Hello there!!

Sorry but I have not developed this application, but as the nsame says:

com.xand.reina.servlet.GetConfigurarAlumnosServlet >> means >> com.xand.reina.servlet.Get "Gonfigure" "Student" Servlet

The problem is that applications is been working fine since few weeks a go... so, what can be?

Thanks!
