I am using a third-party tool - mdate.jar to use the lt.monarch.swing.JDateField class in my Java Swing application.
When I try to create an object of the class like -
import lt.monarch.swing.JDateField;
.......
private JDateField strtDate = new JDateField();
.......
it compiles down perfectly but I get a run time error as follows:
Exception in thread "AWT-EventQueue-3" java.lang.NoClassDefFoundError: lt/monarch/swing/JDateField

Please help me if I am missing something to achieve this.

you need to include the jar in your classpath

I have included it in the classpath, but even then I am getting the same error.

Am I missing something else? Please suggest

how are you running it?

I compile down all my classes onto the server and access the applets from the asps.

It is a web application and I have also placed the jar in the web-inf folder. Also I have placed the mdate.jar in the jre\lib\ext folder.

Also as you said I have included it in the classpath.
