WSO2 AS is the oldest WSO2 product. Initially it was started as “WSO2 Tungsten” and then renamed to “WSO2 Web Services Application Server” and then to “WSO2 Application Server”. There are plenty of past members of the team who contributed a lot to the success of the product and I should thank all of them. Azeez (Currently the Director of Architecture) was the first product manager of WSO2 AS and he did a great job in getting the product into this level. And also people like Saminda, Chinthaka, Deepal, Sumedha, Amila and Sameera were some of the past members who has contributed a lot to the success of the product. In addition to that, I should thank SupunM who’s currently working full time on WSO2 AS.

So the next step will be the APICTA competition in which the best products from lot of other countries compete for the best of the best. Looking forward to do our best in that as well.

WS-BPEL is used to implement business processes in which different systems are integrated together through their Web Service API’s. It is a complete XML based language which supports lot of functions in the language itself. The complexity of the business processes implemented using BPEL can vary from very simple short term processes to long running processes which can run for weeks or months.

Being an XML based language has some advantages as well as disadvantages. Following are the most important advantages.

• No need to compile
• Being a well known standard
• Usage of XPath, XQuary etc.

• Inbuilt Data Services support
• Server Roles Management feature
• Deployment Synchronizer for easy Cluster configuration
• Improved JAX-WS Support
• Improved SOAP Tracer
• Improvements in Service listing page
  • Two lists for Services and Service Groups
  • Security Indicators within service list
• Improved Samples and documentation
• Improved Class loading for Web apps and Web Services
• Embedded Tomcat 7.0.14 support
• Servlet API 3.0 support

Then I searched for different options and found this post very useful. It is written for Ubuntu 8.10. But it works for any version of Ubuntu.

I’m playing for Legion and we were good enough to reach the finals this time. But unfortunately ended up losing to Wild Boars by 2 points in the finals. This post by Heshan explains the entire story and I’m not going to repeat it. But I’m trying to explain what I felt after the match.

This is the 3^rd annual WSO2 BB tournament. In 2008 and 2009, Legion were only able to reach the third place. So this was our first finals and we reached it by beating the defending champions, Titans. Last first round match was played between Legion and Titans on the 21^st of October and we needed to win it with a 10 points lead to reach the finals. That was one of the best days for Legion and we won by 11 points and reached the finals. I think we scored our last basket within last 10 seconds of the match and we had our share of luck on that day. We were thrilled and had some hope about the finals as well. Because, Titans is the only team which has four great shooters Lahiru, Sameera, Supun and Akila.

I think we played extremely well in the finals as well. Charith was amazing with his shooting accuracy and Waruna was rock solid with his defense as always. Dr. Sanjiva lead from the front and guided us really well. I also could support with few baskets. As Heshan has already mentioned in his above post, we didn’t know that the match is going to end until the referee’s final whistle. When there were 30 seconds to go, scores were level at 42:42. I was defending Samisa and he had the ball in his hand and just threw the ball from about 10 meters from the basket. I didn’t try to disturb him because the chance of scoring from that distance is minimal. But unfortunately for us, it went into the basket and didn’t even touch the ring. If I knew that we were within last 30 seconds, I could’ve easily defended him. So we didn’t have our share of luck and they had. Other than their luck, they had a fabulous player in Heshan who almost pulled the game alone. I think he scored more than 30 points out of their 44.

So that’s what happened on that rainy and hot night. Actually it was a brand new experience for me. Because, I’ve never represented my school or university in any sporting event. So this is the first time I understood how a sport can inject spirit into you. It’s amazing how you get pumped up in such an atmosphere with a big crowd. I know I’m still a baby when it comes to BB . But still I felt how thrilling it is to become a sportsman and represent your house, school, country or what ever it is. In summary, I didn’t have that feeling on the day I got 3A’s in my Advanced Level examination or on the day I won the gold medal for best academic performance in CSE.

So finally I have a small message. If you are only 12, 13, 15 years old and schooling, go ahead and play whatever sport you can for your school. It will never ruin your studies and will inject the strength to face the world. It will immensely help you to develop your personality.

In addition to that, I was hoping to buy a dongle to use when I’m at home (in Galle). But my new Nokia 5630 provides that capability as well . It can act as a dongle (HSDPA). So I activated a data package for my already existing Dialog connection and now using my phone as a perfect dongle. And also it works without any trouble in Ubuntu 9.04. It’s just plug and play.

If I bought a separate dongle, it will cost me nearly 10,000 LKR including the connection. But my Nokia 5630 saved me that amount while providing a great mobile phone experience with all the needed features for me. So if you are looking for a Nokia phone, go for it. It’s just great.

Note : This HSDPA functionality can be found in some other Nokia models as well. Ex : 5320, 5730, 5800, 6120

All our Carbon based products internally uses WSO2 Registry as a repository to persist data. For example, in WSAS all data about services, modules etc are stored in the Registry to make sure the same state is maintained even after restarting the server. And also, user is provided with a Registry browser and allowed to store whatever data he needs. This is model used in all our previous releases of Carbon.

In the upcoming 3.0.0 release, this Registry is separated out into three parts to perfectly suite our platform story.

1. Local Data Repository – This Registry instance is internally used by the server to persist instance specific information. These can be logs, transport information etc.
2. Configuration Registry – This Registry instance is shared across a cluster which contains several identical instances of Carbon. Data which should be shared by all nodes in the cluster are stored in this Registry. For example, in a WSAS cluster, data on services, modules etc. are stored here. In addition to that, all Carbon component specific information are also stored here.
3. Governance Registry – This Registry instance is shared across the entire platform. In other words, a complete SOA setup can contain few clusters of different products which together form a SOA platform. So this Governance Registry instance is used completely by the user to centrally manage stuff. For example, WSDLs, policies etc. which should be shared across the platform. 

By default, all these 3 registries reside in the same physical registry instance. Local data repository is always an embedded registry instance. User is allowed to configure Config and Governance registry locations through the registry.xml file. In other words, those can be pointed to remote registry instances.

This feature is already completed in Carbon 3.0.0 and will be coming out in March. This will be a great advantage for the users who are developing complete SOA solutions.

First of all, you have to use the BindingType annotation to set the SOAP11 MTOM binding as follows.

@BindingType(SOAPBinding.SOAP11HTTP_MTOM_BINDING)

After that, you can use javax.activation.DataHandler to represent your binary data in your parameters or return types. A simple MTOM enabled JAX-WS service class can be written as follows.

@WebService(serviceName = “MTOMSampleService”,
targetNamespace = “http://mtom.jaxws.wso2.org”
)
@BindingType(SOAPBinding.SOAP11HTTP_MTOM_BINDING)

public class MTOMService {

@WebMethod(action = “urn:uploadFile”)
public String uploadFile(DataHandler data) {
try {
InputStream is = data.getInputStream();
….
String msg = “File ” + data.getName() + ” of type ” + data.getContentType() +
” successfully received”;
return msg;
} catch (IOException e) {
e.printStackTrace();
}
return null;
}

@WebMethod(action = “urn:getTestData”)
public DataHandler getBinaryTestData(String stmtId) {
byte[] testData = new byte[10240];

for (int i = 0; i < testData.length; i++) {
testData[i] = 0x7f;
}

ByteArrayDataSource bds = new ByteArrayDataSource(
testData, “application/octet-stream”);
return new DataHandler(bds);

}

}

DataHandler objects can be used inside wrapped classes as well.
