How to use Wscript Exec to run a Java file

Question

As the description of Wscript:String value indicating the command line used to run the script: The command line should appear exactly as it would if you typed it at the command prompt.

I can run my java file using the command "java test http://www.bbc.co.uk/news/world-us-canada-12116778" but it is not working when I wrote the JavaScript below. Can someone can tell me why? Thank you or can tell me there is some other method to call my Java file when I open a html file?

<script type="text/javascript">
funciton {}
var WshShell = new ActiveXObject("WScript.Shell");
var oExec= WshShell.Exec(""java test http://www.bbc.co.uk/news/world-us-canada-12116778"");
while (oExec.Status == 0)
{
     WScript.Sleep(100);
}
</script>

Well, running such scripts properly require to change the client's security settings. If want to run Java code maybe you should write an applet or look at Java Web Start technology? — Lukasz

Agree with Lukas, but if you are commited...Do you have an error message ? Also, your call implies you are calling a class called "test". That means you need a file called "test.class" somewhere in the classpath of the shell that is being invoked. And, "java.exe" also needs to be in the PATH since it is not fully qualified. I feel like eventually you will need to do something like "c:\java\bin\java.exe -jar test.jar ......." because your command line (shell) probably has some environment setup that Wscript called from the browser does not have. — Nicholas

Take a look at the WSHSell object's run method. The following code works for me:

var shell = new ActiveXObject("WScript.Shell");
shell.run("cmd /c java -jar MyApplication.jar");
// should work without JARs as well, take care for the working path

The run method has an option to wait for the java program to return.

Hope this helps.
