Mobility Booth at Oracle WorldJavaOne 2011 at OracleWorld is next week (Oct. 2-6) at and around the Moscone Center in San Francisco.  You can get a pass to go to all of the sessions, which are $1595 to $2595 (the latter including Java University), but there are less expensive options as well if you are attending on your own nickel.

A Discover Pass for $75 gets you in the door with access to

  • Keynote sessions for JavaOne and Oracle OpenWorldT
  • "Scene and Be Heard" presentations,
  • Oracle Users Forums and SIG meetings
  • Exhibition Halls
  • Oracle and Java DEMOgrounds
  • Three (3) OpenWorld or JavaOne sessions
  • Bookstores
  • The OTN Lounge
  • The Mason Street Cafe

This is not a bad deal if you want to connect up with folks and smell what's in the breeze.

Another $75 gets you in Thursday with access to the cloud sessions.

Don't forget to register by September 30th!

please i need help in developing standalone application using EJB.
first i thank all who have been contributing in java.i am new to EJB.
my problem is :i tried to build remote application using Ejb ,
1. i build entity bean from datebase
2. i tried to build session bean from entity class for remote AP.
then error="EJB Remote Interface depends on JPA AEntity classes. JPA Entities are inaccessible if they are located in mode." i used netbean 7.2.1.

as i was making a research over a week ,i stormble over this solution
1 .that i should build class library
2. create entity bean in the class library
3.add the class library to the already created ejeModule
4.create persistence Unit
5.create session bean for entity class in ejbModule .
Great i used that to create my Remote application .

BUT:when i tried to build my ejeModule i keep on seen this malignant error
