JAX-RPC Mapping DD, what metadata is used by JBoss?

ilchen Aug 31, 2005 8:28 AM

In using the WS subsystem of JBoss, I observed that it ignores a fair amount of metadata supplied in a JAX-RPC Mapping DD. In particular I observed the following:

1. java-xml-type-mapping. Jboss ignores the xml-element-name element on the assumption that its value is the same as that of java-variable-name. E.g. with the following info in the typemapping DD, JBoss will fail to deserialize incoming requests:

<java-type>pack.JavaType</java-type>
 <root-type-qname xmlns:typeNS="http://namesp">typeNS:XMLType</root-type-qname>
 <qname-scope>complexType</qname-scope>
 <variable-mapping>
 <java-variable-name>typedElements</java-variable-name>
 <xml-element-name>collectionElements</xml-element-name>
 </variable-mapping>
 </java-xml-type-mapping>

2. java-xml-type-mapping. JBoss ignores information provided by element bindings in favour of JavaBean introspection. In other words, given the following:

class St {
 private Interface s;
 Interface getS() { return s; }
 void setS(Interface s) { this.s = s; }
}

class RefType implements Interface {...}

 <xsd:complexType name="St">
 <xsd:all>
 <xsd:element name="s" type="tns:RefType"/>
 </xsd:all>
 </xsd:complexType>

 <xsd:complexType name="RefType">
 <xsd:all>
 ...
 </xsd:all>
 </xsd:complexType>

I want to ensure that the s element of the St complex type is mapped not to the Interface class but to the RefType class. To accomplish that I do the following:

a) Map XML St to Java St:

<java-xml-type-mapping>
 <java-type>St</java-type>
 <root-type-qname xmlns:typeNS="http://namesp">typeNS:St</root-type-qname>
 <qname-scope>complexType</qname-scope>
 <variable-mapping>
 <java-variable-name>s</java-variable-name>
 <xml-element-name>s</xml-element-name>
 </variable-mapping>
 </java-xml-type-mapping>

b) Map XML RefType to Java RefType:

<java-xml-type-mapping>
 <java-type>RefType</java-type>
 <root-type-qname xmlns:typeNS="http://namesp">typeNS:RefType </root-type-qname>
 <qname-scope>complexType</qname-scope>
 <variable-mapping>
 ...
 </variable-mapping>
 </java-xml-type-mapping>

c) Map the s element of St to RefType to prevent it from being taken as the Interface class through JavaBean introspection:

<java-xml-type-mapping>
 <java-type>RefType </java-type>
 <anonymous-type-qname>http://namesp:St>s</anonymous-type-qname>
 <qname-scope>element</qname-scope>
 </java-xml-type-mapping>

JBoss correctly processes a and b but completely disregards c, thus failing to support this scenario.

3. exception-mapping. JBoss ignores information provided by constructor-parameter-order...

It would be very beneficial for the JBoss community if it were clarified what metadata from JAX-RPC Mapping DDs is actually used by JBoss and what ignored.

Thank you in advance.

We observer a similary problem. The MetaData in the generated WSDD file are mostly ignored by the Serializer.

The follwoing web service:

<?xml version="1.0" encoding="UTF-8"?>

Got this SOAPRequest:

 </soapenv:Body>
</soapenv:Envelope>

We receive the following SOAPResponse

<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">

 <city>
 <name>Berlin</name>
 </city>
 <street>
 <name>Potsdamer Platz</name>
 </street>
 </location>
 </ns1:findPhoneLocationResponse>
 </soapenv:Body>
</soapenv:Envelope>

All prefixes and namespaces of the enclosed Response data are omited and we like to have them for later processing.

Also debugging shows, that the Serialization favours JavaBean MetaData, which do not provide the full QName. Is this a bug ? and is there some configuration option to enforce all namespaces in SOAPResponse?

It is a pity that such an important issue still hasn't been commented on by JBoss developers...
