Thanks, xwb, I appreciate the comment about C++.

Thanks a lot, Salem! Good food for thought. Dmitri.

Respected gurus, I have a rather theoretical series of questions. I've been dabbling with C over the years but have finally come to the point where I need to resolve some fundamental questions... (It may help you to know that I come from the Java world.) 1) From what I understand, it is...

Ingresman, Yeah, this application is for a small business, so scalability is not an issue. Thanks, all, for your insightful comments! D. P.

Does anyone have an opinion on embedded databases? Since they reside in the application server itself, it doesn't appear that traffic encryption issues are applicable here at all, no? D. P.

Ingresman, Interesting, but seems to be even more trouble than STunnel... Hmm. I wonder if there are any good (=free+functional) alternatives to MySQL that don't require you to compile anything to get traffic encryption and for which there are hopefully some JDBC drivers? D. P.

Cdlvj, I did. They give a procedure for setting up STunnel but don't answer the more philosophical questions I had in mind (#5 & #6)... D.P.

Chip, Well, I was under the impression that my EJB's would be mapped to database rows *transparently*. That is to say, as the coder I would only manipulate Java objects (EJB's) and would not see how they are stored in the database. So, if I could access all of my data through the EJBs, I...

Cdlvj, Yes, I've seen that page. It talks about how to install OpenSSL -- something that is a pain in its present form, since OpenSSL also needs to be compiled first (cf. my paragraph #3)... D. P.

Sedj, You understood me perfectly. I just wanted to see if messing with J2EE was worth it at all before taking the plunge. But now that I'm leaning toward using it anyhow, I guess your suggestion to just give it a try makes the best sense. If anyone wants to share more thoughts on the topic...

Thanks for the reply, Chip; it is getting interesting! Yet modifying DB tables directly sounds to me like getting slightly too deep "under the hood": it's easy to introduce a change into your tables that the app will fail to recognize properly afterwards... I wonder if it would instead be a...

Can anyone provide any more answers? Thanks in advance, Dmitri.

Chip, Dian, thanks for your input. But I still wonder what is the typical way to migrate data between different versions of an EJB application in the real world? I don't suppose re-entering all the data is a favorite with people? Or maybe it is but they just have a very nifty way of automating...

Thanks for your replies, guys. Let me provide the clarifications you're asking for. What J2EE technology/API do I intend to use? I was thinking about EJBs. I know that to the programmer EJBs look more or less like normal Java objects but store their fields in the rows of a back-end database...

Thanks, Eric, I suppose this answers my question #5. I only wonder if there's any *guarantee* on the TCP/IP, hardware or some other level that says that traffic between different ports on the same machine won't leave the box? I'm not sure if the second part of your answer referred to my...
