使用JavaScript从jar文件获取返回值

Question

I have learned run a jar file using ActiveXObject Object in javascript. Now, I need to get returned value from jar file. I can't use 'applet' because project requirement.

Here is simple coding...

function RunExe(){  
     w = new ActiveXObject("WScript.Shell");  
     w.run('C://WindowJar.jar');
     return true;
}

How can I get returned value from jar file not using 'applet'.

Thanks your advice.

The only I think this could work is to print the 'returned value' from the jar with the function System.out.println . So you can read this output in the javascript using the code below:

function RunExe(){  
     w = new ActiveXObject("WScript.Shell");  
     var ex =w.Exec('C://WindowJar.jar');
     var ret = "";
     //read the output of the jar
     while (!ex.StdOut.AtEndOfStream) {
         ret += ex.StdOut.ReadLine();
     }
     //alert the output
     alert(ret)
     return true;
}
