Violet UML Editor

here is a solution, don't know it leaves traces or not and I suck whit bat files but it works. Can a pro look at this?
1)make the common portable apps hierachie, look at how apps are designed and make an empty app
2)create a new bat file named run.bat with as content: (CAN A PRO LOOK AT THIS?)
IF NOT EXIST ..\commonfiles\java GOTO systemcheck
..\commonfiles\java\bin\java.exe -jar app\com.horstmann.violet-0.21.1.jar
GOTO end
:systemcheck
IF NOT EXIST java.exe GOTO end
java.exe -jar app\com.horstmann.violet-0.21.1.jar
:end
3) download this:http://download.cnet.com/Bat-To-Exe-Converter/3000-2069_4-10555897.html and convert that bath to an invisible exe, its an option. and place the created run.exe in the root of your application mapp
4) place the jar in the app map and in the app/appinfo map there should be an ini file you created if you maked the common hierachie, type in it:
