The exchange that is sent over the JMS wire must conform to the JMS Message spec.

For the exchange.in.header the following rules apply for the header keys :

  • Keys starting with JMS or JMSX are reserved.

  • exchange.in.headers keys must be literals and all be valid Java identifiers (do not use dots in the key name).

  • Camel replaces dots and hyphens and the reverse when when consuming JMS messages:

    . is replaced by _DOT_ and the reverse replacement when Camel consumes the message.

    - is replaced by _HYPHEN_ and the reverse replacement when Camel consumes the message.

  • See also the option jmsKeyFormatStrategy, which allows you to use your own custom strategy for formatting keys.

For the exchange.in.header, the following rules apply for the header values :

  • The values must be primitives or their counter objects (such as Integer, Long, Character). The types, String, CharSequence, Date, BigDecimal and BigInteger are all converted to their toString() representation. All other types are dropped.

Camel will log with category org.apache.camel.component.jms.JmsBinding at DEBUG level if it drops a given header value. For example: 

2008-07-09 06:43:04,046 [main           ] DEBUG JmsBinding  
- Ignoring non primitive header: order of class: org.apache.camel.component
.jms.issues.DummyOrder with value: DummyOrder{orderId=333, itemId=4444, 
quantity=2}
