There will be no compilation error. The answer will be 2. You will get only the warning "finally clause does not normally completed" not the error.

ram

You should get the return value as 2.You won't get a compilation error. unless you made some typo.the finally will execute in this senario and return you a value of 2.

In case of ServletRequest, we provide the path relative to http request while in the case of ServletContext we provide path relative to root of context.

Spoorthi

Sep 17th, 2006

If we use ServletRequest object then we have to give only the servlet name. For ServletContext object we have to give the relative path i.e, in a context we have more than servlet instances. so we have to give the path from context level.
