Java is one of my programming languages of choice. I always run into the problem though of distributing my application to end-users.
Giving a user a JAR is not always as user friendly as I would like and using Java WebStart requires that I maintain a web server.
What’s the best way to distribute a Java application? What if the Java application needs to install artifacts to the user’s computer? Are there any good Java installation/packaging systems out there?
There are a variety of solutions, depending on your distribution requirements.
Just use a jar. This assumes that the user has the the correct java version installed, otherwise the user will get ‘class-file format version’ exceptions. This is fine for internal distribution inside a company.
Use launch4j and an installer like NSIS. This gives you a lot more control, although the user can still do stupid stuff like un-installing the java runtime. This is probably the most popular approach, and what I currently use.
Use Webstart. This also assumes that the user has the correct java version installed, but it’s a lot easier to get going. My experience is that this is fine for tightly controlled intranet environments, but becomes a pain with larger deployments because it has some many weird failures. It may get better with the new plug-in technology in Java 1.7.
Use a native-code compiler like Excelsior JET and distribute as a executable, or wrap it up in an installer. Expensive, and it generally ties you to a slightly older version of java, and there is some pain with dynamic class-loading, but its very effective for large-scale deployment where you need to minimise your support hassles.
