Hi, Actually your application is 'tailored made' for a middleware environment. And note, but because it is a POJO now doesn't mean you have to give that up. There are varying ways to mainting POJO development in the context of an applcation server. Interestingly enough, your application if ported would more like as not touch on just about every aspect of an EE environment EJB -component model if you wanted declarative transactions and what not JCA (or JBossRemoting) for bi-directional connectivity to the foreign host JDBC -which is really JCA, for connection pools etc So, it sounds like a pretty interesting project. Again, you wouldn't necessarily to a full scale port where you would lose the work you have already invested so no loss there.
