The biggest issues with Java itself is the data conversion. EBCDIC->ASCII, character to String, and especially numeric to BigDecimal, all of these cost a lot in terms of ovberhead. The BigDecimal class is a notoriously poor performer (so bad that IBM created its own). EJB adds a whole new level of overhead. Since the entire bean needs to be populated, that means you have to convert every field, even if you don't need it. At least with a JDBC approach you can convert only those fields you are using. With EJB, you have to convert the entire customer master in order to access a single flag. Most Java programmers have no clue about this, and since they tend to test on dedicated fast Wintel machines with lots of RAM, the problems don't actually show up until they make it to production.
