Using Scripting

Log on to the integration flow DelayedDelivery_Process via Integration Suite.

1. Navigate within the Integration Suite Welcome page to Design → Integrations → DelayedDelivery_Package_randomNumber → DelayedDelivery_Process.

2. Following the status after the last exercise step.

   

3. Let's assume that the integration flow has been further edited.

Create a Groovy Script.

1. Set Transformation >Script > Groovy Script component within the Exception Subprocess.

   

2. Rename it to Script_readExceptionMessagesToPayload.

   

Write a Groovy Script.

1. Use the Create icon from the context menu of Script_readExceptionMessagesToPayload component.

   

   An editor opens.

2. Enter the following data:

   import com.sap.gateway.ip.core.customdev.util.Message;
   import java.util.HashMap;
   import groovy.xml.MarkupBuilder;
   def Message processData(Message message) {
    //Body 
    def body     = message.getBody();
    def props    = message.getProperties(); 
    def exStacktrace = props.get("exStacktrace");
    def exMessage = props.get("exMessage"); 
    def stringWriter = new StringWriter();
    def exceptionBuiler = new MarkupBuilder(stringWriter); 
    exceptionBuiler.exception {
    exceptionMessage(exMessage)
    stacktrace(exStacktrace)
    } 
    message.setHeader("Content-Type", "application/xml")
    message.setHeader("CamelHttpResponseCode", 500) 
    message.setBody(stringWriter.toString());
    
    def messageLog = messageLogFactory.getMessageLog(message);
    if(messageLog != null) {
    messageLog.addAttachmentAsString("Exception Messages", message.getBody(), "text/plain")
    }
    
    return message;
   }

   

3. Choose the OK button to save your work.

4. Navigate back to your Integration Process via bread crumb navigation.

Save as version, deploy, and debug your integration process

1. Perform the following steps:

   1. Save as version.
   2. Deploy.
   3. Jump to Overview → Manage Integration Content.
   4. Set log level to trace.
   5. Deploy again.
   6. Jump again to Overview → Manage Integration Content.

2. Navigate to your integration flow Model in Overview > Monitor Message Processing >Message Processing Run.

Test without an Exception.

1. We use the same URLs as before, that is, the connections work and we do not go through an error. Everything should work as before.

   

Test with an exception.

1. Navigate to the Call_fetchLineItems HTTP connectivity. At the tab Connection, change the URL so that it no longer works.

   

2. Save and Deploy again, and check your Monitor.

3. At Overview > Monitor Message Processing.

   

4. The message status is Completed and an error message has been created. Check the messages.

5. To see the integration flow Model in more detail, navigate to Trace.

   

6. An Exception occurs and the Exception Subprocess is called.

7. Everything works as expected.

8. Remove the error in the URL again so that everything runs without errors again.

Learn more about the Groovy Scripting operations.

1. Navigate back to your Integration Process, open the configuration bar of the Script_readExceptionMessagesToPayload component and choose the question marksymbol.

Log on to the integration flow DelayedDelivery_Process via Integration Suite

1. Navigate within the Integration Suite Welcome page to Design > Integrations > DelayedDelivery_Package_randomNumber > DelayedDelivery_Process.

2. Following the status after the last exercise step.

   

3. Imagine that the integration flow has been further modified.

Substitute the timer event with a message start event.

1. Move the timer event to the left to create space for the message start event.

   

2. Choose Event → Start Message.

   

3. Place it immediately adjacent to the timer event.

   

4. Delete the timer event.

   

5. Rename the start event to Event_startMessage.

   

Delete the Modify_setPayload component.

1. Delete the Modify_setPayload component.

   

2. This segment of your integration flow should look like this now.

   

3. Choose the Save button.
