Hi
The more I study the J2EE technology, the more I
wonder why I should use it.
The main reasons why I would use it are these:
- Forget about the database layer while only using CMP
entity beans.
- Faster.
- Scalable.
- Easier to manage transactions.
- Clear separation between
I am not sure because I tried it long time ago, but in my case this was
caused by copy-paste operation on cert in my Explorer5 window. When I
changed encoding in my Explorer5 settings it was O.K.

Furthermore, I received my bugzilla account password and already entered our

Thumbs up for orion for the quick response.

Hi!
I fully agree with your opinion.
We in our company have decided to use ONLY stateful session beans(SSB) for
database access. Yes, it is necessary to create some proprietary persistence
stuff, but we see a lot of benefit from it mainly because there is only one
instance of SSB per database

With 1.4.5, I'm having some timing issues with autostarted application
