okay let's say i have something like

try {
myBooks.insert(new

Resource("c","ISBN","LCN","publisher","aerg","aergaerg",4,"2006-10-12",156))
;

myBooks.insert(new

Resource("d","ISBN2","LCN2","publisher2","dbdb","earg",4,"2006-10-11",179));

myBooks.insert(5);
myBooks.insert(new

Resource("a","ISBN2","LCN2","publisher2","g4gaer","vearv",4,"2006-10-11",179
));

myBooks.insert(new

Resource("f","ISBN2","LCN2","publisher2","aergaerg34","aervrev",4,"2006-10-1
1",179));

myBooks.insert(new

Resource("q","ISBN2","LCN2","publisher2","far3w2","rfvaer",4,"2006-10-11",17
9));

}
catch( ListException le )
{
System.out.println(le);
}

but insert(5) throws an exception. so it prints a nice little error
message.. but then the rest of the inserts are skipped!

how could i get it to print the error, and then continue the rest of
the inserts, throwing exceptions as necessary...without putting a try
catch around each statement? is it possible?

put your Resource objects in an array or a list and iterate over it, doing
the insert in the try/catch

Yeah.

Basically, and in psuedo-code:

String myData [] = "c",
    "ISBN",
    "LCN",
    "publisher",
    "aerg","aergaerg",4,"2006-10-12",156
    // etc... all the data here

foreach( C in myData )
{
    try (
        insert (C); // somewhere...
    } catch Error (e) {
        println ( e ); // barf up a hair ball
    }
}

i guess that's a good way of doing it :) thank you
