BPEL

BPEL is an XML programming language. As aprogramming language it has three basic components:

• Programming logic• Data types• Input/Output (I/O)BPEL splits these components up in the following way: • Programming logic - BPEL• Data types - XSD (XML Schema Definition)• Input/Output (I/O) - WSDL (Web Services Description

Language)

An Example of “hello word” programwith Bpel

<?xml version="1.0" encoding="UTF-8"?><process xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"

xmlns:print="http://www.eclipse.org/tptp/choreography/2004/engine/Print"> <!--Hello World - my first ever BPEL program -->

<import importType="http://schemas.xmlsoap.org/wsdl/" location="../../test_bucket/service_libraries/tptp_EnginePrinterPort.wsdl" namespace="http://www.eclipse.org/tptp/choreography/2004/engine/Print" />

<partnerLinks> <partnerLink name="printService" partnerLinkType="print:printLink"

partnerRole="printService"/> </partnerLinks><variables> <variable name="hello_world" messageType="print:PrintMessage" />

</variables><assign> <copy> <from><literal>Hello World</literal></from>

<to>$hello_world.value</to> </copy> </assign><invoke partnerLink="printService" operation="print" inputVariable="hello_world"
