As I said...I took a shotgun approach...meaning I took all JAR files out of
the individual folder and put it in the common classloader...I then moved
the MidTier.jar back into and that got Mid-Tier working....but I couldn't
config it....I moved the Config.jar file back into the individual folders,
and everything worked fine from my limited testing perspective...so this
list is 'everything else'
first thing I did was edited conf/catalina.properties and changed line 32
from
common.loader=${catalina.home}/common/classes,${catalina.home}/common/i18n/*
.jar,${catalina.home}/common/endorsed/*.jar,${catalina.home}/common/lib/*.ja
r
to
common.loader=${catalina.home}/common/classes,${catalina.home}/common/i18n/*
.jar,${catalina.home}/common/endorsed/*.jar,${catalina.home}/common/lib/*.ja
r,${catalina.home}/common/arsystem/*.jar
I then created the arsystem folder under /common
I did this so that I was keeping my common libraries separate from Tomcats
common ones...:)...here is a list of the jar files in the common/arsystem
folder
arapi71.jar
arcmn71.jar
ARInterfaces70.jar
arrpc71.jar
arutil71.jar
axis.jar
blowfishj.jar
commons-beanutils.jar
commons-codec-1.3.jar
commons-collections-3.2.jar
commons-configuration-1.3.jar
commons-digester-1.7.jar
commons-discovery-0.2.jar
commons-lang-2.2.jar
commons-logging-1.1.jar
cos.jar
ehcache-1.2.4.jar
GraphPlugin.jar
icu4j.jar
jaxrpc.jar
log4j-1.2.14.jar
Logger.jar
oncrpc.jar
ReportCommon.jar
saaj.jar
spring.jar
Support.jar
websvc71.jar
wsdl4j-1.5.1.jar
Both of the web mid-tiers I was using for this testing were 7.1 Patch 4. I
haven't moved this to our Dev server yet....but if I come up with a more
refined list...I'll post to this thread

Sweet. Would you mind posting the list of jars to the list that you moved
to a common classloader?
Thanks,
