JFrame help

Posted: Aug 5, 2002 6:12 PM

How do I create an application in java that doesn't need dos/the method main() to run it. Like when I want to run my application with a gui I have to create a new instance of it in my main method. And then when I run the application a dos window comes up first and then the frame with my gui. can anyone help? I would just like to create an application that doesn't have a dos window appear first before the gui.

Hi,

just pack your classes to an executeable jar file.
first you have to create a manifest file that contains this line : Main-Class: MainClass
(type enter after this line)
save this file as manifest or something else.
than use the jar tool to create the jar file like :
jar cmf manifest jarname.jar *.class

regards, trung

ok, when you create an application with a Frame, and you run it through an IDE like JCreator. Before you see the Frame appear, a dos window appears, and a few seconds later your JFrame appears. I want to know how to make that dos window not appear, and just have the frame appear. Do you understand?

Hi jake,

You can start the whole thing either with the command
java or javaw.

Funnily enough, the command you are looking for is javaw (meaning NO console window).

RTFM ;-)

Additionally, you can probably customize your development environment to use JavaW.exe instead of Java.exe. However, keep in mind that the value of using Java.exe is that if you have any uncaught exceptions, you will see them in that DOS box (or command shell, as it were). For this reason, I would leave the development environment as is (using java.exe) and not worry about the command shell window. When you are finished with development (ha!) and want to run your application separately, or if you set up a link to it, then use Javaw.exe.

Hi there !!!

I have a good solution to that .. what u can do is
1)Make a jar of ur frame application.
2)Download Nativej ver 1.0.4 from the net.
3)follow there instructions which results in a exe file of ur application
4)Double click on that exe .. ur frame is opened without a dos prompt window !!
