RE: Need help in implementing Sling Context Aware Configuration
you do not need org.apache.sling.caconfig.bnd-plugin as direct reference in
your - it's only useful as dependency for maven-bundle-plugin or other tooling
that used bnd to generate the OSGi SCR metadata, see [1] as an example.
but this should not be the source of your problem - did you deploy the bundles
org.apache.sling.caconfig.impl, org.apache.sling.caconfig.api,
org.apache.sling.caconfig.spi to your application instance, and are they
running (check OSGi console)?
if yes, can you give us the full stack trace?

RE: Need help in implementing Sling Context Aware Configuration
Hi All,
I managed to resolve the dependency issue by embedding these jars.
Now I am getting issue @ line 3
ResourceResolver resourceResolver = request.getResourceResolver();
Resource contentResource = (Resource)
resourceResolver.getResource("/content/ubi/test");
ValueMap props =
contentResource.adaptTo(ConfigurationBuilder.class).asValueMap();
com.adobe.beagle.servlet.ContextAwareConfigReader [Exception]
java.lang.NullPointerException: null
Any help is appreciated.
Regards,
Gopal

Subject: Need help in implementing Sling Context Aware Configuration
Hi,
I am looking to use Sling Context Aware Configuration.
https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configuration.html
I have added these in the POM file
org.apache.sling
org.apache.sling.caconfig.impl
1.0.0
org.apache.sling
org.apache.sling.caconfig.api
1.0.0
org.apache.sling
org.apache.sling.caconfig.spi
1.0.0
org.apache.sling
org.apache.sling.caconfig.bnd-plugin
1.0.0
Java code
ResourceResolver resourceResolver = request.getResourceResolver();
Resource contentResource = (Resource)
resourceResolver.getResource("/content/ubi/test");
ValueMap props =
contentResource.adaptTo(ConfigurationBuilder.class).asValueMap();
String param1 = props.get("param1", String.class);
Issue:
ConfigurationBuilder Class is not getting resolved.
Am I missing something? Any help is appreciated..
Regards,
Gopal
Re: Need help in implementing Sling Context Aware Configuration
Embedding the JARs is surely not the right solution. These need to be
deployed as OSGi bundles (as Stefan wrote).

You should check whether contentResource is null before using it: as
per [1] getResource(..) returns null if the resource is not present or
cannot be read.

Re: Need help in implementing Sling Context Aware Configuration
Hi Guys,
thanks for your help, it was indeed a deployment issue.
now we’d need to know how to properly implement a “complex” but rather current
case with country and language subnodes.
Am i right to assume if we want to use default context path strategy we should
add a sling:configRef property to each locale of the content (e.g.
/content/mysite/country/language@sling:configRef), and then manage in the
configuration the fallback mechanism?

RE: Need help in implementing Sling Context Aware Configuration
please have also a look on the documentation [1] [2]
it should work the way you describe having a sling:configRef property on
country node and on each language node.
