Enthuware is not a book , it is a program that provides mock tests. You can go to Enthuware.com and search for your certification exam.

Hi Anotida ,

In addition to the book I would also recommend Enthuware tests. Have you tried them before.

I passed OCPJava 8 Programmer 2 with 80%. My experience with the exam was I found it harder than expected. I came out not sure if I would pass, but the result made me glad. I feel there was lot of ambiguity in the questions, kind of making me unsure if i had got things right or not. There were lots of questions on streams, did not get any at all on Serialization.

Thanks to Jeanne Boyarsky and Scott Selikoff for the book and the creators of Enthuware. I started out with reading the book cover to cover and then started doing the Enthuware tests. My average on Enthuware were in the 70 range, I got a few 80s as well. Got a 65% on the final mock test, which spurred me to start reviewing the book, spent the last week reading the book again which I think helped.

Regards

Thanks for the reply Tim. Question, is would you get better performance, if the code was compiled with JDK 7 while running JRE 7 , as opposed to compiled with JDK 6 and running JRE 7.

We are planning to upgrade from JRE 6 to JRE 7. Will running the existing code, compiled with JDK 6.0, be less performant than compiling with JDK 7.0. Any links on the topic will be helpful.

Thanks

Storing in a hashmap, would make it accessible only if the next request goes to the same instance, the hashmap store was done in.
If I have 10 instances of a APP server ( lets say distributed among 5 physical servers ) - it would not work.
Anastasia,

I think in (1) you are talking about sending all the information in the request itself.
(2) - saving in a session on the server, is what Iam trying to figure out.
If you have a servlet, I can see how one can have a session to save data in.

But if there is just a MDB how do you do it. Obviously, the session data should be available across servers.

Iam looking for a solution , with JMS.
Sorry to come in late on this. I have a question. Why use a stateless session bean ? Why not invoke POJO's directly from MDB.
What benefit is the stateless session bean giving you ?
It involves more than just login. There can be 5 or 8 messages , which need to maintain session data between them.

Looking to see how I can maintain session between session messages ( Besides the database approach )

Thanks

Mahesh
Keep in mind , I may not have a servlet. Just JMS and MDB.
I would prefer the database option, but it may not be an option for us.
Can you tell me more about Application Context.
