This module provides an Apache Camel component and an Alfresco Repository component.
The change log for Alfstream can be found here
- Alfresco Dynamic Extensions 1.4.2 which you can download from here
- Java version 8
- Version 5.0 and Above
- Apache Karaf 4.0+
- The Alfstream Camel Component
We have created a plugin for gradle called the alfresco amp plugin which is a requirement for compiling all of our modules.
Installing the Alfresco Amp Plugin¶
Installing of the Alfresco amp plugin requires the following:
- Java JDK 7 or above installed
- Gradle installed
Cloning the repository¶
You can simply clone down our repository with your gitlab account:
git clone https://gitlab.parashift.com.au/open/alfresco-amp-plugin
Publishing to Local Maven¶
Once you have cloned the repository, it should be published into your gradle environment. This will by default publish to your local computer, but you can adjust build.gradle to publish to another Maven server if it's a requirement with:
- Parashift's AlfStream module is a Repo only amp, please follow our Installation guide on how to install this module.
- Alfresco Dynamic Extensions is required to be installed, please follow Dynamic Extension Installation guide on how to install it.

Installation of this module requires an instance of Apache Karaf to host Apache Camel.
Karaf is normally stored within the
/opt/apache-karaf-*/ directory where
* is the version number.
To install prerequisite software you will need to do the following:
- Download and install the latest version of Java JDK (version 8): http://www.oracle.com/technetwork/java/javase/downloads/index.html
- Download and install Apache Karaf: http://karaf.apache.org/download.html
- Extract this to a directory such as
- Run the application in a terminal with
After this is done follow the
Apache Karaf Manually instructions below.
Apache Karaf via Salt Stack¶
Rather than manually instantiating Karaf, utilising Salt Stack will allow the configuration of Karaf to take less time and ensure that things are deployed in the right order.
- Create the following pillar configuration on the server:
karaf: bundles: - mvn:org.apache.commons/commons-lang3/3.4 - mvn:com.google.code.gson/gson/2.6.2 - mvn:org.yaml/snakeyaml/1.17 artifacts: - alfstream-1.*.*.jar
- Run the following state command:
salt-call state.sls karaf
Apache Karaf Manually¶
- Install Apache Karaf as per the website instructions or windows install instructions above
- Copy this file and put it in the karaf base directory, naming it
feature:repo-add camel 2.17.0 feature:repo-add hawtio 1.4.64 feature:install camel feature:install camel-core feature:install camel-blueprint feature:install hawtio bundle:install mvn:org.apache.commons/commons-lang3/3.4 bundle:install mvn:com.google.code.gson/gson/2.6.2 bundle:install mvn:org.yaml/snakeyaml/1.17 bundle:install mvn:org.apache.httpcomponents/httpclient-osgi/4.5.2 bundle:install mvn:org.apache.httpcomponents/httpcore-osgi/4.4.4
- Linux: Log in to the cli by running
- Windows: Make sure you have an instance running by executing:
- Run the command
source bundlesin the client to install all the bundles
- Copy and deploy the following files to the
To monitor that everything is going OK, you can utilise the web console
hawtio via the following URL:
Camel tab of hawtio, you can see deployed routes that are in Apache Karaf.
Warning: To trace an exchange, You must first disable Inclusion of Streams in the trace output. This is because viewing a file while tracing will consume the stream, not allowing it to be uploaded to Alfresco.
In the top right click on
karaf then click
Include Streams checkbox.
Include Streams is unselected, click on one of the routes and select the
Trace tab. Then select
Start tracing. This will enable all exchanges passing through the route so that you can see the inputs/outputs.
The logs are accessible via the
Logs tab. By default the Log Level of
INFO is set, so you may need to adjust this to include
DEBUG level routes using the CLI
bin/clientfrom the karaf directory (normally
- (Optional) increase the log to include debug logging for parashift packages:
log:set DEBUG com.parashift
log:tailto view the log
You will see debug logs from the
com.parashift namespace, which will include the alfstream components.
There are a few usage examples within the examples directory.
Setting up Configuration variables¶
All examples make use of configuration variables external to the blueprint file. To create these configurations:
- Create a new file:
alfstream.url=http://localhost:8080/alfresco alfstream.username=admin alfstream.password=admin
After you have set up the configuration variables, simply drop the blueprint xml file in the karaf
deploy directory to start the route.
Debug Log Example¶
The debug log example simply logs all exchanges to a debug log.
You will need a log level set to debug within karaf:
log:set debug com.parashift
Two Way Blueprint¶
Alfstream Sync is used to provide two way syncing between Alfresco instances.
Requires the upsert camel component. This will allow alfstream events to be synchronised to a seperate postgres database for reporting and analytics.
