If you received an error, you can try and determine the cause by looking at the logs. There’s a
convenient View Log link found towards the top of the Multi-Protocol Gateway configuration page. You
can also view the logs from the main control panel by clicking on the View Logs icon.
At this point, you have created a multi-protocol gateway service that acts as a pass-thru and verified that
it works. Now you’ll add some more interesting functionality to the service.
2.2.3 Save the Running Configuration
Once you have your configuration running properly, it’s a good idea to save the configuration to the flash
memory. At this point, if the device was shut off or the power was disconnected, all of the work you’ve
done until now would be lost. Saving the configuration causes your domain to be written to the flash
memory, making it available after the device is restarted.
__1. At the top of the browser window, click on the Save Config link. You should see a message that
says “Configuration successfully saved” (above the first row of service icons).
2.3 Schema Validation
An XML Schema describes the structure of an XML document. Validating an XML document against a
schema is one step to assuring that the structure and content of the document is valid and safe. The
process of validating an XML document against a schema is generally considered to be processor
intensive, resulting in increased server load. For this reason, organizations often disable schema
validation in an effort to reduce load (and cost) on application servers, especially when they are running
on a mainframe. This is generally considered a security risk.
WebSphere DataPower SOA Appliances solve this problem by providing wirespeed schema validation to
messages before they reach the application server. Messages that fail validation are rejected by default
(this behavior can be customized).
In this section, you’ll add a new processing rule to your service that will ultimately perform a variety of
actions against the SOAP request.
Now you’ll add a schema validate action to the processing rule. You’ll configure the Validate action to
use the embedded schema in the WSDL you uploaded in the first lab.
