I am new to struts , i just want to know how many validator xml files can there be in a particular application . I also want to know what are the other xml files that are used in this framework
There can be an arbitrary number of validation config files and struts config files. Other config files depend on what other components you're using; Tiles adds another arbitrary number of config files.
The same is true for Struts 2 (you said struts-config, which is a Struts 1 config file name), although it's not necessary to have any XML config files at all.
