Actually i m having a task where i have to invoke an exe or application which is residing on the client machine.
This particular exe (or application) is to be invoked on click of a button (or hyperlink) present in the JSP (or Servlet) page.
For example say user(the client) is typing a url .Accordingly he is being displayed output of JSP(from Server).This JSP is having a button whoose click event needs to fire an application residing on client machine itself.
I am having trouble doing this , so kindly help me with a sample code or any othere resource.
Thanks n kind Regards ....

Not possible. And a terrible idea. Client-side scripting in web pages is denied access to the client file system for security reasons. Not really the right forum.

Perhaps u r right and i also think ur way but my lead has asked me to figure out a way, that is why i posted it here.
thanks again.
Can u tell me how licensing related thing can be sorted out if one is developing an application (using EJB,JSP and struts framework on Oracle 10g AS).Means we want to create a robust fail proof license for our product(A common licensing related problem is that after expiry a user changees the system date and the application starts working again !!).What should be the ideal approach in the above said technology to achieve this.

What does that have ANYTHING to do with your original question? This is the EJB design forum, anyway...
