Can you follow this  article and see if that works:

This will tell us if your issue is your environment. If this works - we can rule out an environment issue.

Share the code for your WCM class in java

By the exception message it looks like the template engine is not able to access the mentioned class file. Could you please check once that you class is present in the OSGI and the bundle is also active. Not exactly sure though.

Regards

Please consider com.prj.dcom.sightly.helpers.components.HomePageBannerComponent this only.

And also i am seeing below error as well.

11.03.2016 00:53:30.565 *ERROR* [127.0.0.1 [1457637810506] GET /content/www/in/en.html HTTP/1.1] com.adobe.cq.sightly.WCMUse Failed to activate Use class

 

Thanks,

Just wondering.....y these two class names are different

One in exception

io.sightly.java.compiler.CompilerException: java.lang.ClassNotFoundException: com.xxxx.dcom.sightly.helpers.components.HomePageBannerComponent

and one in sightly file

<section data-sly-use.homePageBannerComponent="${'com.prj.dcom.sightly.helpers.components.HomePageBannerComponent'}"></section>

Second thing....................

use this 

<section data-sly-use.homePageBannerComponent="com.prj.dcom.sightly.helpers.components.HomePageBannerComponent">

instead of

<section data-sly-use.homePageBannerComponent="${'com.prj.dcom.sightly.helpers.components.HomePageBannerComponent'}">

Hi Scott,

Thanks for the reply.

Helper class is implementing WCMUse interface and also bundle is activate state as well.

Syntax for getting this class inside sight component is as below.

<section data-sly-use.homePageBannerComponent="${'com.prj.dcom.sightly.helpers.components.HomePageBannerComponent'}"></section> 

Thanks,

Kishore
