Hi,
I agree as pointed out by Craig that the .jars of the dependent java projects should be included in your .ear as (utility jars) and your web-project and other ejb-project should not have the same in their classpath. This would ensure that your application(.ear) file when deployed should have 1 class-loader.

Hi Pradeeep,
Can you be more specific as to what you mean by start -up classes. You can
include classes as source or as .jars in your Server classpath and that is made avialable to you at start-up..

Hi Craig,
Please correct me if iam wrong. As per you the Test Server only simulates the actual WS Server on which the application has to be deployed finally and it gives once a chance to start/stop it through WSAD. In case if i want to test my application on a Remote Server I have to create an "Attach Server". In this case is it possible to start/stop the remote server through WSAD.

Hi Kylie,

1)Express server
2)Express Test Environment
3)Server
4)Test Environment
5)Express Server Attach

Hi Kylie,
I have been working on WAS 4.0 and recently WAS 5.1,but mainly on the local server which comes embeded with WSAD. I would like to know have you covered how to go for clustering the Enterprise application while deployment and what needs to be taken care during staging and production phases for the same.

Hi Prashant,
Just wondering what for you need the book so urgently that too in Canada..is there something on the cards...
Rishi

Hi Kathy,
is your book HeadFirst EJB released in India. Is it available in the stands.
Rishi

Hi Everyone,
I would be very nice if someone would share his views as to how exactly it fares and does it really performs the DMLs in an efficient manner bcoz as mentioned by everyone else i have used views only for read only purpose . Someone has worked on Weblogic on this can throw some light..

Hi Asthana,
This sounds to be why we should use Enterprise Distributed system and secondly why only J2EE or which all technology can be made use of .
.What can I accomplish with EJB and J2EE that I couldn't before? How does it influence my business in terms of profitability, reliability, availability and maintainability
Well in todays context where business consists of different parties and we cant rely on 2 tier client server based legacy system which has its own set of problems in terms of scalability, availability wherein downtime is less than 24 hrs, one would preferably go for a distributed system.

Will it reduce the programmers learning time and will it reduce the development time
As pointed out by kathy EJB has become the de-facto standard for Distributed sytems it certainly helps in learning and mastering this.
Is there a similar technilogy around like EJB and J2EE?
.Net is the distributed technology by Microsoft , but being a die hard
Java guy i only have to say this that C# which is the implementation of .Net is 99.9% Java so it doesnot matter if you know Java and EJB one can easily plug himself to .Net too

Hi All,
How can we map a single entity to two or more tables. If this be the case and if we are using optimistic locking strategy and Isolation level SERIALIZABLE it implies that the corresponding tables gets locked. Hoa far is this approach advisable.

Hi,
I think what Siva and Pradeep pointed out earlier was fair enough, one would like to expose both the local and remote interfaces and depending upon where it is deployed , either of two can be made use of.

Hi Vish,
The very notion of a transaction doed not hold good for a Entity Bean bcoz the Entity Beans are suppose to represent domain objects or more precisely
rows in database tables. In a case if there is a requirement of domain biz logic wherein you need to start a transaction it should be BMP Entity Beans
and offcourse since the container maintains a pool of entity bean instances which implies that it can be assigned to any client or it can be swapped in its POOLED state which further implies it acts like stateless. So the transaction cant be forwaded to another method.It needs to end in a single method.

Hi Prashant,
I think no one does stops you from writing "Select p from Person" . Your comment over path traversal holds good but Iam afraid not about OBJECT().
Rishi
SCJP,SCWCD,IBM OOAD

Hi All,
Can anyone explain me the significance of OBJECT() in EJB-QL. Why do we need to specify for examlpe "Select OBJECT(p) from Person" when we can also
do the same thing with "Select p from Person".
