Getting error while importing muticomposite field

[boomar53364785]

We have used Adobe 5.6 and used Mutlifield composite filed in the component and works without any issues.

After migrating from AEM 5.6 to 6.1 Getting the error in the jsp

An error occurred at line: 27 in the jsp file: /apps/test/components/content/carouselbanner/carouselbanner.jsp

MTMultiCompositeFieldHelper cannot be resolved to a type

<%MTMultiCompositeFieldHelper mht = new MTMultiCompositeFieldHelper();
