如何为最终用户方便地启动Java GUI程序

Question

The user wants to start the Java GUI application from Windows , with some amount of additional JVM parameters.
For instance:

javaw -Djava.util.logging.config.file=logging.properties -jar MyGUI.jar

If I add the above line to the batch file, the user can double-click the batch-file name.
And it's cool. But there is one annoying side effect: the batch file opens the cmd window before starting the GUI .

Is there a simple way to start the java GUI application by double-clicking the batch-file (or some other file which suits the above needs) without opening the cmd window?

Answer 1

I see a number of ways:

• Use a launcher as generated by Launch4J (thanks to CodeBrickie for the tip) or Install4J/Exe4J . Launch4J allows you to tweak the parameters by creating an .l4j.ini file with the same name as the exe. In case of Exe4J, extra parameters can be specified in a .vmoptions file which you drop next to the generated exe.
• Create a Shortcut to javaw.exe, give it the icon you want, set the "Start in" field to the directory of the application and specify your parameters to javaw in the Target field.
• Make a VB script which launches javaw. If the VBS runtime is set to use wscript , no console window will pop up.
• If you use Java Web Start, you might want to let the user tweak the JNLP file as specified in Java Webstart with parameters .

Try

start javaw -Djava.util.logging.config.file=logging.properties -jar MyGUI.jar

You can also use scripting :

VBS:

Const HIDDEN_WINDOW = 12 

strComputer = "." 
Set objWMIService = GetObject("winmgmts:" _ 
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") 
Set objStartup = objWMIService.Get("Win32_ProcessStartup") 

Set objConfig = objStartup.SpawnInstance_ 
objConfig.ShowWindow = HIDDEN_WINDOW 
Set objProcess = GetObject("winmgmts:root\cimv2:Win32_Process") 
errReturn = objProcess.Create("Notepad.exe", null, objConfig, intProcessID)

JScript:

var WindowStyle_Hidden = 0
var objShell = WScript.CreateObject("WScript.Shell")
var result = objShell.Run("cmd.exe /c abc.bat", WindowStyle_Hidden)

Finally, there are general-purpose utilities you can use to hide windows, such as CMDOW and Hidden Start ($20) . I have not used either myself, since start does the same thing.

Answer 3

The user wants to start the Java GUI application ..

The best user experience for the end user will be offered by launching the app. using Java Web Start . JWS can install desktop shortcuts and menu items to launch the app.

..from Windows..

JWS also works on OS X & *nix.

Lauch4j可以将你的jar包装在exe文件中。
