This Friday at OSCON 2012 I’ll be doing a presentation about Client/Server Apps with HTML5 and Java. Here is the session description:
The web application landscape is rapidly shifting back to a Client/Server architecture. This time around the Client is JavaScript, HTML, and CSS in the browser. The tools and deployment techniques for these types of applications are abundant and fragmented. This session will teach you how to pull together jQuery, LESS, Twitter Bootstrap, and some CoffeeScript to build the Client.
Tomorrow, May 30th, I will be co-hosting a webinar about Social Enterprise Java Apps on Heroku. The webinar will be at both 2:00 p.m. GMT and 10:00 a.m. PDT. Register at: http://www.developerforce.com/events/webinars/2012-05-30/registration.php?d=70130000000sW7g
Here is the description:
In this webinar you will learn how to build Social Enterprise applications using Salesforce.com, Heroku, and Java. Through live coding and demonstrations you will learn how to instantly deploy and scale Java apps on the cloud with Heroku.
Update: This tutorial is a bit old. For more up-to-date tutorials see: https://www.playframework.com/documentation/2.3.x/Tutorials
I’ve created a Play 2 Tutorial and posted it on GitHub! The tutorial covers how to:
Create a Play App Set up an IDE Start the Play Server Routes Test a Route Update a Controller Test a Controller Update a View Test a View Deploy your app on the Cloud with Heroku Create a Model Create UI for Adding Tasks Get Tasks as JSON Display the Tasks via CoffeeScript and jQuery Make the App Pretty with Twitter Bootstrap Add Form Validation Update the App on Heroku Each section has a corresponding branch in git so you can diff against my version to see if you’ve done everything correctly.
Over the next couple weeks I’ll be doing two Java User Group presentations, a Flash Platform User Group presentation and one Webinar. Hope to see you at one of these events:
Wednesday May 9 - Denver Java User Group:
Running Java, Play! and Scala Apps in the Cloud
Thursday May 10 - Webinar hosted by Neo4j:
Graphs in the Cloud: Neo4j and Heroku Tuesday May 15 - Atlanta Java User Group:
This week I’ll be doing two presentation about Heroku:
Tuesday May 1 - 5:30 PM at the Denver Open Source Users Group:
Heroku Cloud Computing Platform Thursday May 3 - 12:25pm at Future Insights Live (Las Vegas):
Client/Server Apps with HTML5 and Java Hope to see you there!
Last week I announced the WebJars project that allows you to specify your web libraries (JavaScript, CSS, etc) as dependencies in your Java web applications. With some help from Jeremy Grelle I was able to get a simple WebJars Spring MVC example working.
First you will need to add the WebJars repository to your build. For Maven, just add the following to your “pom.xml” build file:
<repositories> <repository> <id>webjars</id> <url>http://webjars.github.com/m2</url> </repository> </repositories> Then add a WebJar dependency, like Twitter Bootstrap:
Update: I’ve created a Spring MVC WebJars example.
Update 2: Ukrainian translation here - http://softdroid.net/vvedennya-webjars by Eclipse Android.
Update 3: WebJars.org has been officially launched! Learn more.
Our web apps are using more and more web libraries like jQuery, Backbone.js and Twitter Bootstrap. The traditional way to use those libraries is to locate & download the JavaScript and CSS source then just copy it into a project. To me this resembles how we used to just copy JAR files into a project’s WEB-INF/lib dir.
This week I will be presenting about Running Java, Scala, and Play apps on Heroku at the Houston JUG and at No Fluff Just Stuff in Reston, VA:
