I am using Tomcat -5.0.25 , i had made an application named PED and placed it in the webapps so when i type http://localhost:8080/PED . The application is working fine. Now what i want is to do something so that when i type www.PED.com , the application should run. For this i read the Tomcat Docs came to know about Alias Tag in HOST. And also of appBase attribute form where our applications are found. I put the Alias Tag and gave the hello. And also changed the appBase attrib. to webapps/PED . Now i thought that writing http://hello:8080 would start my application but that didn't happened.Even only placing the Alias tag and trying http://hello:8080/PED didn't work . Please let me know about this and also how the port is mapped . ALso if possible let me know abt how SSL can be employed. I am in immediate need. Please help me out.
