JMS Message Structure

JMS messages have a standard structure. This structure includes the following sections:
                          • Header (required)
                          • Properties (optional)
                          • Body (optional)

• EMS supports messages up to a maximum size of 512MB
• JMS message Priority is in the range [0,9]. The default value is 4.
• When the EMS server has several messages ready to deliver to a consumer client, then it delivers messages with higher priority before those with lower priority.
