Obtaining the Product

Follow the instructions below to download WSO2 ESB. You can download from the ESB web page or from the Linux command line. You can also download and build the source code.

Downloading from the Web page

In your Web browser, go to http://wso2.com/products/enterprise-service-bus/.
If you are a new user downloading WSO2 products for the first time, register and log in.
Once you are logged in, click the Binary button in the upper right corner of the page.

The binary distribution contains the ESB binary files for both MS Windows and Linux operating systems, compressed into a single ZIP file. This distribution is recommended for many users.

Downloading from the command line using Wget

If you have Wget installed on your computer, you can use it to download the binary distribution directly from the command line.

On Linux, establish a SSH connection to the Linux machine or log in on the text Linux console. On Windows, open a command prompt.
Use the wget --user-agent command as follows to download the binary distribution installation (WSO2 does not allow anonymous downloads):
```
wget --user-agent="testuser" http://dist.wso2.org/products/enterprise-service-bus/4.7.0/wso2esb-4.7.0.zip
```

Building from source

WSO2 invites you to contribute by checking out the source from the Subversion (SVN) source control system using the following commands. For information on using Subversion, see http://svnbook.red-bean.com.

You can download the complete WSO2 Carbon platform, which is recommended if you intend to modify the source. You can check out the complete source anonymously from SVN with the following commands (note that this version of the ESB is based on Carbon 4.0.5). The Carbon project comes in three sub projects: Orbit, Kernel, and Platform. Download and build them in that particular order.

Orbit:

$ svn checkout https://svn.wso2.org/repos/wso2/carbon/orbit/tags/4.0.5 wso2carbon

Kernel:

$ svn checkout https://svn.wso2.org/repos/wso2/carbon/kernel/tags/4.0.5 wso2carbon

Platform:

$ svn checkout https://svn.wso2.org/repos/wso2/carbon/platform/tags/4.0.5 wso2carbon

Following are the commands you can run to create complete release artifacts of WSO2 ESB, including the binary and source distributions. If you only want to build the ESB, use the -Dproduct=esb option as shown. If you want to build the entire Carbon core project, omit the -Dproduct=esb option.

This command...	Creates...
`mvn clean install -Dproduct=esb`	The binary and source distributions
`mvn clean install -Dmaven.test.skip=true -Dproduct=esb`	The binary and source distributions, without running any of the unit tests.
`mvn clean install -Dmaven.test.skip=true -Dproduct=esb -o`	The binary and source distributions, without running any of the unit tests, in offline mode. This can be done only if you've already built the source at least once.

If you are a committer, you can commit your changes using the following command (SVN will prompt you for your password):

$ svn commit --username your-username -m "A message"

Access through a firewall

If you are behind a corporate firewall that is blocking HTTP access to the Subversion repository, you can try the developer connection:

$ svn checkout https://svn.wso2.org/repos/wso2/trunk/carbon carbon

Access through a proxy

The Subversion client can be configured to access through a proxy. Specify the proxy to use in the "servers" configuration file in:

"~/.subversion" directory for Linux/Unix
"%APPDATA%\Subversion" hidden directory for Windows. (Try "echo %APPDATA%")

The comments in the file explain what to do. If you don't have this file, get the latest Subversion client and run any command. It will create the configuration directory and template files.

For example, edit the 'servers' file and add something similar to the following:

[global]
http-proxy-host = your.proxy.name
http-proxy-port = 3128
