How can I forward message from a specific log file like /www/myapp/log/test.log with rsyslog client to remote rsyslog server? This log file is outside of the directory /var/log.

Just setup an imfile rule in your /etc/rsyslog.conf

#/etc/rsyslog.conf
$ModLoad imfile
$InputFileName /data/mysql/error.log
$InputFileTag mysql-error
$InputFileStateFile stat-mysql-error
$InputFileSeverity error
$InputFileFacility local3
$InputRunFileMonitor
local3.* @@hostname:<portnumber>

This watches a file and saves to the local3 facility in syslog. Then you can send all data from the local3 facility to your remote server. You may also want to add the following to your rsyslog conf (usually /etc/rsyslog.d/50-default.conf on Ubuntu) to not save the local3 facility to /var/log/syslog:

#/etc/rsyslog.d/50-default.conf
*.*;auth,authpriv.none,local1.none,local2.none,local3.none,local4.none,local5.none,local6.none          -/var/log/syslog

Additionally, I would encourage some reading from the following rsyslog docs for more advanced filtering:
