Global Configurations
The WSO2 SOA platform has the capabilities of Axis2 to add modules to
extend its capabilities. The global modules will affect all the services
deployed within the server.
Note: If you want to engage the
modules through a service, in the navigator, under Modules, click List. On the Deployed Modules page,
you can select the modules you want to engage.
Deploying Module Archives (.mar)
A module is an archive file that bundles a set of classes, related
libraries and third party library dependencies. The WSO2 Carbon provides a user
friendly interface to engage, disengage and configure these modules. You can
learn more about Axis2 modules from the Axis2 manuals at: http://ws.apache.org/axis2/1_4_1/modules.html
To upload your module archive, all the class files and the module.xml
descriptor file have to be available in the archive.
The folder structure of
the module archive file will look as follows.
Test.mar
META-INF
Module.xml
TestModule.class
TestHandler.class

Figure 1: Uploading a module achieve file.
- In the navigator, under Manage/Modules, click Add. The
Add a Module page appears.
- Click Browse to select the module archive file (.mar)
you want to upload.
- Click Upload.
If the file was uploaded successfully, a message will appear prompting
you to restart the server to activate the module.
- Click
OK.
Once the server has been restarted, the module will be active and displayed
on the
Deployed Modules page. You can engage, disengage or
delete the module as required.
Listing of Globally Engaged Modules
The WSO2 WSAS management console provides you with an interface to engage,
disengage, configure or delete available modules.
The module list contains the following entries for each module.
- Name
- Version
- Description
- Actions
You can perform the following actions on each module
- Disengage: If the module is already engaged, you can disengage the
module.
- Configure: Some modules can be configured. Use this option to access
the configuration panel of these modules.
- Engage: If the module is not already engaged, use this option to engage
the module.
- Delete: Delete the module
Global Configuration UI before engaging a module

Figure 2: Available modules
All the available modules are shown above the currently engaged modules.
The WS-Addressing module is always globally engaged. This list will be
updated when you engage other available modules.
For example, the Throttle module is available to be configured globally.
Once you click the Configure icon, a new page appears with the configuring
options available for that module.
Throttle Global Configuration UI

Figure 3: Throttle Configuration
After you have engaged a module (for example, throttling), the
Global Configurations window will be updated.
(Figure: 4)
The icon in front of an already engaged module, will have a red mark to
indicate that it can be disengaged or reconfigured by clicking on that
icon.
