The classes are executed on the client, so the fact that WebSphere does not have these classes doesn't matter. They are part of the Java Plugin, so they are in the browser where the applet runs. As long as the Sun Java Plugin is installed, this should with all current browsers.
In my JDK installation they are in a file called "plugin.jar" in the directory jre/lib.
Thanks ULF ,after importing plugin.jar into WSAD ,i m able to import netscape.
I have doubt. Now I am embeding applet in a jsp page,which contains java script( and i am calling this jsp through action class of struts frame work ). Let there is a button named Save on the applet.So when I press save button an action event takes place and in that method i want to call java script of the web page through Live connect (JSObject ) concept. So in that java script can I submit the form and call action class (struts frame work ).
