Well, hello Bill,
First Q.
I like to run all my bean property getters through an encoding function,
which you can also use to capture the "null" value. Assuming you are doing
all your data manipulation in beans and then returning the values to JSP
through getXyz() methods called from <jsp:getProperty> tags, I do something
like:
public class ABean {
private String aProperty = null;
public String getAProperty( ) {
return(JSPUtil.toHtml(this.aProperty));
}
}
My JSPUtil class contains a lot of static methods to do various simple
JSP-related functions, including "encoding" String values so they are HTML
friendly. For example:
static String toHtml (String value) {
if (value == null)
return "";
else
return JSPUtil.encodeHtml(value); // I must write this one day...
}
I then create overloaded versions of the toHtml method for floats, ints,
booleans, other specific classes etc as needed. They are produce a String
value, which they run through the toHtml(String) method. This way you can
capture the "null"s and also handle HTML character entities etc in one
place. I do a similar thing for encoding the values that will end up as
HTML tag attribute values - eg. double quotes kill them.
Second
Yes, there are archives, they can be found at http://archives.javasoft.com.
I though they were listed at the bottom of each message to this list, but it
doesn't seem to be there now.

Drew Cox
