hi all 2.A shipping company is building an enterprise system to track the location of packages.One part of the tracking sys- tem is a network of wireless inventory devices.The devices can only be accessed using a custom,synchronous TCP/IP protocol.How should you encapsulate interaction with the wireless inventory system?
A.with a Java class that uses a JMS to interact with the inventory system B.with a distributed CORBA object that uses IIOP to interact directly with the inventory system C.with an EJB Tstateful session bean that uses Java sockets to interact with the inventory system D.with an EJB entity bean that uses container-managed persistence to encapsulate the inventory system My doubt Can I open a socket connection from a session bean? After all Iam using few I/O operations which is not allowed according to the specification and most of the appservers do not allow I/O operations. Am I missing some thing?? thanks in avance ramesh =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".
