Help! I can't use smack_4_1_1 to connect

I am a new man to use this ,so I download the openfire_3_10_0.exe,and run well,

I also use spark_2_7_0.exe to communicate with my colleague,


then ,I try to use java to connect with smack_4_1_1 ,but failed,I copy the API’s guide,but I doesn’t work.

Someone can help me to find that What’s wrong with my code??? thank you very much!!!

then I add some jars from openfire/lib

I have tried different ways to connect,now ,the exception is:

any help would be appreciated!!!

sorry ,I just add some jars not from openfire/lib,

I copy from asmack-master\lib


Add the following jar to your libs folder.

  • jxmpp-core-0.4.1
  • jxmpp-util-cache-0.4.1
  • minidns-0.1.1
  • smack-android-4.1.0.jar
  • smack-android-extensions-4.1.0
  • smack-core-4.1.0
  • smack-extensions-4.1.0
  • smack-im-4.1.0
  • smack-tcp-4.1.0
  • smack-sasl-provided-4.1.0.jar
    I was having the same problem but after adding the above mentionend JARs, I was able to set up a connection with the server.

thank you so much!

I’m so excited ,because I can send simle message in Java.

I changed 2 jars :

  • jxmpp-core-0.4.1
  • jxmpp-util-cache-0.4.1

At first ,I used these old jars from asmack-master,maybe the main reason is here.

  • jxmpp-core-0.1.0
  • jxmpp-util-cache-0.1.0

I also add other jars that you didn’t mention ,maybe because of the smack_4_1_1.

even though the new exception is coming,I can send message to others…

thanks again!!!
