Java: run as administrator

Question

Is there a way in Java to ask the system to get control over administrator functionality. Of course without doing: Right click on the exe -> run as admin.
What I want is that there comes a frame from UAC like in Windows Vista or Windows 7.

Or have I to do some settings while making an exe from the jar?

Answer 1

You have to create a manifest file that specifies that your application needs administrator permissions. You can include the manifest in your exe or keep it as a separate file (yourapp.exe.manifest)

Answer 2

The easiest way would be to use a wrapper to launch your JVM, then elevate the wrapper. I use a simple NSIS installer script with the UAC plugin to do this:

; Java Launcher ;--------------  ; You want to change the below lines    Name "my program"    Caption "my program Launcher"     Icon "iconfile.ico"     OutFile "java launcher.exe"  ; param below can be user, admin     RequestExecutionLevel admin  !include UAC.nsh  SilentInstall silent AutoCloseWindow true ShowInstDetails show  Section ""       ; command to execute       StrCpy $0 'javaw -jar myjarfile'         SetOutPath $EXEDIR       Exec $0     SectionEnd
