How to write HTML from java page

[newbie newbie]

Hi,

I need to write HTML from my .java page. Here is what I have tried

This is my tml code fragment

${testFunction()}



This is my java code fragment

public String testFunction()

{

     return "<input type='checkbox' name='leaf' id='leaf' value='leaf'/>"

}



The result I want is a checkbox. What I get is a string "input
type='checkbox' name='leaf' id='leaf' value='leaf'".
Any help would be appreciated Thanks.
