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