Business Process Example

The following example illustrates how the Sleep service can be used in a business process. The first service in the business process is the Sleep service, which causes the business process to pause for 60 seconds, then uses the File System adapter to collect a file from a folder called “Test” on the local drive:

This is how the business process looks in the GPM:

This is the BPML for the business process:

<process name="default">
 <sequence>
    <operation name="Sleep Service">
      <participant name="SleepService"/>
     <output message="SleepServiceInputMessage">
       <assign to="SLEEP_INTERVAL">60</assign>
       <assign to="." from="*"></assign>
     </output>
      <input message="inmsg">
       <assign to="." from="*"></assign>
     </input>
    </operation>
   <operation name="File System Adapter">
     <participant name="Test"/>
      <output message="FileSystemInputMessage">
       <assign to="Action">FS_COLLECT</assign>
       <assign to="." from="*"></assign>
     </output>
      <input message="inmsg">
       <assign to="." from="*"></assign>
     </input>
    </operation>
 </sequence> 
</process>

This is the status message for the Sleep service step, which you can view from the Execution Manager after the business process completes:
