Hi all
What is difference between
javabeans with response scope and session scope
in jsp.
Are javabeans with response scope lightweight
and are ready for garbage collection
immediately after every response.

Hi all
As per EJB 1.1 in entity beans the instances are pooled
and can be reused.
Then as per specs I understand that if max pool size is
reached and the there certain non-locked instances in
pool and if client tries to create entity bean then
container should reused this instances and associate it
to EJBobject.
But I have observed that in Weblogic 5.1 if pool is full
and new entity bean is created,
Container passivates one of the instances, calls
unsetEntityContext, removes instance from pool
and creates new instance for entity bean class.
Is this the expected behaviour or is weblogic not
following the specs or i am going wrong

Thanks in advance

How about passing/returning Vector objects instead of 10 parameters.
Will overhead reduce on passing Vector objects ???

hi all
I would like to have opinion from everybody.
After hearing stories about java fall down,I am bit
confused whether to go ahead with my J2EE studies.
I know that market in general has gone down.
But will it be worth to invest in J2EE certification
as some predict rise of J2EE after market moves parallel
to y-axis.

Thanks in advance.

Hi all
Does EJBHome in EJB uses Factory pattern or
Abstract Factory ?
I think it uses Factory pattern, because
Abstract factory is one who returns factory object.
and EJBHome returns EJBObject which is not factory object.
Am I on right track or wrong.
Thanks in advance.

Consider following scenario
Applet is downloaded from web server behind the firewall having HTTP proxy configration.
Now is it possible for this applet to create database connection across firewall(Assume database is on webserver itself).
