TLD example in HFSJ

[Sreedhar]

In HFSJ, there is a example for writing functions in TLD.
Example on page 389.

--------------------------------------
Code in TLD:


<description>JSTL 1.1 functions library</description>
<display-name>JSTL functions</display-name>
<tlib-version>1.1</tlib-version>
<short-name>mine</short-name>
<uri>DiceFunctions</uri>

<function>
<description>
User defined TLD.
</description>
<name>rollIt</name>
<function-class>com.scwcd.apps.util.DiceRoller</function-class>
<function-signature>int rollIt()</function-signature>
</function>

Code on JSP:

<%@ taglib prefix="mine" uri="DiceFunctions"%>
${mine.rollIt()}
I get error :

The function rollIt must be used with a prefix when a default namespace is not specified

But if i change the code to --> ${mine.rollIt} // here the brackets are removed. I do not get any error but i also do not get any output.

----------------------------------------------------

Thanks in advance.

${mine:rollIt()} should be correct.
Try it so.

${mine.rollIt} works but you don't have any output because "mine" attribute is searched for in any scope but it doesn't exist and null value in output bacomes an empty string

Bye.
