How to plug service hosting components in to WSO2 ESB

With the revolutionary WSO2 carbon framework, plugging in service hosting components in to WSO2 Enterprise Service Bus (ESB) is just a matter of seconds! It is extremely simple.

WSO2 ESB is an message mediation framework and the service endpoints usually hosted in a separate JVM. However there may be requirements to host the services inside ESB. There are different types of services you can deploy in a service container.

Axis2 web services
Pojo services

EJB services

Data services

Spring web services

Axis1 services
JaxWS services

Now, you can add any of these service hosting components in to your ESB. Lets see how it can be done.

1. Download WSO2 Enterprise Service Bus (ESB) -2.0 beta2
2. Extract the downloaded zip
3. Go to the bin directory in the extracted folder (ESB_HOME/bin) and run wso2server.sh or wso2server.bat
4. Point you browser to the URL https://localhost:9443/carbon and login as an admin (Use "admin", "admin" as the username and password)

5. Suppose you want JAXWS services are hosted in ESB. Then you need to have the jaxws service hosting components. You will be able to download the individual components from WSO2 Oxygen Tank soon. However, we will downlaod WSO2 WSAS-3.0-beta2 and get the components from it. Therefore, please download WSO2 WSAS 3.0-beta2 and extract the downloaded zip file in to local file system. (Lets name the extracted directory as WSAS_HOME)

6. Go to WSAS_HOME/webapps/ROOT/WEB-INF/plugins. You will find a lot of libraries inside that directory.
Copy org.wso2.carbon.jaxwsservices.ui_SNAPSHOT.jar, org.wso2.carbon.jaxwsservices_SNAPSHOT.jar and org.wso2.carbon.jaxws-2.1.jar files and paste them into ESB_HOME/webapps/ROOT/WEB-INF/plugins
7. Restart WSO2 ESB server
8. Log in to ESB management console again. You will find the JAXWS service component is listed in the left menu.

In this way, you can add any of the above service components into ESB. For example, if you want Axis2 service component inside ESB, you just need to copy org.wso2.carbon.aarservices-SNAPSHOT.jar and org.wso2.carbon.aarservices.ui-SNAPSHOT.jar as explained above.

A software architect's view on WSO2 QA methodology

Afkham Azeez, a software architect at WSO2 nicely puts together his observations of Quality Assurance practices by comparing them with the traditional QA processes.
As I always believe, the feedback of QA tasks must be come from the development team first. In an agile software process, it is really important to have feedback from the collegues of your team. You work with them. They know your approach and how you carry out your duties than the other hidden managers. Therefore, a good feedback from development team is definitely help a QA team to move forward.
I totally agree with Azeez on his idea on traditional vs agile/collaborative QA. We don't want our QA engineers to spend their valuable time filling huge excel sheets and writing comprehensive plans which are not even looked at during the test execution phases. Instead, our QA engineers learn SOA technologies, involve in community discussions, maintain technical blogs, researching on testability of features etc.. They are in a position to take over the QA testing of any SOA middleware with minimum ramp-up time. Since traditional QA people don't even look at the source code, our team write clients to invoke web services in reliable/secure manner, write DB scripts to port our products to run on different DBMSs and help developers in minor bug fixes during rush release cycles.
I must appreciate Azeez for sharing his view on QA which will help us to do a better job.
