Thank you for the info. That settles it for me.

Oops, meant unpackWars="false"

Tomcat does unpack war files before starting the context. That's
because of performance issues if it really tried to run the app from
an archive. Typically if unpackWars="true", tomcat will unpack to the
work directory instead of the webapps dir.

Thank you for your interest. The application starts very slowly
with the war and my classloader (this is a standard app, not
webapp). The war also has a webapp in it. This has nothing to do
with the application logic. It's the leading time to load the
classes. It takes about 2 or 3 minutes. The same JVM 1.5.0 runs
Tomcat (5.5.12) would response to request much quicker (about 10
seconds) after the 1st request. If I run the war file unpacked and
using standard classloader, it's a couple of seconds before things
run. However, using our own class loader with the packed war (which
searches all libraries in the lib and classes in the classes
directory) it takes along time described above.
My question is about how Tomcat does this in the unpacked war
scenario. I couldn't find the Tomcat loader that does this. I
suspect it unpacked it first, but this is a wild speculation.

maybe you could give a bit more context to interpret "very slow" or
"quickly".
like what version of tc and jvm are you using ... etc

Anyone have an idea about this?

We have a sizable war file (|unpacked|) that needs to be run in
certain way outside of Tomcat. To do this, we created a classloader
which works Ok except that it's very slow (using JarFile). I know
that when deploy apps in Tomcat, I can specify it to not to unpack
(|unpackWAR = "false"). However, Tomcat load and run the apps
quickly. I looked into Tomcat source, the org.apache.catalina.loader
package and could not find anything like that. I see
WebappClassLoader, but it seems to load from an unpacked war, not
packed war. Does Tomcat actually unpack the war before loading the
app? If not, could someone point me to the right place to look, or
give some advice on how to write this thing faster?
Thanks,
