Multiple javascript exception handling in GWT

Question

I wonder how people usually do to handle multiple exception from javascript in GWT? for example, this method from the IndexedDB specification :

IDBRequest add( in any value, in optional any key ) raises (IDBDatabaseException, DOMException);

It can raise two JavaScript exception objects, so i have no idea how to implement wrapper for it in Java.

Answer 1

There exist an

GWT.setUncaughtExceptionHandler(new ClientExceptionHandler());

Its already discribed here: GWT.setUncaughtExceptionHandler()

I don't think I have to add anything:)

Answer 2

I used the java's try catch to catch javascriptexception. it works well:)
