Overloading an EL function defined in TLD

[Anand Wadhwani]

Is it possible to overload an EL function? Please look at following piece of TLD:

<function>
<name>rollIt</name>
<function-class>com.Person</function-class>
<function-signature>int rollDice()</function-signature>
</function>
 
<function>
<name>rollIt</name>
<function-class>com.Person</function-class>
<function-signature>int rollDice(int)</function-signature>
</function>

And following piece of JSP to call above two overloaded functions:

Dice Rolled, outcome = ${diceroller:rollIt()}
Dice Rolled, Multiplied outcome = ${diceroller:rollIt(2)}

When I try to run the JSP, I get following error:

Duplicate function name rollIt in tag library /WEB-INF/eltest.tld

Could anyone please confirm that EL functions cannot be overloaded!
Thanks!

I guess, the answer is Yes. But as suggested by Kumar, the names that map to the function definitions have to be unique.

JSP2.0 Specs, JSP2.6.2, page:1-77,

A tag library can have only one function element in the same tag library with the same value for their name element. If two functions have the same name, a translation-time error shall be generated.
