[news.eclipse.newcomer] Re: AprLifecycleListener not initializing in Tom

[Larry Isaacs <Larry.Isaacs@xxxxxxx>]

I'm not sure this one covered by the FAQ because it is normal Tomcat 
behavior.  It occurs outside of Eclipse as well.

The message can be ignored if you aren't trying to use APR (Apache 
Portable Runtime).  Use of APR is enabled by default in server.xml by 
the inclusion of the AprLifecycleListener.  If this listener finds the 
APR library, plus a couple of other things, use of APR occurs, i.e. 
connectors use APR instead of Java equivalents to do the work.  If the 
APR library isn't found, this fact is logged to inform you that APR 
isn't being used.  Note that the message is just information, i.e. INFO. 
 It doesn't qualify as an error or warning.

For APR info, see: http://tomcat.apache.org/tomcat-6.0-doc/apr.html

Cheers,
Larry
