The WSO2 SOA platform has the capabilities of Axis2 to add modules to extend it. A module is an archive file that bundles a set of classes, related libraries and third party library dependencies. The module configuration functionality is provided by the Module Management feature which is by default bundled in the Service Management feature of the WSO2 feature repository. The module management feature provides a user-friendly interface to engage, disengage and configure modules in 4 levels as follows.
In all four levels, specific module engagement steps are the same from step 4 onwards in the service-level module engagement section described here.
- Global Level - A module will be engaged for all the services. For information on how to access global-level Axis2 module configuration windows, refer to section Axis2 Modules.
- Service Group Level - A module will be engaged for a service group. For information on how to access service group-level module configuration windows, refer to section "Service Management -> Accessing Service Groups."
- Service Level - A module will be engaged only for a certain service as described below.
- Operations Level - A module will be engaged for a particular operation of a service. For information on how to access operation-level module configuration windows, refer to section Operation Management.
Note
To upload your module archive, all the class files and the module.xml descriptor file have to be available in the archive.
