Day two of TSSJS was for me mainly a Spring and Oracle experience.

Floyd started the day by mentioning that the approach of inviting the same speakers who contribute to J2EE is "by Design". After a few more polls: 65% is not using or plan to use AOP, only 20% can introduce freely open-source API's, other have a committee to review this, it was time to Spring. (al wie da nie springt, al wie da nie springt, is ...) Rod Johnson dominates the symposium with 4 sessions!!

During lunch Ted Farrell from Oracle gave a fun keynote on "Does J2EE matter ?" with some nice demo's of EJB3 (an early draft implementation can already be downloaded from Oracle) and JSF. I wonder when Oracle will also make the switch to Eclipse ?

When JavaPolis 2005 takes place (by the way that's December 12th till 16th) migrating to EJB3 will be The Hot Topic! Hopefully by then every application server will support it... This is why I attended Mike's Keith talk to see if he could do a similar talk "How to migrate to EJB3" at JavaPolis, which he will Maybe we should again invite Gavin King for a talk on "Migrating Hibernate3 to EJB3", I'll check out his talk today and ask him if it makes sense and if he's interested.

Frank Cohen was sitting next to me during lunch, I knew him of the BEA Technical Director emails and told me he spends a lot of time with Java Communities around the Bay area. We exchanged cards so we could keep in touch on speakers, topics and other related Java stuff that might be of interested for both SIGs.

During that keynote, Floyd pointed out to me that they're using a "monitor" to count the number of minutes the speaker still has available. The application starts blinking when the time is over and I was just waiting to see if it would explode if the speaker exceeds his limit Great idea for JavaPolis. Floyd told me that during next years Symposium, he'll release a DVD of all the talks on it. This is great, the inspiration works both ways, now he stills needs to reduce his entry fee to 300 dollars

Peter Zadrozny said hello while I was in the process of gluing MyFaces with Spring, he confirmed that Oracle Corp. will again support our conference initiative, Great !! That reminds me, I need to get hold of the MacroMedia guys here in the US...

The last session I followed was a BOF from John Rizzo on JavaBlackBelt. I really like the initiative and idea but I was a bit disappointed that during the presentation Null Pointer Exceptions were still thrown Murphy was definitely present because he also turned of the lights for a few seconds.

So today I want to see Dain Sundstrom from Geronimo, Cameron Purdy, Gavin King and Jason Hunter in action and then it's back to Belgium...

Just spoke with Dain Sundstrom and he'll present Geronimo at this years JavaPolis. This will be perfect timing for Geronimo as a final first certified version will be ready around that time-frame !

Hi Stephan - I'm afraid your wish that every application server would support EJB3 by December 2005 is a little unrealistic Consider that BEA and IBM don't even have production servers for J2EE 1.4 yet... So how long is it gonna take until final J2EE 1.5 versions of WebLogic and WebSphere hit the market? I would guess at least till 2007, given that the J2EE 1.5 umbrella spec won't become final before 2006. And how long will it take until those server versions hit the mainstream? Oh well... In any case, EJB3 is arguably distant future for WebLogic and WebSphere users. Cheers, Juergen

Juergen, you do know that Oracle and JBoss already have a pre-public draft EJB3 spec. implementation which (I think) will push BEA to have one as well ASAP. I don't know what Geronimo will have by then, maybe Dain can tell, and personally I'm not really interested in WebSphere

Check out this fun thread on Oracle and Eclipse.

Hi Stephan - I'm aware of the EJB3 previews by JBoss and Oracle, of course. However, this doesn't change the fact that the two application servers with the largest enterprise market share don't even have production J2EE 1.4 servers yet. We're lucky if get WebLogic 9.0 final and WebSphere 6.0 final in Q2/2005, and that's just EJB 2.1! So realistically speaking, even if BEA and IBM would hurry (which is at least far from obvious), we won't see production EJB3 support in WebLogic and WebSphere before late 2006. (And then, how long is it gonna take until the average WebLogic or WebSphere user upgrades?) And Geronimo, well... they first need to get a J2EE 1.4 version out too, and do not show particularly fast progression in general. Also, where do they take an Apache-licensed EJB3 persistence engine from? Finally, keep in mind that EJB3 is somewhat tied to the timeframe of the J2EE 1.5 umbrella spec, which is unlikely to become final before early 2006. Cheers, Juergen

Stephan, regarding Oracle and Eclipse, you might want to check out this press release as well...

This is great news, I've posted it also on the BeJUG wiki and the most important part below:

As the leader of the project, Oracle will help build an open source EJB 3.0 Object-Relational Mapping (ORM) tool under the Eclipse Public License that focuses on design-time tooling and supports deployment to any J2EE-compatible application server. The new tool will build on Oracle's expertise in persistence with Oracle® TopLink, a Java object-to-relational tool and deployment platform that provides advanced ORM capabilities suitable for mission critical enterprise applications."

"will help", does this mean other companies will join ?

What I like are the words "supports deployment to any J2EE-compatible application Server"

Does this mean that Mike Keith will be able to give us some more details during our BeJUGs Persistency Workshop in June !!?

Well Eclipse is a community effort. It's natural for people in a community to help each other, isn't it ?

bq What I like are the words "supports deployment to any J2EE-compatible application Server"

I think that's precisely where other companies contributing will play a role: create the specific feature support for their EJB3 implementation. But then also, ejb3 is more complete as a standard than the previous versions, so hopefully "standard-only" beans, with no extensions, will be useable.

bq Does this mean that Mike Keith will be able to give us some more details during our BeJUGs Persistency Workshop in June !!?

Surely.
