Java.io.EOFException: No more data available - expected end tag </ stream: stream> to close start tag <stream: stream>

I am working on a chat app using xmpp. As per our requirement, we have three Apache Tomcat 7 servers, ejabbered 2.1.11 and mysql 5.5,

to run xmppbot on tomcat  used below library
    -Smack-core-4.0.3.jar
    -smack-tcp-4.0.3.jar
    -xlightweb2.5.jar
    -xpp3-1.1.3.3.jar
    -xSocket-2.4.6.jar

Using the above library, I can connect to ejabberd and login with my login id and password, but after some time logging into the connection, it closes automatically and I get below the stack trace

  • What is the reason for the above error?

Then the connection dropped unexpectedly. For example, because the server closed it in an unclean way.



  1. How can I solve the above error?

There may be many reasons for this. You must handle the exception and reconnect.

You need to set an interval (ping) to overcome the idle connection timeouts. Timeouts do not have to be in applications, they can be in routers / switches along the way. In example 600 is 10 minutes.



PingManager.getInstanceFor (connect) .setPingInterval (600);
