how to read OSGI configuration via JAVA

[INeedYourHelp12]

so I have the code below

I have a breakpoint in this line 27 and another one in line 29.

when debugging my code (eclipse user here), the program stops at the first breakpoint. And when I resume (F8), it never stops in the second breakpoint. I suppose something happened to it (fatal error perhaps) and my page loads completely as if nothing happened.

This is how I call the JAVA code:

<sly data-sly-use.protectedflag="${'com.mycompany.core.impl.view.tools.checker' @ path=currentPage.path}"/>

Any ideas what I could be doing wrong? Thanks

package com.mycompany.core.impl.view.tools;
import com.adobe.cq.sightly.WCMUsePojo;  
import java.io.IOException;
import java.util.Dictionary;
import java.util.Hashtable;
import java.util.Map;
import org.apache.commons.lang.StringUtils;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Reference;
import org.apache.felix.scr.annotations.Service;
import org.apache.sling.commons.osgi.PropertiesUtil;
import org.osgi.service.cm.Configuration;
import org.osgi.service.cm.ConfigurationAdmin;
public class checker extends WCMUsePojo {  
    private boolean protectedPage;
    @Reference
    private ConfigurationAdmin configAdmin;
    @Override  
    public void activate() {  
        try {
            Configuration conf = configAdmin.getConfiguration("org.apache.sling.engine.impl.auth.SlingAuthenticator");
            String path =  get("path", String.class); 
            @SuppressWarnings("unchecked")
            Dictionary<String, Object> props = conf.getProperties();
            protectedPage = false;
        } catch (IOException e) {
            protectedPage = false;
        }
    }
    public boolean getProtectedPage() {  
        return protectedPage;  
    }  
}

You should use @Inject annotation instead of @Reference to initialize service while extending WCMUsePojo

@Inject

private ConfigurationAdmin configurationAdmin;

[Feike_Visser1 · Accepted solution]

Both @Reference or @Inject won't work with WCMUsePojo.

To get a Service-reference, you need to use getSlingScriptHelper()

[VeenaVikraman]

As Feike suggested you might have to get the service using the below code snippet

[smacdonald2008]

To see what Feike suggested in a full example - see this article where we get a reference to another AEM Servicve from a Class that uses WCMUsePojo -- Scott's Digital Community: Creating an AEM HTL component that queries the JCR

Question:

Will the activate() gets called when we update the config?

I believe activate() is only called once when the service gets activated or does it have a different way of working with WCMusePojo?

[Jörg_Hoh]

Hi,

WcmUsePojos are no services, but -- as already indicated by the name -- simple pojos. Therefor all mechanics which are available for OSGI components are not available. activate() is never called during the rendering by the framework.
