Code to access binding-specific headers
Accessing the binding-specific headers from a SMO header in a data handler requires only a few lines of code.
Access SMO headers in data handlers
The following programming examples show how the header information can be accessed by the data handlers.
Access the properties section of an SMO header
Consider the case where there is a property called businessObjectName in the properties section of the SMO header.
1 DataObject header = (DataObject) ContextService.INSTANCE.getHeaders(); 2 List<DataObject> userPropertiesList = header.getList("properties"); 3 for (DataObject userProperty : userPropertiesList) { 4 String name = userProperty.getString("name"); 5 if (name.equals("businessObjectName")) { 6 String businessObjectName = userProperty.getString("value"); 7 } 8 }
Access a JMS header from an SMO header
To access the JMS header from the SMO header, you would use the following code:
9 DataObject header = (DataObject) ContextService.INSTANCE.getHeaders(); 10 DataObject jmsHeader = header.getDataObject("JMSHeader"); 11 String jmsMessageID = jmsHeader.get(“JMSMessageID”);
Access an MQ header from an SMO header
To access the MQ header from the SMO header, you would use the following code:
12 DataObject header = (DataObject) ContextService.INSTANCE.getHeaders(); 13 DataObject mqHeader = header.getDataObject("MQHeader"); 14 DataObject mqmd = mqHeader.get(“md”);
Access an HTTP header from an SMO header
To access the HTTP header from the SMO header, you would use the following code:
15 DataObject header = (DataObject) ContextService.INSTANCE.getHeaders(); 16 DataObject httpHeader = header.getDataObject("HTTPHeader"); 17 DataObject httpControl = mqHeader.get(“HTTPControl”);
Access an EIS Flat File header from an SMO header
To access the EIS Flat File header from the SMO header, you would use the following code:
18 DataObject header = (DataObject) ContextService.INSTANCE.getHeaders(); 19 DataObject eisHeader = header.getDataObject("EISHeader"); 20 DataObject eisIneractionSpec = mqHeader.get(“EISInteractionSpec”);
