I'm interested on the first way to intregate Spring and EJB3.
I have tried it in a example project buy it doesn't run. I'm searching since many time a solution,but nothing.
I have posted on Spring forum,but no one seems can help me.
I appreciate if you can help me.Thank you

Yahoo! SVP Shelton Shugar, speaking at the 4th International Cloud Computing Expo, outlined some of the detail involved in serving 600 million users per month while handling hundreds of petabytes of data.
"We are building a private cloud to be used within Yahoo!," he said. Hundreds of applications have already been migrated to the cloud, he said, noting that "we are (now) focusing on the data processing environment and serving environment."
"This is a long-term activity. started a few years ago," Shugar said. "And prior to cloud we might have had to literally forklift machines and move them when we want to move capacity. With cloud serving we are building a flat network and can basically point and click and move capacity from one place to another."
Shugar outlined five areas of emphasis:
Edge services - where the company deploys around the edges of the netwrok to speed content delivery.
Cloud serving - involves hosting applications. automated provisioning, and "we allow through a declarative language to define an app through tiers of an architecture," Shugar said. "Tiers can be as big or small as you need and can adjust over time. We can use the language to define connectivity, and can clone a collection of tiers."
Storage - All of the online servers have RESTful APIs, "so are easy to use," Shugar said. "We can support a variety of consistency models, and there's a lot of similarity between and among our services." He also mentioned the company's "MOBstore" (mass object store) capability, which takes objects ranging in size from a megabyte to a couple of gigabytes, which are assumed to be immutable. He also noted the use of the company's "Sherpa" funcitonality," so I dont' have legions of developers trying their own schemas, etc. They write a few API calls and it's done," he said. "It's a great way to drive innovation."
Batch processing - This is the data warehouse, and where Hadoop comes into play. "We started developing this a few years ago, and ran on about 20 machines," Shugar said. "Today we run on tens of thousands of machines, with 80 petabytes of storage. We have upwards of 1000 people trained on it, and hundreds of applications on it. It let's us pull together thousands of computers and say hey 'you're one file.'"
Shugar also described "a new language called PIG (not an acryonm) that's a higher-level procedural language. The amount of code you write is very small, while adding metadata, workflow, data management, etc."
Data collection - "This is a set of services that allow us to collect content from our web servers, platforms, and search," Shugar said.. "It cleans it up all the data, pulls out out the bot traffic, etc."
Shugar went on to provide some use cases. One example was the home page. As Shugar noted, "when you type in yahoo.com you are going through our cloud. We look at user behavior through Hadoop and determine which are the most interesting articles for folks, a feedback loop to improve the consumer experience by selecting content the consumer is interested in." Through this method, "clickthroughs are up," Shugar said. "The consumers win because they get what they want, we win because we get more advertising."
