hi, I configured a virtual directory on the JBoss Web Server of JBOSS 5.0, the D:\jboss-5.0.0.GA\server\xinosofterp\deploy\jbossweb.sar\server.xml content is

<Server>

 <!-- Optional listener which ensures correct init and shutdown of APR,
 and provides information if it is not installed -->
 <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
 <!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
 <Listener className="org.apache.catalina.core.JasperListener" />

 <Service name="jboss.web">

 <!-- A HTTP/1.1 Connector on port 8080 -->
 <Connector protocol="HTTP/1.1" port="8080" address="${jboss.bind.address}"
 connectionTimeout="20000" redirectPort="8443" />

 <!-- Add this option to the connector to avoid problems with
 .NET clients that don't implement HTTP/1.1 correctly
 restrictedUserAgents="^.*MS Web Services Client Protocol 1.1.4322.*$"
 -->

 <!-- A AJP 1.3 Connector on port 8009 -->
 <Connector protocol="AJP/1.3" port="8009" address="${jboss.bind.address}"
 redirectPort="8443" />


 <Engine name="jboss.web" defaultHost="localhost">

 <Realm className="org.jboss.web.tomcat.security.JBossWebRealm"
 certificatePrincipal="org.jboss.security.auth.certs.SubjectDNMapping"
 allRolesMode="authOnly"
 />


 <Host name="localhost">

 <Valve className="org.jboss.web.tomcat.service.jca.CachedConnectionValve"
 cachedConnectionManagerObjectName="jboss.jca:service=CachedConnectionManager"
 transactionManagerObjectName="jboss:service=TransactionManager" />

 <Context path="/upload" docBase="d:/home/upload" debug="false" reloadable="true" override="true" crossContext="true" />

 </Host>

 </Engine>

 </Service>

</Server>

I got the following error when i started the jboss 5.0
