Re: [Wrapper-user] Question about wrapper configuration files

[Leif M. <le...@ta...>]

Merri,
The Wrapper is not able to read the values from your ini file.  But it
will work off of a master configuration file.  You may be able to do
something where you generate a wrapper-master.conf file with the
values in your ini file to avoid having to make changes in two places.

wrapper-master.conf:
---
set.JRE_PATH=C:/jre/bin/java.exe
set.PROP_1=C:/some_path/to_some_file
set.PROP_2=C:/another_path/1.0
---

wrapper.conf:
---
#include ../conf/wrapper-master.conf
wrapper.java.command=%JRE_PATH%
wrapper.java.classpath.1=%PROP_2%/wrapper.jar
wrapper.java.classpath.2=%PROP_2%/xyz.jar
wrapper.java.additional.1=-Dcom.testing.value=%PROP_1%/abc/xyz
---

Cheers,
Leif

We have an ini formatted file that drives the generic launcher where we list the java location, the command line arguments, and the working directory.  We also use the Service Wrapper to start some of these applications as a service.

Basically, it's a file that contains a list of variables and their values (they are mostly paths) that we can then reference by variable name in the ini files for each of the app launchers.  This creates a kind of lookthrough so that our customers are able to update the value of a common variable in the master config file without having to go and update each individual application ini file.

I have read the information about the cascading configuration files, but I'm not sure if the options have to match exactly in the included file.  Our options do not match, so I'm trying to see if there is a way to make this work without having to make code changes.  I've included a sample of what I am looking to do is below.
