Many Many Congratulations

Applets are part of J2EE components . Java Spec it clearly states

J2EE Components

J2EE applications are made up of components. A J2EE component is a self-contained functional software unit that is assembled into a J2EE application with its related classes and files and that communicates with other components. The J2EE specification defines the following J2EE components:

* Application clients and applets are components that run on the client.
* Java Servlet and JavaServer PagesTrademarked (JSPTrademarked) technology components are web components that run on the server.
* Enterprise JavaBeansTrademarked (EJBTrademarked) components (enterprise beans) are business components that run on the server.

J2EE components are written in the Java programming language and are compiled in the same way as any program in the language. The difference between J2EE components and "standard" Java classes is that J2EE components are assembled into a J2EE application, are verified to be well formed and in compliance with the J2EE specification, and are deployed to production, where they are run and managed by the J2EE server.

Thanks a lot Uday for the reply

In EJB endpoint there are Session Bean which are stored in a Pool and invocation is done on any Bean which is free and available in the Pool so it is NOT multithreaded as for "n" number of request "n" number of Bean wll be used from the pool hence option <B>1</B> is true

For Servlet based endpoint , it is always One instance of servlet which handles "n" number of request so it is Multithreaded in nature hence option <B>4</B> is true

Many Many Congratulation .

A quick question Netbean IDE is it good for practice or you recommend any thing else on top of this

IdentifierBags
Represents various ways to identfy the same company for eg
If a company is identfy by Tax Number in a country and as My Company will have different Tax Number for different Countries so it will have different identification code. IdentifieBag will look something like this

<identifierBag>
<keyedReference tModelKey="India Tax Number" keyName="taxnumber" keyValue="222" />
<keyedReference tModelKey="UK Tax Number" keyName="taxnumber" keyValue="333" />

</identifierBag>


CategoryBag
Represent to what category my company belongs to ,If my happen that my company falls into many category , say I have hotel it can fall under category of Hotel or Resturant. So it will be represented like this

<categoryBag>
<keyedReference tModelKey="BusinessTypeClassification" keyName="resturant" keyValue="222" />
<keyedReference tModelKey="CityClassification" keyName="hotel" keyValue="333" />
</categoryBag>

<B>So the main difference between IdentifierBag and CategoryBag is that the namesapce identified by tModel in a categoryBag points to predefined category (BusinessTypeClassification/CityClassification)while in IdentifierBag this is not predefined

In real life categories are NAICS/ISO 3166 /UNSPSC

Servlet Context is one per application with in one JVM , but in distributed application Servlet Context is per JVM. That means if one Application is distributed among two JVM then there will be 2 Servlet Context in total, one per JVM

Yes that Right ..Correct Answer is application and pageContext are only implicit object where one can store attribute , which will be availabe from any part of Application
