Question

I am using JibX as a Java Object to XML Binding tool.

With it, I want to have the following output:

<?xml version='1.0' encoding='UTF-8'?> <FEAPService>     <Request>         <Function>aaa</Function>         <SubFunction>bbb</SubFunction>         <Operation>ccc</Operation>     </Request> </FEAPService> 

But I’m getting this:

<?xml version='1.0' encoding='UTF-8'?> <FEAPService>     <Request>         <baseForm> <!-- I DO NOT WANT THIS baseForm TAG -->             <Function>aaa</Function>             <SubFunction>bbb</SubFunction>             <Operation>ccc</Operation>         </baseForm>     </Request> </FEAPService> 

Here’s the JibX binding file:

<binding name='requestBinding_com_struts_form_SpecificForm'>     <mapping name='baseForm' class='com.struts.form.BaseForm'>         <value name='Function' field='function' />         <value name='SubFunction' field='subFunction' />         <value name='Operation' field='operation' />     </mapping>         <mapping name='FEAPService' class='com.struts.form.SpecificForm'         extends='com.struts.form.BaseForm'>         <structure name='Request'>             <structure map-as='com.struts.form.BaseForm' />         </structure>     </mapping> </binding> 

I guess it might be achieved by implementing my own Marshaller, but I’m not sure if that’s the easiest way.

I managed to remove the undesired XML node, there are 2 ways:

1. the easy way: just use the abstract=’true’ attribute.
2. the hardcore way: implement your own marshaller.

1st option:

<mapping class='com.struts.form.BaseForm' abstract='true'>         <value name='Function' field='function' />         <value name='SubFunction' field='subFunction' />         <value name='Operation' field='operation' />         <value name='doubleField_part1' field='doubleField' serializer='com.struts.form.BaseForm.doubleFieldDeserializer1' />         <value name='doubleField_part2' field='doubleField' serializer='com.struts.form.BaseForm.doubleFieldDeserializer2' />     </mapping> 

2nd option: implement your own Marshaller:

public class MyMarshaller implements IMarshaller {     private static final String FUNCTION_ELEMENT_NAME = 'Function';     private static final String SUB_FUNCTION_ELEMENT_NAME = 'SubFunction';     private static final String OPERATION_ELEMENT_NAME = 'Operation';      private String m_uri;     private int m_index;     private String m_name;      public MyMarshaller() {         m_uri = null;         m_index = 0;          m_name = 'Function';     }      public MyMarshaller(String uri, int index, String name) {         m_uri = uri;         m_index = index;         m_name = name;     }      public boolean isExtension(int index) {         return false;     }      public void marshal(Object obj, IMarshallingContext ictx)             throws JiBXException {          // make sure the parameters are as expected         if (!(obj instanceof BaseForm)) {             throw new JiBXException('Invalid object type for marshaller');         } else if (!(ictx instanceof MarshallingContext)) {             throw new JiBXException('Invalid object type for marshaller');         } else {             // start by generating start tag for container             MarshallingContext ctx = (MarshallingContext) ictx;             BaseForm formBean = (BaseForm) obj;              /*              * THIS CODE COULD BE REPEATED FOR ALL FormBean CLASS' ATTRIBUTE USING REFLECTION.              * And to control which attributes should be marshalled the attributes could follow special nomeclatures.              * Ex.              * class FormBean {               *    String marshallable_Function;              *    String non_marshallable_Function;              * }              */              writeTag(ctx, formBean.getFunction(), FUNCTION_ELEMENT_NAME);             writeTag(ctx, formBean.getSubFunction(), SUB_FUNCTION_ELEMENT_NAME);             writeTag(ctx, formBean.getOperation(), OPERATION_ELEMENT_NAME);         }     }      private void writeTag(MarshallingContext ctx, String value, String entryElementName)             throws JiBXException {         ctx.startTag(m_index, entryElementName);         ctx.closeStartContent();         ctx.content(value);         ctx.endTag(m_index, entryElementName);     } }

And here is my binding.xml:

<binding name='requestBinding_com_struts_form_SpecificForm'>     <mapping class='com.struts.form.BaseForm' marshaller='example8.MyMarshaller' />             <mapping name='FEAPService' class='com.struts.form.SpecificForm'>         <structure name='Request'>             <structure map-as='com.struts.form.BaseForm' />         </structure>     </mapping> </binding>
