When dealing with use input I usually use the following... which will
evaluate to true only if strValue has more than one non-space
character. i.e. a string with only spaces will be treated as no input.
if (strValue != null && StringUtil.trim(strValue).length > 0)
{
//your code here
}
if you want to process input that has only spaces just leave off the
call to StringUtil.trim.
