JOE, Thanks for your reply, I guess class diagram is tightly related to sequence diagram, then for sequence diagram, do we need to should those methods like jndi lookup and home.create()?

Also wondering if Rose is right tool to use, since if you want to draw EJB class diagram, after following its wizard, it automatically generates all home/remote interface, bean class, and primary key class optionally.

Thanks

Hi,
I am not sure in the class diagram, if we are going to present a EJB, how should we do it? In RationalRose, it will gernerate all remoteinterface, homeinterface and Bean class itself, just want to make sure if this is right way to go.

Thanks

I can say it confirmly why in EJB1.1 BMP is faster


oops, correction
I can NOT say it confirmly why in EJB1.1 BMP is faster
I think there is an arguement that in EJB1.1, BMP performs better than CMP, so whenever performance is essentail, chose BMP, that why a,c are correct, and since BMP can handle complex data type, that is why choosing d.
I can say it confirmly why in EJB1.1 BMP is faster, but I think whoever give this mock question must think in this way.
any suggestion?


1. Which of the following is not an optional step in establishing an SSL handshake?
a. Server side certificate validation by the client
b. client side certificate validation by the server
c. Generation of session keys for encryption and decryption
d. Selection of a suitable Cipher suite for encryption by the server and the client
The correct answer is b ,but I don't know why?I think all steps are needed



Since question is asking about not an optional step. so answer should be a, c, d IMO, since SSL has two authentication modes, mutual and server, so client side certificate authentication should be optional, please refer to "Sun certified enterprise achitect for j2ee study guide" chapter 10.
The default value of attribute "use" of element "xsd:attribute" is "optional", so c is the correct answer.

There is a IBM mock question about "XML rendering". but I searched Skonnard book, Professional XML, even Google, just hard to get it. Can somebody explain to me what exactly is this concept about?
Thanks

"/descentant::sku[not(.=preceding::sku)]".
I believe "/descentant::sku" will return back a node-set of sku, the conditiion [not(.=preceding::sku)] will be applied to each node in the set, then "." means each sku node being tested.
Any comments?
For security, answer is not suitable, here is the quote from JMS1.02 Spec section 2.7
"JMS does not provide features for controlling or configuring message integrity or message privacy. It is expected that many JMS providers will provide such features. It is also expected that configuration of these services will be handled by provider-specific administration tools. Clients will get the proper security configuration as part of the administered objects they use."
For transaction, I am not sure, since JMS has a concept of "transacted session" which "groups a set of produced messages and a set of consumed messages into an atomic unit of work."
but in Spec section 1.4.4
"A JMS client may use JTA to delimit distributed transactions; however, this is a function of the transaction environment the client is running in. It is not a feature of JMS per se."
I wouldn't say HTML is a Protocol, it is a tag formatted message, you can use any protocol to transmit it, like you can see HTML in broswer by using HTTP, you can see it in your outlook email box by using SMTP.
Maybe all of them are correct,
MDB could act as message consumer, and others could be producers.
Hi, I wonder for WLS certification, do I have to prepare for Web application Listener and Web application filter. Since they are so new, only available in Servlet Spec2.3.

Thanks
