David, this is a general Java development question, not specific to GeoTools. There are many ways to create something runnable. The basic problem is that you need to package your .class files into a runnable .jar file, and also ensure that all dependencies are available at runtime on the classpath. You also need a JRE (your JDK comes with one, other users will need one).
In Eclipse you should be able to File/Export/Java/Runnable JAR file and bundle all your dependencies into the JAR. http://www.google.com/search?q=eclipse+runnable+jar+file+tutorial This is crude and unsuitable for real applications because it makes it hard to manage dependencies (and comply with the LGPL), but might be suitable for experimentation. For real applications, there are open source installers that bundle your runnable JAR, its dependencies, scripts, and even a JRE. I have used izPack (but that was years ago). There are others: http://stackoverflow.com/questions/184060/java-application-installers http://www.google.com/search?q=java+application+installer JEE servlets have their own deployment technology: WAR files; These can be generated by Maven and Eclipse. Other platforms like Eclipse RCP have their own patterns. Kind regards, Ben.
