Tomcat Restart Error - BalancerFilter

Question

I am trying to setup an SSL for Tomcat and when I restart the service I get the following issues in the log:

... org.apache.catalina.core.StandardContext filterStart

SEVERE: Exception starting filter BalancerFilter

java.lang.NoClassDefFoundError: org/apache/tomcat/util/digester/Digester ...

This was working fine before the restart. Only localhost:8080 works but https://localhost:8443 doesn't. As far as I can tell this isn't an issue with the settings in tomcat/conf/server.xml.

Some leads have pointed me in the direction of downloading this digest plugin, but that doesn't make sense if this worked previous to the startup.

Your help is appreciated.

can you post the complete stacktrace - does it include a `ClassNotFound` exception — JoseK, Nov 11 '11 at 10:16

It seems to have been a misconfiguration in the Tomcat/conf/server.xml file causing the secure port to malfunction.

The SSL has been setup and starts correctly, yet still displays the bit about the Digest in the logs. I am not entirely sure as to what it pertains, but it seems to have no effect on the Tomcat instance, which now runs fine.
