Hi,
I have a servlet/jsp application running on tomcat 7.0.47. There are no
static html files.
Now I am try to use apache 2.4.7 (Ubuntu)
as the front and forward eveything to tomcat. I installed mod_jk using
Ubuntu's software
center.. Things are working. But I have errors in
/var/log/apache2/mod_jk.log:

If I add the following lines, the errors go away:
worker.list=jk-status
worker.jk-status.type=status
worker.jk-status.read_only=true
worker.list=jk-manager
worker.jk-manager.type=status
But the added line read funny. The same thing appears on the left-side of
the equal sign twice.
Are they correct? Do I need these lines? Can I ignore the errors?
Any information would be appreciated. Thanks in advance.
In addition to André's excellent tutorial: mod_jk knows that some
properties configured via workers.properties take (comma-separated)
lists as values. Since sometimes maintaining these lists is error-prone,
it allows you to define the properties multiple times and will collect
all given values into one big list. That makes maintaining hte list a
more modular job.
In your case the following is exactly equivalent:
Either:
worker.list=jk-status,jk-manager,myworker
Or:
worker.list=jk-status
#Some more config items concerning jk-status
worker.list=jk-manager
#Some more config items concerning jk-manager
worker.list=myworker
#Some more config items concerning myworker
In both cases the internal value of worker.list after parsing the
complete file will be "jk-status,jk-manager,myworker".
So what look a bit funny to you was supposed to be helpful ;)
Can you ignore the errors: No.
- If you don't want the jk-status and/or jk-manager worker features,
then look for the JkMount directives where you referenced them (or
entried in a uriworkermap.properties file but that's rarely used).
- If you want to use the jk-status and/or jk-manager workers, you need
to define them in workers.properties like you did above.
