Just to clarify some things about JDO 2.0... Though the JSR 243 was only recently submitted by Sun, the expert group had their first meeting last August and have been busy working on the spec since then. The plan is to release a public draft specification before JavaOne in June (this year). The work is over 95% completed.
Major features include * standardized object-relational mapping * a significant amount of functionality added to JDOQL, the JDO object-based query language * support for SQL queries as well * detach/attach functionality which is useful in Web applications to minimize concurrency issues Every few months it seems yet another company announces they are going to release a JDO implementation. Gavin King of Hibernate fame and the TopLink team at Oracle have stated they will support JDO 2.0. And the JDOcentral web site now has over 14,000 members. I have recently consulted for several companies that have made a decision to make JDO a standard technology to be used throughout their corporation, including a Fortune 100 company. Despite the lack of aggressive marketing by Sun, as we have seen with some other technologies (e.g. EJB), JDO is gaining momentum and adoption. But my sources tell me Sun is starting to see the light too... JDO 2.0 features will cause a significant increase in the JDO adoption rate. Patrick Linskey of SolarMetric is really sharp and a great speaker, so I encourage folks to attend.

At the end of the exit ramp, take a right (North) onto Davis Drive. Continue straight on Davis Drive for about 0.5 miles. Take a right on Cornwallis road. Go about 1/2 mile, you will cross over railroad tracks. At the IBM gate keep to the right. If the rightmost gate is down, press on the intercom button and tell the remote guard that you are attending the WebSphere User Group meeting, and give him your name. He will open the gate for you. Go through gate, follow the road around past the first Tivoli Building, looking for signs leading to Building 500 or "Software Group." Our IBM host is Greg Ackerman. Go through gate, follow the road around past the first Tivoli Building, looking for signs leading to Building 500 or "Software Group." It should be the third road on the left. It can be a little tricky, so please allow some extra time the first time. It can be a little tricky, so please allow some extra time the first time. You will see a visitors' parking lot. Turn in and park, and walk to the Building 500 lobby. Be careful not to go too far (the second Tivoli building is too far) or you will find yourself on a one-way exit ramp and have to drive back around. _______________________________________________ Juglist mailing list [EMAIL PROTECTED] http://trijug.org/mailman/listinfo/juglist_trijug.org _______________________________________________ Juglist mailing list [EMAIL PROTECTED] http://trijug.org/mailman/listinfo/juglist_trijug.org
