BeanSerializer is missing xsi:tye

[Kesav Kumar]

BeanSerializer is not adding xsi:type if the value of the field is null.  If xsi:type is missing then the server is not able to deserialize.   I am using axis nightly drop of 05-31 on client side and soap toolkit which comes along with Websphere on the server end.  Does any one experience the same problem?   Here is the SOAP xml generated by Axis   <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">  <SOAP-ENV:Body>   <ns1:baseletGetIds xmlns:ns1="http://boulder.ibm.com/com.ibm.pdc.cis.sri.baselet.BaseletBean">    <searchParameter href="#id0"/>   </ns1:baseletGetIds>   <multiRef id="id0" SOAP-ENC:root="0" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="ns2:com.ibm.pdc.cis.sri.baselet.domain.BaseletSearchBean" xmlns:ns2="http://www.baseletbean.com/schemas/BaseletBeanRemoteInterface">    <ns2:baseletRole xsi:nil="true"/>    <ns2:baseletName xsi:nil="true"/>    <ns2:baseletDirectoryLocation xsi:nil="true"/>    <ns2:baseletModificationStartDate xsi:nil="true"/>    <ns2:baseletClinicalCondition xsi:nil="true"/>    <ns2:baseletModificationEndDate xsi:nil="true"/>    <ns2:baseletType xsi:nil="true"/>    <ns2:baseletState xsi:type="xsd:int">1</ns2:baseletState>    <ns2:baseletHasBeenInserted xsi:nil="true"/>    <ns2:baseletSource xsi:nil="true"/>    <ns2:baseletIsEnterprise xsi:nil="true"/>    <ns2:baseletCreationStartDate xsi:nil="true"/>    <ns2:baseletHasLinks xsi:nil="true"/>    <ns2:baseletAuthorId xsi:nil="true"/>    <ns2:baseletClinicalDomain xsi:nil="true"/>    <ns2:baseletKeyword xsi:nil="true"/>    <ns2:baseletCreationEndDate xsi:nil="true"/>    <ns2:baseletLanguage xsi:nil="true"/>    <ns2:baseletSponsor xsi:nil="true"/>    <ns2:CMTId xsi:nil="true"/>   </multiRef>  </SOAP-ENV:Body> </SOAP-ENV:Envelope>     There are two things which are wrong   1) the xsi:type is missing if the objec property value is null 2) It is adding namespace before each property of the bean.   I looked into the C:\xml-axis\java\src\org\apache\axis\encoding\SerializationContextImpl.java for the problem 1 i.e missing the type In the serialize method if the attribute value is null populating the xmlType is missing.   Old code           if (value == null) {             // If the value is null, the element is             // passed with xsi:nil="true" to indicate that no object is present.             if (sendNull) {                 AttributesImpl attrs = new AttributesImpl();                 if (attributes != null && 0 < attributes.getLength())                     attrs.setAttributes(attributes);                 if (sendType)                     attrs = (AttributesImpl) setTypeAttribute(attrs, xmlType);                 attrs.addAttribute(Constants.NS_URI_2001_SCHEMA_XSI, "nil", "xsi:nil",                                    "CDATA", "true");                 System.out.println("KKK: elemQName=" + elemQName);                 startElement(elemQName, attrs);                 endElement();             }             return;         }   Modification required           if (value == null) {             // If the value is null, the element is             // passed with xsi:nil="true" to indicate that no object is present.             if (sendNull) {                 AttributesImpl attrs = new AttributesImpl();                 if (attributes != null && 0 < attributes.getLength())                     attrs.setAttributes(attributes);                 if (sendType) { // Here the xmlType needs to obtained from the typemapping.                      TypeMapping tm = getTypeMapping();                     if (xmlType == null) {                         xmlType = tm.getTypeQName(javaType);                     }                     attrs = (AttributesImpl) setTypeAttribute(attrs, xmlType);                     }                 attrs.addAttribute(Constants.NS_URI_2001_SCHEMA_XSI, "nil", "xsi:nil",                                    "CDATA", "true");                 System.out.println("KKK: elemQName=" + elemQName);                 startElement(elemQName, attrs);                 endElement();             }             return;         }   Please let me know if I am wrong and please suggest me where to look for the namespace issue.   Thanks in advance Kesav Kumar
