How to build a service

Axis2 supports 3 programming model

Create a service from scratch

• Write a class whose methods use OMElement as arguments and/or return type
• create a services.xml
• package  as a .aar file
• deploy

POJO for rpc-style services

优点：自己写客户端，容易出错，不用熟悉WSDL。

缺点：用此方法进行调试不容易

How to deploy a service

Often axis2 uses its own package named .aar, and the layout of this archive is like:

\---BookService
    \---META-INF
    |    services.xml
    |
    \---lib
    |    dependency1.jar
    |    dependency2.jar
    |
    \---com
        +---company
        |    Service.class
        |

But this is mainly for a standalone deployment scenario.

embedded in .war

Most of time, we embed our service into our web application and the service implementation will reuse the application logic.

In embedded mode, we needn’t package as a .aar. Just a directory in WEB-INF/services is OK.

\---book
    |   pom.xml
    |   README
    |
    \---src
        +---main
        |   |   log4j.properties
        |   |
        |   \---samples
        |       \---demo
        |               Book.java
        |               BookService.java
        |
        +---test
        \---webapp
            \---WEB-INF
                |   web.xml
                \----conf
                |        axis2.xml

                        \---META-INF
                                services.xml
