14 EAI JCAPS Questions And Answers

1⟩ How to route the data from JMS to different JCDs?

Just create a jcd using JMS otd. While creating JCD it will

ask for webservice. select JMS web service and when ever

any message comes to JMS it will automatically trigger that

JCD and you can perform certain operations in that JCD

3⟩ Explain Difference between DTD and XSD?

Both DTD (Document Type Definition) and XSD (Xml Schema Definition) intends to do the same thing: define the structure of an XML document.

DTD was introduced in 1999 along with the XML specification. It addresses the following:

1. Define elements, attributes and entities

2. The content model (what is between open tag and closing tag) for each element.

3. The possible attributes for an element

4. The content data type for elements and attributes

5. Entities that can be referenced by an XML

and so on.

As XML became more and more popular, in 2001 W3C standardized XSD to define the structure of an XML with more features:

1. XSD is follows XML syntax

2. Introduced over 40 datatypes

3. constraints on the data (of elements/ attributes)

4. precise no.of occurences of elements

and so on.

The biggest advantage of using an XSD over DTD is that you can specify all your validation rules in an XSD and the parser can check the same for you before the actual application that needs the data gets it.

6⟩ WHAT SUPPOSE IF YOU RECEIVE A FILE WHICH IS 10 GB IN JCAPS?

It will depend upon what type of file it is. If it is a text

file then the inbound JCD should be designed in such way that

it reads one line after the other and unmarshalls the data via

an OTD throgh a loop as it goes

If it is a XML file then the JCD should read through the XML

doc record by record and follow the process as mentioned

above.

7⟩ What is an Enterprise Manager?

The Sun SeeBeyond Enterprise Manager is a Web-based

interface that allows you to monitor and manage

your Sun Java Composite Application Platform Suite

applications. The Enterprise Manager requires

an eWay specific “plug-in” for each of your installed

eWays.

These plug-ins enable the Enterprise Manager to target

specific alert codes for each eWay type,

as well as to start and stop the inbound eWays.

The Sun Java Composite Application Platform Suite

Installation Guide describes how to

install the Sun SeeBeyond Enterprise Manager. The Sun

SeeBeyond eGate™ Integrator System Administration Guide

describes how to monitor servers, Services, logs, and

alerts using the Sun SeeBeyond Enterprise Manager

and the command-line client.
