From OpenNMS

Just a note for anyone with slackware 10.2 and the apache/php/tomcat packages from http://www.linuxpackages.net

be advised that the jakarta regexp jar is missing from the tomcat dist you'll need to download it here http://jakarta.apache.org/site/downloads/downloads_regexp.cgi and install the jar into catalina_home/common/endorsed/

and you'll also need to copy the xercesImpl.jar from the /opennms-1.2.8-1/source/devlib/ to catalina_home/common/endorsed/

tomcat 5.5

Running tomcat 5.5 (from http://tomcat.apache.org/) and jdk1.5.0_05 I needed to add the following to $TOMCAT_HOME/common/endorsed to get the webapp to start:

• xalan231.jar
• xercesImpl.jar
• xmlParserAPIs.jar

You could also use these files from the mavenized OpenNMS build:

• xalan-2.4.1.jar
• xercesImpl-2.6.2.jar
• xml-apis-1.0.b2.jar
