Hi All,
Ashwani, thanks for your reply.
Coming to my problem, I have the following two files.
When I call my html file from Internet Explorer, I am getting the following
error: 'document.myform.test.getMonth()' is not an object.
Can any body tell me how to correct this problem?
I have generated a simple applet through Jdeveloper.
Bye

You can use the applet object of the javascritpt to access the
variables.For
applets , you can use the client side javascripting. but for normal java
class function you have to write server side equivalent of the javascript
may be using the liveconnect as you mentioned.
