Dear All,

Can anyone suggest all the spec which is defined in WebServices
are stable.

For eg:
When we compare EJB 1.0 (not at all stabilised one)
EJB 1.1(Yes it started to take a shape)
EJB 2.0 (Many application went into production
this time)

Thanks and Reg

Is it possible?
I want to extend Logger Class like MyLogger

and add new Level like Trace

How to make the MyLogger.getLogger
to return MyLogger instance

MyLogger must extend Logger

Thanks in advance
Thanks Hari

Planning to take in 1 month time..

Let me see how i can proceed with my preparation
Thanks Dhiren

The links are very much useful.

Do you have any sites for sample questions where we can work out like
SCJP.

I know basic of DOM ,DTD ,SAX ...

How long it will take time for prep for this exam
Hi Luigi
This is quite intersting stuff..
1. If we have foreign key fields in the DB we can directly
map it with CMP field of EJB (If u have all the FK
fields through some DAO of your app we can directly map to it)
2. CMR :Websphere 5.1 allows only to map FK constraints
rather than FK fields.
It mandates our application to maintain the integrity CMR
relation
In the above cases 1 and 2 we can
atmost have 1 not the 2 cases

I like to thank all the members in the
group for active participation.
1. My special thanks for K&B for wonderful book
2. I read the spec once
3. also read EJB by Richard Monson-Haefal
The difference i saw in this exam there is considerable
amount of drag and drop
The difficulty i faced whenever i want to review my drag and drop
questions all the values are getting reset
I have answer again that question
In 1 drag and drop system got hanged and i was not
at all able to answer that question
So 1 question left unanswered
