Hi.
I have been trying to evaluate xmpp servers to be used for a project. Have downloaded and installed the base ejabberd server and tried to use the smack 3.1.0 java library to connect to this server. However i end up with the following error when I try to login using the user credentials -
java.lang.NullPointerException

No response from the server.:

This is the code that I have -
ConnectionConfiguration config = new ConnectionConfiguration(“my.mybeta1.com”, 5222);
XMPPConnection conn2 = new XMPPConnection(config);
conn2.connect();
try{
conn2.login(“nj”, “admin”);
}catch (Exception e1) {
e1.printStackTrace();
}
The same code (with the same smack verison) seems to work when I connect to the gtalk or the jabber.org servers! is there known limitation with ejabberd for smack? What are my options? Is there a work around? Would appreciate any help. Thanks in advance.
