If you're iterating over a list of beans and the checkbox represents a boolean value in one of those beans, you should use <html:checkbox> and specify an indexed property as the property. This link will show you how to use indexed properties.


<logic:iterate id="user" name="users" >
<html:checkbox name="user" property="registered" indexed="true" value="true" />

If you have a situation where the user is selecting one or more values from a list of possible values, you should use the <html:multibox> tag instead of <html:checkbox>. Use the same property nane for each tag, and make sure the value="" is different for each iteration of the tag. In your ActionForm make sure the property used by the checkboxes is of type String[]. When the form is submitted, your ActionForm will contain an array containing one element for each checked box that contains the value specified for that box.


<hml:multibox property="color" value="blue" />
<hml:multibox property="color" value="green" />
<hml:multibox property="color" value="yellow" />
<hml:multibox property="color" value="red" />
