there are deploying the two ways but i suggest the only one
of the easyist way that is there are several steps
steps:
1)   first create the one of the own directory name
         example: owapp
   next step
2)  in this directory static resousrce are store the in (owapp) 
        example: html code
3)  next step in owapp directory create the two
subdirectories that is one is LIB directory in this
directory store the XML files and  create the second
subdirectory CLASSES directory in this directory store the
sevletclasses and jar files 
4)after above processes completed then this total directory
copy to the total directory of (owapp) one the web server
for example i take the tomcat server in this server one of
the directory is WAPP store the total directory of OWAPP
store the in the WAPP folder 
5) after completed deployement then we type the url name on
one of the browser i am using the browser netscafe navigator
whenever we press the enter button after enter the enter
button first we call XML file

There are tow types of deployments. 
1. Hard deployment
2. Soft deployment

After compling the code, copy and past the foder structure directly in the server (Ex webapps folder in tomcat) is called Hard deploment.

Creating the folder as .war file and deploying it through admin console is the Soft deployment. 

Later one is the most perferable one.
