<div class="jive-rendered-content"><p>It appears that this problem was caused by the use of the "jsp" servlet-name which I was using for testing purposes. Most likely, the "jsp" servlet-name was already reserved by the container. After I changed it to something other than "jsp," everything worked as expected.</p><pre class="jive-pre"><code class="jive-code jive-xml">    <span class="jive-xml-tag"><servlet></span>

</code></pre><p style="margin-top: 1em;">It was a little bit surprising that this worked on Tomcat though, since my understanding was that JBoss was built on Catalina. After testing it on geronimo-tomcat7-javaee6-3.0-M1, it failed with the same error, though, so there must be something different with Tomcat. Fortunately, deploying to geronimo-jetty7-javaee5-2.2.1 gave me a much more useful exception message "<tt>org.apache.geronimo.common.DeploymentException: jsp servlet already present</tt>" that lead me to test the use of a different servlet-name.</p></div>
