Hi,

Deploy the Application once again, it will solve this problem. If it is coming once again, delete the component from Visual Composer and re-deploy it.

Hopefully it solves your problem.

Hi Sridhar,

Can you please tell me how to delete the component from Visual Composer ?

Hi Venkatesan,

It is Visual Administrator. I mistakenly written it as Visual Composer.

To delete a component

Open the Visual Admin

usr/<j2ee instance>/JC01/j2ee/admin/go.bat

In the visual Admin -> Cluster -> Server -> Services -> Deploy.

It will list all the deployed Services. From web dynpro -> Select your project -> Remove that project.

Regards,
