Spring 2 Final Approching with new support for OSGi, JPA, Asynch JMS

by Floyd Marinescu on Sep 05, 2006 |
Spring 2.0 final is set to come out on September 26th - a few months after the original launch dates. InfoQ spoke to the Spring team to find out what's been going on.  Spring has been updated with JPA final spec support, asychronous JMS, the new JSP form tag library, and a collaboration with IBM, BEA, and Oracle to bring OSGi support to Spring.  The interview also goes into future directions for Spring post 2.0, and the relationship between Spring and it's many sub-projects.

Read An update on Spring 2 Final.
Since Spring 2.0 development kicked off at last year’s Spring Experience conference in December 2005, we have received a massive amount of feedback from the community. It has truly been an unbelievable response - users have not only been actively suggesting improvements, they have been performing extensive QA testing across diverse environments. This has led to major improvements to key new features such as the asynchronous JMS capabilities, the JPA support, and the new JSP form tag library. At present we are working hard to ensure sure Spring 2.0 plays nicely in an OSGi environment, something that is very important to us and our users. In addition, a large amount of effort is being invested in our documentation. The return is evident when you open the 2.0 reference manual and see just how comprehensive the coverage is.
IBM, BEA, and Oracle are also collaborating with Interface21 on the Spring-OSGi support; delivering the full OSGi integration is now a major priority for the rest of the year. The Spring team is also working on extending the JPA spec to provide a criteria-style API which could be delivered portably across JPA projects using Spring.

Criteria API (nice) by Rick Hightower

RE: The Spring team is also working on extending the JPA spec to provide a criteria-style API which could be delivered portably across JPA projects using Spring.

This is very nice. Its nice to see Interface21 innovate to what should have been part of the JPA spec. in the first place.

OSGi by Rick Hightower

What does/will the OSGi support consist of? What type of integration? Why?

Re: OSGi by Andy Jefferson

Can't speak for them but I would imagine as a minimum making all Spring jars OSGi bundles so they can be deployed in an OSGi container (in the same way as all JPOX jars are OSGi bundles and can be deployed like that). Means also that they can benefit from a plugin registry mechanism and can define extension points in Spring software and so people can easily extend it.

Re: OSGi by Adrian Colyer

You can see the full specification for what we're doing with OSGi in the attachment to JIRA issue SPR-1802.

The most recent specification version (0.7) is the attachment named spring_and_osgi_64.html. Here's a direct link.

Wrong Link by Benoit Moussaud

The link associated with "Get started with the Java Persistence Architecture (JPA) in a Spring environment." is in fact the link of "Learn about Message Driven POJOs"
Can you correct this ?
