Hi @vinuu123 ,

Do you want to add more details on what you want to achieve in that servlet?

Thanks,

*WARN* -  GET /content/project/us/en/about-us/events/shows/ampp-1010.thumb.600.600.png HTTP/1.1] com.day.cq.wcm.core.impl.servlets.ThumbnailServlet Cannot create thumbnail 2java.lang.NullPointerException: null

this is the error/warning I am getting

I want to create custom servlet to avoid this warn, by adding default thumbnail

You should debug, from where this image request is generated and fix the code, instead of writing custom servlet to handle this error.

How can I debug that ?

[Mohit_KBansal · Accepted solution]

Check the component which is rendering/calling this image. Also, check JS if needed. It's your code, so you should be able to better drill it down.

Thankyou so much @Mohit_KBansal

@Mohit_KBansal I want scenario like, if thumbnail is authored it is showing that original thumbnail in the page, if not authored I want default thumbnail.

If you are using custom model, set you imgSrc field value like

If imgSrc configured in the component
    set imgsrc=component's imgSrc
Else
    set imgsrc=DEFAULT_IMG_PATH

In your HTL, just use imgSrc

<img src="myObj.imgSrc">
