/**
*
* Standard Axis2 Module Deployer which use module.xml file to deploy
* Modules. ModuleDeployer can be used with Axis2 Module archive (.mar) or exploded
* directory structure. Some of the example formats given below.
*
* Examples :
*
* - repository/modules/LogModule.mar/meta-inf/module.xml
* - repository/modules/LogModule/meta-inf/module.xml
* - WEB-INF/modules/LogModule.mar/meta-inf/module.xml
* - WEB-INF/modules/LogModule/meta-inf/module.xml
*
* Further ModuleDeployer can be used to deploy Modules from a remote
* repository or load a repository from a JAR file. In this case module files access through URLs.
* To deploy Modules from a remote repository or JAR file it is expected to
* present modules/modules.list file which contains names of Modules.
*
* Example :
jar:file:/home/resources/repo.jar!/repo/modules/modules.list may contains following
* list of service.
*
* - LogModule.mar
* - Addressing.mar
*
*
* There are several approaches available to set repository URL to Axis2 run
* time. As an example one can provide repository URL as a init-param of
* AxisServlet. Some of the examples given below.
*
* -
*
Example -1 :
*
* {@code
* axis2.repository.url
* http://localhost/repo/
* }
*
*
* -
*
Example -2 :
*
* {@code
* axis2.repository.url
* jar:file:/home/resources/repo.jar!/repo/
* }
*
*
*
*
* NOTE - It is discouraged to use above services.list based deployment approach
* because it does not support hot-deployment, hot-update and some of other
* important deployment features as well.
*
