Hi all
I am using MSSqlserver2000 with the microsoft jdbc driver, but I need two datasource, iPlanet told me that I should use the XADataSource if I wanna use global transaction for my two datasource, but microsoft jdbc driver does not support the XADataSource object.
What should I do ? What the String will be when I register the Microsoft driver? Does iPlanet has the implemetation itself? If so, what it will be ?
Greate thanks

Hi, all :
I am facing a problem that I am building a ear which contains several ejbs (my.ear contains aEJB.jar and bEJB.jar) and I have put some common utils into the classes folder in the ear (my.ear\classes), but it seems neither aEJB.jar or bEJB.jar could visit it.
Could anyone here give me a hand ? Does that means if the common utils that both aEJB and bEJB use should be copied into aEJB.jar and bEJB.jar ?
Thanks.

I think you could use facade to maitain the security of your entities, I mean one remote session and serveral local entities
Hi, all
In petStore, Sun let the session bean to look up the DAOS, in my opinion, the difference of lookup and import is that if the daos and ejbs will be put on one server machine or not. Am I right? Cause Lookup waster much more time than import, so I if I just put the ejbs and daos into one server machine, it is not necessary to look up daos or such resource, am I right?
Hi, all
