Hi Mike,

Someone has posted a solution to the new error you're getting:

http://mail-archives.apache.org/mod_mbox/tomcat-users/200512.mbox/[EMAIL PROTECTED]

their solution was under:

6. Edited Tomcat 'server.xml' (in the 'conf' folder).  Removed the line:
  <Listener className="org.apache.catalina.core.AprLifecycleListener" />

This solution won't solve the problem below.

This only disables APR usage. Using APR is an improvement in most cases, as it permits Tomcat to take advantage of native library code.

OK, I just reinstalled Tomcat 5.5.23 to resolve an issue with Tomcat starting up. Now I have an issue with my listener not starting up. The class in question LifecycleListener exists in the %CATALINA_HOME%\server\lib\catalina.jar file. Do I need to set a switch or something when calling startup.bat or setting something else to use listeners? Why would it have an issue loading/finding catalina.jar? There are no other error messages in my log file.

Where is the jar with com.sf.listener.SingletonLoader?


What function does it perform in your web application?


p

If it's not in server/lib (with catalina.jar) it won't share the right classloader, and thus is unable to 'see' the interface class.
