The java.util.concurrent package contains a set of synchronized Queue interfaces and classes.

When we are dealing with stateful session beans we need to store the client conversation of the bean so that it can be available in client’s next request. But when we talk about server it has limited resources. If the conversation of the bean is large then the server can run out of resource.

There are four scope which an object can have in a JSP page:- Page Scope Objects with page scope are accessible only within the page. Data only is valid for the current response. Once the response is sent back to the browser then data is no more valid. Even if request is passed from one page to other the data is lost. Request Scope Objects with request scope are accessible from pages processing the same request in which they were created. Once the container has processed the req

A transaction is proper if it fulfils ACID properties. These four properties are as below:- Atomicity: - This rule states if one part of the transaction fails then the entire transaction should fail. Consistency: - This rule states that only valid data should be written to database. Any invalid data should roll back the whole transaction. If the transaction executes successfully then it should take database from one state which is consistent to other state which is also consistent.
