Building WSO2 Carbon from source is a simple task. If you follow the steps correctly you will get it. In the recent past some people have faced problems when building Carbon. Here in this post, I will give you steps to properly build Carbon from source.
- Jdk 1.5 or higher,
- Apache Maven 2.1.0 or higher
- Apache Ant 1.7.1 or higher.
> mvn clean install -Dmaven.test.skip=ture
Check out Apache Axis2 branch and build
> svn co http://wso2.org/repos/wso2/branches/carbon-platform/2.0/axis2
Before building Axis2 you need to build axis2-aar-maven-plugin and axis2-mar-maven-plugin in the modules/tools folder.
Check out Apache Axis2 Transports and build
> svn co http://wso2.org/repos/wso2/branches/carbon-platform/2.0/transports
Check out Apache WSS4J and build
> svn co http://wso2.org/repos/wso2/branches/carbon-platform/2.0/axis2
Check out Equinox P2 and build
> svn co http://wso2.org/repos/wso2/branches/carbon-platform/2.0/p2
WSO2 Carbon uses OSGi as its underlying modularization technology. Therefore Carbon uses a collection third party bundles. Most of these third party bundle are wrapped by WSO2, since they are not yet available as bundles. Carbon-orbit project contains all these third party bundles.
Check out and build Carbon-orbit
> svn co http://wso2.org/repos/wso2/trunk/carbon-orbit
Check out and build Carbon
> svn co http://wso2.org/repos/wso2/trunk/carbon
If you follow above steps correctly, you should be able to build Carbon without much problems. Please let us know if you find any issues.

- WSO2 Web Services Application Server (WSAS) 3.0
- WSO2 Enterprise Service Bus (ESB) 2.0
- WSO2 Registry 2.o
- WSO2 Business Process Server (BPS) 1.0
The WSO2 Carbon SOA platform uses OSGi as its underlying modularization technology. Therefore Carbon provides you all the benefits that OSGi provides. It supports the ability to plug in new components over time and also customize the middleware to support your enterprise architecture. For an example, you can add mediation capabilities to WSO2 WSAS with no effort. you just need to download the required plugins and install them into WSAS. It is that simple.
Adapt middleware to your enterprise architecture, instead of adapting your architecture to the middleware. Try WSO2 Carbon based products and see the real power of them. Let us know your comments

WSAS-v3.0-beta2 is the first WSAS release which runs on the brand new WSO2 Carbon platform. Just like the previous releases of WSAS, this release also capable of running as a standalone server and on top of other well known application servers. A step by step procedure to run it on Apache Tomcat is explained below.
Step 1 : Download WSAS-v3.0-beta2 binary distribution and extract it (say you extracted it to /home/foo/wsas). If you don't have an already extracted Apache Tomcat server, download and extract it too (say you extracted it to /home/foo/tomcat). Tomcat version 5.5.x or higher is recommended.
Step 2 : Copy 'repository', 'resources' and 'conf' directories from extracted WSAS folder and paste them into a separate folder (say /home/foo/wsas-home).
Step 3 : Set an environment variable of the name CARBON_HOME with the above folder path as the value (according to above example, CARBON_HOME=/home/foo/wsas-home). Then set the environment variable CATALINA_HOME with extracted tomcat folder path as the value (CATALINA_HOME=/home/foo/tomcat).
Note : If you want, you can use the folder to which you extracted WSAS (/home/foo/wsas), as WSAS_HOME without copying the above folders into a separate location.
Step 4 : Create a folder inside the 'webapps' folder (say with the name 'wsastest') of extracted Tomcat and copy the WEB-INF folder which is inside /webapps/ROOT folder of the extracted WSAS in to the created folder (copy /home/foo/wsas/webapps/ROOT/WEB-INF folder into /home/foo/tomcat/webapps/wsastest folder).
Step 5 : Open the server.xml file which is inside the conf folder of the extracted Tomcat (/home/foo/tomcat/conf/server.xml). Insert the following 'Connector' entry inside the 'Service' tag to set the HTTPS port.
Connector port="8443" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
acceptCount="100" scheme="https" secure="true"
keystoreFile = "/home/foo/wsas-home/resources/security/wso2carbon.jks"
Note : You can use any port instead of 8443 and you have to correctly set the path to 'keystoreFile' according to your CARBON_HOME.
Step 6 : Open the carbon.xml file which is inside CARBON_HOME/conf folder. It contains a ServerURL entry as shown below (line 47).
Edit the port and add the correct context. According to the example above, it should be as follows.
Step 7 : Open the axis2.xml file which is inside CARBON_HOME/conf folder. Go to line number 145 and change the http port to Tomcat http port which is 8080 (default port).
Then go to line number 160 and change the https port to what you have given above (8443).
Step 8 : Open a terminal and move into the bin folder of the extracted Tomcat and start the server using the following command.
On Windows : catalina.bat run
On Linux : sh catalina.sh run
Step 9 : Open your web browser and access the URL https://localhost:8443/wsastest/carbon. You will be directed to the WSAS home page through which you can log into the system.
- When the server starts up, you will see and exception regarding a data services sample. Please ignore it for now.
- Shutdown/restart option provided in the WSAS UI doesn't work in Tomcat. Therefore please use the shutdown option of Tomcat to shutdown and restart WSAS.

The WSO2 WSAS & WSO2 Carbon team is pleased to announce the release of version 3.0-beta2 of the Open Source WSO2 Web Services Application Server (WSAS).
This release is available for download at . WSAS is based on revolutionary the WSO2 Carbon  framework, Middleware a la carte'. Now you can adopt the middleware to suite your enterprise architecture. All the major features have been developed as pluggable Carbon components.
1. Based on the OSGi based WSO2 Carbon architecture. This is a unification of all Java based products from WSO2. Now you can have features from the lightweight super-fast WSO2 ESB & the super-cool WSO2 MashupServer, running on your WSAS instance. You can mix and match the functionality you require according to requirements of your enterprise. The middleware can be adopted to your architecture. You could even extend the middleware by developing your own middleware components.
2. Enhanced admin UI
3. Extensible server admin framework
4. Separable frontend & backend - a single frontend server can be used
to administer several backend servers simultaneously
5. Various bug fixes and enhancements.
The full feature list is available at
How to Run
1. Extract the downloaded zip
2. Go to the bin directory in the extracted folder
3. Run the wso2server.sh or wso2server.bat as appropriate
4. Point you browser to the URL https://localhost:9443/carbon/
5. Use "admin", "admin" as the username and password.
6. If you need to start the OSGi console with the server use the property -DosgiConsole when starting the server
1. Data Services definition wizard is not available
All known issues have been filed here . Please report any issues you find as JIRA entries.

Expect the WSAS 3.0 release in mid December this year. The most significant feature in this release is going to be the fully componentized architecture. This new release is going to be based on WSO2 Carbon, which is the base platform for all future Java products from WSO2. WSO2 Carbon is based on OSGi. All the major features have been bundled into Carbon components which are in fact OSGi bundles. All major middleware vendors, including WSO2, have recognized the power of OSGi and are migrating their products towards an OSGi based architecture.
What is the value & benefit this is going to give the WSAS users & in general the Carbon users? Well, there are several.
Pick & Choose
1. Ability to select only the bare minimum functionality needed. You can simply remove unnecessary functionality
2. Ability to extend the server's functionality. For example, if you have a running WSAS instance, and need some service mediation capabilities enabled or BPEL capabilities, you simply need to drop in the relevant Carbon components into the Carbon plugins directory. You do not need to restart the server.
In short, you can mix & match whatever the functionality you desire.
Improved Availability - Server Restarting Minimized
Let's say you have enabled data services support through the Carbon Data Services component, and that your server is running in a production system. You need to deploy a data service which talks to a MS-SQL Server RDBMS, but have not included the JDBC driver in the WSAS instances classpath. In a traditional deployment, you'd need to drop the JDBC driver jar file into the classpath & restart the server, thereby impacting the availability. With the Carbon based approach, restarting is no longer required. Carbon takes care of wiring in the new MS-SQL Server JDBC driver.
Extend the server's functionality through custom components
The users can write their own components & extend the functionality of a Carbon based server.
What are the benefits this approach gives to the middleware vendor? The greatest benefit is having the ability to go from concept to solution in the minimum possible time period. For example, the BPEL Carbon was developed within 3 weeks! We did not have to rethink how to secure the BPEL processes & provide other enterprise features. These were already available as Carbon components. This benefit is also directly passed on to the Carbon user since they can expect to get new functionality within the shortest possible period.

I recently came across an interesting article on TSS aptly titled "What is an App Server?"
The traditional mindset has been, App Server = J2EE App Server, but that is changing now. As mentioned in that article,"an application server provides an environment where applications can run, no matter what the applications are or what they do"
