New Features in 5.1

In the 5.1.x release of Apache ActiveMQ there are the following new features:

Getting the Binary Distributions

Description Download Link PGP Signature file of download
Windows Distribution apache-activemq-5.1.0-bin.zip (no Safari) apache-activemq-5.1.0-bin.zip.asc
Unix/Linux/Cygwin Distribution apache-activemq-5.1.0-bin.tar.gz (no Safari) apache-activemq-5.1.0-bin.tar.gz.asc
Do not use Safari to download, the above URLs use redirection

The above URLs use the Apache Mirror system to redirect you to a suitable mirror for your download. Some users have experienced issues with some versions of browsers (e.g. some Safari browsers). If the download doesn't seem to work for you from the above URL then try using FireFox

Error When Expanding Tarballs

When expanding the binary tarballs you might wind up experiencing the following: 

$ tar zxvf /path/to/apache-activemq-5.1.0-bin.tar.gz
apache-activemq-5.1.0/bin/run.jar
apache-activemq-5.1.0/activemq-all-5.1.0.jar
...
apache-activemq-5.1.0/webapps/fileserver/WEB-INF/web.xml
apache-activemq-5.1.0/webapps/fileserver/WEB-INF/classes/org/apache/activemq/util/FilenameGuardFilter.class
apache-activemq-5.1.0/webapps/fileserver/WEB-INF/classes/org/apache/activemq/util/FilenameGuardFilter$GuardedHttpServletRequest.class
apache-activemq-5.1.0/webapps/fileserver/WEB-INF/classes/org/apache/activemq/util/RestFilter.class
tar: Unexpected EOF in archive
tar: A lone zero block at 61740
tar: Error exit delayed from previous errors

These errors are a product of an open bug in Maven and are innocuous and won't affect anything.

Getting the Binaries using Maven 2

To use this release in your maven project, the proper dependency configuration that you should use in your Maven POM is:

<dependency>
  <groupId>org.apache.activemq</groupId>
  <artifactId>activemq-core</artifactId>
  <version>5.1.0</version>
</dependency>
