Generated XML from an XSD contains xsi:nil="true" attribute for an optional
(minOccurs="0") SimpleType element causing issue while processing of SOAP
request
-------------------------------------------------------------------------------------------------------------------------------------------------------------
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
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.
