In JSP, is there a way to see all available variables in the specific scope like in PHP?

Or better yet how do I dump all the variables in a given scope in jsp?

(In php you can use a function call to see all the system, globa开发者_运维问答l and user-defined vars and functions available...)

Yes. See this article for an overview of all objects that can be accessed, and a small piece of demo code demonstrating the access per object using the JSTL.
