Firstly, they're not errors, they're warnings. So unless you actually
see a problem later on, you may ignore them.

If you don't want to ignore them (and it makes sense that you
shouldn't) then fix them. They are all accompanied by a reasonable
description, aren't they?

What exactly are you having trouble with?

The problem I have is with the persistence, before developing a small application starts using Netbeans, GWT 2.1, 0.5 gwtp all, hibernate, as the tool develops andofficial IDE is eclipse wanted to migrate the code to eclipse, there is now GWT2.4but this persistent problem, no connection to the db, setting, copying sample codenow makes the connection to hang appeared the WARN db and send it.
Now the problem is that data are not displayed any error does not come out and thought it was for the WARN. 19/01/2012 but yesterday I discovered that if you make the connection but no where is the error, plus I can not migrate a portion of code above q is the menu bar on the main screen gives me an error that is:
Error loading menu: 

(as history was developing an architecture for developing application (XXX) that is to create a generic class, etc ...) 

I would appreciate if I can help

This is your first clue (it also appears in the second stack trace).

This is your second clue.

I have no idea what's going wrong but start debugging at the indicated
line and/or figure out where this 'length' property is being used.

Unfortunately, GWT sometimes swallows up entire stack traces making
debugging very hard. In other cases the error message is spot-on and
very descriptive. You may have run into a bug that falls into the
first category.

thanks, I'll keep trying to locate the error be if
