File Folder Listener Example

Overview

Monitors a local folder for new files and submits to the JobConfig run API.

Listener Activation

Once you have created your DSL, drop it in the appropriate folder as routes.xml:

• Integration Manager: <ProgramDataDirectory>\Actian\IntegrationManager\camel\routes.xml
• Integration Agent: <ProgramDataDirectory>\Actian\IntegrationAgent\camel\routes.xml

note

Multiple routes (i.e., AWS, Azure, GCP, and Local) can be added into a single routes.xml.

Example DSL

(Copy and save as routes.xml)

<?xml version="1.0" encoding="UTF-8"?>
<routes xmlns="http://camel.apache.org/schema/spring">    
    <route id="run-jobconfig-with-local-file" autoStartup="true">

Configurable Properties

Property	Description	Default
route id	A unique identifier for the route configuration.
autoStartup	Prevents Camel starting the routes on startup.	false
jobConfigId	The job configuration Id in your Integration Manager. The jobConfigId in the above example is configured above with the constant value 102712 (<constant>102712</constant>)
recursive	If a directory, will look for files in all the sub-directories as well.	false
filterFile	Filters the file based on Simple language. For example, to filter on file size, you can use a $\{file:size} of 5000. In the above example, filterFile is configured with file that was modified over 14 days ago (i.e., ${file:modified} &lt; ${date:now-14d} ).
level	Logging level to use. In the above example, the log endpoint is configured to trash.	INFO
