EclipseLink DBWS Service based on Stored Function with complex PL/SQL arguments

The use-case for this example is the creation of a Web service that exposes a simple Stored Function containing complex PL/SQL arguments.

The following stored function will be used for this example:
FUNCTION F1(OLDREC IN ARECORD, FOO IN VARCHAR2) RETURN ARECORD IS arec ARECORD;
  BEGIN
    arec.T1 := OLDREC.T1;
    arec.T2 := OLDREC.T2;
    arec.T3 := OLDREC.T3;
    RETURN arec;
  END F1;
Type ARECORD is defined in PL/SQL Package SOMEPACKAGE as follows:
CREATE OR REPLACE PACKAGE SOMEPACKAGE AS
  TYPE TBL1 IS TABLE OF VARCHAR2(111) INDEX BY BINARY_INTEGER;
  TYPE TBL2 IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
  TYPE ARECORD IS RECORD (
    T1 TBL1,
    T2 TBL2,
    T3 BOOLEAN
  );
  FUNCTION F1(OLDREC IN ARECORD, FOO IN VARCHAR2) RETURN ARECORD;
END SOMEPACKAGE;
The DBWSBuilder utility requires a DBWS configuration file as input.
<?xml version="1.0" encoding="UTF-8"?>
<dbws-builder xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <properties>
    <property name="projectName">testPLSQLFunction</property>
    ... database properties
  </properties>
  <plsql-procedure
   name="plsqlfunction"
   catalogPattern="SOMEPACKAGE"
   procedurePattern="F1%"
   returnType="SOMEPACKAGE_ARECORD"
 />
</dbws-builder>
prompt > dbwsbuilder.cmd -builderFile dbws-builder.xml -stageDir output_directory -packageAs wls testPLSQLFunction.war

where

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