[Axis2] How to check when i uploaded a service and/or a new version of the service to axis2?

hello to everybody:-

I will put my questions into few steps :)

Step1: I uploaded a service named foo to axis2 server, lets say i used
tomcat to do so. (but it could be simply putting the .aar file)
Step2. I made some changes to the service foo (using eclipse or netbeans),
compiled and build a newer version (with the same name)
Step3: I upladed foo again to the axis2 server (lets say i used tomcat to
do so).

Question: Is there any way to know that I uploaded foo two times to the
axis2 server???
Moreover, Is there anyway to know that the schema of foo is changed, i.e.,
the second foo contains additional methods?


I would like to know if there are any handlers or modules in Axis2 which i
can write or configure to answer the question..

any help would be really appreciated...
