Java Forum / General / February 2006How to deploy Java Applications To People W/O Having To Use The Command Line?
How do you deploy Java Applications to other people? I don't think average people is gonna open up the command line and type in "java" everytime they want to run it. > How do you deploy Java Applications to other people?

The simplest way is to provide a batch file or a shell script to run the application. Web Start is an excellent method of deployment. It provides a way to auto update, inclusion of a start menu icon (and equivalent on OSX/Linux) and even provides an "Add/Remove Program" entry on windows. Here is an example... This launches a full blow Java application via WebStart. The program is regenerated once every two minutes. It is simply a JFrame containing a JButton who's label is the current date and time the application was generated. The link below shows the source of the program and a script used to generate it once every two minutes. (This example will be left up for a week or so, I'll stop the script from running that regenerates it at that point, but leave the content up) http://www.linux4real.com/java/20060211/webstart/ For a pretty good tutorial, on how to use webstart.. go to the link below. It also talks a bit about signing a jar to enable full permissions. The above I gave above doesn't allow the application delivered to have full access, it is meant to demonstrate webstart in general. Signing jars is not a complicated process and will allow a program to be deployed and auto-installed via the web *and* have as much access as required (if the user permits it). http://www.cokeandcode.com/info/webstart-howto.html btw.. The point of regenerating once every two minutes is to demonstrate the auto-update aspect. Once you click on the link once, and launch the do nothing app, click again quickly, you'll note it loads from local disk. Wait a couple minutes, click on the link again, it will be reloaded from the webstie as it as been updated. But it won't download unelss the webserver version has updates.

Infact, you'll note that my example only updates the jar, not the jnlp file (see recompile.sh content in the index.html page) On 11 Feb 2006 21:18:50 -0800, "ossie.moore@gmail.com" <ossie.moore@gmail.com> wrote, quoted or indirectly quoted someone who said : >I'll stop the script >from running that regenerates it at that point, but leave the content >up) I gather the process blows up during the jar build. You might want to build the jar then in a fast move delete and rename. That can always fail if the jar is being served. I hope to find tools that deal with this problem with FTP, by uploading, then swapping in the newly uploaded files to replace the old ones only once the whole batch is up, and only when the old files are not busy. SignatureCanadian Mind Products, Roedy Green. http://mindprod.com Java custom programming, consulting and coaching. I'm doing exactly what you state. I mentiont that i'll stop it runnign simply because i don't want to leave a script compiling a source file once every two minutes forever.
