1. AprLifecycleListener is a LifecycleListener.
That is, you must add it to a server and it will react on lifecycle
events coming from it.
2. Tomcat-Native is a native library. There are JRE limitations
associated with that:
One of them is that such library must be loaded exactly once. You
cannot load it twice. You cannot load it from two different class
loaders.
This issue usually comes up with JDBC drivers that have native components.
In the FAQ:
http://wiki.apache.org/tomcat/HowTo#I.27m_encountering_classloader_problems_when_using_JNI_under_Tomcat
3. If you want to debug Tomcat, some tips are in the FAQ.
http://wiki.apache.org/tomcat/FAQ/Developing#Debugging
4.
> my problem is that this class seems to not recognize apr in my computer.
The actual error messages =?
5. Do you need Tomcat-Native library at all? Tomcat runs fine without it.
