Hello,

I am well through the HF-EJB book and, along with practice, am getting to be quite comfortable with EJB in general.

The problem area seems to be the attributes we are required to remember for the exam. Part of the problem is because of the fact that I don't write the XML myself (the RI generates it as against the Bean interface method names, exceptions, etc. which directly indicate what I have done wrong at complie time, etc. )

On the face of it, the tags make sense and, in fact, appear to be simple. When I get down to the exercises, I realize how confused I am.

What is the approach used by the experienced folks?

Regards,
Saket

My suggestion will be to devide dd in 6 roles defined in specs. 3.1.

Remember when you are writing the beans and deploying them you are juggling hats for "Enterprise Bean Provider", "Application Assembler", "Deployer", and up to some extent "System Administrator".

When you try to take DD as a whole entity, you are bound to get confused.

Make sure you define your role while looking at DD.

That way you know that when you are looking at DD as "Enterprise Bean Provider" there are very few tag you are concernted about. Secondly the tag name itself will start making sense.

HOpe this helps

I was having the similar confusion.

I made 6 seperate DD files by refering to http://www.valoxo.ch/jr/DeploymentDescriptor.pdf

I mainited the similar coding convention in my word files.
The 6 files are -
1. DD_EJBQL.doc
2 DD_Environment.doc
3 DD_Relationship.doc
4 DD_Security.doc
5 DD_Transaction.doc
6 DD_General.doc

This helped me a lot to remember the tags well.

If you want , I can send you the files. If I copy-paste the contents here the formating and colouringis lost. Not sure how to attach files on this board.

Hope it helps!

Thanks, Gemini.

I will delve into the PDF for now, and if required get back to you for the separate doc files.
