AxisFault and auto generated wsdl problems
Well good people of the list,
Here are a couple of interesting problems for you to mull over and maybe help
me out with.
1. I have a problem with Axis regarding the WSDL returned from a service as
generated by Axis i.e when the ?wsdl option is specified.
The auto generated wsdl is not usable with the wsdl2java tool, I get the
following error from my ant task:-
wsdl2java:

BUILD FAILED
There is no indication as to where this error is happening within the wsdl
being processed......
When I look at the wsdl that was generated it contains the following complex
type definition:-
<complexType name="SystemFailureException">
<complexContent>
<extension base="">
<sequence>
<element name="sourceException" nillable="true" type="tns2:Throwable" />
</sequence>
</extension>
</complexContent>
</complexType>
It contains an element type tns2:Throwable, but NO tns2: name space has been
created in the wsdl at all. I also defined the sourceException as an
xsd:anyType in my hand coded wsdl used to originally generate the service. Also
notice that it has an undefined <extention base=>...</extention> element.
Another Exception I defined in exactly the same way in my hand coded wsdl
defines the sourceException correctly as an xsd:anyType as shown below:-
<complexType name="ApplicationException">
<sequence>
<element name="message" nillable="true" type="xsd:string" />
<element name="sourceException" nillable="true" type="xsd:anyType" />
</sequence>
</complexType>
What is causing Axis to not generate the namespace and to return two diffent
deinitions of Exception?
2. And now the strangest thing of all. My service returns many custom
exceptions from its methods. My auto created Junit test (modified by hand) is
used as a test client for the service. In some circumstances I get the
following AxisFault :-
AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: org.xml.sax.SAXException: Invalid element in
de.viaginterkom.ca.ecrm.eselfcare.common.exception.OrderFailedException -
description
faultActor:
faultNode:
faultDetail:
{http://xml.apache.org/axis/}stackTrace: org.xml.sax.SAXException:
Invalid element in
de.viaginterkom.ca.ecrm.eselfcare.common.exception.OrderFailedException -
description
at org.apache.axis.encoding.ser.BeanDeserializer.onStartChild
(BeanDeserializer.java:260)
at org.apache.axis.encoding.DeserializationContextImpl.startElement
(DeserializationContextImpl.java:963)
...
etc etc...
This implies it is trying to deserialize a custom exception defined by me as
OrderFailedException and the bean deserializer has found a property called
description this it knows nothing about. My custom exception does not define
description as a property and neither does the exception that it extends. It is
also NOT the exception that was thrown from the implementation. On closer
inspection using tcpmon the soap:fault returned, that Axis then converts to an
AxisFault is as follows:-
HTTP/1.1 500 Internal Server Error
Content-Type: text/xml; charset=utf-8
Date: Thu, 18 Mar 2004 08:23:47 GMT
Server: Apache Coyote/1.0
Connection: close
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>de.viaginterkom.ca.ecrm.eselfcare.common.exception.UnknownIDExcepti
on</faultstring>
<detail>
<ns2:fault xsi:type="ns1:UnknownIDException"
xmlns:ns1="http://exception.common.eselfcare.ecrm.ca.viaginterkom.de"
xmlns:ns2="urn:ESelfcareSoap">
<ns2:description xsi:type="xsd:string">msisdn</ns2:description>
<ns2:message xsi:type="xsd:string" xsi:nil="true"/>
<ns2:sourceException xsi:nil="true"/>
<ns2:type xsi:type="xsd:int">1</ns2:type>
</ns2:fault>
</detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
As you can see from this soap:fault the exception thrown by the service is NOT
an OrderFailedException but an UnknownIDException which is the correct
exception thrown by the implementation and it does have a property called
description. OrderFailedException is one of the exceptions defined in the
throws clause of the implementation.
I have this problem in more than one client call but in general both the
AxisFault and the soap:fault agree on the custom exception returned by the
implementation.
So why does the Axis code try to deserialize the wrong exception in a few cases?
If anybody has answers to either of these issues please let me know. This issue
is serious as we have a deadline for this service to go into QA by COB Monday
and I do not want to have to use another SOAP service such as GLUE to get over
these issues.

Re: AxisFault and auto generated wsdl problems
Posted by sm...@spansurf.com.
Hi Patrick
None of my custom Exceptions extend java.rmi.RemoteException or implement
Serializable.
My base exceptions extend only java.lang.Exception and all other custom
exceptions extend these base exceptions. The mappings in the WSDL I created for
them are correct and so is the definition in the wsdd for the <typeMapping>
i.e.
<typeMapping
xmlns:ns="http://exception.common.eselfcare.ecrm.ca.viaginterkom.de"
qname="ns:OrderFailedException"
type="java:de.viaginterkom.ca.ecrm.eselfcare.common.exception.OrderFailedExcepti
on"
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
So your suggestions do not apply here.
Thanx anyway
Regards
Steve

Re: AxisFault and auto generated wsdl problems
Posted by "BLIS Webmaster (Patrick Houbaux)" <we...@blis-project.org>.
Hi Steve,
A quick tip that I found out to work when dealing with custom exceptions (since I was enable to use a custom exception based on the Axis sample).
The tip is: "Do not extend java.rmi.RemoteException and don't implement java.io.Serializable for a custom exception, but simply extend java.lang.Exception instead, and provide the corresponding Typemapping in the wsdd for deploying your service."
For instance:
package com.domain.myservice.rpc.fault;
public class MyCustomBaseException extends Exception { //extends RemoteException implements java.io.Serializable{
private java.lang.String info;
private java.lang.String message;
public MyCustomBaseException () {
}
public MyCustomBaseException (java.lang.String info) {
this.info = info;
}
public java.lang.String getInfo() {
return info;
}
public void setInfo(java.lang.String info) {
this.info = info;
}
public void setMessage(java.lang.String message){
this.message = message;
}
public java.lang.String getMessage(){
return message;
}
public String toString(){
return this.getInfo() + " " + this.getMessage();
}
}
Then you may extend any other custom exception you need from this one.
The type mapping in the wsdd looks like:
<typeMapping
xmlns:MyNS="urn:foo.domain.com"
qname="MyNS:BaseCustomFault"
type="java:com.domain.myservice.rpc.fault.MyCustomBaseException "
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
Hope it helps ... at least it should solve all your problems, at least for me it did the trick :)
Cheers,
Patrick.
