Invoking an .exe from a JSP page.

[John Varghese]

Hi everyone,
I'm new to JSP so excuse me if this sounds dumb!!
Is it possible to invoke an external executable (an .exe file) from a JSP page?
My JSP page will capture the configuration details for the program that I've written. Once the parameters have been configured, a start button on the JSP page should invoke the .exe
Is this possible? Are there any flaws/problems that you forsee?
Awaiting your inputs.
Thanks,
VJ.

Well, since a JSP page is simply a servlet then I don't see why not. Try something like this,
<%
Process p = Runtime.getRuntime().exec("ls -a");
// etc ...
%>
Of course, you'd add your own command as the exec parameter.

Thanks for your reply, Sean.
Will there be any performance issues for such an architecture?

It depends. Each time you start an exe , it will be a separate Win NT process .. if the number of users are large, then ... well you can understand ...
