I think EL is not enabled.
Check which kind of JSP you're using. You need to use JSP 2.0 or higher for EL. You can check this in the web.xml
Even i tried the same program and i got the result as .........
Expression Language Variables The script expression for x = 4.
The EL expression for x =.
What is x?
That's true!
its evaluating the ${param.x==4} part,where i am passing the value in the text field and param.num is resolving to that value i entered but its not printing the value of x (at second line) declared .Does EL have any restrictions of such kind?

The EL expression for x = ${x}. is trying to access a scripting variable. EL cannot access scrpting variables.
