It's possible. from http://java.sun.com/developer/technicalArticles/Servlets/servletapi2.3/ I found this: Class Loaders Here's a small change with a big impact: In API 2.3, a servlet container (a.k.a. the server) will ensure that classes in a Web application not be allowed to see the server's implementation classes. In other words, the class loaders should be kept separate. That doesn't sound like much, but it eliminates the possibility of a collision between Web application classes and server classes. That had become a serious problem because of XML parser conflicts. Each server needs an XML parser to parse web.xml files, and many Web applications these days also use an XML parser to handle reading, manipulation, and writing of XML data. If the parsers supported different DOM or SAX versions, that could cause an irreparable conflict. The separation of class scope solves this issue nicely. Which would indirectly support Jboss not being client, It's Serlvet 2.3 though... so maybe not. My understanding is that all web apps should have different class loaders. > > > ----- Original Message ----- > From: "Jim Barrows" <[EMAIL PROTECTED]> > To: "Struts Users Mailing List" <[EMAIL PROTECTED]> > Sent: Friday, August 20, 2004 12:54 PM > Subject: RE: Deploying Struts ??? > > > > > > -----Original Message----- > > From: Lykins Don H Contr AFSAC/ITS [mailto:[EMAIL PROTECTED] > > Sent: Friday, August 20, 2004 8:47 AM > > To: 'Struts Users Mailing List' > > Subject: RE: Deploying Struts ??? > > > > > > What are you referring to as a "classpath loader"?? > > Sorry.. class loader. > > > > > Won't this cause conflicts if each project has their own WAR > > with struts inside? > > Nope, not at all. > > > What happens if they use different versions of Struts in each > > WAR file? > > > Doesn't matter, since each war in essence has it's own class > loader, and > will load classes from the local war. > > If you really want to understand what's going on, I would > highly recommend > reading the J2EE spec yourself.
