[Poonam Agarwal]

hello ranchers,

refering to Enthuware mock , please consider the code below-

Which of the following files possibly contains a web application?

A. webmail.ear
B. webmail.war
C. webmail.jar
D. webmail.xml
E. webmail.xar

given answers A, C.
I have refered HFSJ but i wonder if there is something written about the .ear(Enterprise Archieve) files. Do we expect such questions on exam.

Please verify

EAR (Enterprise ARchive) files can contain web components (WAR), EJBs (EJB-JAR), any other libraries (JAR) and application.xml (of course). It's a standard way of packaging enterprise applications for deployment.

shouldnt the answer be

A) webmail.ear and B) webmail.war

as jar file usually contains all the libs..

[Milton Ochoa]

I agree with swati

To answer the poster's question, I'd say that you don't need to know about EAR. Section 2 of the exam objectives is :

Section 2: The Structure and Deployment of Web Applications
* Construct the file and directory structure of a Web Application that may contain (a) static content, (b) JSP pages, (c) servlet classes, (d) the deployment descriptor, (e) tag libraries, (d) JAR files, and (e) Java class files; and describe how to protect resource files from HTTP access.
* Describe the purpose and semantics of the deployment descriptor.
* Construct the correct structure of the deployment descriptor.
* Explain the purpose of a WAR file and describe the contents of a WAR file, how one may be constructed.

I don't think you are supposed to know about EAR. (although it won't hurt to know about it ;) )

Even I think that only ear and war can contain a complete web app. A jar is usually used to carry 3rd party library although i am not sure if it too can contain a complete web app.

Can someone highlight on this point a bit more ??

The correct options as shown by the simulator are indeed A and B.
Reference to ear is for the sake of completion. No details of ear are asked in any question.

HTH,
Paul.
