If the event carries the employee's ID, you can use a custom XPath function to re-
move the salary information from the web service response. It is recommended to
use the Oracle-provided (
oracle.fabric.common.xml.xpath
) public interface
IXPathFunction
for implementing a custom XPath function in SOA components.
Creating custom XPath functions
To define custom functions, you need to perform the following steps:
1. Create a new Java project in JDeveloper and add the SOA runtime and
parser libraries.
2. Write a custom XPath function class.
3. Configure the custom XPath expression function class with JDeveloper
and SOA Suite.
4. Deploy user-defined functions to runtime.
5. Start using the custom function from JDeveloper.
6. As shown in the following screenshot, add
SOA Runtime
and
Oracle
XML Parser v2
to the libraries of your Java project by choosing
Project
Properties
. Right-click on the Java project to view
