Sean, unfortunately, there are issues when packaging an application as an EAR vs WAR. I agree that if you only have JSP and Servlets and WEB components in general (ie only stuff that goes into a WAR), then you're OK with WEB-INF/lib.
BUT if you deploy your Struts app as part of a EAR, that may not work (it didn't for me and I wasted a few hours trying to understand why that @^%@$#@% app server couldn't find my struts.jar). Check out http://www.onjava.com/pub/a/onjava/2001/06/26/ejb.html It's the type of thing that can ruin an evening... :) Andrej PS. I agree with your sentence "EJB should not care about Struts". The problem is that if the app uses a single Class Loader and it's the EJB's, then the app must have a link to the "utility JARs". > -----Original Message----- > From: Sean Owen [mailto:[EMAIL PROTECTED]] > Sent: Friday, December 14, 2001 12:49 PM > To: Struts Users Mailing List > Cc: [EMAIL PROTECTED] > Subject: Re: Weblogic problem... > > > Adding struts.jar to the WEB-INF/lib directory within your > web application > is the right way to make it available to your servlets and > JSPs, regardless > of whether you deploy in an exploded directory format, as a > .war, or as an > .ear with a web app component. > > It's not then visible to the EJBs, since the EJB classloader > is a parent of > the web classloader, but that shouldn't matter - EJBs don't have any > business using Struts classes, right? > > Sean > > > ----- Original Message ----- > From: "Sobkowski, Andrej" <[EMAIL PROTECTED]> > To: "'Struts Users Mailing List'" <[EMAIL PROTECTED]> > Sent: Friday, December 14, 2001 4:40 PM > Subject: RE: Weblogic problem... > > > > Small addition to my previous message (sorry, I responded > without reading > > with too much attention): > > - if yours is a *.war archive only, then adding struts.jar to your > > WEB-INF/lib directory should work.
