J2ObjC: A Java to iOS Objective-C translator by Google

Its a joke. It translates Java to Objective-C code without GC support (uses reference counting which you need to annotate). It doesn't define any UI so effectively you need to work on a Mac just without all the wonderful tools for UI building that apple provides and without any of the WORA you get from Java. When something doesn't work you are still stuck debugging in Objective-C. And googling stack overflow trying to understand how to translate Objective-C code to your problem.<p>Codename One solves all of the above issues by giving "actual WORA" which is the true value of Java.

To save time for those who won't read the wiki:<p>This is not a tool to convert Java apps to iOS apps. This is a tool that helps you write <i>business logic</i> in one language so it can be shared without duplication between Android, web (via GWT), and iOS apps. Write your presentation logic with the native tools, ie. Interface Builder, etc. Cross-platform mobile UI support is explicitly avoided. Xcode is great--use it!

This seems a lot like a rebrand of XMLVM (<a href="http://xmlvm.org/overview/" rel="nofollow">http://xmlvm.org/overview/</a> -- also a Google-employee-run project) with some missing UI features.
