 Q303. Is it necessary to specify "employeeId" with @PathParam("employeeId") in this case,

@Path("/{employeeId}")
public String employeeInfo(@PathParam("employeeId") Long employeeId){
}		Rest
Ans. No, it's optional as the name of path param required is same as method param name in this case.

 Q304. If given a choice , which one would you prefer to send params to the Get service , path params or query param ?Web Service
Ans. If the number of params is quite large , I would prefer to either split it with majority of it in query params or all in query params.

If the params are all mandatory , I would keep it as path params. If it's optional , I would keep it as query param so as to keep consistent base url.

If we don't require the param name , then they can be kept as path params as query params necessitates the usage of param name.

 Q307. How would you go about creating a get rest service if it requires multitude of params or inputs ?Rest
Ans. If the number of input values is large, we can go about passing them as query params instead of path params. If the number is even larger and complex , its better to create a post service that behaves like a get service. Though this practice is not recommended but technically it can be accomplished.I dont mind doing it if the exceptionally large number of input would make it much more confusing.

 Q310. What is stub and skelton ?SOAP
Ans. RMI uses a standard mechanism for communicating with remote objects i.e stubs and skeletons. A stub for a remote object acts as a client's local representative. The caller invokes a method on the local stub which is responsible for carrying out the method call on the remote object.

Stub resides at the client that upon calling whose method results in establishing connection with the server, serializing and mar shelling the request and then waiting for the response whereas skelton resides at the server that receives the request, unmarshal it and then deserialize to fulfil the request.
