how to debug or log info in bean

You can log information in the AEM log using code like:

/** Default log. */
protected final Logger log = LoggerFactory.getLogger(this.getClass());
               
private Session session;
private java.util.Iterator<Authorizable> users = null ;
     
//Inject a Sling ResourceResolverFactory
@Reference
private ResourceResolverFactory resolverFactory;
 
@Override
public String getCQUsers() {
         
 try
 {
  //Invoke the adaptTo method to create a Session 
  ResourceResolver resourceResolver = resolverFactory.getAdministrativeResourceResolver(null);
  session = resourceResolver.adaptTo(Session.class);
             
  //Create a UserManager instance from the session object
  UserManager userManager = ((JackrabbitSession) session).getUserManager();
 
   users= userManager.findAuthorizables("jcr:primaryType", "rep:User");
 
  while (users.hasNext()) {
   
      Authorizable auth = users.next();
      if (!auth.isGroup()) {
 
          //Get the ID of the user
        String id = auth.getID();
        log.info("Retrieved USER "+id) ;
            }
        }
     
    // Log out
    session.logout();             
    return "All AEM Users are written to the log file" ;  
}
catch(Exception e)
{
         log.info("CQ ERROR: "+e.getMessage())  ; 
}
         
return null;
 }
}

Hi,

for debugging, did you use the approach defined here: https://helpx.adobe.com/experience-manager/kb/CQ5HowToSetupRemoteDebuggingWithEclipse.html

When creating the debugging configuration, did you define where the source code is located?

I am assuming this is component in OSGI.

I prefer using this library for logging, its very helpful, can you try to integrate this. Its simple

http://www.slf4j.org/manual.html

hi...

yes i am using it. but it is not printing to adobe error.log

and this java class is in <package>.components

what do you mean by component in OSGI?

In OSGI,

Can you open logger configuration and find out whether there is a separate log file configured for your class in  which this code is present.

Also please check what is the log level setup.

Are you able to see logs of other classes ?

Link: http://localhost:4502/system/console/configMgr

Can you please share snippet of your code?

Can you ensure that JAR files required are present in you OSGI.

as far as I can see the core bundle is present in

http://localhost:4502/system/console/bundles

http://localhost:4502/system/console/osgi-installer

I need to show a DAM asset file size in 1 of my components.

So I pass here URL as for example  /content/dam/project_name/<path>/filename.pdf

  private int getFileSize(URL url) {
        HttpURLConnection conn = null;
        try {
            log.info(" URL : " +  url.toString());
            conn = (HttpURLConnection) url.openConnection();
            log.info(" connected");
            conn.setRequestMethod("HEAD");
            conn.getInputStream();
            
            log.info(" input streem");
            
            return conn.getContentLength();
            
           
            
        } catch (IOException e) {
            e.printStackTrace();
            return -1;
        } finally {
            conn.disconnect();
        }
  }

Did you properly declare the logger:

/** Default log. */

protected final Logger log = LoggerFactory.getLogger(this.getClass());

the information is written to the aem log file too. 

Hi,

can you explain how the the URL you are calling will lead to your code being invoked? Are you calling the URL directly?

What kind of Java class is it?

It sounds as if you code is simply not being called. Doing things crudely, you should be able to see "System.out.println("");" statements if your code was being called.
