With the improvements
made to simplify Mule 4,
we’ve been able to reduce
our developer on-ramp
time...It’s now very easy to
make components of the
Mule applications reusable
and share them with other
developers, both in and out
of our organization.

What’s New in Mule 4
Raveendar Bandaru
Manager – Technical Success (WHISHWORKS)

31. All contents © MuleSoft Inc.
What’s new in Mule 4 - Overview
31
• Self tuning – No explicit knowledge of Processing strategies, threading profiles etc.,
default non-blocking with throughput
• Class loader isolation for runtime, application and connectors
• Everything is DataWeave now - We write DataWeave expressions inside #[]
• Every component has target removing need for enrich
• Improved exception handling: try scope, propagate
• Exchange is formal way building reusable assets
• More intelligent components – can automatically handle types
• Http Connectors from RAML
• Need to use Spring module explicitly to use spring beans
• Most commonly used connectors that have been upgraded – Database, File and FTP,
JMS, VM
• Single approach to extending mule 4

32. All contents © MuleSoft Inc.
DataWeave 2.0
32
• Mule 4 brings several improvements to DataWeave with 2.0
– Imports and modules
• Package and import scripts into other projects, enabling you to reuse and share
– Java interoperability
• Static methods can be executed through DataWeave
– New data formats
• Added text/plain, application/x-www-form-urlencoded, and multipart support
– Type system
• Indicate the type for functions and variables with type inference
– Simplified syntax
• Everything is a function and if/else clause is now the norm

Changes from MEL to DataWeave 2.0
33
Mule Expression Language DataWeave 2.0
#[flowVars.name]
#[sessionVars.id]
#[recordVars.recordid]
#[vars.name]
Session, Record variables are removed
#[message.inboundProperties.’http.query.para
ms’.name]
#[attributes.queryParams.name]
exception replaced by error
message.inboundAttachments and
message.outboundAttachments
The affected connectors now handle the
attachments (HTTP, EMAIL, WSC)
message.id, message.rootId and
message.replyTo
? function
server.dateTime now() function

Changes from MEL to DataWeave 2.0 (Contd…)

• DataWeave Selectors to query data, which doesn’t need extra
transformations when dealing with types like JSON

Migrating Mule 3 Connectors to
Mule 4
Ravi Kumar Gunda
Technical Architect - WHISHWORKS

38. All contents © MuleSoft Inc.
Mule 4 SDK
38
• Anypoint Connector DevKit is
replaced by Mule 4 SDK
• Facilitates faster development of
Mule modules, e.g. Connectors,
than its predecessor, Anypoint
Connector DevKit
• Decouples modules from the Mule
Runtime internals
• Mule SDK is not a code generator
• Compared to Anypoint Connector
DevKit, it is more powerful and
supports more features

39. All contents © MuleSoft Inc.
Mule 4 SDK (Contd…)
39
• Single way to
extend Mule
• Enforces
common UX &
best practices
• Annotation
based
• Transaction
Support
• Stateful
operations

40. All contents © MuleSoft Inc.
Mule Module Model
40
• The entry point for building a Mule module is the @Extension
annotated class

41. All contents © MuleSoft Inc.
Migrating Connector
41
• MuleSoft’s DevKit Migration Tool (DMT) assists on Connector
Migration
• DMT generates new code, compatible with Mule 4 SDK, wrapping the
Mule 3 connector code
• MuleSoft’s Recommendations
– Do not access the MuleContext
– An operation should have 1st param as Configuration object and 2nd param as
Connection object
– Exception classes should end with Exception
• New Module structure
– /api (exported classes)
– /internal (non-exported classes)
• operation, config, connection, error

42. All contents © MuleSoft Inc.
Migrating Connector (Contd…)
42
• Running DMT
– Changes to pom.xml:
<parent>
<groupId>org.mule.tools.dmt</groupId>
<artifactId>mule-dmt</artifactId>
<version>1.0.0</version>
</parent>
– mvn clean package
– Generated code @ target/generated_sources/extension
• Manually fix the compilation errors of the code generated
– Update pom.xml for any dependency libraries, due to change in parent
– Remove/Replace the packages/classes which doesn’t exist in Mule 4 SDK
• eg. org.mule.api.context.MuleContextAware to org.mule.runtime.core.api.context.MuleContextAware
• Refactor the code as per the new module structure and conventions
