I've created a code just like on page 393 of Head first, but while accessing a page from JSP by using an expression: ${mine:rollIt()}, it's displaying as it is as a string literal in the output in JSP, instead of calling the real function which is stored in the function-signature tag in TLD file. Why is that so?

Here's the TLD file which is just like on Head first book page no. 393:


and here's the JSP code:

Try to put missing tag in the TLD
<short-name> somename </short-name>
just after <tlib-version>

It may help.

I've not declared any el-ignored tag in DD.

The request is going straight to JSP. Although, I checked with request going first to servlet then to JSP, but still getting that string literal as an output.
