Browse a file and run an .exe file

[KKG]

Hi,Could some one help me in resolving this.I would appreciate for any help.
In a jsp page I have a browse file option and submit button. When I browse the file and click submit, a .exe file should run based on the browsed file.(Please note that the browsed file is not the .exe file).This I want to do from a web page.
The same can be done from the command prompt in the following way:
cmd: C:\tools\server\grd.exe -c C:\files\test.lic
where -c C:\files\test.lic is the command to list the files in that location.
C:\tools\server\grd.exe is the command to run the .exe file.
My requirement is I have to do this in a webpage. As it works in the command prompt the same way it should work in the webpage but I have to browse the file and then run the .exe file.

Don't do it in a JSP, do it in a servlet. And since a servlet is basically just a Java class, you are free to use the Runtime or Process class in it to invoke a system command.

Yup, am doing this in servlet. Am using jsp to create the view with buttons.

Excellent. But did you also manage to implement your requirement now?

Not yet. I mean though i browse different files and click submit button it is showing me the result of the same file that I selected first. below is the code snippet.

java code:

protected void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

try{

res.setContentType("text/html;charset=UTF-8");
PrintWriter out = res.getWriter();

Runtime rt = Runtime.getRuntime();

Process p = rt.exec("C:\\tools\\server\\grd.exe " );


out.println("ServerStarted");

}catch (Throwable t)
{
t.printStackTrace();
}


finally {

} }
}

jsp code:
<form action="clpstart" METHOD="GET" enctype="multipart/form-data">
<input type="file" name=browsefile size="150" />
<input type="submit" name="start" value="StartServer" />
</form>
</td>

I did not even hardcoded the file that I want to browse but still it takes the same file that I mentioned in my question above.

But that code just runs the exe.
There's no mention there of the file the client has uploaded.
