   Module - specify the name of the application module, which
contains the file, which you want to update.
For example, it can be calc.war .

   File Name - specify the absolute file name of the file, which
you want to be updated, which means that this file exists in the module
you have been selected.
For example, if we want to update the web.xml of a WAR file, then
the File Name must be C:\fileForUpdate\web.xml, for Windows, which
means that this file will be used for the update action, so it must
exists on the file system.

   Mapping - specify the fully qualified entry name of the file,
which you want to be updated, in the application module.
For example, if we want to update the web.xml of a WAR file, then
the mapping name must be WEB-INF/web.xml, because according to the
specification it must be the archive entry of web.xml in the WAR file.

   Container - specify the name of the container, on which the
application module selected in Modul have been deployed. This container
must support the Single File Update action.
For example, it can be servlet_jsp.
