Correct, it's not complete. There is no OpenSRF translator or gateway class
in Java. However, it does implement most of the basics for OpenSRF object
handling and serialization.
I am actually working on android and sending post message to my virtual
machine on which evergreen is installed so i used apache http library..but i
am having some problem..
i am pasting the code written by me
can you please help me out with it..i have browsed over web and this method
for sending json object appeared best to me..
the above json written by me in previous mail is not correct so
for testing purpose i'm working on search books by barcode in which barcade
id is specified by user...
curl -H X-OpenSRF-service: open-ils.search --data 'osrf-msg=[{__p :
{threadTrace : 0, payload : { __c : osrfMethod,__p : { params
:30007004981493,method :
open-ils.search.biblio.find_by_barcode}},type : REQUEST,locale :
en-US},__c : osrfMessage} ]' http://localhost/osrf-http-translator
HttpParams httpParams = new BasicHttpParams();
HttpClient client = new DefaultHttpClient(httpParams);
HttpPost httpost = new
HttpPost(http://+hostname+/osrf-http-translator;);
httpost.setHeader(Accept, application/json);
httpost.setHeader(Content-type, application/json);
httpost.setHeader(X-OpenSRF-service, open-ils.search);
System.out.println(2);
JSONObject data = new JSONObject();
JSONObject _p = new JSONObject();
[snip...]
It's not necessary to build the JSON by hand. You can create an
org.opensrf.Message object, pass in a Java Map or Java Array (or string,
number, boolean, etc. See [1] for options) as the payload object. Then,
simply calling toString() on the Message will generate the JSON for you.

Re: [OPEN-ILS-DEV] Help:opensrf over http using java
Hi,
What you are describing is basically correct. For further reference, see
the login() function at
http://svn.open-ils.org/trac/ILS/browser/trunk/Open-ILS/src/java/org/open_ils/util/Utils.java#L11
For your purposes, you would change the ClientSession.atomicRequest() calls
(which communicate via XMPP) to analogous HTTP requests. As you've probably
discovered, there is no gateway/translator code in Java yet, so the HTTP
handling would be new code.
Hope this helps.

but i'm not able to extract json array from response ..but request

so either the json array in the request is not properly send..or their
