jboss 4.2.3

I am having the exact same problem with jboss as the other person in the MacOS forum. I get this when I run jboss (with java 6)

jboss/bin/./run.sh: line 89: ulimit: open files: cannot modify limit: Invalid argument
run.sh: Could not set maximum file descriptor limit: unlimited
=========================================================================

JBoss Bootstrap Environment

JBOSS_HOME: /Users/Troy/jboss

JAVA: java

JAVA_OPTS: -Dprogram.name=run.sh -Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000

CLASSPATH: /Users/Troy/jboss/bin/run.jar

=========================================================================

jboss starts, but I cannot view the page I built (and which works perfect on a windows computer). When I type in http:localhost:8080/hello I get this:

HTTP Status 404 - /hello

type Status report

message /hello

description The requested resource (/hello) is not available.
JBossWeb/2.0.1.GA

I've looked everywhere on jboss.org and cannot find the answer to this apparently simply question.
Thank you
