WSDL2Java java.io.IOException Type ... is referenced but not defined

[ja...@accenture.com]

I am having trouble generating a set of Java classes from an existing WSDL file that was originally generated for use in WebLogic Server 6.1. We are looking to duplicate the Web Service functionality in Axis/Tomcat. The WSDL and the generated SOAP messages must remain the same. It's the Java app that must work around this requirement. When I run the WSDL2Java app, I receive the following exception:
 
#>java -cp %AXISCLASSPATH%;. org.apache.axis.wsdl.WSDL2Java MeterEvent.wsdl
java.io.IOException: Type {java:com.dsn.centralizedmeter.domain}MeterEvent is referenced but not defined.

This is the WSDL file I am using:

com.dsn.centralizedmeter.domain.MeterEvent is a Java class that maps to the MeterEvent complexType from the WSDL. If I change
    <message name="sendRequest">
      <part name="message" type="domain:MeterEvent" /> 
    </message>
to
    <message name="sendRequest">
      <part name="message" type="xsd:String" /> 
    </message>
to remove the reference to the complexType, WSDL2Java works without problems.
 
Can anyone tell me what I am missing or doing wrong in this scenario? I have found very little documentation regarding using custom Java classes as SOAP message types.
 
Thanks for your help.
