 <P>Service Groups are a brand new concept introduced by Axis2. With
 Service Groups, users can group several services together. This
 concept gives two main advantages to users.</P>
 <OL>
 	<LI><P>Several related services can be easily managed and deployed.</P>
 	<LI><P>Can share information between different services of the same
 	Service Group at run time.</P>
 </OL>
 <P>This sample application demonstrate how you can create a service
 group and how you can use the functionalities offered by axis2 to
 share information between services of the same group at runtime.</P>
 <P><BR><BR>
 </P>
 <P><U>The idea</U></P>
 <P STYLE="text-decoration: none">The ides behind the sample is pretty
 simple. We have developed a Calculator service group with three
 services AddService, SubstractService and MultiplyService. Each
 service has two operations. For e.g. AddServices has a 'add'
 operation and a 'addPrevious' operation.
 </P>
 <P STYLE="text-decoration: none">The 'add' operation is used to add
 two integers and produce a result. When a operation is run the result
 will be saved in the current ServiceGroupContext which is the Context
 that has to be used to share information between services of the same
 service group.</P>
 <P STYLE="text-decoration: none">When the addPrevious operation is
 run (which takes a single integer as the parameter) the saved value
 of the last operation will be added to the integer values that comes
 as a parameter.</P>
 <P STYLE="text-decoration: none">You can even call operations of the
 other two services. These services can also use the value saved from
 the previous operation.</P>
 <P STYLE="text-decoration: none">You can use the client class
 provided to run this in a interactive manner.</P>
 <P><U>How to run the sample</U></P>
 <P>Please run axis2 and deploy the provided Calculator.aar service by
 simply dropping it to the Axis2_webapp/WEB-INF/services directory (see
 axis user guide for more details).</P>
 <P>Run the run.bat file.</P>
 <P>You will see the following screen.</P>

 <P>Now select the service. + for AddService, - for SubstractService,
 * for MultiplyService. And press enter.

 <P>Enter the two parameters.</P>
 <P>You will see the result.</P>

 </P>
 <P>Now select the option 'c' to continue the round. Select the
 operation. You have to give a single parameter and press enter.</P>
 <P>The result will be generated using the entered valus and the
 result of the previous operation (which is obtained from the
 ServiceGroupContext).</P>
