[rabbitmq-discuss] Broker data

Thu Apr 2 20:01:27 BST 2009

I have found out the various commands which I need to invoke to get the data
exposed via rabbitmqctl. Have been able to get the values via the JInterface
for some of them. But for queue, exchange related information I am not able
to get things via JInterface. The erlang command which I invoke to get the
list of exchanges :
rpc:call(rabbit at server,rabbit_exchange,info_all,[<<"/">>],3000)]

The above command represented in JInterface code :

        OtpSelf self = new OtpSelf("client", "rathitest");
        OtpPeer other  = new OtpPeer("rabbit at server");
        OtpConnection connection = self.connect(other);
        OtpErlangObject [] obj = {new OtpErlangAtom("<<\"/\">>")}
        OtpErlangList  arg = new OtpErlangList(obj);
        connection.sendRPC("rabbit_exchange","info_all",arg);

When I invoke the above given code it gives :

test :
receiveRPC{badrpc,{'EXIT',{function_clause,[{rabbit_misc,r,['<<\"/\">>',exchange]},{rabbit_exchange,list,1},{rabbit_exchange,map,2},{rpc,'-handle_call/3-fun-0-',5}]}}}

Can anybody please suggest what is going wrong here.

thanks & regards,
rathi
