There is a lot of action happening at SpringSource. Only after a week being acuqired by VMware , SpringSource bough CloudyFoundry, a year-old Oakland-based startup focused on pushing Java into the cloud.

Andi Mann, vice president of research at Enterprise Management Associates commented

SpringSource’s Enterprise Java Cloud is a service that is based on far more than merely acquiring Cloud Foundry.Certainly the functionality provided by Cloud Foundry is key, but SpringSource’s solutions for building, running and managing Java applications are ideally suited for applications that are deployed in the cloud. The new service brings this all together. For companies where the cloud deployment option makes sense, SpringSource has a killer offering.

Today they lauched Enterprise Java cloud . From their blog post SpringSource Launches the Enterprise Java Cloud. The SpringSource Cloud Foundry Enterprise Java Cloud service is available immediately at CloudFoundry.com in beta and is free to use. Normal cloud service provider fees still apply

People generally confuse with google Juice and google Guice.

Google Juice is the value that
Google gives to your site, for having a link from a good site. The value adds up for each link, and you get better search rankings

Google Guice is a lightweight dependency injection framework for Java 5 and above, brought to you by Google.

So if it is a lightweight dependency injection framework , the next question that comes to mind of programmers is it same as Spring or better than Spring ?

Google has explained the difference between Spring and Google Guice.

Guice and Spring don’t compete directly. Guice was born purely out of use cases from one of Google’s biggest applications: AdWords.

(that is a fantastic usage of dependency injection).

Spring supports two polar configuration styles: explicit configuration and auto-wiring

Guice wholly embraces annotations and generics.

So even if they both are based on principle of dependency injection , they are not same.

In a recent post on TechCrunch,  it said that Yahoo’s BOSS API could be bigger than Bing. Yahoo Boss is its open search APIs which lets developers create their own custom search engine using Yahoo’s algorithms.

Vik Singh was the brain behind’s the Yahoo BOSS API and has named top 35 young innovators of 2009.

By last May, Yahoo BOSS was serving up 30 million search queries a day but comScore doesn’t count API calls to YAhoo BOSS. That essentially means yahoo market share could be much greater than predicted based on comScore results.

Juergen Hoeller,  co-founder of the Spring framework and the most active Spring developer gave a presentation on SpringOne annual conference on what are the features in Spring which relate to Java Enterprise Edition 6. The presentation can be found at InfoQ.  Below is the link.
