Creating property aliases
Property alias is for telling the BPEL process how to extract the value of the property
from the specified message. The property aliases assist us in mapping a property to
a field in a specific message part and that can be used in XPath expressions. Multiple
property aliases may be required for correlation, such as the one for instantiation and
another one for validation.
To create a property alias in JDeveloper, double-click on the
Property Aliases
icon,
as shown in the following screenshot. Select the correlation set to associate with a
property alias. If the message part is an element or a complex type, you can define an
XPath query to identify the location of the property within the element or type. In the
Query
field, add appropriate XPath expressions. An XPath expression is for navigat-
ing within an XML document and helps to directly define a part of the XML document.
