Lessons and Topics

Accessing and modifying Mule events

• Log event data
• Debug Mule applications
• Read and write event properties
• Write expressions with the DataWeave expression language
• Create variables

Structuring Mule applications

• Create applications composed of multiple flows and subflows
• Pass events between flows using asynchronous queues
• Encapsulate global elements in separate configuration files
• Specify application properties in a separate properties file and use them in the application
• Describe the purpose of each file and folder in a Mule project
• Define and manage application metadata

Consuming web services

• Consume web services that have an API (and connector) in Anypoint Exchange
• Consume RESTful web services
• Consume SOAP web services
• Pass parameters to SOAP web services using the Transform Message component
• Transform data from multiple services to a canonical format

Controlling event flow

• Multicast event
• Route events based on conditions
• Validate events

Handling errors

• Handle messaging errors at the application, flow, and processor level
• Handle different types of errors, including custom errors
• Use different error scopes to either handle an error and continue execution of the parent flow or propagate an error to the parent flow
• Set the success and error response settings for an HTTP Listener
• Set reconnection strategies for system errors

Writing DataWeave transformations

• Write DataWeave expressions for basic XML, JSON, and Java transformations
• Write DataWeave transformations for complex data structures with repeated elements
• Define and use global and local variables and functions
• Use DataWeave functions
• Coerce and format strings, numbers, and dates
• Define and use custom data types
• Call Mule flows from DataWeave expressions
• Store DataWeave scripts in external files

Triggering flows

• Read and write files
• Trigger flows when files are added, created, or updated
• Trigger flows when new records are added to a database table
• Schedule flows to run at a certain time or frequency
• Persist and share data in flows using the Object Store
• Publish and consume JMS messages

Processing records

• Process items in a collection using the For Each scope
• Process records using the Batch Job scope
• Use filtering and aggregation in a batch step

Migrating Mule 3 applications

• Migrate a Mule 3 application using Mule Migration Assistant (MMA)
• Describe the scope and limitations of MMA
• Read and understand MMA migration reports
• Refactor a migrated application to make best use of Mule 4 features

Setup requirements
