Hi Gregg,
I have had a similar problem.
I have use wsdl2Java with the following options
--serverSide = true
--skeletonDeploy = false
to generate operations tags and I have copied them in my original wsdd file.
You can also use server-side stubs. (with server-side stubs : no need of
opreations tags)

list last week which deals around this subjet.

Subject : Problem with exceptions and inherited fields (from Throwable)
Date : 12-12-2005
Hello,
I am new with Axis and I think is a very good framework but the
documentation isn't very verbose.
I have a question : how to stop inheritance search in bean serialization
(do not serialize ancestor's public fields) ?
Is there an sample of this feature somewhere ?
I have found a solution but I'm not completely satisfied with it.
I am writing a Web Service connector for an existing Java application
with the literal/wrapped mode.
My connector exception extends the java.rmi.RemoteException one
(according to the user's help advice) and I had registered a bean
mapping for it.
It works well but Axis always includes the "cause" field inherited from
java.lang.Throwable in the SOAP message (I suppose it does this due to
the getCause and initCause methods of this class).
I don't want this field to be in the message because my connector must
be interoperable and the "cause" field may have no equivalent in non
Java frameworks.
I haven't found in the documentation how to indicate to Axis that it
should not serialize this field.
When I use the java2wsdl tool, it always produces the following warning
message :
"- Please register a typemapping/beanmapping for
'services.myPackage.MyFault' " (I tried to define mapping set but it
produced no change)
I do this in the .wsdd deploying file :
<beanMapping xmlns:ns1="http://myPackage.services"; qname="ns1:MyFault"
languageSpecificType="java:services.myPackage.MyFault" />
but when I call the Axis online wsdl generator I can read the following
warning message in the tomcat console :
"- The class java.lang.Throwable is defined in a java or javax package
and cannot be converted into an xml schema type. An xml schema anyType
will be used to define this class in the wsdl file."
I also tried the --stopClasses java2wdsl option without success.
Finally, I have investigated a bit further in the Axis source code (to
understand how it really works) and I found 2 way of doing this.
1 - To edit by hand the wsdl file and remove the following lines :
<import namespace="http://lang.java";>
...
<element name="cause" nillable="true" type="xsd:anyType"/>
and then generate (from this cleaned wsdl) server-side stubs and use
them in the server code.
2 - To include metadata pieces of code in Exception classes to precise
the serialization of the cause field.
Secify it as an attribute (and it will not be serialized) or specify it
as optional ( minOccurs="true") and ensure it will be always null by
overriding the "getCause" method.
Example :
public class MyFault extends RemoteException implements Serializable
{
...
/**
* Overriden for smart serialization : use the retrieveCause() method
instead.
* @return always null
* @see #retrieveCause()
*/
public Throwable getCause() {
return null; // do not serialize the value of this field
(inherited from java.lang.Throwable)
}
/**
* Implements the original getCause beahvior.
* @see #getCause
*/
public Throwable retrieveCause() {
return super.getCause();
}
//-- Type metadata for Axis
private static org.apache.axis.description.TypeDesc typeDesc = new
org.apache.axis.description.TypeDesc(MyFault.class, false);
static {
typeDesc.setXmlType(new
javax.xml.namespace.QName("http://myPackage.services";, "MyFault"));
org.apache.axis.description.ElementDesc elemField = new
org.apache.axis.description.ElementDesc();
elemField.setFieldName("cause");
elemField.setXmlName(new
javax.xml.namespace.QName("http://myPackage.services";, "cause"));
elemField.setXmlType(new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema";, "anyType"));
elemField.setMinOccurs(0); // if null do not serialize this field
elemField.setNillable(true);
typeDesc.addFieldDesc(elemField); }
/**
* Return type metadata object
*/
public static org.apache.axis.description.TypeDesc getTypeDesc() {
return typeDesc;
}
}//-- End of class : MyFault ------
I have rejected the 1st solution because I dont want (for many reasons)
to include hundred lines of autogenerated code in my server.
Currently, I am using the second solution, but I think it is a bit triky.
Is there a better way to do this ?

Hi All:
Is there a way to make the wsdl2Java tool generate the operation tag
within the generated deploy.wsdd file? I'm having trouble serializing
defined faults. The User documentation appears to say that I need to
manually add the operation tag to the wsdd if I want faults to be
serialized properly. Is this true? Why isn't it enough to defined
in the wsdl? Does someone have a simple, but complete example of the
steps to get this working properly? Thanks for any feedback!
