solr - How to get the raw binary content in Grails controller -

after many days of search , many unsuccessful tries, hope community knows way achieve task:

i want use grails kind of proxy solr backend. this, want ensure authorized requests handled solr. grails checks provided collection , requested action , validated request predefined user based rules. therefore, extended grails url mapping to

"/documents/$collection/$query" {     controller = "documents"     action = action = [get: "proxy_get", post: "proxy_post"] } 

the proxy_get method works fine when client using solrj. have to forward url request solr , reply solr response.

however, in proxy_post method, need raw body data of request forward solr. solrj using javabin , not able far raw binary request. promising approach this:

defaulthttpclient httpclient = new defaulthttpclient(); httppost httppost = new httppost(solrurl); inputstream requeststream = request.getinputstream(); contenttype contenttype = contenttype.create(request.getcontenttype()); httppost.setentity(new bytearrayentity(ioutils.tobytearray(requeststream), contenttype)); httppost.setheader("content-type", request.getcontenttype()) httpresponse solrresponse = httpclient.execute(httppost); 

however, transferred content empty in case of javabin (e.g. when add document using solrj).

so question is, whether there possibility raw binary post content can forward request solr.
