    It's well overdue, but I've finally managed to get this stuff up. Here are the slides from my presentation on Server-Side JavaScript, as well as the source code for the Jaxer REST API provider and consumers that I wrote.

  • freedom to use the same JavaScript routines on both servers and clients. In addition, the techniques presented throughout this series will allow you to maintain a single code base for both Ajax and non-Ajax clients
  • This double-coding issue can be avoided by using JavaScript combined with Java code on the server side, getting full support of scripting languages through the javax.script API. In addition, the Java SE Development Kit (JDK) 6 already includes Mozilla's Rhino JavaScript engine, which means no setup is required.
  • the toSource() method, which all JavaScript objects must have.
  • ...5 more annotations...
  • engine.eval(scriptReader, vars);
  • sun.org.mozilla.javascript.internal.NativeObject
  • all data exchange between the Java code and the executed script should be done through primitive variables, strings, and Java objects (for example, beans) whose properties and methods can be accessed very easily in the JavaScript code. Simply said, don't try to access native JavaScript objects in your Java code. Use Java objects in the JavaScript code instead.
  • Note that javax.script.Invocable is an optional interface, which some script engines may not implement. The JavaScript engine that comes with JDK 6 does support this interface.
  • you can significantly reduce the execution time by compiling the scripts, using the methods provided by another optional interface named javax.script.Compilable, which is supported by the JavaScript engine of JDK 6.
