Re: Messaging Bean

[Kalra, Ashwani]

you will not gain much on using session beans. Can you give more details on what you will be doing in the java classes? Pooling and transaction is provided for MDBs also. if you are doing lot of CRUD operations, than use of Entity EJBs should improve scalability.     /Regds Ashwani    -----Original Message----- From: Sachin Tandon [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 16, 2003 9:59 PM To: [EMAIL PROTECTED] Subject: Messaging Bean Hi   We are using Messaging Beans on our project. The message bean in turn will be calling different java classes for performing some actions. The java classes will be having business logic and will access the DB. We will process billions of records.   I wanted to decide on using EJBs against normal java classes in this scenario.   1)       Billions of rows of data to be processed 2)       Lots of calculation involved in processing data 3)       Weblogic clustering - need to load balance requests received by MDB across instances.   Any thoughts? What do we loose when we use normal java classes in this scenario as against using session beans   Thanks     =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".
