Creating the services.xml File
Create the Axis2/Java Deployment Descriptor file (services.xml) to instantiate the SpringInit
and EmpInfo services.
To create the services.xml file, complete the following steps:
1. Create the services.xml file in the EmpInfo/WebContent/META-INF directory, as
explained in the
Creating the EmpInfo-servlet.xml File section in the Getting Started
with Spring section.
2. Modify the services.xml file to include the instances SpringInit and EmpInfo services.
After modification, the services.xml file must appear as:
<serviceGroup>
<service name="SpringInit" class="com.hp.empinfo.service.SpringInit">
<description>
This web service initializes Spring.
</description>
<parameter name="ServiceClass" >com.hp.empinfo.service.SpringInit</parameter>
<parameter name="ServiceTCCL" >composite</parameter>
<parameter name="load-on-startup" >true</parameter>
<operation name="springInit">
<messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>
</operation>
</service>
<service name="EmpInfo">
<description>
Spring EmpInfo Axis2 AAR deployment
</description>
<parameter name="ServiceClass" >com.hp.empinfo.service.EmployeeDao</parameter>
