What's New in Mule Enterprise Version 2.1

Mule Enterprise Version 2.1 includes Mule Enterprise Edition 2.1.3 and Mule HQ 3.5.0. This page describes the major new and changed functionality, the issues that have been fixed, and known issues in this release.

Mule 2.1 is an older release. For information on what's new in the latest release of Mule, see What's New in This Release.

New Features

This section describes the new features exclusive to Mule Enterprise Version 2.1. Note that this release also includes all the new features in Mule Community Edition Versions 2.0 through 2.1.2, such as the powerful new configuration based on XML schemas. For more information, see What's New in Mule 2.0.

Migration Tool

The principal new feature of Mule Community Edition 2.0 was a powerful new schema-based configuration style leveraging Spring's Extensible XML Authoring. This approach makes configuration much simpler. In Mule 2.1 Enterprise Edition, you can use a migration tool to help convert your existing Mule 1.x configuration files to the Mule 2.1 format. For complete information, see the Migration Tool on the Mule Customer Portal.

For more information on the new configuration format, see [XML Configuration]. For more information on what changed from Mule 1.x to Mule 2.x, see Migrating Mule 1.x to 2.0, Migrating Mule 2.0 to 2.1, and Migrating Mule 2.1 to 2.1.2.

Retry Policies

Retry policies configure how a connector behaves when its connection fails. Retry policies were implemented in Mule 2.1 CE to replace reconnection strategies. Mule 2.1 EE includes several standard retry policies available that you can configure using the Retry schema.

For more information, see [Configuring Retry Policies].

Official Support for the RESTpack

The Mule RESTpack is now officially supported as part of Mule Enterprise 2.1. For more information, see [Using the Mule RESTpack].

Improvements to Mule HQ

Mule Enterprise Version 2.1 includes Mule HQ 3.5.0, which provides improvements to Mule HQ including bug fixes (see Fixed Issues below) and performance enhancements.

Improvements to JDBC Transport

The Premium JDBC transport includes much faster performance and now provides batch and cursor support. For more information, see JDBC Transport.

CXF Transport Support for XML Input

Previously, the CXF transport took JAXB POJOs as the web service payload, requiring transformation to JAXB. Now, the CXF transport can handle XML payloads without transformation. For more information, see CXF Transport.

Extended QA Certification

The MuleSource Quality Assurance team has extended its certification of Mule, ensuring that the product is of greater quality than ever before. For a list of certified platforms, see Supported Platforms.

Known Issues

This section describes the major known issues in this release and how to work around each issue.

• In Mule EE 2.1.3, if you want to run the Webapp example using Maven, you must first modify its POM file and add the following dependency:

  <dependency>
    <groupId>org.mule.transports</groupId>
    <artifactId>mule-transport-cxf</artifactId>
    <version>${muleVersion}</version>
    <exclusions>
      <exclusion>
        <groupId>org.apache.ws.security</groupId>
        <artifactId>wss4j.osgi</artifactId>
      </exclusion>
    </exclusions>
  </dependency>
  

• If you are experiencing agent-server communication problems with Mule HQ, upgrade to JRE 1.5 or 1.6 by setting the environment variable HQ_JAVA_HOME for MuleHQ agent and server.
• In Mule HQ, if a configuration file cannot be found or the wrong user ID or password are used to access JMX, the error message simply says "Mule Enterprise Edition is already running."

Mule Enterprise Version 2.1 includes many new features and fixes developed on Mule Community Edition as well as Mule Enterprise Edition. For a list of the Community fixes, see Mule Community Version 2.1.2.
