If it helps at all I am running on Windows XP.

If it's in the webapp directory, that explains it.
It's not in the same classloader.



Lifecycle is server related as opposed to application.

You'll need to add a <listener> attribute to your web.xml to make it work.


p

You probably want ServletContextListener, rather than a LifecycleListener. The latter is a Tomcat interface, rather than a Servlet spec definition - which would be more useful to you.

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:

This solution won't solve the problem below.

  This just produced an additional error in the catalina log file:

SEVERE: Error listenerStart
Apr 23, 2007 9:39:50 AM org.apache.catalina.core.StandardContext start
SEVERE: Context [/fs] startup failed due to previous errors

This only disables APR usage. Using APR is an improvement in most cases, as it permits Tomcat to take advantage of native library code. Apr 23, 2007 9:39:50 AM org.apache.catalina.core.StandardContext start

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?

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. This is not an additional jar file. It is a class in my webapp directory. It's purpose is to load all the singletons for my application at application startup. So that there is no visible delay at code execution time while data is loaded from the database.
