I have modified the server.xml file to match the change I made in JIRA to the configuration base url. I NEED it to say:
http://newjira.rmls.com/jira to open the new JIRA program.
Below are the modifications I made to the server.xml file - and now I can''t open anything 
<Connector port="8009" redirectPort="8443" enableLookups="false" protocol="AJP/1.3" URIEncoding="UTF-8"/>
-->
<Engine defaultHost="newjira.rmls.com" name="Catalina">
<Host appBase="webapps" autoDeploy="true" name="" unpackWARs="true">
<Context docBase="${catalina.home}/atlassian-jira" path="/jira" reloadable="false" useHttpOnly="true">
Can someone please point me in the right direction? I am new to JIRA! and we just upgraded from 4.0.1. to 5.2.8 - and I believe this is my last stumbling block. Thanks.
