[PATCH] : Serializer should map java *type* to xsi:type, deserial
izer maps xsi:type to java *class*
Problem
------------
Currently, the SOAP 2.0 runtime requires that the type and the class of Java
objects be identical.
This makes it impossible to use interfaces (see sample). I consider this a
fundamental flaw which should
be fixed in the core.
Patch in diff -C3 format
---------------------------------
<<DeploymentDescriptor.java.diffC3>> <<TypeMapping.java.diffC3>>
<<TypeMappingSerializer.java.diffC3>>
<<XMLJavaMappingRegistry.java.diffC3>>
What this does:
1) deserializer: map xsi:type to *javaClass* to create new instance of. Get
the javaClass name from new dd isd:map attribute "javaClass"
2) serializer: map object's *javaType* to xsi:type. Get the javaType from
old dd isd:map attribute "javaType"
Note: patch is backward-compatible, i.e., if javaClass attribute is absent,
things work as before.
Sample
-----------
public interface PhoneNumber {
..
}
public interface Address {
public void setPhoneNumber(PhoneNumber phoneNumber);
public PhoneNumber getPhoneNumber();
..
}
public class server.PhoneNumberImpl implements PhoneNumber {
..
}
public class server.AddressImpl implements Address {
..
}
public class client.PhoneNumberImpl implements PhoneNumber {
..
}
public class client.AddressImpl implements Address {
..
}
<isd:mappings>
<isd:map encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:x="urn:xml-soap-address-demo" qname="x:address"
javaType="samples.addressbook.Address"
javaClass="samples.addressbook.AddressImpl"
java2XMLClassName="org.apache.soap.encoding.soapenc.BeanSerializer"
xml2JavaClassName="org.apache.soap.encoding.soapenc.BeanSerializer"/>
<isd:map encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:x="urn:xml-soap-address-demo" qname="x:phone"
javaType="samples.addressbook.PhoneNumber"
javaClass="samples.addressbook.PhoneNumberImpl"

Speaking about mappings. SOAP 2.0 deployment descriptor entry
(among other things) assosiates QName with a java class/interface,
incase name can not be determined at run-time (like names of method
argument list). This assosiation does not seem to be complete
without an xml schema element *type* field. Has anyone ever discussed
that?
