Question 1

Workflow step to move an asset
What was the problem?
Solution including APIs you used

Answer 1

The client required a workflow to move a pdf file to different locations in the DAM without any interaction. The pdf’s filename had underscore separated codes, which identified the destination folder for the file.

Solution:
Created a workflow that is launched when a file is created under /content/dam/mosaic
Go to Tools>Workflow>Model>create new model
Tools>Workflow>Launcher > create a launcher for when a file is created event
Add a Process step to the workflow model and select your custom process step.

Created a custom workflow step by implementing the granite WorkflowProcess class and implementing the execute method.
In the execute method I used the granite AssetManager api’s move method to move the asset from source to destination.

Custom replication agent to call Akamai and clear the cache

Replication in aem allows you to move content across servers.
To create a custom replication agent:

Replication Agent UI: copy the replication agent from cq/replication/components/agent

Implement Content builder: creates the content that will be sent in the body of the request by the transport handler. (Select as serialization type)

Implement Transport handler: handles communication with the server
Call akami using Apache http client.
