Notas del editor
- This year we expanded on that, asking more and better questions to give you better and more accurate information. The survey itself ( found here ) provided data from over 1000+ Java EE developers and those responses were analyzed to create this report. We set out to discover: We asked the people we met at JavaOne 2010, emailed previous survey respondents and promoted the survey in the media. They were sent an email with the link to the survey and told they would be notified again once the results were made available. Participants were offered a chance to win free JRebel licenses and one recipient will receive an iPad once the final results are published.
- EJB Many people consider it unnecessary difficult Entity Beans were especially problematic But even session beans earned bad reputations OSS packages mitigating the problem Hibernate instead of Entity Beans Spring as a component model They were very successful in the marketplace Many Spring/Hibernate applications Required only Tomcat to run but also work in full app servers Tomcat doesn't support JMS EJBs Other... Enterprises need integration The more mature the app is, the more likely it is to be added Add-ons It was possible to add things that Tomcat was missing But this became a “build your own Frankenstein” exercise
- The real definition of an application server in the Java EE world is more than servlets, JSP, database connection pooling. These are just a few pieces of the Java EE container model 2 , where an application is split into a server portion and a client portion 3 . The server itself is composed of different containers, each providing different services to an application. There are lots of service containers! There's the servlet container that presents the front-end user interface 4 , the Enterprise JavaBean container that (presumably) manages business logic, a naming and directory interface, a message service, an adapter service that allows access to non-Java or other non-managed services, a security container... the list goes on
- JCA : Connect EIS with application. The specification defines the contracts for an application server as well as for resource adapters, which are system-level software drivers for specific EIS resources. These standard contracts provide pluggability between application servers and EISs. JMS : Peer to peer connections( TCP, socket, CORBA, RMI) telecommunication, banking, aircraft control system, industrial,

- Offers an EAS product that matches the market definition above. The minimal EAS product is delivered by the vendor (the definitional features must be available directly from the vendor as the vendor's own intellectual property or under an OEM agreement; the extended features may be available through partners). Product maintenance and support for the minimal EAS product is available from the vendor. The vendor has been proactively offering its EAS product over the past 24 months. There must be evidence of successful production deployments (present or imminent) of the vendor's EAS offering. In 2010, the vendor generated at least $20 million of combined license and maintenance revenue from its EAS products.
