When building a web application driven with Java, you will most likely use JSP or JSF standards with your hosting. Chances are these standards will utilize shared JVM Private servers.

The difference between public and private JVM servers is essentially the same difference between shared hosting and dedicated hosting. With a shared JVM server, you are not given access to all of the levels of administration, whereas with dedicated JVM Java hosting, you are given the flexibility to tinker with all levels of Admin. Most likely, given that Java programmers tend to be more experienced, you want to host your Java application on a private JVM server.

When developing Java applications, most programmers enjoy working in an environment that can be completely controlled to obtain the best results. With this infrastructure, you can develop a library with all the classes that you want. You can also use this development environment to change the settings for individual JVM files as well as the way that they interact with the Web server. This way you can determine the mapping involved in the Java application or even install a different version. In addition, your development environment will not be affected by shared Java servers. Often times, when using a shared JVM, you will find that the server admin doesn't have the same consistency with respect to global classes that you would have with a dedicated Java hosting server.

The probability of crashing a Java application server is high. Java programmers often run into security problems when running common JVM environments, whether they take necessary precautions or not - it's just the nature of the game.

If it's a custom application utilizing a popular Java framework, our advice is to invest in private JVM hosting that will provide you with the most stable development environment possible. Although a fully dedicated Java hosting solution may be better, cost restrictions of such a setup would be counterproductive. In any case, the search to find one that would suit all your needs would probably not even be worth the time.
