Changes in the Server.xml file of Tomcat

If you are performing the challenge in a personal edition or in a VM machine, perform the following changes to the server.xml file.

1. Pega Personal Edition (on Windows) will be installed in C:\PRPCPersonalEdition.
2. Open server.xml file from C:\PRPCPersonalEdition\tomcat\conf.
3. If using VM – Linux Lite, the server.xml file is located at /opt/tomcat/conf.
4. Search for the connector port and set it 80, with the following changes:

   <Connector port="80" protocol="HTTP/1.1"           
     connectionTimeout="20000"             
     redirectPort="8443" />

5. Search for the default host and enter an address with .com to act as your domain <Engine name="Catalina" defaultHost="www.pegaopenid.com">
6. In the same server.xml file, search for host name and give the same name.

   <Host name="www.pegaopenid.com" 
   appBase="webapps"          
   unpackWARs="true"
   autoDeploy="true">

7. After making the changes, save the server.xml in Tomcat.
8. In the hosts file, enter the following line:

• If Windows: C:\Windows\System32\drivers\etc\hosts
• If VM- Linux lite: /etc/hosts

      127.0.0.1 www.pegaopenid.com (name as given in the server.xml)

After making changes to the files, you can now access the personal edition with a domain name (no need for the port number).

• http://localhost:8080/prweb -- earlier
• http://www.pegaopenid.com/prweb -- after changes to server.xml and hosts file
