Calling java app with vba - Java Virtual Machine Launcher error

[Emblem1]

I am attempting to call a java application in Access2007 vba via a button on a form, but getting a "Java Virtual Machine Launcher" error. The code works for most any other application, so I assume I need a different routine to call the java application.

Here is the code:

Private Sub cmdMyButton_Click()
Dim f As String
f = "C:\Program Files\folder1\folder2\javaapp.exe"
Dim RetVal
RetVal = Shell(f, 1)
End Sub

There is actually a .jar file in the same directory as the .exe file, so I think I should just be able to call the .jar file somehow....
