So mod_proxy is loaded but you don't want to use it to access alfresco,
instead just mod_jk, right? Then don't use any ReWriteRule with the [P}
flag or any Proxy... directive.
OK as above, since commented, so not active.

Assume all static images, css, js are in some /path/to/my/folder/static
and there's nothing else underneath it, that folder would be a place to
publish directly via Alias in Apache.

I'm guessing here: what you want is that the request for
http://share.domain.com should be forwarded to the Tomcat web
application names "share".
For that I would put the following directives into the Apache
VirtualHost that actually serves the request.
- Add a redirect for the URI / to /share/ to the Apache config:
RedirectMatch ^/$ http://share.domain.com/share/
- Forward all requests that point below /share to Tomcat and let them be
served by the webapp:
JkMount /share|/* myworker
You can choose any name for "myworker", but see below for
workers.properties.
- Remove other JkMount, Alias etc.
At this step:
- do not try to serve static content from Apache, first get this to work
before adding the additional complexity.
- do not try to make the webapp /share/ directly available under the top
level directory. It is OK to redirect the a request for
http://share.domain.com/ to http://share.domain.com/share/ and proceed
from there as above, but it is harder to remove the "share" URI path
component from each request. If you really need to do this, then use
mod_proxy, not mod_jk.

Don't use this configuration. It is garbage.
Download a mod_jk source distribution (recent is version 1.2.37) which
contains a nive default workers.properties file. You can also get it here:
http://svn.apache.org/viewvc/tomcat/jk/trunk/conf/workers.properties?view=co
In that file, remove all lines referring to "node2" and replace "node1"
by whatever worker name you have chosen in JkMount (myworker or whatever).
Finally set "host" and "port" of that worker to whatever port and server
name your Tomcat listens to.

Your config directive
JkShmFile /var/log/alfresco/shm
has not worked. Check whether the directory /var/log/alfresco exists and
is writable.
If you can't solve this, you can set JkLogLevel to debug, which will
produce lots of startup and request handling output we can look at.
Are you using a relatively recent version of mod_jk (1.2.37)? Which
version of Apache are you using?
