I have written an applet program. It has some references to classes from java tools.jar in it (eg:- import com.sun.jdi.connect.IllegalConnectorArgumentsException)

When I run this applet through appletviewer utility it works fine. But when I embed this applet in HTML file and try to run it through web browser, I am getting exception about some classes not found at runtime:-

However the IllegalConnectorArgumentsException class is part of java runtime located inside tools.jar.

How I can get run it inside browser as well?

many thanks in advance.

Do I need to create self signed jar of all my files supporting applet and need to add entry for tools.jar inside META_INF/MANIFEST.MF ?
I agree. Here's the link: http://aspose.com/file-tools
