In-Depth Information
If necessary, we may need to expand the routing rule to show the details. For the
input message, we have the option of filtering the message, meaning that we can
choose what to call, based on the contents of the input message. If no filter expression
is provided, then all messages will be delivered to a single target.
The
Validate Semantic
field allows us to check that the input message is of the
correct format. This requires a schematron file and is covered in
Chapter 13
,
Building
Validation into Services
.
The
Assign Values
field allows us to set values using either the input message or
message properties. This is particularly useful when using adapters, as some of the
data required may be provided in adapter headers such as the input filename. This
may also be used to set adapter header properties, if invoking an adapter.
