Yes, except that shared is under CATALINA_BASE, not CATALINA_HOME. Since _HOME and _BASE are the same in most installations, I can't keep them straight without re-reading the RUNNING.txt file. Note that in Tomcat 6, by default, the shared directory disappears (as does server), and common is renamed to lib. The TC6 RUNNING.txt file indicates that lib should be under CATALINA_BASE, but the catalina.properties file defines the class loader for it as using CATALINA_HOME, so watch out for the discrepancy there. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Deploying shared .jar's
From what I've read in the Tomcat 5.5 docs, I should be able to deploy a .jar that is shared across multiple webapps on Windows by putting it in the (tomcat)/shared/lib folder, but I've never gotten that to work. I've always had to put that jar in the web-inf/lib folder of each of the webapps that need it, in order for them to be able to use it. Why is that? Is there something I'm missing about deploying shared jars? The wasted disk space doesn't matter, but the hassle of putting the same .jar file in multiple different places does... Any help or explanations would be appreciated!

hi, By http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html Shared is the parent classloader of webapp. AFAIK the consequence of this in that a class loaded from webapp classloader can see other classes (whenever they come from shared, webapp or common), but the reverse is not true, and could lead to ClassNotDef or ClassNotFound exeption unless some classloader hack are performed ...

Check your conf/catalina.properties file and make sure this line is
present:
shared.loader=${catalina.base}/shared/classes,${catalina.base}/shared/li
b/*.jar
If the line is there (and not commented out), is there possibly an
access permissions problem with the jars you're putting into shared/lib,
especially if running as a service? You might also try turning on
-verbose:class and see what's being loaded from where.

It's there, but it got me to looking at some other stuff, and I think I
now know what's going on. Can you please tell me if this makes sense:
I have 3 different apps on one machine, each running in its own tomcat
instance using the catalina_base env var. The catalina_base locations
are all outside of catalina_home. What I was hoping was that I could
put my shared jars in catalina_home, but after re-reading the
description of cataline_base (again), it appears that I can't put shared
classes in catalina_home if I'm using the apps from catalina_base.
What I have is this:
Catalina_home =
e:\program files\Apacha\Tomcat5\all the sub-dirs
Catalina_base(s) =
e:\tomcatclients\webapp1
\conf
\webapps
etc
e:\tomcatclients\webapp2
\conf
\webapps
etc
etc.
With the way I read it now, anything I try to put under
catalina_home/shared/lib won't be visible to the webapps in the various
catalina_base folders. Is this correct? If so, it explains my trouble.
If not, then I've got to dig even deeper.
Thanks!

Hi Dave,
I believe one of the primary reasons that the
conf/catalina.properties file exists is so things like this are
configurable. If:
shared.loader=${catalina.base}/shared/classes,${catalina.base}/shared/lib/*.jar
doesn't do what you want, change it to:
shared.loader=${catalina.home}/shared/classes,${catalina.home}/shared/lib/*.jar
or something else that achieves your goal.
D'oh Why didn't I think of that???
Cheers,
Larry

Yes. Look at RUNNING.txt in your Tomcat installation directory. To
quote from it:
When you use this -Dcatalina.base=$CATALINA_BASE argument, Tomcat
will calculate all relative references for files in the following
directories based on the value of $CATALINA_BASE instead of

* shared - For classes and resources that must be shared

* webapps - Automatically loaded web applications
* work - Temporary working directories for web applications
* temp - Directory used by the JVM for temporary files
(java.io.tmpdir)
Note the inclusion of shared in the CATALINA_BASE set. It would be
better if it read For classes and resources that must be
shared across
all web applications within this Tomcat instance.
Yes, that's what I decided on re-reading it for the umpteenth

of clarification by the doc writers might be in order.
