Parameters

Parameter

Description

data

The incoming message and any additional gateway-specific event data.

Usage

The number of fields and their contents depend on the event gateway type. The Map keys must be strings. Because ColdFusion is not case sensitive, it converts the Map passed in the setData method to a case insensitive Map. As a result, do not create entries in the data with names that differ only in case.

Example

The following code shows the routine from the example JMS gateway that handles incoming messages. It puts the JMS message ID and contents in a data HashMap, and uses it in the setData method:

public void handleMessage(String msg, String topicName, String msgID) {
coldfusion.eventgateway.Logger log = getGatewayServices().getLogger();
Map data = new HashMap();
CFEvent cfMsg = new CFEvent(getGatewayID());
data.put("msg", msg);
data.put("id", msgID);
cfMsg.setData(data);
cfMsg.setOriginatorID(topicName);
cfMsg.setGatewayType("JMS");
if (sendMessage(cfMsg)) {
log.info("Added message '" + msgID + "' to queue.");
} else {
log.error("Failed to add message '" + msgID + "' to queue.");
}
}
