equivalent of checked attribute of radio button in struts

[Pranav Pal]

What is the equivalent attribute of "checked" attribute of <input type="radio"> in <html:radio>?

[Merrill Higginson]

There is no such equivalent. A Struts <html:radio> tag is tied to the ActionForm bean property specified in the tag. If the ActionForm property is set to the value specified in the tag, the button will show as checked. Otherwise, it will show as unchecked. Example:

<html:radio property="color" value="red">Red
<html:radio property="color" value="blue">Blue
<html:radio property="color" value="green">Green

In the above example, if the form bean property "color" contains "blue, the second button will be checked.
