Web service API requirements for BPEL processes and human tasks

BPEL processes and human tasks developed with IBM Integration Designer to run on Business Process Choreographer must conform to specific rules to be accessible through the web services APIs.

The requirements are:

• The interfaces of BPEL processes and human tasks must be defined using the "document/literal wrapped" style defined in the Java™ API for XML-based Web Services (JAX-WS 2.0) specification. This is the default style for all BPEL processes and human tasks developed with Integration Designer.
• Do not use the maxOccurs attribute in parameter elements of the operations, or ensure that the value of this attribute is set to the default value, maxOccurs="1".
• Fault messages that are exposed by BPEL processes and human tasks for web service operations must comprise a single WSDL message part defined with an XML Schema element.

  For example:

  <wsdl:part name="myFault" element="myNamespace:myFaultElement"/>
