Hi,
I am using Callisto with all features updated (yesterday).
I have read the article "Exception Handling with JAX-RPC" from Ping Wang
and Russell Butek and I believe that I am beginning to understand how I
should use wsdl:fault in my webservice.
Conform the instructions, I added the following lines to my wsdl:
<types>
..
<xsd:element name="PreFillResponseFault">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="compliance" type="xsd:string"></xsd:element>
<xsd:element name="bedrijfsObject" type="xsd:string"></xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</types>
<wsdl:message name="PreFillFaultMsg">
<wsdl:part name="fault" element="tns:PreFillResponseFault" />
</wsdl:message>
<wsdl:operation name="getPreFill">
<wsdl:input message="tns:getPreFillRequest"></wsdl:input>
<wsdl:output message="tns:getPreFillResponse"></wsdl:output>
<wsdl:fault name="fault" message="tns:PreFillFaultMsg"></wsdl:fault>
</wsdl:operation>
The WSDL-editor does not show any errors.
When I use the wizzard to generate the webservice, WTP generates
PreFillResponseFault as if it were a regular type. The class does not
extend java.lang.Exception.
I can add the necessary code manually but as soon as I try to test the
code with the webservices client, all the changes are overwritten.
Is it possible to use Callisto to build doc/literal webservices that use
wsdl:fault?

Hi,
Thanks a lot! I'm now at home but I know that I did not write a line
like that. I'll check monday and will tell you the result.
I really like working with Eclipse/Callisto and especially the WTP-tools
have helped me a lot to understand how to use webservices (my colleagues
who still have to work with Jdeveloper 10.1.2 are jealous :-) but I have
heared that 10.1.3 should be significantly better).
The tutorials on the Eclipse-WTP site are very instructive on how to
start writing webservices but I am certain that more information, like
the one you provided, would help a lot of people. Maybe that Kathy
and/or a colleague could write such a tutorial?
Have a nice weekend,
Ben

Hi,
I added the soap:fault line and it works!
Out production webserver is Oracle IAS and some time ago I asked why my
sample proxy application which ran without problems on my development
machine, would nor run on the Oracle server.
Once I found the solution, I know that it is pretty dumb but all I had
to do was copy the endpoint from the WSDL and use it in the
setEndpoint-method.
Sometimes it is this kind of simple information which can take a lot of
time to look for.
