This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
You cannot pass parameters. And if your class has methods such as that, it's not a "bean" by definition.
The real answer is to rethink how data is being passed to the page, and to change the data classes made available to the JSP to actually be beans. But that may be a refactor that you are not prepared to do.
It's very difficult to convert a JSP from scriptlets to JSTL/EL using a line-by-line approach because with scriptlets so many bad practices are possible on the page (which is why scriptlets are discredited), so a line-by-line replacement is usually not possible.
If you just want to replace that one line without refactoring, you'll either need to create a custom tag or an EL function.
