Running Jar File via VBScript

Question

I have a jar file that I would like to run using VBScript. But I don't want to leave the command prompt open while the application is running.

Currently, I can achieve this by putting the java command in a BAT file as follows:

java -Xms256M -Xmx1024M -jar myApp.jar

I then have a VBScript that would call the BAT file as follows:

Set WshShell = CreateObject("WScript.Shell") 
WshShell.Run chr(34) & "myApp.bat" & Chr(34), 0
Set WshShell = Nothing

But I think that using a VBScript to call a BAT file to invoke the java command is unnecessary. To optimize, I wanted the VBScript to invoke the java command directly so that I can disregard the BAT file.

I tried replacing the VBScript into something like the following:

Set WshShell = CreateObject("WScript.Shell")
WshShell.Run chr(34) & "java -Xms256M -Xmx1024M -jar myApp.jar" & Chr(34), 0
Set WshShell = Nothing

But the following error occurs:

Error: The system cannot find the file specified.
Code: 80070002

Any ideas?

Use `WshShell.Run "cmd /c java -Xms256M -Xmx1024M -jar myApp.jar"`. — user692942, Oct 22 '20 at 09:02

@Lankymart Yup, saw these posts when I was searching. The first one does not work on me. The second 1 somewhat works but the command prompt is still visible. — RanRan, Oct 22 '20 at 09:21
You should remove those `chr(34)` before and after your command — Mark Rotteveel, Oct 22 '20 at 09:43
@MarkRotteveel Removing the chr(34) works. But the command prompt shows while the app is running. I wanted the command prompt not to be displayed while the app is running. — RanRan, Oct 22 '20 at 10:09
@MarkRotteveel Literally didn't know about javaw. Thanks man! This now works! — RanRan, Oct 22 '20 at 10:29

Change "java" to absolute path such as "C:\Program Files\jdkXXX\bin\java.exe"

Since this will be used by several users, is there anyway that the script to search the actual location of the java.exe? – RanRan Oct 22 '20 at 09:22
