Chapter 4. The kie-camel component
The kie-camel component is an Apache Camel endpoint provided by Red Hat Fuse that integrates Fuse with Red Hat Process Automation Manager. It enables you to specify a Red Hat Process Automation Manager module by using a Maven group ID, artifact ID, and version (GAV) identifier which you can pull into the route and execute. It also enables you to specify portions of the message body as facts.You can use the kie-camel component with embedded engines or with Process Server.
Embedded engines
In this scenario, KIE engines run in the same container as the Fuse integration project and you can communicate with engines using KIE commands. To create the Camel producer, use the following URI:
kie-local:kie-session-name?action=execute
For example, enter the following command to initialize a Camel route in Spring:
<from uri="direct:runCommand" /> <to uri="kie-local:kie-session1?action=execute"/>
Process Server
In this scenario, the kie-camel component connects to Process Server using the Process Server REST API. This enables users to communicate with the Process Server using the Process Server API. To create a producer, use the following URI:
kie:http://username:password@kie-server-url`
For example, enter the following command to initialize a Camel route in Spring:
<from uri="direct:runCommand" /> <to uri="kie:http://user:psswd@localhost:8080/kie-server-services/services/rest/server"/>
The message has the following headers:
