http://www.siliconvalley.com/mld/siliconvalley/news/local/3449853.htm As far as I know, Bluestone's not free, and even if it was, I'm not aware of any stellar features that would make it good to adopt at this stage in its life. Any Bluestone fans out there who know otherwise, please tell me. If you're looking specifically for free J2EE, two I know of are JOnAS (http://www.objectweb.org) and JBoss (http://www.jboss.org). JOnAS is entirely free and claims better performance, but JBoss has been better integrated with JSP/Servlet containers such as Tomcat. You do have to pay if you want up-to-date manuals, however. There are other systems as well. Orion is popular, though you have to pay for commercial use, if I remember correctly.
Customer surveys are for companies who didn't pay proper attention to begin with.
