Chapter 14. 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 KIE 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"/>
KIE Server
In this scenario, the kie-camel component connects to KIE Server using the KIE Server REST API. This enables users to communicate with KIE Server using the KIE 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:
| Header | Description |
|---|---|
|
| KIE Server client (mandatory) |
|
| KIE Server client (mandatory) |
|
| The value of the client method parameter (optional) |
|
| The method parameter where the message body is stored (optional) |
