Lastest News: DirectJNgine 2.1 for ExtJs 4.1.x is out!

DirectJNgine 2.1 final is out, providing support for ExtJs 4.1.0. You can get it from the downloads section!

We highly recommend you upgrade to ExtJs 4.1 if at all possible, as it a major improvement to the 4.0.x version.

What is DirectJNgine?

DirectJNgine (or DJN, for short), is a Java based implementation of the Ext Direct API for ExtJs.

ExtJs is probably one of the most powerful and attractive UIs for web-based applications, as can be seen here, as well as in many other examples. DirectJNgine makes it much easier to use the full power of Java business classes with such a powerful front-end, making Java methods directly callable from the client.

DirectJNgine is fully feature complete, providing support for all kinds of requests: batched json requests, form posts with file uploads, requests from polling providers, etc.

A detailed User's Guide (more than 40 pages) is part of the distribution. Besides, it runs all of Ext Direct examples distributed with ExtJs 3.0, located in examples/direct, and additional demos are included and discussed in the User's Guide.

DirectJNgine is extensively tested, passing more than 90 automated tests for all supported web browsers (see the list below).

For further info, take a look at the User's Guide.
