I'm using JRun 3.0 SP2 on WinNT 4 with the 8/14 nightly build of Struts.
With all of the commons-*.jar and struts.jar in WEB-INF/lib, I get a stack trace showing ClassNotFoundException for ActionFormBean when JRun attempts to load-on-startup the ActionServlet.
If I remove the load-on-startup from my web.xml I stop getting the ClassNotFoundException but get that org.apache.struts.action.MESSAGE couldn't be found error.
As a workaround I've included all the struts jars and my WEB-INF/classes directory in the server classpath and it seems to work fine but I'm pretty sure that I can't hot deploy anymore.
From the stack trace I see ActionServlet call Digester which calls down through JAXP and Xerces until it gets to Digester.startElement and throws the ClassNotFoundException. I'm wondering if Xerces is loading funny or somehow it's Xerces classloader thats being used to search for ActionFormBean instead of my web app's classloader... I have to put xerces and xalan first in my server classpath so it gets used when I use JAXP. But it seems like my application should work as long as the Struts classes are loaded in my web apps classloader because (as I understand it) child classloaders will ask their parent if they have a class but a parent wont ask a child.
I included my stack trace below:
