AS2 - XML and Maven Support - Mule 4

If you manually code a Mule app in XML either from the Anypoint Studio XML editor or from a text editor, you can get access to the <connector> in your app by adding reference statements to your XML Mule flow and in the Apache Maven pom.xml file.

You can avoid the manual process described here by using Studio. When you install the AS2 Connector in Anypoint Studio, Studio automatically populates the XML code with the AS2 Connector namespace and schema location, and adds a dependency to the pom.xml file.

Add a Namespace for the Connector

Paste the following code inside the mule tag of the header of your configuration XML:

http://www.mulesoft.org/schema/mule/as2-mule4
http://www.mulesoft.org/schema/mule/as2/current/mule-as2-mule4.xsd

This example shows how the namespace statements are placed in the XML:

[source,xml,linenums]
<mule xmlns:http="http://www.mulesoft.org/schema/mule/http"
xmlns:as2="http://www.mulesoft.org/schema/mule/as2-mule4"
xmlns="http://www.mulesoft.org/schema/mule/core"
xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
	xmlns:spring="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	    xsi:schemaLocation="http://www.springframework.org/schema/beans
	    http://www.springframework.org/schema/beans/spring-beans-current.xsd
        http://www.mulesoft.org/schema/mule/core
	http://www.mulesoft.org/schema/mule/core/current/mule.xsd
        http://www.mulesoft.org/schema/mule/as2-mule4
	http://www.mulesoft.org/schema/mule/as2/current/mule-as2-mule4.xsd">
      <!-- put your global configuration elements and flows here -->
</mule>

Add a POM File Dependency

The pom.xml Maven file generated by Anypoint Studio contains dependencies for a Mule app. When you code a Mule app manually, include this XML snippet in your pom.xml file to enable access to the connector. The Mule runtime engine translates the RELEASE dependency keyword to the current version.

<dependency>
  <groupId>com.mulesoft.connectors</groupId>
  <artifactId>mule-as2-connector</artifactId>
  <version>5.1.0</version>
  <classifier>mule-plugin</classifier>
</dependency>

To obtain the most up-to-date pom.xml file information, access the connector in Exchange and click Dependency Snippets.
