User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.7) Gecko/20100723 Fedora/3.6.7-1.fc13 Firefox/3.6.7 Trying to run the manager application from the "Tomcat Manager" link in the "Administration" pane on the left leads to a HTTP 404 error page. Reproducible: Always Steps to Reproduce: 1. sudo yum install tomcat6-webapps tomcat6-admin-webapps 2. sudo service tomcat6 start 3. Visit http://127.0.0.1:8080/ in a web browser. 4. Click the "Tomcat Manager" link in the "Administration" pane on the left of the tomcat test page. Actual Results: An error page is displayed with the following contents: HTTP Status 404 - /manager/html type Status report message /manager/html description The requested resource (/manager/html) is not available. Apache Tomcat/6.0.20 Expected Results: The manager application page should display normally. Following up the catalina.out log file in /var/log/tomcat6, it seemed some xml files, like manager.xml, that were used to existing under /etc/tomcat5/Catalina/localhost as part of the tomcat5-admin-webapps package no longer exist under /etc/tomcat6/Catalina/localhost as part of the corresponding tomcat6-admin-webapps package(or any other package).
After further investigation, I found out that the problem related to file permissions on /etc/tomcat6/Catalina(and consequently on its subdirectory localhost). This was earlier illustrated in bug 574593. *** This bug has been marked as a duplicate of bug 574593 ***
