Groups are collections of users and/or other groups; these are all called Members of a group.
Their primary purpose is to simplify the maintenance process by reducing the number of entities to be updated, as a change made to a group is applied to all members of the group. Groups often reflect:
a role within the application; such as someone who is allowed to surf the content, or someone who is allowed to contribute content.
your own organization; you may want to extend the roles to differentiate between contributors from different departments when they are restricted to different branches in the content tree.
Therefore groups tend to remain stable, whereas users come and go more frequently.
With planning and a clean structure, the use of groups can reflect your structure, giving you a clear overview and an efficient mechanism for updates.
User Creation Servlet:
Below Servlet creates user under specified paths and add them to specified group when you hit the servlet as
http://localhost:4502/libs/cqusercreation?email=mani@gmail.com&firstName=firstName&lastName=lastName&givenName=givenName&displayName=displayName
with different parameters you can use these servlet in any async call to make a call from the component.
