I've tried using logic:notEqual property="myBean.item1" value="null" and logic:present name="myBean.item1 but to no avail. The first thing you tried would compare to the literal string "null", which is not what you want. The second test is invalid because the nested property syntax works only on the "property" attribute, not "name". If "item1" is the name of your bean property that might return a null value, try this: logic:present name="myBean" property="item1"/ ... the value is not null ... /logic:present or logic:notPresent name="myBean" property="item1"/ ... the value is null ... /logic:notPresent Can anyone help me out here.
