Technically, Here you are trying to call java method from javascript.
I did not come across this situation, try full compile if throws any

In detailed compile file, there is call for compile like

My short answer is develop in dev mode as is and deploy in any servlet

If you go to debug configuration, in server tab, you only see

In short there may not be any easy way to debug in other servers.

Hi,
I want to start a new opensource project - "GWT page flows" - similar
to struts.
With my moderate GWT knowledge, I did not find any way to weave
application with pages, though components are there.
Not all ajax applications are single page apps.
Here are my thoughts from very high level -
Eclipse plugin is a real good friend to figure out RPC.
Just create new project choosing both app engine and gwt, creates a
nice working sample RPC , hello world.
Add few more methods for practice, then add few more servlets and call
from client.

Without RPC or its variants, GWT is a pure client technology, as you

Sure. soon.
I am suspecting one of these.
1) Storing in text in app engine
"com.google.appengine.api.datastore.Text" field
2) Using getText() and getValue() - setText, setValue() - using freely
assuming they produce consistent results.
One of these is not working as I expected.

One way is build your own collection (ArrayList) and make accessible,
with setter and getter ,just like in any java class.

Yep. Documentation says use this mode always during development, never

Hi,
We don't have to build the page entirely using GWT widgets,
if playing these in any html is possible, it should be possible even
with GWT.
with HTML5 it is snap to implement this, but GWT does not prevent to
launch player and play anything you want.
Even you can mix Flash with GWT.
You can b
ng, but programming concept
has changed.
May be some reason is there, or I did not understand completely. It is
worth discussing so that we can transition our years of app

Couple of tricks in personal experience.
1) Use concrete classes instead of interfaces, especially in case of

as it does not which class at run time.
