Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the early version of the new website
We would very much like to receive any feedback on the new site, please join the discussion on the Camel user mailing list.

Guaranteed Delivery

Camel supports the Guaranteed Delivery from the EIP patterns using among others the following components:

  • File for using file systems as a persistent store of messages
  • JMS when using persistent delivery (the default) for working with JMS Queues and Topics for high performance, clustering and load balancing
  • JPA for using a database as a persistence layer, or use any of the many other database component such as SQL, JDBC, iBATIS/MyBatis, Hibernate
  • HawtDB for a lightweight key-value persistent store


The following example demonstrates illustrates the use of Guaranteed Delivery within the JMS component. By default, a message is not considered successfully delivered until the recipient has persisted the message locally guaranteeing its receipt in the event the destination becomes unavailable.

Using the Fluent Builders



Using the Spring XML Extensions

	<to uri="jms:queue:foo"/>

Using This Pattern

If you would like to use this EIP Pattern then please read the Getting Started, you may also find the Architecture useful particularly the description of Endpoint and URIs. Then you could try out some of the Examples first before trying this pattern out.
