Chapter 7. Using SOAP 1.2 Messages


Apache CXF provides tools to generate a SOAP 1.2 binding which does not use any SOAP headers. You can add SOAP headers to your binding using any text or XML editor.

7.1. Adding a SOAP 1.2 Binding to a WSDL Document

Using wsdl2soap

To use wsdl2soap you will need to download the Apache CXF distribution.
To generate a SOAP 1.2 binding using wsdl2soap use the following command:

wsdl2soap { -i port-type-name } [ -b binding-name ] { -soap12 } [ -d output-directory ] [ -o output-file ] [ -n soap-body-namespace ] [ -style (document/rpc) ] [ -use (literal/encoded) ] [ -v ] [[ -verbose ] | [ -quiet ]] wsdlurl

The tool has the following required arguments:
-i port-type-name
Specifies the portType element for which a binding is generated.
-soap12Specifies that the generated binding uses SOAP 1.2.
wsdlurlThe path and name of the WSDL file containing the portType element definition.
The tool has the following optional arguments:
-b binding-nameSpecifies the name of the generated SOAP binding.
-soap12Specifies that the generated binding will use SOAP 1.2.
-d output-directorySpecifies the directory to place the generated WSDL file.
-o output-fileSpecifies the name of the generated WSDL file.
-n soap-body-namespaceSpecifies the SOAP body namespace when the style is RPC.
-style (document/rpc)Specifies the encoding style (document or RPC) to use in the SOAP binding. The default is document.
-use (literal/encoded)Specifies the binding use (encoded or literal) to use in the SOAP binding. The default is literal.
-vDisplays the version number for the tool.
-verboseDisplays comments during the code generation process.
-quietSuppresses comments during the code generation process.
The -i port-type-name and wsdlurl arguments are required. If the -style rpc argument is specified, the -n soap-body-namspace argument is also required. All other arguments are optional and can be listed in any order.
wsdl2soap does not support the generation of document/encoded SOAP 1.2 bindings.


If your system has an interface that takes orders and offers a single operation to process the orders it is defined in a WSDL fragment similar to the one shown in Example 7.1, “Ordering System Interface”.

Example 7.1. Ordering System Interface

<?xml version="1.0" encoding="UTF-8"?>
<definitions name="widgetOrderForm.wsdl"

<message name="widgetOrder">
  <part name="numOrdered" type="xsd:int"/>
<message name="widgetOrderBill">
  <part name="price" type="xsd:float"/>
<message name="badSize">
  <part name="numInventory" type="xsd:int"/>

<portType name="orderWidgets">
  <operation name="placeWidgetOrder">
    <input message="tns:widgetOrder" name="order"/>
    <output message="tns:widgetOrderBill" name="bill"/>
    <fault message="tns:badSize" name="sizeFault"/>
The SOAP binding generated for orderWidgets is shown in Example 7.2, “SOAP 1.2 Binding for orderWidgets”.

Example 7.2. SOAP 1.2 Binding for orderWidgets

<binding name="orderWidgetsBinding" type="tns:orderWidgets">
  <soap12:binding style="document" transport=""/>
    <operation name="placeWidgetOrder">
      <soap12:operation soapAction="" style="document"/>
      <input name="order">
        <soap12:body use="literal"/>
      <output name="bill">
        <wsoap12:body use="literal"/>
      <fault name="sizeFault">
        <soap12:body use="literal"/>
This binding specifies that messages are sent using the document/literal message style.
