Seo Master present to you: Two years ago, Bob Lee and Kevin Bourrillion open sourced Google Guice 1.0, a lightweight Java dependency injection framework. Guice takes the pain out of writing and maintaining Java applications big and small. Guice has gained a great deal of traction both inside and outside of Google. Almost every Java-based application at Google is also a Guice-based application; the list includes AdWords, Google Docs, Gmail, and even YouTube. Open source users run Guice in everything from file-sharing software to ATMs. They've even written two books about this Jolt-award-winning framework.

Today, we're releasing Guice 2. The minimally-sized API extensions introduced by Guice 2 will have a majorly positive impact on the size and maintainability of your code. We closely scrutinized each addition, carefully balancing maintainability and flexibility. Here are a few of my favorite new features:

• Provider methods eliminate the boilerplate of manually-constructed dependencies.
• Module overrides allow you to tweak a production module for a unit test or QA deployment.
• Private modules enable compartmentalized configuration, simplifying module reuse.

Guice works with Java SE, Java EE, Google App Engine, Android, and even Google Web Toolkit (via GIN).

Seo Master present to you: This post is part of the Who's @ Google I/O, a series of blog posts that give a closer look at developers who'll be speaking or demoing at Google I/O. This guest post is written by Mani Doraisamy from OrangeScape who will be demoing as part of the Developer Sandbox.

Google App Engine took two bold steps in the right direction for cloud computing in making its datastore distributed to ensure scalability and durability and in fixing its architecture to be stateless to ensure failover and availability. To quote Henry Ford: "Any customer can have any application that is scalable so long as he builds for this fixed architecture."

To date, it has worked very well with the social web app companies, but the enterprise application development community has mostly stayed away from Google App Engine for three reasons:

• “Newness” to Google App Engine's concepts of GQL, lack of aggregate queries, denormalized schema.
• Lack of transaction support: commit or rollback on distributed storage and read consistency within transaction scope.
• Relying only on the cloud: not being able to run the same application on standard infrastructure inside your company.

Now you can build business applications on Google App Engine, too! OrangeScape is a Platform-as-a-Service for building business applications that run both on the cloud via Google App Engine and in your data center.

It has three main benefits:

• It provides a modeling environment to build business processes and rules, datamodel using a familiar process design and spreadsheet like interface. The application that you build on this interface can be deployed on Google App Engine in a single click.
• It enhances the persistence layer of Google App Engine to support transactions and read consistency on BigTable. It makes it so transparent that there is absolutely no difference for you to build applications on BigTable or on relational databases.
• If you are a solution provider building business applications today, you may not know if all your customers will accept running applications on the cloud. Some might expect that applications run on their data center. With OrangeScape, you can build it once and run it on both - cloud and data center.

If you are excited to try it out, bookmark http://trial.orangescape.com/. We will making the public beta announcement shortly after Google I/O.
