XML to JSON converter in Siebel

Often we come across requirement for Siebel to integrate with external applications. Siebel provides various ways to integrate through EAI (Enterprise Application Integration) like EIM, Prebuilt connectors, various queues like MSMQ, JMS, WebSphere MQ. Also Web service based integration using SOAP. Siebel also supports RESTful based integration using Fusion Middleware.

One important feature of Siebel EAI is EAI Java Business Service which can be used to invoke external Java class to perform various operations.
In this article we will see how we can use various EAI Business services to communicate with JSON API of external application. We will have an XML input processed and resulted into a JSON output in Siebel.

Bug / Defect Priority vs Severity Matrix

In Software Testing, deciding how important the defect is and how soon the defect should be fixed is as important as finding a defect! This depends on how you actually place the defect into Priority-Severity matrix.

I have come across a lot many test engineers, who get confused between priority and severity of a defect. Definition is important but understanding is even more important.

Definitly customer (guidelines) plays a major role in the decision but I’d like to convey in terms of the general scenario. I’d like to add some easy words to clarify the confusion (probably forever).

Defect Priority: Priority is something that is defined by business rules. It defines how important the defect is and how early it should be fixed.

Defect Severity: Severity is defined by the extent of damage done by the defect. It defines how badly the defect affects the functionality of the software product.

Again you’re fed with another definition? No!! Let’s take some examples…

They say a picture is better than a thousand words:

defect-priority-severity-matrix

High Priority and Low Severity:

Company logo is half cut on the home page of its website. This is high priority defect because displaying an incomplete company logo would put bad impression on business as this would defame the company or website. So, this defect should be fixed as soon as possible.

As far as severity is concerned, this defect has got low severity because it is not impacting any functionality of the website.

High Priority and High Severity:

Login button is not clickable on the login page of a web application. This is a high priority defect because this is stopping users from using the site. So, this should be fixed at once.

At the same time, this defect is of high severity because none of the other functionalities can be carried out.

Low Priority and High Severity:

A twisted scenario which rarely occurs but makes the application crash is an example of a low priority defect because user doesn’t come across this scenario normally and can be fixed later.

On the other hand, it is having high severity because it makes the whole application break and no functionalities can be performed.

Low Priority and Low Severity:

Spelling mistake in any of the words on some inner pages of the website that is rarely accessed is an example of low priority defect because it doesn’t matter much to the users as business is not impacted and can be fixed later. It is also having low severity because it is not impacting any functionality of the website.

I hope this clears the defect attribution. comments and questions are welcome.

A User review-Apple IPhone-4: I

Techie nerds, geeks or even company reviews are quite interesting and have their importance but a “User Review” is something which you won’t like to ignore; you should not. IPhone-4 was a buzz word since it’s release and I decided to provide a user review for IPhone-4.

So here you go:
iPhone4, Worlds Thinnest Smart Phone. One of the finest product. Best Smart Phone ever shipped. and a lot promising stuff about it, said by Apple.

As an “End User” I agree that its really cool product with loads of features. Monetory wise, I have paid nice 200$ on it and would be paying extra 600$ over the period of 2years for data plan, in order to make this Smart Phone work as “Smart Phone”.

Like with all the smart phones available today, if you want smart phone you need to be dumb and pay extra bucks to your carrier to access Internet. If you don’t want data plan, they won’t sell you with contract!! Quite annoying, as there are bunch of apps available which doesn’t need Internet. Can’t I just use them on my “Smart Phone”?

Enough, I have started review with good amount of criticism. But I have bought iPhone 4 and I am only criticizing it, its just not good. I bought it means I does like it. My criticism is for my expectations from IPhone-4.

Now, Let me list down some great features:
Multi touch: WOW!!!! For the first time users, yeah it was a major break through with first generation iPhone. Now, many of smart phones have them. But yeah still its most important thing.

iPod: Great!!!! Awesome sound quality.. I don’t doubt Apple but I still have a question; Isn’t that sound quality due to its Super Cool head phones? And ultimate Apple allowed users to create a play list right from iPod s/w. I dont know, weather I should be happy for this or surprised they allowed it this late.
🙂

Apps: Hundreds of thousands of Apps available, ranging from Games, Productivity, Social Networking, Business and so on. And good news is there are lot of free apps. If you dont consider going through iTunes or to-be specific Apple App Store, Its wonderful!! They will really make your phone smart.

Retina display: Again, WOW!!!! Its really nice. You can really see the difference if you compare 3GS and 4. I have done this. My friends have iPhone3 so I got to compare them.

Front Facing Camera: Kinda cool. It would be much cooler once we have apps accessing front facing camera and we can use chat tools to make video calls/chat.

I hope I would get some app soon (hopefully Skype, I would be free from sitting in front of my laptop and sit at one place.)

Let me clarify, I am not an Apple fanboy. I own one, so actually I should be writing much of it, but unfortunately as I get to use it

more I have started finding much of “TOBE MADE” improvements in it. I want more in my IPhone-4. I wish Mr.Jobs read this blog and add some features in next release.

I have bunch of things to say about which will ofcourse make IPhone-4 more than a perfact 10. I would have one separate post for it quite soon. Also, a comparison with my sweet SonyEricssion W550i music phone. My love for it has

increased after I started using iPhone. I guess Sony Erricson missed the bus, other wise they had real good features in walkman series phone.

Some of the iPhone still don’t have.. Surprised?? I will list them. Stay tuned…

To end the present user-review I will rate my IPhone-4, 7.5 / 10. A good product but lil’ improvement required.
