Powered by an Ahead-Of-Time (AOT) compilation, Excelsior JET enables developers to pre-compile Web applications (WAR files), as well as the Tomcat server and third-party libraries, into a native code executable and avoid the distribution of the easy-to-hack Java class files altogether.
Jason Brittain, co-author of the best-selling "Tomcat: The Definitive Guide" book, has recommended Excelsior's solution for increasing the security of Java Web applications: "When compiled into native code with Excelsior JET, none of these class decompilation tools work, and the Java program still runs the same. I tried JET 7 with Tomcat 6 and some of my own large and complex web applications, and it worked flawlessly! I was able to natively compile my Tomcat and my webapps into native code that installed and ran just fine. I was also pleasantly surprised at how easy it was to compile it all on the first try. From my tests, JET works great."
Supported version of Apache Tomcat: 5.0, 5.5, and 6.0
