Hi Varun,

Packages which are needed by the bundle are listed in 'Import-Package' 

Some of the packages from the bundle would be used in the other bundles. Such packages are listed in 'Export-Package' to make it available for the other bundles.

• Import-Package: Indicates which Java packages will be required from the outside world to fulfill the dependencies needed in a bundle.
