13. 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)

14. An Example of “hello word” programwith Bpel
<?xml version="1.0" encoding="UTF-8"?> <process xmlns=" xmlns:print=" <!--Hello World - my first ever BPEL program --> <import importType=" location="../../test_bucket/service_libraries/tptp_EnginePrinterPort.wsdl" namespace=" /> <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" /></process>

15. BPEL Skeleton
<xml version = “UTF -8 ”> Bpel : process xmlns:bpel =“ httpd ”… <bpel : sequence> (for Exclusive OR operation) <receive name : “receive input” partnerlink:….. (Start) <invoke “send request to task advicer”… / > <bpel:receive name = “Receive Form”> <input variable :“ ” output variable :”” > <bpel :invoke name =“Fill Form” > <bpel :receive name = “receive information”> …….. . ……………………

16. BPEL Skeleton
<bpel : invoke name = “pay a certain amount of service ” <switch (…) ../ > <case condition =“A” > <invoke name : “credit card”> <case condition= “B“> ( <otherwise> ) <invoke name : “cash”> <bpel:catchAll> <bpel : receive name = “receive output”> </bpel receive> </otherwise> </switch> ……………………. </bpel:sequence> </bpel:process> Not complete bpel specification of bpmn examle
