Starting with Wrapper version 3.0.0,
it is possible to specify "include files" within a configuration file like cascading style.
This is useful where there is a need to override default values
without modifying the main default configuration file
"wrapper.conf".
Syntax:
Include files are specified by placing a line in the configuration file with the following syntax:
#include ../conf/wrapper2.conf
|
Layer Depth:
Include files can be nested up to 10 levels deep with cascading style.
Missing "include files"?:
If the specified file can not be found for any reason, then it is just ignored.
This makes it easy to specify a series of optional cascading configuration files
which users may or may not create yet.
Property Priority:
The order of where within a file you should put the definition of the include file is important.
If there are the same name of properties in the configuration files, you should pay attention to the order.
The definition of "#include" line should be placed
at the very bottom of the configuration file.
For example,
the "wrapper.conf" file includes "File2.conf"
and the "File2.conf" file includes "File3.conf".
In addition, the property "PropertyX=valueX" is defined in EACH of the three files.
In this case, the property value
"PropertyX=value3" of "File3.conf"
will be set after processing all files.
On the other example, properties set after the included file will override properties settings within the included files.
This rule applies to the all contents of include files as well.
Path:
If relative paths to the include files are specified,
be aware that all paths must be relative to the location of the Wrapper working directory.
By default, the working directory is the location
of the wrapper.exe file on Windows,
or of the script used to launch the Wrapper on Unix.
The working directory can be changed using the
wrapper.working.dir property,
but this does not take effect until after the full configuration file has been loaded.
This means that relative include file references will
always be relative to the original working directory of the Wrapper.

Enable Debug Messages :
Include files are designed to be optional so the Wrapper will silently skip the include file
if it can not be found.
This can make debugging problems involving include files frustrating.
To help with this, it is possible to enable debug messages about include files
using the following declaration "#include.debug"
before any #include file references.
Be aware that this debug declaration will have to be done
before your configured logging properties
have been processed in the configuration file "wrapper.conf".
Output:
The output will show up on the console as well as in the default
wrapper.log file,
which will be located in the same directory as the Wrapper binary.
If the Wrapper is being run as a Windows Service,
then the default wrapper.log will show up
in the Windows system32 directory.
