I am developing a web application I used to work with Tomcat 5.5. Recently I tried to upgrade to Tomcat 6 and during startup following error msg appears:

NFO: Starting Servlet Engine: Apache Tomcat/6.0.20
29.06.2010 14:44:52 org.apache.tomcat.util.digester.Digester startElement
SCHWERWIEGEND: Begin event threw error

at org.apache.tomcat.util.digester.Rule.begin(Rule.java:153)

Any clue what the reason for this could be?

Thanks in advance

That class should be in catalina.jar - I would guess either:

1. your installation got trashed somehow and you will have to wipe and try again
2. Some sort of classpath/environment problem is preventing finding the right jar? seems unlikely

I agree. Here's the link: http://aspose.com/file-tools
