run dos cammand in java code

[madhuri akhi]

hi
is it possible execute the "dos commands" through "java code"?
give me reply as soon as possible early

[Ulf Dittmer]

That is possible through the Runtime.exec command. Read this article for more details.

As an aside, I think there's a "please" missing in the last sentence of your post.

[Jeroen T Wenting]

in fact you can not execute DOS commands from Java for the very simple reason that Java does not run on DOS.

[Stan James]

In a command window (sometimes called a DOS window ... not exactly true but compatible enough for jazz) enter COMMAND /? and CMD /? In short, you can run programs that are exe files just by putting the names into runtim.exec(). For commands that are provided by COMMAND or CMD you have to start COMMAND or CMD with the command as an argument.

See much better detail and explanations in When Runtime Exec Won't

Ha! Just checked back ... that's the same link Ulf gave. It really will have everything you need.

// any error message?
StreamGobbler errorGobbler = new

// any output?

// kick them off

// any error???
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
} catch (Throwable t)
{

}


}
}

this.is = is;
this.type = type;
}

public void run()
{
