I'd recommend dropping the context definition in your server.xml. Under
normal conditions you should never have to modify that file except to
alter server-wide settings like which ports it listens on.
Also looking at your axis2/META-INF/context.xml file, I see the port
number is incorrect.
Lastly, I would recommend you drop the autoReconnect parameter of your
database url and add validationQuery="select 1" to your Resource
element. Autoreconnect is of minimal usefullness and validationQuery
can test the db connection before your app attemps to use it.
