[Configuration] load config files from ddifferent jars
Hello,
I would like to set up a configuration factory specifying a properties
file which does not reside in the same jar as the composite
configuration .xml file.
Example:
<configuration>
<properties fileName="application.properties"/>
<properties fileName="/biz/prop.properties"/>
<hierarchicalDom4j fileName="objects/business-objects.xml"/>
</configuration>
It appears that the leading slash is stripped and an attempt is made to
read biz/prop.properties from the .jar file where above .xml config
resides.
I notice there is a setBasePath() which would probably solve the problem
if all composite config files resides below the same basepath. But in my
case the various config files reside in different jar files.
Is there a way of loading the various config files from different .jar
files?

Could you maybe submit a unit test? Basically, create a stripeed down jar,
and put in in /conf. Also submit a generic ConfigurationFactory settings.
Open a bug in bugzilla and attach this. That way we can track and not lose
this example.

Re: [Configuration] load config files from ddifferent jars
Posted by T E Schmitz <ma...@numerixtechnology.de>.
Hallo Oliver,
Thanks for your response.
I tested this on Windoze 2000 but the application will eventually run on
Linux. But this shouldn't come into it as the properties file resides in
another jar file (see example below).
The jar containing the properties file is called biz.jar and the
properties file is in the root package "biz". Hence I tried to refer to
the prop file as "/biz/prop.properties". The jar containing the
composite config .xml is called app.jar. Both jar files are in the
classpath of the application.
I certainly do not want to have to specify the other jar file using an
absolute file name.
I got the following exception which shows that the ConfigurationFactory
is trying to load biz/properties, i.e. a file in the same jar as the
composite config .xml.
Here's a stack trace snippet.
Caused by: org.apache.commons.configuration.ConfigurationException:
Could not load from file /biz/prop.properties
at
org.apache.commons.configuration.PropertiesConfiguration.load(PropertiesConfiguration.java:107)

ConfigurationFactory should work with both relative and absolute file
names (at least this is the theory ;-) You should also be able to pass
in a complete URL.
Which operating system are you working on? If it is Unix/Linux, your
configuration file shouldn't make problems (unless there is a bug in the
methods for loading the configurations). Under Windows you will have to
provide a filename like C:\mydir\myproperties.properties. You can also
try to specify a file:/ URL pointing to your properties file.
Hope this helps!

Hello Eric,
I'd be happy to make some contributions in return for the excellent
libraries that Jakarta Commons is providing.
Once I have some time I'll have a look at it and familiarize myself with
your code conventions.
Best regards,
Tarlika

Humm.. Not sure on this one... It seems like what we should be doing is
actually loading them as a resources.. that way trying to find it is left
up to whaterver classloader is being used.. so, it shouldn't care what jar
it is in.. However, not quite sure how to do that.. patches welcome...!
I am sure you can do what you want, it seems not hard, but I'm not sure..
Worse comes to worse, skip the configurationfactory, and just do it
yourself.. but it would be nicer to just patch configurationFactory.
