Tutorial on Axis2/C codegen (WSDL2C) tool

Finally I managed to write a simple step by step tutorial on how to use WSDL2C tool in Axis2/C. Visit it here, http://wso2.org/library/3534.

Axis2/C Architecture

I found a discussion on Axis2/C user list about the references where you can find information on Axis2 Architecture and Damitha in the axis2/c list have posted list of great resources. Looks like the mail achieves think it is a junk message due to the bunch of links, So I thought it is better I can publish the list here, hopefully this will be useful for future users..

Be aware of Terrorists

Yesterday (in Sri Lanka) there was a bomb blast in a bus, followed by two today one in Zoo, one in Colombo railway station targeting civilians. There are no any argument that only LTTE terrorists can do these kind of ruthless attacks.

No matter whoever do this, as responsible citizens we have to think what we can do to prevent or at least minimize this. Just ignore the country, at least to save our selves we should be able to do something.

From these and the past incidents it is obvious that terrorisst mostly target public places and public transport. Well I personally very rarely visit public place. But I always travels in public transport. I have to travel a long distance at weekends to visit my home and back, and short distance to go to my office and back to boarding place.

From these two kind, I mostly concern about my long distance travel since yesterday and some reason attacks were done on long distance buses specially when traveling in early morning. I and my Friend Omega who also ride long distance at every weekend had a little discussion yesterday on this subject. According to him, ( I also agree with him) there is a high probability that somebody can put a bomb bag in an early morning bus, because

1. Almost all the ppl sleep in the buses traveling in the morning (the ones who not standing), so no one notices if anything strange happens..
2. There are a lot of ppl traveling in the morning so the buses get crowded.

What we can do is simply ask bus conductor to check the bags of whoever want to come in. But this is not happening, It will delay the ride, and course people angry (NOTE, There are percentage of people who are really angry showing their bags for no reason) . Anyway we can ask conductor to do that just for our safeness. So we can at least make sure that there will be no blasting inside the bus.

Not only Government, But also normal ppl like us should do our maximum to halt terrorists acts and bring the peace to our country.

Shameless publications of a dying Terrorist Group

Sri Lanka is about to win the war against LTTE terrorists. Meanwhile these terrorists are trying to do all sort of things to show that they are still alive.
Hm. But the Internet seems a very difficult place to cheat.:)

Extracted from feedbacks on tamilnet.tv.

1. Here is a tiger terrorists publication last Wednesday, they claims it is a photo of Sri Lanka Government soldier. And they named that is the body of N.Kumara, a local name.
Funny thing is same photo have been published 18 months ago here. It is a body of a soldier in Iraq.

2. Here in tamilweek web site the image is named as it is an air crafts of LTTE. But here the same picture posted in the India Air Force web site.

They spend six years cheating World (But not Sri Lankan, I mean people who are living in Sri Lanka) with the Cease fire agreement. The cheat will not last long..

Amazon Online Shopping with Web Service Framework for PHP

I finally managed to submit my first article for WSO2 Oxygen Tank. It is about how to do online shopping with Amazon Web Services using Web Service Framework for PHP.

There I'm demonstrating how to write a simple client library to access Amazon Web Services and how to use that library to write your own application to do online shopping with Amazon.com

There I attached the Client library code and two sample applications, one very simple php command line application and the other much improved web application. Hope this will be useful to people who are interested in working with WSF/PHP.

Select you service operation parameters..

In Web Service Framework for PHP 1.2, when you are writing a service using WSService with a WSDL, you always had to specify the type of the operation parameters to be "MIXED". But it would have been more convenient that the 'MIXED' to be default for ther service operation parameters when WSDL is specified.

So yesterday I took some minitues and change the logic so that,

1. When the WSDL is specified, the opParms would be default to "MIXED"
2. Otherwise, the opParams would be default to 'WSMESSAGE'.

So wsdl-mode code will be simplified to this..

function QueryPurchaseOrderFunction($pro_name, $quantity, $date, $orderNo) {
     // the business logic.

}

$operations = array("QueryPurchaseOrder" => "QueryPurchaseOrderFunction");

// The following line is not required

// $opParms = array("QueryPurchaseOrderFunction" => "MIXED")

$svr = new WSService(array("wsdl"=>"sample_wsdl_11.wsdl",
                         //opParams" => $opParams; // This too not required

                          "operations" => $operations));
