> Key: XMLBEANS-426
> URL: https://issues.apache.org/jira/browse/XMLBEANS-426
> Project: XMLBeans
> Issue Type: Bug
> Components: Binding
> Affects Versions: Version 2.4
> Environment: Windows OS, WAS 6.1, xbean-2.4.0. AXIS2 with XMLBeans binding for SOAP requests at client side. AXIS2 with ADB bindings at server side.
> Reporter: Pundarikakshaiah Ganduri
> Priority: Blocker
> Fix For: Version 5.1.0
>
> Original Estimate: 504h
> Remaining Estimate: 504h
>
> In my project we are using AXIS2 along with XMLBeans binding to generate the payload classes for the web services. The XSD has an element like <xs:element name="LoanPurposeDesc" type="xs:string" minOccurs="0" />
> The generated SOAP request xml contains the empty element for this field "LoanPurposeDesc" with a xsi:nil="true" attribute as shown below.
> <mtv1:LoanPurposeDesc xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
> This is causing the parsing error message on the receiving end of the SOAP request.
> Due to this the parser is throwing the error like for the element that is of SimpleType the only expected attribute is its namespace declaration.
> For time being to avoid this issue I have modified following way:
> Changed XSD to modify the defintion of that element as:
> <xs:element name="LoanPurposeDesc" type="xs:string" minOccurs="0" nillable="true"/>
> And changed the printSetterImpls() method of org.apache.xmlbeans.impl.schema.SchemaTypeCodePrinter class so that it calls the unSet methd of a property if the property value is coming as null as below:
> if (nillable
> && optional
> && !(javaType >= SchemaProperty.JAVA_FIRST_PRIMITIVE && javaType <= SchemaProperty.JAVA_LAST_PRIMITIVE)) {
> emit("if ("+safeVarName+" == null){");
> emit("\tunset" + propertyName + "();");
> emit("return;");
> emit("}");
>
> }
> Please provide a resolution for this or confirm if we can use the changes I have specified.
