What evidence do you have that the task is triggered multiple times?
(I'm not saying I don't believe you, I'm just curious... it might help
determine WHY it's being run twice.)
We have an Ubuntu 14.04.1 Server using the standard tomcat 7
installed using apt-get and running on oracle java 8.
Ubuntu tends to be relatively up-to-date compared to other distros,
but do you know what version of Tomcat 7 you actually have? It won't
have anything to do with this problem, but upgrading to latest is
always recommended.
Tomcat is configured as a stand alone not a cluster and I had a
look at the servers.xml file and it only has one host.
It has to be the way we have tomcat configured, but I can¹t see
what. I changed from quartz to spring scheduling thinking the issue
was quartz, but that made no difference.
I¹d really appreciate any pointers at this stage.
At first, I was sure the issue would be multiple-deployment, triggered
by putting a <Context> element in your server.xml that pointed to a
WAR file (or exploded WAR directory) in your webapps/ folder. That
would do it. But you posted your server.xml elsewhere in this thread,
and that's not the problem.
But you might still have a double-deployment.
Do you have any files in CATALINA_BASE/conf/Catalina/localhost/? If
so, which ones and what do they contain?
What do you have in CATALINA_BASE/webapps/?
How do you launch Tomcat?
Also, if an application is being doubly-deployed, it should be visible in the Tomcat
logfile (at the beginning, when Tomcat starts).
