Hey folks, I am trying to connect to XMPP server on my localhost. but every time i try to do this i keep getting multiple error like SSL etc. Is there any complete example where i ca connect to XMPP server and send messages from user1 to user2. I have tried too many methods but none of them worked. Can someone please help me.
The Openfire documentation contains a number of minimal examples using various libraries (mostly third-party) that illustrate how they can be used to interact with Openfire. We obviously have one for Smack, too: Smack: A Minimal Working Example (in Java)
Hey Guus, Thank you for replying to my topic. I have tried the exact same code from above but i keep getting this two errors.
Also can I use xmpp to send and receive push notifications to android and ios devices?

org.jivesoftware.smack.SmackException$SecurityRequiredByServerException: SSL/TLS required by server but disabled in client
The reason for the failure is expressed in this error message:
SSL/TLS required by server but disabled in client
The demo code disables encryption, because setting that up typically involves the client trusting certificates issued by the server (which can get complex).
Your server apparently is configured to require encryption. That is why the demo code is not working.
As for push notifications: yes, those are supported in XMPP, but that’s an entirely different (and complex) topic. The specification is documented here: XEP-0357: Push Notifications
