vba to open java window

I'm looking for a simple method in vba to open a java window (file) on the lines of

• 
  Sub openstuff()
  
  Shell("java.exe -jar" & "C:\myaddressFile\mytargetInfo.jar")
  
  End Sub

That runs ok but nothing happens!
Anyone help?

 

You have space missing between "-jar" and the file name

 

Many thanks LeeD, I'm much obliged to you
