contribution: configurable OFBiz configuration :-)
Hi all,
we have changed the OFBiz configuration mechanism for our latest projects
and I think this change could be useful also for the OFBiz standard.
The problem:
Our customers often have several server systems for one project, at least
a development, a test and a production server. Some of them have even
more, up to five systems.
All servers have different IP addresses, sometimes different port
settings, different cache settings etc. This is hard to handle and it is
error-prone to edit the configuration sets for every system after the
project is checked out to the target server. Additionally it would be more
convenient to edit the settings at a central place instead of many
different files in the project.
So we thought about a more elegant solution for it.
The solution:
The solution is simple and implemented with the tools the project already
contains: Ant and some template configuration files.
We have moved all necessary configuration files from their origin to a
special folder called templates and removed the values from them. The
values are written in a separate build.properties file. A new Ant target
creates the target configuration files from the templates an the
build.properties file and copies them to the original location. These
files are in the svn ignore list so that they are not checked in by
accident.
For every system we have additional property files like test.properties,
live.properties etc. If we want a configuration other than the default
from build.properties, the ant configuration target ist executed with the
corresponding machine name (e.g. ant -Dmachine.name=live build.xml
configure-and-build). These files only contain the changes from the build
properties file.
If a property file local.properties exists, it will be processed after
build.properties to have a local developers configuration available.
The following changes have to be made:
1. create a new folder configure and the folders templates and properties
under it
2. create the configuration templates and corresponding build.properties
file from the original configuration files
3. delete the original files after adding them to svn:ignore to avoid
checking them back in
4. create a new build file in the configure folder to do the
configuration.
5. add a new configuration target to the main build file
This is a simple but powerful solution and we are quite happy with it. We
would like to contribute this solution as a patch if you find it as useful
as we do.
I appreciate your feedback!

Hi Michael,
This system exist on Neogia project with config directory. At the root
of the project, we put a site.properties that read all config files on
the site directory.
I think, we can contribut all idea to ofbiz projet, if you want ;)

I agree that having a data model would be better. But still, an hour or
two of coding and we could have configuration screens for the existing
properties.

I would really like to not see this happen, as it would only be a
slight improvement over what exists now, but it wouldn't be a real
data model and the result would be as disorganized and difficult to
understand and use as the current flat properties file. I guess it's
not too bad, but we don't have to stick to a single flat list of
properties in the database... we have a lot more flexibility there.
Anyway, the data modeling and queries and UIs should be a vast
improvement over what exists now, and I'm thinking well worth the
effort as well.

I was thinking we could add a bit of code to the UtilProperties class
that would check a common entity in addition to properties files. It
would be a simple change to make, and applications could still get their
settings through UtilProperties.getProperty(...) method calls. Screens
could be created to manage groups of properties.

No one has gone through a modeling exercise yet, so I don't know
exactly what the entities would look like. In essence the each
property in the relevant properties files needs to be considered and
added where it makes the most sense, either to existing entities or
new ones. For payment.properties most of the information would go in
the ProductStorePaymentSetting entity or in entity(ies) related to it.
They would replace the
ProductStorePaymentSetting.paymentPropertiesPath field which is
currently used to refer to a payment.properties file (of a different
name, ie allowing multiple files for multiple payment processors... a
"hack" if you will).

No one has gone through a modeling exercise yet, so I don't know
exactly what the entities would look like. In essence the each
property in the relevant properties files needs to be considered and
added where it makes the most sense, either to existing entities or

An interesting idea. Would a single entity be used for that, or would
each application have its own entity?
-Adrian
Re: contribution: configurable OFBiz configuration :-)
Posted by David E Jones <jo...@hotwaxmedia.com>.
This has been discussed before and decided against.
An easier solution would be to just put all of the configuration
properties in a single file, except that:
1. different components need different configuration and we don't want
to assume in this way which components or combinations of them will be
used
2. the file would become enormous unless we trim down available
configuration options, and doing that effectively would require
knowing more or less exactly what the system is to be used for (ie
limit the scope and exclude part of the current OFBiz user base)
What we do at Hotwax, and I think what most do (though I don't know)
is create a patch for each server if differences between the servers
are needed. However, in the common case of a pool of servers running
together to create a large instance of OFBiz these per-server
configurations are generally not needed because all of the URLs that
need to be configured are the external/outside URLs that hit the load
balancer, and those are the same for all instances in the pool.
On side note I should mention that the direction has been discussed
and generally agreed on that application level properties should be
done away with (like payment.properties, and many others) and that
information should go into the database. The main reason behind that
is to support differing initial data for common setups that can simply
be loaded into the system when it is run and you can get started
quickly and without having to dive into files... oh and also that you
can maintain things through a UI instead of through editing properties
files.
