Without creating an application directory structure how would you run an individual jsp file?
Create a folder "myapplication" within C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\ and place your jsp file in it.
This is how the file path looks C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\myfile.jsp
Now start the TOMCAT server.
Use the following url in your browser to run the jsp file.
