The Spring configuration is used for configuring Camel routes.
Two types of endpoints are used in the Camel route, namely 'from' and 'to'.
- the 'from' endpoint is preconfigured in FEJ and must be the following: "<from uri="direct:routingRule"/>". It is used by the Camel destination endpoint for sending messages handled in Groovy rules.
- 'to' endpoints can be as many as required. They are implemented in Camel and can be found in the official Camel documentation.
The configuration is located in the sysconf/fej-camel-context.xml file and has the following structure:
| Code Block | ||
|---|---|---|

<beans xmlns="http://www.springframework.org/schema/beans"
