Custom Serializer writeSchema() - adding xsd:import and wrapped arrays

[Ben Reif <be...@gmail.com>]

Hey everyone,

I have two questions regarding generating schema with custom serializers.
I'm using Axis 1.3 and I have some complex type objects that I want to
expose in a Web Service. These objects aren't pure Java Beans so I had to
write my own custom serializer and deserializer. These objects have getters
and setters that deal with Lists of other complex type objects. In the
writeSchema() method of my serializer I add an element to handle the
getters/setters as arrays. When I run wsdl2java the schema in the WSDL comes
out like this:

<schema elementFormDefault="qualified" targetNamespace="
http://my.class.package.name" xmlns="http://www.w3.org/2001/XMLSchema">
    <complexType name="MyClass1">
                <sequence>
                    <element maxOccurs="1" minOccurs="0" name="myClass2s"
nillable="true" type="tns2:ArrayOfMyClass2"/>
                </sequence>
    </complexType>
</schema>

I have tns2:ArrayOfMyClass2 defined farther down in the types section of the
WSDL and it's in a different namespace then MyClass1. When I validate the
WSDL it says that it's invalid because it's missing an <xsd:import
namespace=http://my.class2.package.name/> from the above <schema>
definition. My question is how can I add this import from the writeSchema()
method in my serializer? The org.apache.wsdl.fromJava.Types class doesn't
give you access to the WSDL document as a whole, or even the current
<schema> element that's being written. Does anyone know of a way to do this?


My second question is that my service has methods that take in object
arrays. So in my WSDD file I have <arrayMappings> defined and the schema in
my WSDL I have wrapped array types like this:

<complexType name="ArrayOfMyClass">
    <sequence>
        <element maxOccurs="unbounded" minOccurs="0" name="MyClass"
type="tns1:MyClass"/>
    </sequence>
</complexType>

The problem is that when I run wsdl2java the operation definitions in the
default namespace <schema> section of the <wsdl:types> come out like:

<element name="myOperation">
    <complexType>
        <sequence>
            <element maxOccurs="unbounded" name="ArrayOfMyClass"
type="tns1:MyClass"/>
        </sequence>
    </complexType>
</element>

This is incorrect because the maxOccurs should be 1, not unbounded, since
it's a wrapped array type. It doesn't seem like the
org.apache.wsdl.fromJava.Types has any methods to write out a wrapped array
definition and it doesn't give you access to change this. Does anyone know
how this can be done?

If anyone knows how to accomplish either of these thanks in advance,

Ben

Sorry, in the email below I meant that I ran the java2wsdl utility.
