Java and UI: Sencha GXT & Modularization

Two developer talks

Java and UI: Sencha GXT

Sencha GXT is a JavaScript front end that is written in java but compiled to JavaScript. It is built on the google get framework and has solid server communications protocols such as asynchronous call as well as RPC. However instead of using the get front end library it has it own rich UI library. It also includes a charting library. Java developers often struggle with non-java front ends such as JavaScript etc. CMX build an RIA for the financial industry using gxt. As the feedback was very positive. If its of interest to your members I'd be willing to provide a full demo walk through of our experience using Sencha GXT including pros and cons.

time.  He holds a BS in Electrical Engineering for Northeastern and a

Java and UI: Modularization

HTTP wasn't designed for high volume. Modularizing web applications can take you to a place where you'll have a bunch of small (<100bytes) javascript and css files. To optimize file transfer and avoid multiple HTTP requests you can use a build process to concatenate and minify your files or write a servlet to do it during runtime. This presentation  will show both approaches and discuss what are the pros and cons for each one.

Vinicius Isola is an experienced Java developer who has worked on many different types of projects, from server side to mobile applications. He spend a lot of his spare time researching web application design, modularization and optimization.
