&gt;&gt;* When developers are designing J2ee web app, EJB is always necessary? <br />
<br />
No. it depends on your application. you need EJB only if the application needs it. if you can develop more scalable application without using EJB then you might prefer not to use EJB's.<br />

Hi Experts,<br />
<br />
while I was reading some of the articles about J2ee and EJB, I had these questions.<br />
<br />
* Is web application that was developed in Struts frame always J2ee?<br />
<br />
* When developers are designing J2ee web app, EJB is always necessary? <br />
<br />
* In order to separate functionality of application components among session beans, entity beans and MDBs, what are things that they consider?<br />
<br />
thanks in advance,

J2ee designing questions in terms of EJB

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
