You can use Views for this purpose. Some app servers like weblogic have explicit support for this.

Portability is indeed a vague term.In a real scenario,how many time,we change the application servers and databases?So why should one consider the portability aspect,if they had really made their mind on the infrastructure(h/w and s/w)?

hi prashant,
First of all everything is reinvented by sun..like entity beans...its concept is nothing but like views of a rdbms..right. ofcourse they have a lot more advantages than views..but still the basic is duplication of data and now EJB-QL for querying the objects..another duplicate work. why not just use session beans and use sql and rdbms avoid entity beans completely. Lets wait and see what SUN says about this.

Hi Kathy/Bert
With a lot of hype and enthu over JDO do you think EJB technology would sustain for a long time.Is it advisable to buy the book "head First EJB" and study for SCBCD. What is your opinion about EJB's future against JDO.
