Classloader question

[Juan Ignacio Garzón <ju...@gmail.com>]

Hi,
I'm working with Tomcat 4.1.

I have a library that has to be shared between all the applications,
but it has singletons that should have one instance per application.

In a normal situation, each application could have the .jar in it's
WEB-INF/lib directory, but there is a requirement saying that this is
not possible.

So, is there a way for making a .jar available to all the
applications, but using each application's class loader, so that
static fields are not shared between applications?

Thanks in advance!

No. You will have to put the JAR file into each webapp's WEB-INF/lib
directory.

You could write your own classloader, but that would be a real mess.
