RE: Default type mapping (another attempt)

Title: Message

Glen, so then if we change it to <foo xsi:type="java:org.apache.axis.mypackage.MyClass">, then do you agree it's good to have the "deployment-free" typemapping in Axis?

 

I'm not sure it's going to interop well with .NET... With the current http://my.app.corp.etc mapping it interops just fine...

 

Also I thought XML Schema suggests that XML namespaces resemble packages in OO model, aren't they?

Axis may become too Java centric in its introp if we ignore this, IMO.

-1

 

I don't think this is the right solution to this.

 

IMO, we shouldn't map java types to individual namespaces per package, but if we want a "deployment-free" typemapping (i.e. one where the QName of the type gives us enough info to figure out the java type), we should go with a syntax like:

 

<foo xsi:type="java:org.apache.axis.mypackage.MyClass">....

 

This seems way cleaner to me, and will interoperate, if we do it right, with GLUE and WASP and other java toolkits which use this pattern.

I'm trying it again.

The WSDL2Java and Java2WSDL take care of properly mapping http://my.app.corp.etc namespaces back to and from etc.corp.app.my packages (see code fragments below). SOAP processing pipeline does not. It always assumes the typemappings must have been provided by the service deployer. I'd like to make an attempt to sligtly modify DefaultTypeMappingsImpl to take care of this by default.

I know we had discussion before, but it has faded out and there was no coherent +1 or -1 on this. So let me try to start my +1.

Here is the code in WSDL2Java and java2WSDL that I was referring to
=== in axis.wsdl.fromJava.Types.getTypeQName(Class type) ===
                String pkg = getPackageNameFromFullName(type.getName());
                String lcl = getLocalNameFromFullName(type.getName());

                String ns = namespaces.getCreate(pkg);
                String pre = namespaces.getCreatePrefix(ns);
                String localPart = lcl.replace('$', '_');
                qName = new javax.xml.rpc.namespace.QName(ns, localPart);

=== in axis.wsdl.toJava.Utils.makePackageName(String namespace) ===
        //convert illegal java identifier
        hostname = hostname.replace('-', '_');

        // tokenize the hostname and reverse it
        StringTokenizer st = new StringTokenizer( hostname, "." );
        String[] words = new String[ st.countTokens() ];
        for(int i = 0; i < words.length; ++i)
            words[i] = st.nextToken();

        StringBuffer sb = new StringBuffer(80);
        for(int i = words.length-1; i >= 0; --i) {
            String word = words[i];
            if (JavaUtils.isJavaKeyword(word)) {
                word = JavaUtils.makeNonJavaKeyword(word);
            }
            // seperate with dot
            if( i != words.length-1 )
                sb.append('.');

            // convert digits to underscores
            if( Character.isDigit(word.charAt(0)) )
                sb.append('_');
            sb.append( word );
        }
        return sb.toString();
