I am not sure, but i think you dont need to(should not) set fromJid, as
message will be sent from your application JID.
I am running following code and its working .
JID jid = new JID(responseJid);
Message msg = new MessageBuilder()
.withRecipientJids(jid)
.withBody(msgBody)
.build();
boolean messageSent = false;
XMPPService xmpp = XMPPServiceFactory.getXMPPService();
if (xmpp.getPresence(jid).isAvailable()) {
SendResponse status = xmpp.sendMessage(msg);
messageSent = (status.getStatusMap().get(jid) ==
SendResponse.Status.SUCCESS);
}
