Hi Kiran,

Yes thats what i tried. I put the weblogic context factory in the properties and put wlclient.jar in classpath of glassfish (I tried putting it in lib folder of my WEB-INF too.) . It looks like weblogic client jar is creating some conflicts with glassfish. My application failed to deploy.
If i remove wlclient.jar, Application deploys fine without error.

Thanks,

Hi,

I have a JSF web application which is deployed on Glassfish server and i have EJB 3 components deployed on weblogic 10 server. How can i call those EJBs from the JSF managed beans.
I tried to use InitialContext by setting context factory to weblogic context factory and putting wlclient.jar in the classpath of JSF web app. It doesnt work. JSF application is failed to deploy.

Is there something i am missing.

Any quick help is really really appreciable.

Thanks,

Hi Naresh,

What my point was, rather than storing all the product information , like id, title, description, images , reviews, comments, quantity, price at EJB level, we just store product id and quantity in the Session bean. Rest of the information we can store in Httpsession at the presentaion layer. Just my two cents. Wouldn't it be costly transaction to fetch all the data from SFSB every time , user clicks on the cart to view it.
What are the other options of caching the data at presentation layer?

Thanks,

How about maintaining cart in the http session as a POJO for display purpose along with the SFSB. Whenever cart is modified (updated for quantity, or deleted or inserted) then make update to SFSB and sync up the Http session also.

Hi,

This is a general design level question.

1.) I am using EJB3+JPA and JSF for presentation. What is the best pattern to use backend objects in presentation layer.
I am planning to use Stateless session bean as a facade to entities and use detached entities from managed bean. Is this acceptable approach? . Is there any value addition for using DAO or DTO pattern here.

2.) Should i put detached entities in HttpSession or i should create statefull session bean and put its handle to http session?

3.) Does it make sense to maintain cache of entities at presentation layer for performance for e.g Product catalogue.

4.) What is the naming convention for the managed bean , should it be called Controller? For e.g UserController or Managed Bean, like UserManagedBean.

Thanks for helping me out.

Hi Gregg,

I am just trying to understand the comparison of performance , failover and load balancing aspects of weblogic and tomcat. This is not project specific question. Just trying to figure out, is there anyone out there, who uses tomcat in production environment, with 40 to 50 thousands of users with multiple hundreds concurrent requests served.

Thanks,
Brijesh

Hi Stefan,

Thanks for your reply. Well I have a option to use EJB or Spring. So after considering performance, load balancing and fail over criteria for weblogic as well as tomat, I can start designing my solution. My existing app is using weblogic (version 6 without EJB) and was written 10 years back , so we want to decommission it and rewrite it. My company may not consider JBoss, because, that will be new skill set required for the system group. Tomcat is fine, Because They already manage tomcat with different other internal applications.

My Application is simple transactional (DB only) web based application. I may not need full J2EE stack for this app.

Any further insight will be helpful.

Thanks

Hello Fellow architects.

I am in dilemma whether i should use weblogic, or tomcat.
Application has around 50000 Users and expecting 300 to 400 concurrent users doing the transactions.

I know weblogic license is costly and would like to save that cost, but not by compromising the user security, scalability and performance.
Can tomcat be able to handle this many user requests. Can we put trust on its cluster support for failover?

Any advise is greatly appreciated.

Thanks,

Hi,

I have passed SCEA5 part 1 exam. I am not getting clear information anywhere, as how to proceed with step 2 exam. Where to order the exam and how would i receive the assignment.
Can please anyone help me?

Hi Everyone,

Today i took SCEA 5 part 1 exam. I cleared it on the edge. Questions were really complex and quite twisted. I had read couple of SCEA books and prepared around 500 mock questions. But none of this helped. Not a single question was repeated, what i had prepared. When i started, i was sure, i would definitely not be able to clear it. But used best possible answer approach, so cleared it with 58%.

Thanks for everyone's help.
