Difference between attributes and parameters.

[Rachit Kumar Saxena]

While theres a getInitParameter method,theres no setInitParameter method in ServletContext CLASS.But you can also set and get an attribute.Why?What is the difference between parameters and attributes?

[Ashish Hiriadka]

ServletContext Init parameter are for passing any values which doesn't change very often. So there is no setInitParameter() method in servlet context.

Thanks for the reply!!! But I would like to know IF setInitParameter had been used,it would have given the user the option of changing init parameters in java apart from the xml file.Your views?

Speculation is useless -- init parameters are intended to apply constant values for the servlet instance.

init parameters are loaded along with servlet, that is at it's one time instanciation time, while attribute are the object which are passed , set, and get at run time when we need them......
