Configuration File "wrapper.conf"

The Java Service Wrapper uses a configuration file, typically named wrapper.conf, to manage its settings. For a complete list of all available settings, see the Configuration Properties Overview section.

NOTE

Before modifying your configuration file, we highly recommend reviewing the Summary of Integration Methods. Each integration guide provides a step-by-step breakdown of how to adapt the configuration properties for your application and chosen integration method.

Integration Method 1 - How to modify "wrapper.conf" (Windows, Linux / UNIX)
Integration Method 2 - How to modify "wrapper.conf" (Windows, Linux / UNIX)
Integration Method 4 - How to modify "wrapper.conf" (Windows, Linux / UNIX)

Example of Configuration File "wrapper.conf"

A default template of the configuration file named wrapper.conf.in is located in the Wrapper's src/conf directory. Please copy this file into your application's conf directory and rename it to wrapper.conf. Then, modify the configuration to integrate your application.

Below is the default wrapper.conf.in template file for the latest release. It uses tokens (wrapped in @ symbols) that you should replace with your application's actual details during installation:

'@app.name@': A short identifier (e.g., testwrapper).
'@app.long.name@': The full name of your app (e.g., TestWrapper Application).
'@app.description@': A brief sentence describing your service.

NOTE

The template only contains default configurations used in most common scenarios. For more advanced use cases, a wide range of additional settings can be found in the Advanced Configuration Properties section.

Full template content:

@encoding=UTF-8
# The configuration file must begin with a line declaring its encoding.

# Default mode for file inclusions
@include.default_mode=required

# Include file problems can be debugged by removing '#' at the beginning
#  of the following line:
#@include.debug

# Wrapper License Properties (Ignored by Community Edition)
#********************************************************************
# Professional and Standard Editions of the Wrapper require a valid
#  License Key to start.  Licenses can be purchased or a trial license
#  requested on the following pages:
# https://wrapper.tanukisoftware.com/purchase
# https://wrapper.tanukisoftware.com/trial

# The Wrapper will look for either of the following optional files for a
#  valid License Key.  License Key properties can optionally be included
#  directly in this configuration file.
@include.optional ../conf/wrapper-license.conf
@include.optional ../conf/wrapper-license-%WRAPPER_HOST_NAME%.conf
