Apache Camel is an open source framework for message-oriented middleware. It uses a rule-based routing and mediation engine to implement Enterprise Integration Patterns (EIPs). The EIPs are implemented using Java objects. Camel has a application programming interface (or declarative Java domain-specific language) for configuring the routing and mediation rules.

The domain-specific language means that Apache Camel can support type-safe smart completion of routing rules in an integrated development environment using regular Java code without large amounts of XML configuration files, though XML configuration inside Spring Framework is also supported.

Camel is often used with Apache ServiceMix, Apache ActiveMQ and Apache CXF in service-oriented architecture projects.
