Thanks Sudipto, for your detailed suggestion. This will be of much help. Thanks

Thanks Sudipto, Actually I have to attend a interview soon. What should a Java Developer know atleast on Weblogic 10.3 ?

Hi,
I want to learn Weblogic 10.3 from a developer perspective and to some extent about administration. I have the book "Weblogic 8.1 Unleashed". Can I use it to understand the basics ? Where does it mainly differ from 10.3 Please suggest.

Thanks.

Thanks Tim and Bill for your valuable inputs. I have a question for Bill.
Please elaborate your answer. Since I am new to this, please mention particularly which are the technologies(Jaxb, uddi etc) I need to know at the least. Please also mention the book you would like me to follow.
Hope you understand me.

Thanks,
Subhadeep

hi,
I am struggling to understand the search APIs. Few of them that I know are Lucene and Hibernate Search. Lucene is a text search api(not database) and with hibernate i can search the database.Am I correct ? Please advice me on which search api is good and in which way. What are the other good search APIs in the market. I am a java developer and looking for a search api to search the database.

Hi,
I am really sorry for this unavoidable delay. Please don't think otherwise.
I have a small doubt.

if(result != null) // Case another thread altered it
System.out.println("Previous value: " + result);
}

As I understand, this is to understand when element has been added.

and,

But the above is about 250% faster

This is because the above code will call putifAbsent() less frequently.

Is my understanding correct ?

Thanks,

hi,
I need an ThreadSafe collection.I am unable to understand the difference between unmodifiablexxx() and Singletonxx() of Collections class ,both seem to return immutable objects. So are they threadSafe ?

If I can use immutable object I donot want to use synchronized Collections (synchronizedxxx())
Please Advice.

hi,
Thanks for you response.My existing application gets the data from session and if I store the data in application
context I shall have to go through the whole application and change.I do not want to do that.

Is it possible to override weblogic 10.3's HttpSession implementation and override getAttribute() to do my work.

Is there a different way?

Thanks,

Hi,
I have a situation where on each login huge data is fetched from database and stored into the users session. I do not want the database query to run every time and want to load the data at application startup in applicaion scope thus making session contain less data and also decreasing the database query time. My whole application is getting the data currently from session and I donot want to change it. Is there a way to do this ?

Thanks "Seetharaman". I understand that its difficult to answer these sort of questions and I am not expecting a direct answer.We have people here having a lot of experience and knowledge and if they guide us a bit we can take better decisions.
I have these questions.
1) Can any other language integrated with java be of some help.
OR
2) Do you think that if correctly implemented a satisfactory answer can be found with only java.

Thanks,
Subhadeep.

hi,
I have a doubt whether its better to use pagination logic in jsp and store the data in session or store the same on the persistence layer such as hibernate.

As I understand.
If you are storing in Jsp ,memory use will be high and this is more of model work then view work(storing the data).
If I store it in the persistence layer, the request has to go all the way to get the data.

The scenario is :-
1) User might access any of the pages abruptly and there are lots of pages(100).
2) How does the solution get effected in case of a clustered environment.

Thanks,
Subhadeep

Sorry for answering late. Thank you all for helping me out with the answers,
Just wanted to know is there any book which would give me a better insight into understanding concepts like this. I have read books like scjp1.6 Kathy Sierra, scjp 1.4 khalid Mughal, Complete Reference, Core Java(Vol 1) Sun Press and Effective Java.

Thank you.
