[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-255) Remoting capabilities

[ http://opensource.atlassian.com/projects/hibernate/browse/EJB-255?page=co... ] Emmanuel Bernard commented on EJB-255: -------------------------------------- Hi Dimitry Of course you can tunnel your JDBC calls through whatever protocol you want, so the firewalls is not the issue, neither is the communication breach since it can be crypted. Note that those problems are *exactly* the same for a remote EM. You somehow need a key/password on the client side to communicate safely to the server, be it remote EM or remote JDBC so both need configuration. As for business security (what you call service method security): if you open the EM, you have access to all operations available on mapped objects, this is very close to what you can do in plain JDBC (esp since the EM can give you back access to JDBC anyway). True business methods, with limited operations are interesting for security but then you no longer need a remote EM. Transactions issues would be fine if Hibernate was used locally with a remote JDBC call, this is solved by the conversation scoped persistence context. I don't see the benefit to create a delta object change mechanism (this is already what Hibernate do when it talks to the DB :-) ) joins transfers more data than a PC diff, but it also requires to keep a copy of this PC at the server side hence consume more resources, plus using a Persistence Context + lazy loading + subselect + batch-size minimise those issues, this is not an obvious choice :-) SCA seems to suffer from the reinventing the wheel syndrome to me, I don't have strong opinions on SDO, though. I'm not saying that a remote PC is a bad idea, I'm saying that it's not as good as it first sounds, and the good usecases are not that large. I reckon the traffic size and latency is something that needs to be addressed. I tend to like XUL over NetBeans/Eclipse as a rich platform approach, but I'm not an expert in that field.
