Re: Connecting from SAP XI to ActiveMQ
Hi,
We have a SAP PI 7.1, with JAVA 1.5 and when uploading the latest driver
version of ActiveMQ, we get the following error:
Error while starting channel: org/apache/activemq/ActiveMQConnectionFactory
has been compiled by a more recent version of the Java Runtime (class file
version 52.0), this version of the Java Runtime only recognizes class file
versions up to 49.0
@ ActiveMQ / Forum: Please, can you provide me with a driver version that is
compatible with the JAVA version or some other solution?
Thanks, Regards,
Jose

Hi,
The JAVA update is not recommended, for the version we have of SAP PI 7.1
and for that reason I have contacted the forum.
Thanks!!

Jose

To add to Justin's points, that old JRE is forcing you to use an old
version of ActiveMQ, for which many bugs were later fixed. Upgrade to a
more modern JRE (probably Java 8, unless SAP PI 7.1 supports Java 9+, but
that certainly isn't guaranteed given that it was released in 2008), and
then upgrade to a recent version of ActiveMQ.

Check out the documentation [1]. In short, ActiveMQ 5.7 looks to be the
last version that supports Java 5 (JDK 1.5) so you'll need to use a client
from that version. I would expect later releases of the broker to be
backwards compatible with older clients.
Aside from that, I recommend you move to a later version of Java. According
to Wikipedia [2] public support and security updates for Java 1.5 ended in
November 2009. Paid security updates for Oracle customers ended in April
2015. You're using a really old platform at this point which is both a
support and security risk.
