Message Objects in the WSDL Document

The WSDL document contains two types of message objects:

• Regular message object

• Batch message object

IEP uses the regular message object when you are sending in one message at a time. A batch message object is useful when you want to send in multiple messages.

<message name="MyStreamInput_Msg">
   <part name="input" element="typens:MyStreamInput_MsgObj"/>
</message>
<message name="MyStreamInputBatch_Msg">
   <part name="input" element="typens:MyStreamInputBatch_MsgObj"/>
</message>
<message name="StreamOutput0_Msg">
   <part name="output" element="typens:StreamOutput0_MsgObj"/>
</message>

If one of the messages in the batch message group fails to be processed appropriately in the IEP, others will fail as well.

With a single message object, message failure is on a one-by-one basis.
