EJB In Action page 78.
Business method names must not start with "ejb".


Result:

17:47:17,953 INFO [STDOUT] Start: PlaceBidBean.initializeBean()
17:47:17,953 INFO [STDOUT] Inside init: PostConstruct, PostActivate
17:47:17,953 INFO [STDOUT] End: PlaceBidBean.initializeBean()

PlaceBidRemote interface has a business method ejbAddBid() and it worked perfectly?
Is something wrong with the book or am i going wrong, i see lot of such issues.

I tried it for method in Stateless session bean. There is no problem if method name starts with ejb like "ejbSomeMethod()". It works perfectly.

the ejb speci. says it must not start with ejb, to avoid naming conflicts javax.ejb.Enterprise Beans method's. It does not prohibit to do so. Again it's vendor implentation how to behave.

So can i conclude that even if Specs says "MUST NOT" its application vendor specific.

Your goal is to pass the exam. Stick to the spec. I don't see a point in proving that some vendor implementation allows some things which are prohibited by spec.
BTW: Relying on such things in real commercial projects is not the smartest thing to do.

Deepak,

Sorry for the delay in responding...I just came back from vacation...

The implementation you are using appears to be in violation of the spec.

Best regards,
Reza

One more....

Hi Rahman,
Yes it cleary violates the specification. The code was deployed with jboss-4.2.3.GA application server.

Looks like one must not use jboss-4.2.3.GA.
Please suggest a better application server which is completely compliant with ejb 3.0 specification

I think we need to put these similar cases in SCBCD FAQ, if its not there already.

Deepak,

The reality is that no application server is *100%* spec compliant. That being said, I don't think this is really a critical issue, as long as your code is spec compliant. All Java EE 5 certified application servers must pass the Sun compatibility test kit, but the set of tests in the test kit is not necessarily perfect (I think that would be an almost impossible job).

I would say try JBoss 5, which is Java EE 5 certified. GlassFish, Geronimo, WebLogic and WebSphere are good choices too. In particular, I know that Geronimo and WebLogic tries hard to be spec compliant, even beyond the certification test kit.

Hope this helps,
Reza
