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. If you want to globally engage a particular module, click Manage > Modules > List. On the Deployed Modules page, you can globally engage any listed module.
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_5_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.
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.
The WSO2 Carbon 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.
You can perform the following actions on engaged modules
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.
Figure 3: Throttle Configuration
After you have engaged a module (for example, throttling), the Global Configurations page will be updated. (Figure: 4)
There are some modules (for example, savan), doesn't have a global configuration page. But those can be globally engaged, just by clicking on the Engage action and can be disengaged by clicking on the Disengage action.
