By October 2003 In the past two articles you have seen how to customize your Java application so that it looks and feels more like a native Macintosh application when running on Mac OS X without changing the end user experience on other platforms. Paragon ntfs for mac review. A combination of runtime properties and coding changes that targeted Mac OS X specific APIs made a big difference to that audience. Recall that Mac OS X is a melding of two worlds. Hard core UNIX programmers can pop open a Terminal window and write their Java code using vi and compile and run it from the command line. There is, however, the more traditional Mac audience that interacts with their computer through a friendly UI that follows Apple Human Interface guidelines. In this article, we look at deploying your Java application. To install the latest Oracle JDK (at the time of writing this answer it's Java 8u121 JDK) the various paths (besides the version number) are slightly different compared to the older JRE version. Commands that refer to filenames, as most do, assume that you’re talking about files in the working directory. When you open the Terminal window, the working directory is set to your home directory, abbreviated ~. Bash shows you the current working directory and your username to the left of its prompt. The technical geek audience might be happy with running a class with a main() method from the command line but the wider audience expects a double-clickable icon that looks and acts like every other native application. In this article, we travel from one end of the spectrum to the other to broaden your potential user base. Although you should 'test everywhere', your build machine may not be a Mac. Fortunately, as you will see, a double-clickable Macintosh application is just a directory with some special contents and a name that ends with.app. Even on a Windows machine you should be able to modify your build script to package up a Mac-specific version of your application. Primitive Distributions Because Mac OS X ships with J2SE 1.4.1 and J2SE 1.3.1, you can distribute your application as class files or jar files and - in theory - your customer could run your application from the Terminal application. We start with these models and quickly move to double-clickable jar files and shell scripts. For this article, use the as the running example. ![]() Upload avast antivirus for mac. Download and unzip the zip file. Inside the JavaSoundDemo directory you will find the source files inside of the src subdirectory, a jar file, audio files, and html files that we will not use. Can you move a transaction between accounts in quickbooks 2013 for mac. Raw Class Files As a developer, you don't think twice about compiling the source files and running the application using the command line. Compiling the eight files in the src directory generates fifty class files. You can then run the sample application from the command line like this. Java JavaSound The Java Sound Demo starts up. We haven't customized the application in any way so the menu appears at the top of the JFrame and not where Macintosh users expect. The application looks like this out of the box. (Click image to enlarge.) You have done this compile and run step so many times that you hardly think twice about it. Think of the least technical person you know and ask whether they would be likely to follow these steps to run your application if a competing application were easier to install and run. This example demonstrates two separate areas of usability. Once we got the application up and running it looked good and ran fine. You would not, however, want to distribute an application to an end user this way. You would have to somehow bundle up the fifty class files for easy download and installation. You would then have to provide instructions for running the application using, in the case of Mac OS X, the Terminal application. Jar Files If you are going to have to package up the class files for distribution anyways, you may as well produce a jar file. And, if you are going to produce a jar file, it ought to be executable. In the case of the Java Sound Demo, the file JavaSoundDemo.jar is executable. Because Mac OS X ships with the Jar Launcher application, the end user needs only double click on the jar file and the application will launch. To make the jar file executable, the manifest must include the name of the Main class file. Unjar JavaSoundDemo.jar with the command jar xvj JavaSoundDemo.jar. Here's the file META-INF/MANIFEST.MF. Manifest-Version: 1.0 Main-Class: JavaSound Created-By: 1.3.0 (Sun Microsystems Inc.) Shell Scripts and Helper Applications For larger or more complicated applications you are likely to have more than one jar file along with resource files. A common strategy for targeting multiple platforms is to include a batch file and a shell script. Choose the non-platform specific download from the homepage. Inside of the bin subdirectory you will find applications for running NetBeans on a variety of platforms. The shell script runide.sh can be run from the command line like this.
