Hi, I am trying to find an article or post that could answer the 'Why bother to add Spring to Jboss' question. I did read This and that explains how, not why. We have an existing J2EE application running in Jboss and other developers are planning to convert it to Spring. I think they are doing it wrong and destroying the J2EE design pattern but I need to understand Spring to steer them in the correct direction. Is there any benefit in changing an MBean service into a Spring bean? I can see no point in this. Thanks, Ken View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078039#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
