In case of checkboxes (and radiobuttons) you'd like to set the checked attribute.

<input type="checkbox" name="group" value="${grp.groupNo}" ${grp.groupNo == param.group ? 'checked' : ''}>

The conditional operator ?: in EL will print checked when the condition is true. So it will then end up like follows in generated HTML:

<input type="checkbox" name="group" value="1" checked>
