Also given the fact that entity beans can be shared by multiple clients while session beans cannot.
Lets say I have a stateful session bean and the create method being ejbobject create(int accId) A person logs in with accountId 1 (A stateful session bean instance created - SF1) At the same time his wife logs in accessing this account(Another stateful session bean created - SF2) now SF1.isIdentical(SF2) will return false. while if is an entity bean they will share the same primary key and hence the same entity bean instance. I was wondering if this can cause any issues!!! Any comments?? - Rajeev Dave -----Original Message----- From: Evan Ireland [mailto:[EMAIL PROTECTED]] Sent: Friday, January 25, 2002 4:39 AM To: [EMAIL PROTECTED] Subject: Re: SFSB Question Use an entity bean with BMP. Take all the data you wanted to pass as a parameter, make a primary key class containing that data. ejbLoad/ejbStore can be empty, as you don't need any persistent fields. In your business methods where you want to access the data that was passed to ejbCreate, call entityContext.getPrimaryKey() to get the values.
