();24

Apparent reason is that the method org.apache.cxf.jaxrs.provider.jsonp.AbstractJsonpOutInterceptor.writeValue(Message,
String) writes directly to the response output stream. When the method is changed to write
to {{message.getContent(OutputStream.class)}}, responses with and without Gzip interceptor
become the same "abc(24);", as expected.

------------------------

Service code:
{code}
package test.cxf.jsonp;
import javax.ws.rs.*;
@Path("/") @Produces("application/json")
public class Service {
    @GET @Path("{id}") public int find(@PathParam("id") int id) {
        return id * 2;
    }
}
{code}

Configuration (with Gzip)
{code}
<jaxrs:server id="jsonp" address="http://localhost:7543/">
    <jaxrs:serviceBeans>
      <ref bean="serviceBean" />
    </jaxrs:serviceBeans>       
    <jaxrs:inInterceptors>
       <bean class="org.apache.cxf.jaxrs.provider.jsonp.JsonpInInterceptor"/>
       <bean class="org.apache.cxf.transport.common.gzip.GZIPInInterceptor"/>
    </jaxrs:inInterceptors>
    <jaxrs:outInterceptors>
       <bean class="org.apache.cxf.jaxrs.provider.jsonp.JsonpPreStreamInterceptor"/>
       <bean class="org.apache.cxf.jaxrs.provider.jsonp.JsonpPostStreamInterceptor"/>
       <bean class="org.apache.cxf.transport.common.gzip.GZIPOutInterceptor"/>
    </jaxrs:outInterceptors> 
</jaxrs:server>
<bean id="serviceBean" class="test.cxf.jsonp.Service" />
{code}
