I suspect that if you do this Eric, it won't compile...
It compiles fine, and works fine too. But I haven't testing it in a
multiuser environment yet.

If I comment out the init() method in my servlet do I get an instance of it
for each request?
I misunderstood. You want many users to use the same bean to get common
information, kind of like a message board. each user works
independently, but they are using a common bean.
someone else said "If it is the latter, then just use local variables in
your bean methods."

What's the meaning of JMS? I'm not sure my problem is just what you said. I
want to get independent instance or the same bean for each user. So they can
work independently, and won't infl

One common technique to solve this is to use JMS. All beans that are
instances of the same user listen to the same topic. when one instance
of the user's bean is updated, the other instances are notified. Each
bean then goes to the database to refresh itself.

Hello guys,
i expect beans and servlets to behave different?
As i know servlets should only be instanced once in the servlet
container, and each request should be handled by the same instance of
the servlet. To handle different data for different users, you need to
use session tracking and sto
ages where I question the fundamental understanding. I must go read the
servlet API I think.

Hi,
When two users call the bean almost at the same time, it seems that they share the
same object and their implementing is dependent with each other (I hope they are
independent), and cannot get correct results. Should I configure Tomcat? I think the
java bean is no problem. It's urgent. Plea
