running a vbs file from java

Question

I have a VBS file test.vbs in C:/work/selenium/chrome/ and I want to run it from my Java program, so I tried this but with no luck:

public void test() throws InterruptedException {
   Runtime rt = Runtime.getRuntime();
   try {
      Runtime.getRuntime().exec( "C:/work/selenium/chrome/test.vbs" );
   }
   catch( IOException e ) {
      e.printStackTrace();
   }
}

If I try to run some exe file with this method it runs well, but when I try to run a VBS file it says "not a valid win32 application".

Any idea how to run a VBS file from Java?

Solution 1

A vbs-Script isn't natively executable like a bat, cmd or exe-Program. You have to start the interpreter (vbs.exe?) and hand your script over as a parameter:

String script = "C:\\work\\selenium\\chrome\\test.vbs";
// search for real path:
String executable = "C:\\windows\\...\\vbs.exe"; 
String cmdArr [] = {executable, script};
Runtime.getRuntime ().exec (cmdArr);

Solution 2

public static void main(String[] args) {
   try {
      Runtime.getRuntime().exec( "wscript D:/Send_Mail_updated.vbs" );
   }
   catch( IOException e ) {
      System.out.println(e);
      System.exit(0);
   }
}

This is working fine where Send_Mail_updated.vbs is name of my VBS file

Solution 3

try {
        Runtime.getRuntime().exec(new String[] {
        "wscript.exe", "C:\\path\\example.vbs"
        });        
    } catch (Exception ex) {
        ex.printStackTrace();
    }

You can use the code above to run vbs file.

Solution 4

Runtime.getRuntime().exec( "cscript E:/Send_Mail_updated.vbs" )

The code which reads the stdout and stderr is likely to deadlock. To code this properly, you must use separate threads to read the output streams of the process
