/**
*
* Standard Axis2 service Deployer which use services.xml file to build
* services. ServiceDeployer can be used with Axis2 archive (.aar) or exploded
* directory structure. Some of the example formats given below.
*
* Examples :
*
* - repository/services/SimpleService.aar/meta-inf/services.xml
* - repository/services/SimpleService/meta-inf/services.xml
* - WEB-INF/services/SimpleService.aar/meta-inf/services.xml
* - WEB-INF/services/SimpleService/meta-inf/services.xml
*
*
* Further ServiceDeployer can be used to deploy services from a remote
* repository or load a repository from a JAR file. In this case service files access through URLs.
* To deploy services from a remote repository or JAR file it is expected to
* present service/services.list file which contains names of services.
*
* Example :
jar:file:/home/resources/repo.jar!/repo/services/services.list may contains following
* list of service.
*
* - StudentService.aar
* - SimpleService.aar
*
* 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.
