WCMUsePojo in AEM6.3 not working

[prashanth55]

Hi All,

I have created a class which extends WCMUsePojo. But it's not working, it is giving following error.

com.adobe.cq.sightly.WCMUsePojo Failed to activate Use class

java.lang.NullPointerException: null

This is the code:

import com.adobe.cq.sightly.WCMUsePojo;

public class TestUse extends WCMUsePojo {

     String text;

    @Override

    public void activate() throws Exception {

    text = get("text", String.class);

        log.debug("Text: {}", text);

        log.info("--- Started : : Activate");       

    }

    public String getText (){

        return this.text;

    }   

}

I have also included uber.jar in the pom.and the bundle is in the active state.

Please help me to resolve this issue.

I think it is because of log.debug. I don't see creating an instance for the Logger class in your code.

code will not compile if that's the case

You should be seeing line no where NPE is occuring, can you check?

Also is that the complete code?

Make sure you bundle is resolved in felix

Hi,

Please check Adobe Experience Manager Help | Creating an Adobe Experience Manager HTML Template Language componen...  to see how to use WCMUsePojo

How are you deploying bundle ? are you deploying through Felix console ? or did use CRXDE to create a class? please post entire code?

Try below code : to read value from dialog we should use below code

getProperties().get("text", String.class);

I think get is used when you pass a parameter from sightly. this caused null pointer exception

get("text", String.class);

Can you share the full stacktrace? And also the code seems not to be complete.

Thanks All, the issue is solved. The acs-commons bundle is causing the issue because of twitter dependency. It is working fine after adding twitter bundle and restarting the core bundle.

Good to hear, although I can't see how this bundle can affect this.
