Smack ejabberd connection error

I am looking for a simple exmple to connect ejabbered using smack java client. Here is something i tried

    XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
    builder.setUsernameAndPassword("admin1@ejab", "123456");
    builder.setServiceName("ejab");
    builder.setHost("localhost");     
    builder.setPort(5280);

    XMPPTCPConnectionConfiguration build = builder.build();

       AbstractXMPPConnection conn1 = new XMPPTCPConnection(build);
       conn1.connect();

I am getting 

org.jivesoftware.smack.SmackException$NoResponseException: No response received within reply timeout. Timeout was 5000ms (~5s). Used filter: No filter used or filter was 'null'

i am able to browse http://localhost:5280/admin . What is servicename & host. Can anyone give a simple example ?

According to smack API, setServiceName parameter should be the domain of the XMPP service, so, in your case, it should be "ejab" (I suppose account "admin1@ejab" is correctly set in ejabberd). You can check with the section Hostname at ejabberd.cfg file.

e.g. from default ejabberd.cfg file

%% Hostname

{hosts, ["localhost"]}.

==> localhost is set as the service name

The setHost function parameter should be the server IP address or DNS resolvable server name. From your description that you access the ejabberd admin page using localhost, use the computer IP address that installed with ejabberd will be simpler.

Also, setPort should be the port that ejabberd listening at and its default is 5222 instead of 5280 (5280 is for administration through web). You can check with the listening ports from the ejabberd.cfg file to confirm.

e.g. from default ejabberd.cfg file

{listen,

[

{5222, ejabberd_c2s, [ .........

Below are the steps for adding a self signed certificate such that smack can work with. (Note : I use ubuntu server for following commands with openssl installed.)

  1. create a certificate

    openssl req -new -x509 -newkey rsa:1024 -days 3650 -keyout privkey.pem -out server.pem

    openssl rsa -in privkey.pem -out privkey.pem

    cat privkey.pem >> server.pem

    openssl rsa -in server.pem -out newcert.pem

    openssl x509 -in server.pem >>newcert.pem

    sudo cp newcert.pem /etc/ejabberd/

  2. modify ejabberd.cfg to use the certificate

    {5222, ejabberd_c2s, [

                          {access, c2s},

                          {shaper, c2s_shaper},

                          {max_stanza_size, 65536},

                          starttls, {certfile, "/etc/ejabberd/newcert.pem"}

                         ]},

    {s2s_use_starttls, true}.

    {s2s_certfile, "/etc/ejabberd/newcert.pem"}.

  3. restart the service

    sudo service ejabberd restart
