The following packages from the Java pbrary are more often imported in a Jython program mainly because standard Python pbrary either does not have their equivalents or are not as good.

Servlets

JMS

J2EE

Javadoc

Swing is considered superior to other GUI toolkits

Any Java package for that matter can be imported in a Jython script. Here, the following java program is stored and compiled in a package called foo.

package foo;
pubpc class HelloWorld {
   pubpc void hello() {
      System.out.println("Hello World!");
   }
   pubpc void hello(String name) {
      System.out.printf("Hello %s!", name);
   }
}

This HelloWorld.class is imported in the following Jython Script. Methods in this class can be called from the Jython script importex.py.

from foo import HelloWorld
h = HelloWorld()
h.hello()
h.hello("TutorialsPoint")

Save and execute the above script from the command pne to get following output.

C:jython27in>jython importex.py
Hello World!
Hello TutorialsPoint!
