Hi all,
I have some issues with the GZipContentEncodingFIlter and Viewables.
Within my Resource I return a Viewable like:
return Response.ok(new Viewable("/foo", model)).build();
Unfortunately the gzip Filter commits the response before the jsp is rendered.
Servlet.service() for servlet [default] in context with path [/foo] threw exception [com.sun.jersey.api.container.ContainerException: java.lang.IllegalStateException: Cannot forward after response has been committed] with root cause

My pesonal workaround is to patch the Filter:
(from line 104:)
if (!(response.getEntity() instanceof Viewable)) {
response.getHttpHeaders().add(HttpHeaders.CONTENT_ENCODING, "gzip");
response.setContainerResponseWriter(
new Adapter(response.getContainerResponseWriter()));
}
Viewables will not be gziped, but thats fine for me. Let me know if I'm missing something or if there is a better solution.
Regards,
Martin
