I recently had the pleasure of chatting with Rod Johnson for JavaWorld’s Java Technology Insider regarding all things Spring, baby. Spring has come a long way since its early days; in fact, a recent study shows spring adoption reaching 73% of Java development shops; plus, SpringSource, the commercial entity behind Spring, recently, acquired G2One (the entity behind Groovy and Grails). In this conversation, Rod discusses how SpringSource walks the line between commercial success and its driving role in open source projects such as the Spring framework and Tomcat. Similarly, he explains what factors might cause developers to migrate from Spring’s strictly free and open source products to the commercial, and costly, SpringSource Enterprise package. He also chats about the new, OSGi-based SpringSource Application Platform, which Rod says is designed not for where the Java enterprise market has been, but for where it is going.All in all, I had a great time learning from Rod and I hope you pick up a nugget or two listening to him as well, baby!
