DOS command window

[Younes Essouabni]

I have a small application ,I launch this application from a .bat,and I want to know if it's possible to launch this application without having a DOS window open! Is it possible to hide or close the dos window? Or any other way to launch the application?
Any help is welcome!
thx

Investigate using the javaw command (instead of java) in your batch file.

Thx I am investigating!

Try using "javaw" instead of "java -jar". javaw is what is called when you double click on a jar file. The only difference that I have found(I am sure there are others) is that it won't open a dos window to run. Which has advantages and disadvantages.
Adv: don't have a pesky dos window hanging around
DisAdv: don't have any place to read System.out.println that may generated from errors in running the jar.
HTH,

I tried javaw instead of java. It works but the dos window is still opening, however now I may shut it down. I am still looking for a solution where the dos window does not open, or some code that will close the window automatically!
I think that it's not really professional to ask a user to close a window each time he start an application! Are your professional application working with that window?
Let me know please!

javaw.exe. used to not have a DOS window. However a zillion problems arose from not having a place to dump error messages, so now it also has one.
Yes - our production systems have DOS windows open with them. The users just minimize it if they don't like it.

Of course the easiest way is to put it in a jar file. Then just add a shortcut to the .jar file and run that directly. No pesky javaw or .bat files to worry about.

You need to call the bat file from a windows sub shell. For example:
c:> cmd /c test.bat
Carry out the command and terminate.
Use the /? flag to check the help.
c:> cmd /?

Thx for all your reply, I am thinking of doing a .jar, although I really don't know how to do it.
It can't be hard, so I'll find it!
Again thank you all!

If you create a batch file (.bat) to load your application using javaw, then you can set the properties of the command window (click on the A button) so that it loads in a minimized window and then closes on exit.
Hope this helps

jar cvf "java class file names": It is similar to
tar archive command in unix

Try:
SmartJ Java launcher, version 0.60, 4 May 2001

normally what I do is just create a shortcut to "javaw package.ClassName" and then execute that. The window does not appear and you can assign any icon you wish.
