Reading sling:OsgiConfig into @ObjectClassDefinition

[Adilmo]

We have a OSGI Service (using R7 DS annotation). We are using OCD as innerclass within the service.

Also, we would like the component to read properties from the predefined sling:osgiconfig nodes in JCR.

Configuration policy is defined as required.

When the component/service load it goes into a "no config" state.

Need help to read these configs from sling:osgiConfig nodes.

@Adilmo  Can you go to /system/console/components or /system/console/configuration and see if you are able to see your service class? If yes try to click/open and see what is the PID it is populating..

Even you can fill the configuration from osgi console once, copy the content to your local config file and then delete the file

component is not starting ... it is in "no config" state .... I would like to the component to fetch SLING CONFIG and start on its own .... no manual configuration through console

[Adilmo]

The component remains in "no config" state even though there is sling:osgiconfig for the corresponding PID present in JCR ... kindly help

Why do you want to read sling:OsgiConfig values inside OCD?

OCD is used to declare the OSGi config structure.

You can declare OCD the same as config values but in the end, the value will be read from the defined value in repository.

Example

https://github.com/arunpatidar02/aem63app-repo/blob/master/java/SimpleScheduledTask.java

[Adilmo]

Our problem is that we want to load the configuration values from sling:osgiconfig and not add them manually to through console.

[Adilmo]

Could you please provide any method to debug this? We have sling:osgiconfig under the /apps/*/config folder but component never recognize these properties. Please note that when we explicitly open the config, it populates with the sling:osgiconfig correctly and when we save it gets bound. Problem only happens when the bundle starts up, at that point component never finds the config and goes into "no config" state. Please advise and help

[arunpatidar]

probably you should check activate and modified annotations

@activate
@Modified
    protected void activate(final Config config) {
        myParameter = config.myParameter();
    }

Other example you can find on https://github.com/adobe/aem-guides-wknd/blob/archetype-18.1/ui.apps/src/main/content/jcr_root/apps/...

We have kept OCD as blank ... and we expecting we shall get sling:OSGIconfig values in our component .. but component always gets blank OCD....

[Adilmo]

We have environment specific sling:osgiconfig values and we want component OCD to populate from them. But on component activation we always get blank OCD.

[Adilmo]

is there a way we can achieve this in OSGI r7 annotation

[arunpatidar]

It should work as component is calling activate method when component is geeting activated and when value is modifed. Did you try restarting component just to check if issue is with first time deployment?

[Adilmo]

is there a way to dump configadmin ??

[Adilmo]

In your SimpleScheduledTask.java .... can you load properties from sling:osgiconfig ?? if yes can you share your config package as well ??

[arunpatidar]

hi, You can check examples from https://github.com/Adobe-Consulting-Services/acs-aem-commons/tree/master/ui.apps/src/main/content/jc...

I don't have any now but I will setup a package and share with you.

[Adilmo]

ok ... these are config files rather xml for sling:osgiconfig

[Adilmo]

is there a difference between config files and sling:osgiconfig when dealing with configadmin

[arunpatidar]

Here is the example https://github.com/arunpatidar02/aem63app-repo/tree/master/java/page/json

[arunpatidar]

config files are created when you update osgi config from web console

[Adilmo]

just one question when you start the bundle without configuring the component through webconsole, do you get your xml configured properties in this method public void activate(PageJSONServletConfig config) { excludeProperties=config.exclude_properties(); refrenceProperties = config.refrence_properties(); renameProperties = config.rename_properties(); limit= config.limit(); }
