Hi

Class diagram is the one which talks purely about business.

Your component diagram should talk about technologies and
patterns used.

The idea is that the business and technology should not be
mixed up.

I worked in Singapore for 4 and half years.
No doubt 3000 is reasonably a very good salary for a person
with 1.5 years of experience.

Hi Guys,

It's not just DB pool more than that,
Like Providing JTA Transactions, Security, Object Pooling and much much
more.

Refer to any good books for further clarification.
Enterprise Java Beans by Oreily might be a good source.
My Architect wants to seperate the business methods from the container callback methods.

I was recommending to provide wrapper methods in Session Beans for the
Business Methods.
A environment is said to be managed when you make use of Application Server/Container Services.

For example If you use Connection provided by the container by looking
up JNDI datasource you are in a managed environment,

Where as if we use JDBC connection directly then it is said to be
Non-Managed Environment.

Hope it helps


It's not odd design. One reason could be that ServiceImpl code already exists



ServiceImpl does not exist, we are creating everything from the scratch.


I am assuming your services/business methods are exposed thru BusinessDelegate to outside world.



There is no Business Delegate involved.
Hi Folks,

I would appreciate your suggestions and comments on the following design approach.

In our project we have decided to use Stateless Session EJBs with Containter Managed Transaction.

In our existing design the Bean Class extends a normal java class which contains all the business methods.

for example


My architect has been recommending this approach to sepearte business concerns from the actual ejb class. But i have been recommending not to adopt this design as we may loose some of the features provided by
the EJB Container like SessionContext handling etc.

It would be great, if all of you could share your thoughts.
Your suggestions would really help us to make a decision.

Hi,

This might be a dumb question.
But it would be great if you could share your thoughts.

Is it possible to achieve two-phase commit using pure JDBC ?

Assuming that you have two web servers supporting two different
database, In this case how can i achieve two-phase commit
across the webservers.

I was just curious about this scenario...

Actually speaking hibernate query language supports > < >= <=.
I was able to solve this problem by using to_date(to_char functions
in my hibernate query language
