All,
I'm trying to get a webapp that has been running under TC 5.5 for
quite a while running under Tomcat 7.0. Everything is the same except
for my new server.xml:
<?xml version='1.0' encoding='utf-8'?>
<Server port="8066" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.core.AprLifecycleListener"
SSLEngine="on" />
<Listener className="org.apache.catalina.core.JasperListener" />
<Listener

<Listener
className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<Listener

<GlobalNamingResources>
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
</GlobalNamingResources>
<Service name="Catalina">
<Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
maxThreads="150" minSpareThreads="25"/>
<Connector port="8065"
redirectPort="443"
protocol="org.apache.coyote.ajp.AjpNioProtocol"
URIEncoding="UTF-8" executor="tomcatThreadPool" />
<!-- You should set jvmRoute to support load-balancing via AJP ie :
<Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm1">
-->
<Engine name="Catalina" defaultHost="localhost">
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
</Host>
</Engine>
</Service>
</Server>
I get this in my catalina.out when I try to start (apologies for the
poor line-wrapping):

I suspect the problem is that my webapp uses log4j but does not
include commons-logging. I'm guessing that log4j has some components
that depend upon commons-logging even though I don't use those components.
It seems clear to me that there are two ways to fix this:
1. Add commons-logging to my webapp's WEB-INF/lib directory
2. Configure Tomcat not to scan log4j.jar
I'm wondering if Tomcat should tolerate ClassNotFoundExceptions while
JAR-scanning... otherwise, a webapp that wants to use a library will
have to make sure *all* dependencies are installed alongside and not
just those that are actually required at runtime.
Thanks,
- -chris
