So, you've written a "Hello world!" WebSocket application or perhaps even a chat sample. You're able to exchange messages even in pre-Servlet 3.1 containers and pre-IE 10 browsers (that don't yet support WebSocket) thanks to the SockJS protocol and Spring's support for it. However a message is a blank page that can have any content. Whatever message format you choose, proprietary or standard, both client and server need to understand it as well as distinguish different kinds of messages. You need support for the publish-subscribe pattern central to messaging applications so you can broadcast messages to one or more subscribers. You need to incorporate security, validation, and so on. In short you need to build a real-world application. If you're used to web applications (and Spring MVC annotated controllers) you are familiar with the foundation that HTTP provides including URLs (nouns), HTTP methods (verbs), headers, parameters, and others. Imagine building an application without HTTP, just a socket. WebSocket gives you this brand new, exciting capability -- full duplex, two-way communication -- yet you no longer have an application-level protocol. Can an entire application be built around a single Endpoint class processing all messages, assuming a single WebSocket connection between browser and server? Join Rossen Stoyanchev as he demonstrates that, thankfully, the WebSocket protocol has a built-in sub-protocol mechanism.

At Pivotal we are bringing two open source projects together -- Hadoop and the very rapid and widely used Spring java application development framework to help build Big Data Applications. While Hadoop is proving to be the defacto foundation for storing and processing data, real-world scenarios require much more. Millions of developers are already using Spring to create high performing, easily testable, reusable code without any lock-in. In this month's webinar James Williams will explore how Spring XD (Xtreme Data) is addressing Big Data Application needs including:

• High throughput distributed data ingestion into HDFS from a variety of input sources
• Real-time analytics at ingestion time, e.g. gathering metrics and counting values
• Hadoop workflow management via batch jobs
• High throughput data export, e.g. from HDFS to a RDBMS or NoSQL database.

Hello everyone! Pieter posting this on Josh Long's behalf here... this week the Spring and Cloud Foundry teams are at JavaOne talking to developers about Spring, Cloud Foundry, Hadoop and big data! Happily, our pretty new @GoPivotal booth has garnered a lot of attention!

I met Duke, too! I think the big guy was as happy to see me as I was him!

1. Spring ninja Greg Turnquist put together a nice post on how to contribute to Spring Boot with a pull request. The article does ultimately talk about the processing sending a pull request, but most of it's a really great introduction to extending Spring Boot to suit a new use case (like JMS, which simply hadn't been added yet). This post also introduces some cool features in Spring Boot, if you haven't learned about it yet.
2. Speaking of Spring Boot, check out this upcoming Spring Boot webinar featuring project co-lead Phil Webb!
3. Rossen Stoyanchev put together a knock-out piece how to build web applications that use websockets, or Sock.js, and how to then layer STOMP on top of that for an easier messaging-style interaction between the browser and the service.
4. Rossen also has an upcoming webinar on Oct 8th, Building WebSocket Browser Applications with Spring, showing off the best of his SpringOne2GX 2013 session.
5. I encourage you to check out the upcoming webinar featuring James Williams on building big data applications with Spring, Spring XD and Hadoop! This is going to be an awesome talk. James has some killer examples and knows his stuff.
6. In related news, I put together a quick post on my thoughts on Data Integration, Stream Processing and Spring XD.
7. Jakub Kubrynski has put together a nice post on how to use load-time weaving to inject dependencies into objects not managed by the Spring container using a couple of different approaches.
8. Nitin Kumar put together a nice look at Spring Integration, a lightweight approach.
9. Tomás Lin, who says that he loves testing Grails applications with Spock, put together a great post on how to test with Spring Boot with Spock.
10. Sometimes, you need to do RMI, and when you do, Spring has you covered!
11. The BitwiseOR blog has a great post on how to use Spring Boot to build REST services, using Groovy no less! Win! I'm not sure if I agree with the conclusion, but whatever it takes for people to be able to use this to simplify development, it's a win! And, with really great posts like this, hopefully it won't be long at all before everyone's bootstrapping their development, too!

In case you missed this year's SpringOne 2GX conference, one of the hot keynote items was the announcement of Spring Boot. Dave Syer showed how to rapidly create a Spring MVC app with code that would fit inside a single tweet. In this blog entry, I will peel back the covers of Spring Boot and show you how it works by putting together a pull request.

Autoconfiguration

Spring Boot has a powerful autoconfiguration feature. When it detects certain things on the classpath, it automatically creates beans. But one feature it doesn't yet have is support for Spring JMS. I need that feature!

The first…

Are you fed up with searching stackoverflow for copy-paste configuration, do you want to write apps that can 'just run'? Perhaps you are just starting out with Spring and want a quick way to learn the basics without manually downloading and installing half the Internet?

In this webinar Phil Webb will demonstrate how Spring Boot can take you from zero to Spring with minimal fuss. We will look at how you can rapidly prototype Spring applications using Groovy, and how Spring Configuration in Java applications can be radically simpler. We will show how you can embed tomcat into your applications…

Roy Clarkson (@royclarkson) and I gave a talk at SpringOne2GX 2013 in which we talked about building REST services with an eye towards consuming those services on mobile platforms like Android and iOS. This talk demonstrates the progressive evolution of an application using Spring MVC, Spring HATEOAS, Spring Data REST, Spring Security, Spring Security OAuth, and Spring Android. The code's benefited from a lot of help from Rob Winch,

Layout of the Code

The code for the talk is on my GitHub account (github.com/joshlong/the-spring-rest-stack). Importantly, the code lives in the code directory. Beneath that there are two choices: web (where you'll find the rest, hateoas, hateoas-data, and oauth, social modules) and client (where you can load the Android module and the iOS module). The modules in the web folder in respective order, demonstrate the evolution of a simple REST service which incorporates hypermedia, Spring Data repositories and OAuth security. The social…

Hot on the heals of the Spring Data Babbage GA release I am happy to announce the availability of two community driven Spring Data modules, namely the first milestone of Spring Data Couchbase lead by Michael Nitschinger and the 1.0 GA of Spring Data Solr lead by Christoph Strobl.

The first milestone release of the Couchbase module contains lots of features that allow you to build content driven and scalable applications on top of Couchbase and spring-data very quickly. This release features support for templates, repositories, Java and XML-style configuration. Entities are automatically converted into JSON documents, which can be queried from Couchbase and exported through scalable map/reduce views. In addition to that, the release contains support for @Cacheable…

Dear Spring community,

I am happy to announce the first milestone release 3.4.0.M1 of the Spring Tool Suite (STS) and the Groovy/Grails Tool Suite (GGTS).

Highlights from this milestone build include:

• import new Getting Started guides directly into the IDE
• new wizard to start with Spring Boot directly from within the IDE
• automatic detection for JavaConfig classes
• basic support for Groovy in Spring IDE
• updated to Eclipse Kepler SR1 (RC1)
• updated to Grails 2.2.4
• updated to tc Server 2.9.3

Both tool suites ship on top of the latest Eclipse Kepler SR1 RC builds.

The 3.4.0. release is scheduled for early October 2013 - shortly after the Eclipse Kepler SR1 release.

To download the distributions, please go visit:

• Spring Tool Suite: https://spring.io/tools/sts/all
• Groovy/Grails Tool Suite: https://spring.io/tools/ggts/all

Detailed new and noteworthy notes can be found here: STS/GGTS 3.4.0.M1 New & Noteworthy.

Enjoy!
