I typically like to deploy my dependencies (jars) to the endorsed directory of Tomcat so as to reduce the size of deployed project wars.

However, because the zkspring jars wire in their own listeners, via metainfo/zk/config.xml, this creates a problem. Specifically, non-Spring projects still try to wire up the Spring CoreWebAppInit, SecurityWebAppInit and WebflowWebAppInit listeners.

Since I am not declaring any listeners in my project's web.xml or zk.xml, I can only assume that it is inferring that my non-Sprng project must wire up the Spring listeners because they are declared at the zkspring jar level.

This basically is forcing me to remove the zkspring jars from the container's endorsed directory and deploy them with each and ever Spring project.

I believe the listeners should be wired exclusively at the project level within its web.xml file. This makes it so we can deploy frequently commonly used jars to the container without having to bloat the size of each war deployed.

The error I get at when trying to deploy a non-Spring project to Tomcat, which has the zkspring jars, is:
