> Key: KARAF-4361
> URL: https://issues.apache.org/jira/browse/KARAF-4361
> Project: Karaf
> Issue Type: Improvement
> Components: karaf-core
> Affects Versions: 4.1.0, 4.0.4
> Reporter: Serge Huber
> Assignee: Jean-Baptiste Onofré
> Fix For: 4.1.0, 4.0.8
>
> Attachments:
> KARAF_4361_Allow_dynamic_config_customization_when_embedding_Karaf_using_the_Main_class.patch
>
>
> We are using Karaf by embedding it and basically starting it like this :
> {code}
> // code to setup System properties
> main = new Main(new String[0]);
> main.launch();
> {code}
> The problem is that the ConfigProperties that are used to startup Karaf are
> directly created in the main.launch() method, like this:
> {code}
> public void launch() throws Exception {
> config = new ConfigProperties();
> {code}
> Ideally it would be great if we could either have a setter to provide the
> config value, so that we could manipulate it before launching. In an embedded
> environment this quickly becomes a necessity. For example we would like to
> make it possible to have retrieve properties coming from another framework
> such as Spring and use those to override config.properties settings in a
> dynamic way, without needing to dump them to a file at Karaf startup. I'm
> aware of the ${includes} and ${optionals} but those require files to be read
> from the disk where here I'm talking about being able to dynamically
> manipulate the properties once loaded.
> Basically something like this would be fantastic
> {code}
> // code to setup System properties
> main = new Main(new String[0]);
> ConfigProperties config = main.getConfig();
> if (config == null) {
> config = new ConfigProperties();
> }
> // manipulate config in any way desired
> main.setConfig(config)
> main.launch();
> {code}
> The main.launch could then simply be modified to something like this :
> {code}
> public void launch() throws Exception {
> if (config == null) {
> config = new ConfigProperties();
> }
> {code}
> Btw we are using Karaf 4.0.x so having this in both Karaf 4.1.0 and Karaf 4.0
> would be fantastic.
