Exception handling in flow script
Hello all,
Is it possible to catch and handle a specific exception class in flow script, like it
is in Java? For example:
try {
registrator.register()
} catch (RegistrationException e) {
// do something
}

Someone can correct me if I'm wrong. But I dont think you can use the
Java syntax for catching typed Exceptions in Javascript. I think you
have to test the exception type in the catch with an if-statement
instead.

Martin,
again yes. Specify the class you wish to catch as you have done:
>>> } catch (RegistrationException e) {
>>> // do something
>>> }

I think you can do something like this (although I've never tried it):
try {
artist = Artist.getArtist(cocoon.request.artID);
} catch(e) {
if (e instanceof TypeError) {
// do something
} else {
// do something for all other exceptions
}
}
Hope this helps.

IMHO, if you need to catch the exact type of exception and try to do
something you should do it in business methods other than in js. In
js, the exception is used to send some pages to notify client
something was wrong and the exact type can be filtered by exception
handler in sitemap.

But in this example all exceptions are caught. Instead I want to catch and handle
only exception of specific class and I want all other exceptions to be handled
by the default handler.

Martin,
in a word, YES!
importClass(Packages.test.Artist);
var artist;
var error_msg;
function artistDetails() {
try {
artist = Artist.getArtist(cocoon.request.artID);
}catch(e) {
error_msg = e.toString();
}
hope that helps ;-)
