Say a text box takes value from Transfer Object as below in a jsp:

<INPUT TYPE="text" NAME="test" ID="test" value="<%=testTO.getTest()%>">

However, if getTest returns null, null will be displayed.

How to use ? : with scriptlet so that if the value is null, blank is displayed else the value returned from TO.
