Creating from a Stored Function

The EclipseLink DBWS can create of a Web service that exposes a simple Stored Function.

Example

In this example, the following stored function will be used:

DROP FUNCTION TESTECHO;
CREATE OR REPLACE FUNCTION TESTECHO(T IN VARCHAR2) RETURN VARCHAR2 IS retVal VARCHAR2
BEGIN
	retVal := CONCAT('test-' , T);
	RETURN retVal;
END TESTECHO;

The DBWSBuilder utility requires a DBWS configuration XML file as input, as shown here:

<?xml version="1.0" encoding="UTF-8"?>
<dbws-builder xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <properties>
    <property name="projectName">testEcho</property>
    ... database properties
  </properties>
  <procedure
    name="testEcho"
    procedurePattern="TESTECHO"
    returnType="xsd:string"
  />
</dbws-builder>

Execute the DBWSBuilder, as shown here:

prompt > dbwsbuilder.cmd -builderFile dbws-builder.xml -stageDir output_directory -packageAs wls testEcho.war

where

• dbws-builder.xml is the DBWS builder configuration XML file above
• output_directory is the output directory for the generated files
• -packageAs the platform on which the web service will be deployed
