You should probably ColumnDecorator since you want to use it in several
places. Here is an example of how to do that.
// in the jsp
<display:column property="dataAvailable" title="Has Data"
decorator="com.microsoft.BooleanColumnDecorator" />
// in the decorator ZeroColumnDecorator
public class ZeroColumnDecorator implements DisplaytagColumnDecorator
{
/**
* retrieve the html decorate string
*/
public String decorate(Object rowObject, PageContext pageContext,
MediaTypeEnum media)
{
String display = "";
if (rowObject instanceof Integer)
{
Integer value= (Integer)rowObject;
// build the html
display=(value.intValue()>0)?value:"";
}
return display;
}
}
