Creating a message body

If your client calls message-driven rule beans (MDB) for asynchronous message processing, you can create a message body that sets ruleset parameters in a hash map.

About this task

In message-driven rule beans (MDB), the message body ObjectMessage.setObject(java.io.Serializable) can also include ruleset parameters in a hash map that is identified by their name and value. See (Deprecated) Message-driven rule beans.

Procedure

Create the JMS object message by using the queue session.

ObjectMessage requestMessage = queueSessionReceiver.createObjectMessage();

Set the mandatory Rule Execution Server JMS properties.

requestMessage.setStringProperty("ilog_rules_bres_mdb_rulesetPath",	rulesetPath);
requestMessage.setStringProperty("ilog_rules_bres_mdb_status","request");

Optional: Get a reply message with the result of the execution.
```
requestMessage.setJMSReplyTo(replyTo);
```

Set the ruleset parameters.

HashMap<String, String> parameters = new HashMap<String, String>();
parameters.put("customer", customer);
parameters.put("order", order);
requestMessage.setObject(parameters);

Send the message.
```
queueSender.send(requestMessage);
```

Example

Here is the entire code sample:

ObjectMessage requestMessage = queueSessionReceiver.createObjectMessage();
requestMessage.setStringProperty("ilog_rules_bres_mdb_rulesetPath",	rulesetPath);
requestMessage.setStringProperty("ilog_rules_bres_mdb_status","request");
requestMessage.setJMSReplyTo(replyTo);
HashMap<String, String> parameters = new HashMap<String, String>();
parameters.put("customer", customer);
parameters.put("order", order);
requestMessage.setObject(parameters);
queueSender.send(requestMessage);
