I won't repeat what everyone else has said -- because that's all great
advice -- but also consider this: change your build/deployment processes
such that each app gets its own, separate copy of the needed JARs.

I think you should evaluate how your app is designed. If you need to
communicate cross context/processes you should consider using something like
JMS to give you good isolation. Today you may want to have everything on a
single box, tomorrow you might want other servers.

Another option to consider is to change the need for a singleton type of
class or store some info in a database.

RE: context sharing problems

2004-09-30 Thread Shapira, Yoav

Hi,
Then put the singleton in the shared repository, not in ROOT.

In general, what you're trying to do is inadvisable and against the
spirit of the Servlet Specification: web applications are supposed to be
self-contained.  Features like a shared classloader repository are not
mandated by the Spec and are a convenience-type feature with different
levels of support and portability across containers.  Consider
alternative approaches to inter-webapp communication, such as over the
network, via shared storage (filesystem or DB), or via a messaging
platform such as JMS.

RE: context sharing problems

Well, I could do (and this actually works) but the problem then is that the
web-apps are actually started up separately (in separate memory spaces) and
the 'admin' one cannot access the singleton in the 'ROOT' one that has been
initialised with some values..

I need some sort of context settings that point the classpath  (vm ??) to
the same place

Any ideas??

context sharing problems

2004-09-30 Thread Michael Cornell

Hi,

I am trying to share the same class files (and libraries) between two
different web-apps one running in ROOT/ and one is admin/

Basically, I want the first one to run from the default context ie
http://www.x.com/
And the second web-app to run as http://www.x.com/admin

However, all of the classes for both web-apps are situated in the first one
(ROOT).

This may seem a strange way of doing things, but I need to reflect the
changes made in admin (basically a collection of  jsps etc) in ROOT (a
series of filters etc).  I have actually got this to work using a tomcat
plugin in eclipse because of the way eclipse shares libraries and classpaths

Does anyone know how I could do this for a standalone tomcat (running in
windows)???

Just to clarify:

Web-apps\
ROOT\
WEB-INF\
Classes\

My\package\name\MyFilter.class

My\package\name\StrutsAction.class

My\package\name\ApplicationResources.properties

My\package\name\MySingletonIIWantTochangeViaTheGuiRealTime.class
Admin\
WEB-INF\
Web\index.jsp







Thanks for your help
M
