Hi All,
My application makes use of JMX for obtaining notifications from other application.
Other applications are publishing notifications in form of MBeans. We have a JMX client which will be monitoring for new MBeans.
Here, my JMX client is unable to read MBeans in timely manner. Though, MBeans are already published in the server, my client reads them after 30 mins.
I have put log statements in the client code to understand what time we are reading messages. Even this seems to be not sufficient.

Can any body suggest how to fix this issue.

Thanks and Regards,

Hi All,
I was going through UML User Guide by Booch, Rumbaugh, and found concept of Forward Engineering in Use case diagrams. Forward engg. in use cases will lead to Test cases for the behaviour shown in that use case.
I was wondering any tool can be used to do Forward engg of use cases to Test scripts.

Is there any such tools available with this ability?

Hi All,
I am newbie to JSF, and i am working on client framework for JSF. I am stuck up with paging and sorting in my application.
I tried to search for paging and sorting in JSF, but all samples are using DataModel.
But, the framework i am using do not support DataModel.
Can anybody tell me how to implement paging and sorting without using DataModel ?

Thanks and Regards,

Hi,
I am facing similar situation. I have a hidden field for storing label, on which table needs to sorted.
Sorting is taken care in DB calls.
Based on the value of hidden field, i want to switch queries.

Hi Paul,
Thanks for reply
I am using J2EE RI. I had copied MySql from my friend's PC. I think i didnt copied any drivers for MySql. In that case, i will download driver.
I dont know (my friend too) username and password for MySql. He was starting database and running command Mysql -console from bin folder in MySql directory, and we get MySql prompt.
How to provide information about MySql to Entity Bean while deploying in the deploytool of J2EE RI?


Thanks and Regards,

Hi All,
I am using MySql as database for trying out entity bean examples.
Can anybody tell me how to use information about MySql in deploymenttool, so that my bean will make use of tables in MySql.

Thanks and Regards,

Congrats,
Can you share any study notes for 252 test


Thanks and Regards,

oops, sorry.
My question has to be like this
Implementation of ejbCreate methods in session beans do not declare CreateException in bean code.
Implementation of ejbCreate methods in entithy beans do declare CreateException in bean code.
This i am not sure, i saw a piece of code in HFEJB, when i was reading chapter 5 - Entity bean synchronization.
Is it really entity beans can declare exceptions(other than custom exceptions) when implementing create / finder methods in bean class.


Thanks and Regards

That clears my confusion.

Thanks and Regards

Hi All,
Thanks for the responses.
Awishek caught partially what i meant to say.
When clients invoke finder methods, a bean instance in the pool will query database for the existence of the primary key in the database. If found, then container will find (or makes) EJBObject and send its stub to client. This is how flow for finder method goes right.
Now, at the point

If found, then container will find (or makes) EJBObject and send its stub to client.

I am confused. How container finds an EJBOject which is related to the primary key?
If a EJBObject is alive, then bean instance acting as entity bean for that primary key must be active and in method ready state.
All i want to know is how the container service will find one?
Please correct and excuse me if i am wrong.


Thanks and Regards
