Please,

Can I execute a .bat file from Java applet?

I am trying execute a .bat file by using exec(String) method.

My code is:

param.bat
---------
c:\dos\tree.com

myFile.java
------------
        Process proceso;
        try
        {
            System.out.println("Runtime:"+Runtime.getRuntime());
                   
proceso=Runtime.getRuntime().exec("c:\\sistel\\ejemjava\\pt\\param.bat");

            System.out.println("proceso:"+proceso);
        }
        catch(IOException e)
        {
            System.out.println("bad shell");
        }

        System.out.println("The end");
    }


It do not execute the command system 'tree', but it print "The end".

It is right if I do not use a bat file, like this:

proceso=Runtime.getRuntime().exec("c:\\dos\\tree.com");

Thank you,

Arancha

Try
Runtime.getRuntime.exec("command.com /c c:\\sistel\\ejemjava\pt\param.bat");

On NT, command.com would be cmd.exe, instead.  

I would like to know how to get at system environment variables from java.
