Description of problem: After installing pki-ca package from yum repository on Fedora 8, and visiting the configuration URL (http://<fully qualified domain name>:<ca port>/ca/admin/console/config/login?pin=<PIN>), on gets an error page from Tomcat. According to the exception, it cannot load a required class from Jakarta Commons Collections: java.lang.NoClassDefFoundError: org/apache/commons/collections/ExtendedProperties at org.apache.velocity.runtime.RuntimeInstance.<init>(RuntimeInstance.java:160) .... Version-Release number of selected component (if applicable): pki-ca-1.0.0-1.fc8 tomcat5-5.5.26-1jpp.2.fc8 How reproducible: Always Steps to Reproduce: 1. Install pki-ca (http://pki.fedoraproject.org/wiki/PKI_Install_Guide) 2. Try to visit the configuration URL that the RPM install script outputs on the terminal Actual results: An exception is thrown by Tomcat Expected results: The Certificate Authority Configuration Wizard page is displayed Additional info: The workaround is to symlink the jakarta-commons-collections library into Tomcat's lib dir, then restart pki-ca: ln -s /usr/share/java/jakarta-commons-collections.jar '/usr/share/tomcat5/common/lib/[commons-collections].jar' Possibly the more correct place would be /var/lib/pki-ca/webapps/ca/WEB-INF/lib instead of /usr/share/tomcat5/common/lib/, if Tomcat itself doesn't require jakarta-commons-collections.
