JCAPS - beginners' Guide

JCAPS : The first thing to know about this is ..

• JCAPS - Java Composite Application Platform Suite

The other Things we should know are:

• Whose product is this?
• Ans: This is a Product from Sun Microsystems Inc which is now acquired by Oracle. The Journey of JCAPS started with ICAN. ICAN is a product of Seebeyond and after Sun's acquisition of SeeBeyond, ICAN is transformed into JCAPS.
• What it does?
• Ans: JCAPS is an EAI tool which handles information exchange between two heterogeneous or homogenous systems. It also facilitates transformations and business rules to be applied on the data before the data is exchanged. Besides mere data exchange, JCAPS also provides various other facilities which we will discuss in detail later.
• What are the limitations?
• Ans: The very basic limitation is that its components are heavy. If the task is simple and straight forward and can be accomplished using plain java and xml, then it will be less efficient if we use JCAPS.
• What is the latest version in use?
• Ans:JCAPS 6
• Finally, How we should Use?
• Ans:This is a very small question that has an un-ending answer. So, lets start with a scenario and expand our understanding further.
• What are the prerequisite skills should the developer have to start working?
• Ans: JCAPS is a SOA based tool and JAVA is the language it uses for programming. So, basic understanding of SOA and Java are necessary. JCAPS is to make life easier with integration (infact any composite application suite) with use of SOA.

If these questions and their anwsers are clear to you, you can work on JCAPS comfortably. So, we would be discussing scenarios one after the other.

Basic components of JCAPS:

1. eGate Integrator
2. EBAM
3. E Insight
4. to be continued..

Aqua Logic - BPM

Aqua Logic Business Process Management tool is a BPM tool and now it is aquired by Oracle. Before we start with design of business process, we should understand the business logic that needs to be solved by our process. We also should identify the People and Data that the process requires.

The steps we normally follow will be like below:

Identify the Process Elements:

1. Roles involved in the process
2. The Begin and End activities
3. A Global Creation Activity
4. Interactive Activities
5. Automatic Activities
6. Finally the Transitions

Then we proceed with designing the process. A pefectly understood process flow will guide you to design a perfect solution.

Quick Reference to Business Process Management

A business process is "a collection of related, structured activities that produce a service or product that meet the needs of a client".

Business process management activities can be grouped into five categories:

Design:

Process Design encompasses both the identification of existing processes and the design of "to-be" processes. Areas of focus include representation of the process flow, the actors within it, alerts & notifications, escalations, Standard Operating Procedures, Service Level Agreements, and task hand-over mechanisms.

Modeling:

Modeling takes the theoretical design and introduces combinations of variables (e.g., changes in rent or materials costs, which determine how the process might operate under different circumstances).

Execution:

One of the ways to automate processes is to develop or purchase an application that executes the required steps of the process; however, in practice, these applications rarely execute all the steps of the process accurately or completely. Another approach is to use a combination of software and human intervention; however this approach is more complex, making the documentation process difficult.

Monitoring:

Monitoring encompasses the tracking of individual processes, so that information on their state can be easily seen, and statistics on the performance of one or more processes can be provided. An example of the tracking is being able to determine the state of a customer order (e.g. ordered arrived, awaiting delivery, invoice paid) so that problems in its operation can be identified and corrected.

Optimization:

Process optimization includes retrieving process performance information from modeling or monitoring phase; identifying the potential or actual bottlenecks and the potential opportunities for cost savings or other improvements; and then, applying those enhancements in the design of the process. Overall, this creates greater business value.

Difference between Constructors and Methods

Difference b/w Constructors and Methods

Question

What does a constructor meant for? And how it differs from methods?

Answer

Constructor is to create instance of a class, you may call it as "creating an object". While methods are just to execute a piece of java code. Constructors and methods differ in three aspects of the signature: modifiers, return type, and name.

--> Constructors dont have return types, not even void.

--> Like methods, Constructors can have any of the access modifiers: public, protected, private or none. But unlike methods, they cannot be abstract, final, native, static or synchronized.

--> Name of the constructor is always same as that of the Class to which it belongs to, while methods normally have names other than their class name.

Difference Between Abstract Class and Interface

Difference between abstract Class and Interface

a) All the methods declared inside an interface are abstract whereas abstract class must have at least one abstract method and others may be concrete or abstract.

b) In abstract class, key word abstract must be used for the methods
Whereas interface we need not use that keyword for the methods.

c) Abstract class must have subclasses whereas interface can't have subclasses.

d) By default what ever variables we decalre in interface are public static final,where as in abstract class they can be default and instance variables also

Question

What does the keyword 'static' mean?

Answer

The static keyword denotes that a member variable, or method, can be accessed without requiring an instantiation of the class to which it belongs.

Welcome !!!!!

Hi

This blog is for those who are looking for quick learning on various technology related topics. Since I work on Java, most of the posts would contain information on Java...
I hope this would be useful .....Wish you good luck..
