Finder methods

[ALaxmi Shankaran]

Can the finder methods be called from the servlet.

Which is the better option 1) calling them directly from servlet
2) write a wrapper method in session beanto call them ?

Why?

[Amit Jaipaul]

Hi,

There is no harm in calling finder method from a servlet. We can very well call them from servlet.

It is better to call Entity Bean finder methods from Session Bean and put the corresponding values of the business object into a value object and pass it to the client.

ENTITY BEANS SHOULD NEVER BE EXPOSED TO CLIENT. ALWAYS USE IT THRU A SESSION BEAN.

[Valentin Crettaz]

Note that Unni is talking about the Session Fa�ade J2EE pattern:

Use a session bean as a facade to encapsulate the complexity of interactions between the business objects participating in a workflow. The Session Facade manages the business objects, and provides a uniform coarse-grained service access layer to clients.
