Derek-
Any conversions (String to Integer or whatever) need to happen in your
Business Bean layer
e.g.
ActionForm which uses Strings and booleans
private String IntegerDisplay = null;
public String getIntegerDisplay()
{
return this.IntegerDisplay();
}
public void setDateIntegerDisplay(String display)
{
this.IntegerDisplay = display;
}
//Business Bean
public class BusinessBean extends BeanUtils
{
//Default constructor as per spec..
public BusinessBean() { ; }
public Integer intn = null;
public String getIntegerDisplay() {
try
{
intn = getInteger();
if(ConvertUtils.isNull(intn)) return null;
return intn.toString();
}
catch(NumberFormatException d)
{
System.out.println("Bad integer has been passed in do something");
}
catch(NullPointerException n)
{
System.out.println("Null found you passed me a null Integer!");
}
}//end getIntegerDisplay
public void setIntegerDisplay(String display)
{
if(display=null) intn = null;
else
{
try
{ //set the value..
setDisplay(Integer.valueOf(display));
}
catch(Throwable t)
{ //exception found set to null
setDisplay(null);
}//end catch
} //end else
}//end setIntegerDisplay
Now what is that about teaching a man to fish?
Hope this helps,
