Michele,
It looks like all of the jar files you mention can safely be deployed in
Tomcat's common lib area.
I'm not sure that's true of commons-logging or log4j.
Someone else might have a better memory than me, but I've a feeling that
they hold onto classloader references, which may cause a memory leak
during redeployments.

Another question, though, to ask yourself and your developers is, do you
really need 100 individual web apps to support the web services you
have?
In other words, there is no requirement to have a 1 to 1 correlation
between applications and web services.

Subject: Re: webapps question
Thanx 4 you answer;
ps: there are 100 webservices, not webapps
Pls, help me: I'm not a developer ... and I don't understand the
disadvantages of "static classes/fields loaded from common classloader
will
be shared among all webapps", Could you be a little more specific about
the
disadvantages?
Your suggestion is to "split" the apps into vitualhost like, context.xml
ecc..?
I use the oracle odbc thin; which problem should I have putting the jdbc
driver int the commos/lib ?
For reference, those are the jars userd in all webservices:
classes12.jar
ibatis-common-2.jar ibatis-dao-2.jar ibatis-sqlmap-2.jar activation.jar
axis-ant.jar axis.jar commons-discovery-0.2.jar
commons-logging-1.0.4.jar
jaxrpc.jar LEGO_CONDIVISI.jar log4j-1.2.8.jar mail.jar saaj.jar
wsdl4j-1.5.1.jar xmlsec-1.4.0.jar

I've 100 webapps on one single tomcat instance.
Every webapps has in his WEB-INF/lib the same jars
I've some permgen memory problems too
Moving all the shared libs in tomcat's root/common/lib should help me
reducing the perm gen memory usage?
Should it be a good pratics
It will solve one problem, but will cause others, difficult to trace.
E.g.
static classes/fields loaded from common classloader will be shared
among
all webapps.
You should rather refactor your webapp to be able to change its 'work
context' depending on URI/domain name.
