Hi,
I'm a relative newcomer to Axis2 and this is my first encounter with
this list. I'm pretty sure this is a question you've had
time-and-again, although I've had no joy in the list archives - I
probably don't know the correct terminology to frame my question.
I am using Axis2 to support web-services. I define these through
WSDL/XSD and use wsdl2java to generate Java classes (ADBs?) for
request/response types, then write web-service code in Java to process
them. I'm trying to add some restrictions to my XSDs and have the
ADBs process them, but I'm not getting quite the behaviour I expect.
I've tried adding a couple of type restrictions to my web-services:
[1] A Yes/No type that is a string with an enumeration restriction;
[2] A star-rating type that is a number from 1-5 inclusive.
Here's the XSD snippet for the latter:
<xsd:simpleType name="Rating">
<xsd:restriction base="xsd:int">
<xsd:minInclusive value="1" />
<xsd:maxInclusive value="5" />
</xsd:restriction>
</xsd:simpleType>
Using soapUI I can test that my services work for correct values, and
indeed they do. However, when I enter a value that violates one of my
restrictions I get a simple axis fault message with the following:
<soapenv:Fault
<faultcode>soapenv:Server</faultcode>
<faultstring>unknown</faultstring>
</soapenv:Fault>
What I'd like to do is make the "unknown" part more meaningful in
light of these restrictions, similar to its behaviour if I omit a
required element:
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode
<faultstring>org.apache.axis2.databinding.ADBException:
Unexpected subelement thisIsRequired</faultstring>
</soapenv:Fault>
For instance, entering 6 for a star rating might give:
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode
<faultstring>WhateverException: 1 <= "rating" <= 6 violated:
found 6</faultstring>
</soapenv:Fault>
I realise I can configure axis2.xml to include stacktraces, but they
are of limited use because the exceptions generated for these
restrictions (IllegalArgumentException for YesNo; RuntimeException for
Rating) don't seem to have meaningful error messages.
Is it possible to improve these exception messages and/or the
faultstring messages for restrictions? (... without doing the
validation manually in Java)
Many thanks,
David
