I downloaded the JDK from java.sun.com.  In dos I am using the command java application to run the application.  When the application runs the dos window is still open and shows all my debug statements.  My question is, does anyone know how to hide that dos window while my application is running.  I actually have an icon on my desktop whick I click and then calls a batch file to start off the java application. Is it even possible to hide that dow window and still allow my java application to run?

Have you tried javaw from the distribution? That is exactly the purpose for which it is intended.

You can archive your program .class files into an executable JAR file. On double-clicking the JAR file icon, the program will run. Here is how you create the JAR file. First, create a manifest file, say "test.mf", with the content as follows:

Main-Class: MyClass

MyClass is the name of the class which contains your static main() method. Note that there must be a newline character at the end of the line.

Then archive all the files as follows:

jar cmf0 test.mf Test.jar *.class

where Test.jar is the name of the JAR file, and *.class means all the .class files in the current directory.

Now that you have the JAR file, all you need to run it is to double-click its icon.

  mfcrusty, I would actually go with the solution jim_cakalic has suggested.

Thanks Jim.  I never knew what that was for.  I am a Java certified programmer and I never used javaw.  I always wondered what that command did but it was never required of me to use it.  Thanks again.

S'okay. There's more there than any of us can possibly remember.
