New Features in 5.1

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

Getting the Binary Distributions


Download Link

PGP Signature file of download

Windows Distribution

Unix/Linux/Cygwin Distribution



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

Verify the Integrity of Downloads

It is essential that you verify the integrity of the downloaded files using the PGP or MD5 signatures. The PGP signatures can be verified using PGP or GPG. Begin by following these steps:

  1. Download the KEYS
  2. Download the asc signature file for the relevant distribution
  3. Verify the signatures using the following commands, depending on your use of PGP or GPG:

    $ pgpk -a KEYS
    $ pgpv apache-activemq-<version>-bin.tar.gz.asc


    $ pgp -ka KEYS
    $ pgp apache-activemq-<version>-bin.tar.gz.asc


    $ gpg --import KEYS
    $ gpg --verify apache-activemq-<version>-bin.tar.gz.asc

(Where <version> is replaced with the actual version, e.g., 5.1.0, 5.2.0, etc.).

Alternatively, you can verify the MD5 signature on the files. A Unix program called md5 or md5sum is included in most Linux and Unix distributions. It is also available as part of GNU Textutils. Windows users can utilize any of the following md5 programs:

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
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.
