Bye, bye BEA: From Weblogic/EJB/CMP to Tomcat/Hivemind/Hibernate

... and loosing some 1700 loc on the way (counting only Java, disregarding evil xml-deployment-descriptors). Our first non-trivial App on Hivemind/Hibernate is now productive for 5 weeks. No technical problems so far, just the usual buggies associated with cleaning up only part of a design-mess. The whole thing was never really performance-critical (only some 2000 transactions per workday), but only reducing db-hits dramatically using hibernates 2nd level cache made it at all possible to move the app some 400 km away from its underlying database.
