Description

I wrote a WSDL, ran wsdl2java.bat to generate server side code. Compiled. Build the aar and deployed it in tomcat.

I then sent it a couple sample soap files and got unexpected results. This makes me think that some of the xsd features I used are not supported by Axis, namely the abstract attribute and inheiritance of complex types. Can someone confirm my suspicions or tell me where I'm going wrong?

The first message I sent was:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:m0="http://consumermgr.sss.com/consumermgr">
<SOAP-ENV:Body>
<m:addDevice xmlns:m="http://consumermgr.sss.com" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<addDeviceInputParam>
<m0:header>
<m0:timestamp>2001-12-17T09:30:47.0Z</m0:timestamp>
<m0:fromId>0</m0:fromId>
</m0:header>
<m0:deviceId>
<m0:idType/>
<m0:id/>
</m0:deviceId>
<m0:attributes></m0:attributes>/>
</addDeviceInputParam>
</m:addDevice>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The response I got was:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Client</faultcode>
<faultstring>Please implement com.sss.consumermgr.consumermgr.ConsumerMgrServiceSkeleton#addDevice</faultstring>
<detail/>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>

apparently meaning that the soap message was validated. How can this be?! m0:attributes is defined as a complextype for which abstract="true". That means that it is invalid for it to appear in an actual instance! Is the abstract attribute not supported by Axis???

The second soap message I sent was:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:m0="http://consumermgr.sss.com/consumermgr">
<SOAP-ENV:Body>
<m:addDevice xmlns:m="http://consumermgr.sss.com" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<addDeviceInputParam>
<m0:header>
<m0:timestamp>2001-12-17T09:30:47.0Z</m0:timestamp>
<m0:fromId>0</m0:fromId>
</m0:header>
<m0:deviceId>
<m0:idType/>
<m0:id/>
</m0:deviceId>
<m0:attributes xsi:type="STBAttributeSetType"><m0:password>MyPW</m0:password></m0:attributes>/>
</addDeviceInputParam>
</m:addDevice>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The Response was:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Client</faultcode>
<faultstring>java.lang.RuntimeException: Unsupported type null STBAttributeSetType</faultstring>
<detail/>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>

Now in my schema STBAttributeSetType is defined as extending an abstract complex type. <attributes> is of type that abstract type. Therefore the axis-generated server code should like STBAttributeSetType. Does the "Unsupported type" error it returns mean that axis doesn't support complextype inheiritance?
