What's new in Jarfix 3.0.0:
- From Java 11, Oracle does not provide a dedicated JRE anymore, only a JDK,
- therefore for x64 and JDK 9+, jarfix 3 will search for a JDK first and then for a JRE, otherwise the latest
- Java Runtime Environment could not be found if both JDK 11+ and a JRE version < 11 are being installed
- For Oracle JDK < 9 or on 32-bit platforms, the mature search strategy remains unchained
Setup installers for Windows applications are usually wrapped in an EXE file. However, some applications are dedicated to modifying other types, and file formats are abundant, even for a single type of file. The one in question here is JAR, which can easily get associated with another type of program, thus making it impossible for users to launch JAR applications by just double-clicking these files. Luckily, Jarfix comes to save the day.
Restore the JAR filetype association with Java
How To Get Jarfix
JAR files are nothing more than special executable files created by Java, which come bundled with a variety of classes and functions to make the dedicated program work. Also, Java Runtime Environment must be installed on the computer in order to run Java apps.
The problem is that some archiving utilities assume that you use JAR files to compress files into archives and, after installing these archiving utilities, they get automatically associated with JAR files, thus overwriting Java.
Fix errors made from incorrect filetype associations
In such cases, it becomes difficult for users to open JAR files with Java, unless they know how to fiddle with the Windows settings to manually change the filetype association. Users might even think that the JAR program in question is not functional just because it seemingly cannot be opened with Java.
As mentioned above, you can rely on Jarfix to solve this issue. A neat advantage that can be noticed right from the start is that you don’t have to go through any kind of trouble with an installer because this application can be run right after download. As such, you can also carry it around on an USB flash drive to restore the JAR filetype association on other computers that deal with this issue.
Double-click the downloaded file to perform the fixup
The task is finished instantly and you don’t even need to restart your computer for JAR files to revert to their default form. However, you must have administrative permissions. A small prompt appears to inform you that the operation is successful, also pointing out the location of the Java Runtime Environment program on your computer.
As suggested in the prompt, things might not work as intended the first time, but this only depends on the application that’s taking control of the JAR file. In case the problem persists, you can run Jarfix again.
Other solutions also exist but are not quite recommended for inexperienced individuals. A simple alternative is to completely remove Java Runtime Environment and reinstall it to overwrite the faulty filetype association made by the archiving tool or other software.
Simple fixer upper for JAR filetype associations
All in all, Jarfix is a nifty little repair tool that gets the job done quickly and flawlessly in most cases. It performed well under several situations and we managed to restore functionality for malfunctioning JAR files. It’s portable, doesn’t require any kind of accommodation, and can save a considerable amount of time if you really need to use a JAR program.

I have used these three open source tools for packaging my java apps, but they all look like abandon-ware now. All three are very good pieces of software.

What are the options now? (or is using Java for desktop app development no longer a 'hot' market for app developers to build & maintain these tools?).
1) exe wrapper: jsmooth - no new development in 2.5 years - does not support 64 bit. Launch4j - no new development in over a year, supports 64 bit, but you can't sign the exe created by launch4j, so I prefer jsmooth, but it does not support 64 bit. 2) onejar: It works, but there has been no new development or web site update in more than 2.5 years. So, just want to switch to something that's supported / have a backup plan if it suddenly breaks with a new build of Java. Thanks Edgar. Did you check? This is a great piece of software to create cross-platform installers: IzPack is an installers generator for the Java platform.
It produces lightweight installers that can be run on any operating system where a Java virtual machine is available. Depending on the operating system, it can be launched by a double-click or a simple 'java -jar installer.jar' on a shell. The most common use is to distribute applications for the Java platform, but you can also use it for other kinds of projects. The main benefit of IzPack is that it provides a clean and unique way of distributing a project to users using different operating systems.
Some really famous companies and projects use it for many years (Sun Microsystems, JBoss/RedHat, the Scala language project, some ObjectWeb/OW2 projects, XWiki and many more). If it's good for them, it should be good for you:). As I was fed up with recent security changes in Java Webstart, I created my own tool,. It's under GPL. It goes farther than akauppi's suggestion because it allows to create GNU Linux packages even under Mac and Windows:) I use it to create Mac bundle under GNU Linux too. For the moment, it's just a single Ant library with a few dependencies that allows to create native self-contained application bundles for GNU Linux, Mac OS X and Windows.

I use it for my first person shooter and I'm very happy with it. It bundles the JRE but it can use the system JRE if you want. P.S: JNDT is able to create a native Windows installer as an executable with NSIS even under GNU Linux. I understand that the GPL license discourages some developers to use my tool. In this case, rather use.
