RE: Re: Error deserializing EJB-session, anyone tell me why?
Hi
I would suggest that you make the dbconnection variable transient. Would it
be better to close the database connection prior to deserializing and then
have the bean establish the connection again later.
private transient Connection dbConnection = null;
private transient ResultSet rs = null;
Regards,
Michael Mok

RE: Sybase experience anyone?
Mike Which Sybase JDBC version are you using? I think their latest stable version is 5.2 (a type 4 JDBC 2.0 compliant driver). Regards, Michael Mok -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mike Cannon-Brookes Sent: Sunday, 21 January 2001 17:57 To: Orion-Interest Subject: RE: Sybase experience anyone? I can say that we're in the process of switching our app from Sybase 11.0.3 (on Linux) to PostgreSQL. The Sybase JDBC driver was fugged for us, it locks up at about 50 concurrent connections, sending the database spiralling and grabbing more and more CPU, until Orion just gives errors with every page and Sybase sits at 100% CPU. We rectified this buy buying a commercial Sybase driver (Inet I think). For the site revamp have decided to move to PostgreSQL, seems to be performing brilliantly so far. It also has a much more active developer community, a JDBC driver that I can fix myself, and plenty of places to get support. Never tried Interbase or SapDB.

Session bean accessing other Session bean HELP!
Hi
I have just start to look at Orion and I am having problems getting my
Session bean to access my other Session bean. I wrote a servlet to access my
session which in turn calls another session bean to do something. I suspect
it must have something to do with my deployment descriptors. I really
appreciate if someone can help me out.
The error message I am getting is
