Hi Sahuly,
Custom controls are simply controls created by a developer. For
example, if you need to access several databases using several JDBC
controls, you might choose to create your own custom control which
contains both JDBC controls in order to hide that complexity from the
user of the control.
Typically custom controls are used to access system resources, such as
databases, web services, etc. In the end its really up to the
controls developer.
The control bean and beaninfo classes are generated for a control at
build time. The generated bean class acts as a proxy for the control
implementation -- the bean is the class you are using from a control
client . The beaninfo class is generated to allow for bean
introspection by third party code (for example, an IDE which supports
Beehive controls).
This is a very high overview, but hopefully provides you with some assistance.

hi chad,
First of all i am not clear with the control concepts itself...what
is the exact purpose of customized control...
what is the exact need for that autogenerated bean and beaninfo class...In
the documentation it says like for reducing the J2EE complexity thats
accepted for EJBControl and also for JdbcControl..when we go for the normal
Customized Control...thanks in advance
