could u please help me

In your project you need to include classpath to this library from your IDE, for example in NetBeans you can do as described here

actually i m using editplus editor, i dont use NetBeans

please help me

Then read the help file for that editor on how to include libraries on the classpath.

smack package? What's it do? Spank you?

Use Apache Ant as a build tool to compile your application with dependencies or just use the command line invocation of `javac' and `java' which supports classpath options.
