Servlet registration in web.xml with weblogic 5.1 sp10

Question

I've been developing this site using one "dispatch"
          servlet as my traffic cop for my framework. i now
          have to do this charting thing and i plan to
          stream in an image from a servlet. this means adding
          another servlet to the application. i've edited the
          web.xml according to the standerd and WL still pukes
          on startup saying
          "Error parsing descriptor in Web application
          'c:/workspace/com/somthing/'
          org.xml.sax.SAXParseException: Element "web-app" does
          not allow "servlet" here."
          below is my web.xml file...
          <?xml version="1.0" encoding="ISO-8859-1"?>
          <!DOCTYPE web-app
          PUBLIC "-//Sun Microsystems, Inc.//DTD Web
          Application 2.2//EN"
          "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
          <web-app>
          <description>
          blah blah
          </description>
          <servlet>
          <servlet-name>
          WebDispatcher
          </servlet-name>
          <servlet-class>
          com.somthing.somthin.WebDispatcher
          </servlet-class>
          </servlet>
          <servlet-mapping>
          <servlet-name>
          WebDispatcher
          </servlet-name>
          <url-pattern>
          /dispatch
          </url-pattern>
          </servlet-mapping>
          <servlet>
          <servlet-name>
          AssetChartServlet
          </servlet-name>
          <servlet-class>
          com.something.somthn.charts.ChartServlet
          </servlet-class>
          </servlet>
          <servlet-mapping>
          <servlet-name>
          ChartServlet
          </servlet-name>
          <url-pattern>
          /Chart
          </url-pattern>
          </servlet-mapping>
          some jsp tags
          </web-app>
          What am I doing wrong? Do I have to register the
          servlet in the weblogic.properties file? If so do I add the line
          weblogic.httpd.register.chart=com.somthing.somthin.charts.ChartServlet
          And the the (local)url would be http://localhost:7001/Chart ? And if
          this is the case where/how do I do the url mapping bit for this?
          Any help would be greatly appreciated.
          thanks,
          -Gabe

To answer Mike's follow-up question, yes. From the DTD for the web.xml
          file:
          <!ELEMENT web-app (icon?, display-name?, description?, distributable?,
          context-param*, servlet*, servlet-mapping*, session-config?,
          mime-mapping*, welcome-file-list?, error-page*, taglib*,
          resource-ref*, security-constraint*, login-config?, security-role*,
          env-entry*, ejb-ref*)>
          The ordering of elements must be followed if they are specified in the DTD.
          Move your first <servlet-mapping> element to after the second <servlet>
          element and it should work just fine.
