XMLVM cross-compiles byte code instructions from Sun Microsystem's virtual machine and Microsoft's Common Language Runtime. A Java class file or a .NET executable is first translated to an XML-document. Based on the XML-document generated by the front-end, various transformations are possible. The first transformation cross-compiles from .NET to JVM byte code. Another transformation enables Java or .NET applications to be cross-compiled to JavaScript so that they can run as AJAX applications in any browser. Yet another transformation allows to cross-compile a Java program to Objective-C to create a native iPhone application. You can even cross compile an Android application to run on the iPhone!

JiCal can rip through your users home directories, find iCalendars that have been stored from evolution (ie Ximian.org) and convert them to free busy files for serving from your webserver.

Good explanation of the different Java distributions and VMs (CDC, CLDC, Micro etc.)

The Java ClassBuilder is a simple framework for bytecode transformation of existing Java classes, in order to make them easily usable for data binding (and other uses) when developing Java desktop applications. Although the ClassBuilder is a (very lightweight) framework, it's focus is on a set of ready out-of-the-box solutions that aim to bring easy to use data binding to the Java platform. Under the hood it uses the amazing Javassist bytecode transformation library to change the structure of Java classes at runtime. Let's repeat: the focus of the ClassBuilder is not on providing a framework (there's enough of those already), but providing ready-to-use solutions that utilize it under the hood. private JTextField fName = new JTextField(); private JTextField lName = new JTextField(); @Property @Bindable private Person person = new Person(); @Property @Bindable private String fullName = ""; //create bindings Binder.bind(fName,"text", this, "person.firstName"); Binder.bind(lName,"text", this, "person.lastName"); Binder.bind(this, "${person.firstName} ${person.lastName}", this, "fullName");

The developers of the Java language tried their best to stop us from constructing our own enum instances. However, for testing purposes, it can be useful to temporarily add new enum instances to the system. In this newsletter we show how we can do this using the classes in sun.reflect. In addition, we use a similar technique to modify static final fields, which we need to do if we want the switch statements to still work with our new enums.
