Description

Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex makes use of soap enc array currently unsupported by many if not all JAX tools. I currently solved this by modifying Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex; instead I use a sequence of objects, so I changed from:


            $complexType = $dom->createElement('xsd:complexType');
            $complexType->setAttribute('name', $xsdComplexTypeName);

            $complexContent = $dom->createElement("xsd:complexContent");
            $complexType->appendChild($complexContent);

            $xsdRestriction = $dom->createElement("xsd:restriction");
            $xsdRestriction->setAttribute('base', 'soap-enc:Array');
            $complexContent->appendChild($xsdRestriction);

            $xsdAttribute = $dom->createElement("xsd:attribute");
            $xsdAttribute->setAttribute("ref", "soap-enc:arrayType");
            $xsdAttribute->setAttribute("wsdl:arrayType", sprintf("tns:%s[]", $singularType));
            $xsdRestriction->appendChild($xsdAttribute);

            $this->getContext()->getSchema()->appendChild($complexType);
            $this->getContext()->addType($xsdComplexTypeName);


            $complexType = $dom->createElement('xsd:complexType');
            $complexType->setAttribute('name', sprintf('%s',$xsdComplexTypeName));

            $complexContent = $dom->createElement("xsd:sequence");
            $complexType->appendChild($complexContent);

            $xsdRestriction = $dom->createElement("xsd:element");
            $xsdRestriction->setAttribute('name', $singularType);
            $xsdRestriction->setAttribute('type', sprintf('tns:%s',$singularType));
            $xsdRestriction->setAttribute('minOccurs','0');
            $xsdRestriction->setAttribute('maxOccurs','unbounded');
            $complexContent->appendChild($xsdRestriction);

            $this->getContext()->getSchema()->appendChild($complexType);
            $this->getContext()->addType($xsdComplexTypeName);

So the generated wsdl changes from:

to:

Works for me and can be imported using JAX wsimport

Two weeks ago Benjamin and I talked about exactly this way how to solve the problem with other clients than php's SoapClient. I'll take a look at it to check if my problems will be solved by changing the code like mentioned.

@Erick: seems to work fine. i've sent Benjamin my test environment in hope he can test it :-) didn't you need to add the "namespace"-attribute to ? my wsimport cannot create java sources/binaries without having this attribute.

@Benjamin: do we now need junit tests? we should check if we need the "namespace"-attribute for all elements.

Jan: I'm not sure but I think I grabbed a version of Zend_Soap_Autodiscover from SVN trunk that can set namespace as you say. I'll check this later. About the wsimport you posted, which version of Zoap_Wsdl_Strategy_ArrayOfTypeComplex are you using? did you add namespace attribute?

Posted by Benjamin Eberlei (beberlei) on 2009-05-30T15:47:20.000+0000

Is the problem that Zend_Soap_Wsdl_Strategy_ArrayOfTypeSequence does not support complex types?

I guess the whole fun of strategies was to fix these problems to their specific kinds.

Does this issue go if ArrayOfTypeSequence supports complex types as suggested in ZF-6742? Would this patch fix your problem?

I am trying to implement this fix it is needed for our workflow engine to work since it uses JAX. I have made the code change from above and still no luck. I am running latest version of ZF.
