Hi,

Was just ooking at RAP and had few questions in mind, will be great if
some one can shed some light on these:

1 How search engine friendly is RAP application?

Is it possible to index all pages of RAP?

Are their some guidelines / best practices for RAP developer?

2. Can somebody suggest good RAP hosting service i.e. Tomcat hosting
service?

Looked on net and found few, but java/Tomcat based hosting is expensive
(as compare to PHP) and dedicated RAM allocation is around 256MB.
Further, one has to pay more if needed more. So just wondering what
services people are using, any recommendations/suggestions?

3. Further, for dynamic i.e. database oriented RAP application; is
tomcat alone sufficient along with hibernate? i.e. as I see that JBoss
is not required if ejbs are not used and tomcat can handle
multiple/concurrent users/session, am I right in saying so.

4. Is there some tutorial / best practices i.e. how to develop RAP along
with database?

5. Which application is more scalable, one developed with GWT or with
RAP i.e. which application can support more concurrent users with same
amount of heap allocated in Tomcat say 256MB. Any thoughts?

6. Is back browser button supported in RAP based application?

7. Any book in pipeline? :-)

Thanks for your time.

Apart from configuring the meta tags of the index.html page, there
is no support for search engines in RAP.

Sorry, but I can't help you with that.

Yes.

Not that I am aware of. In general, you can refer to best practices
and tutorials for database application development in servlet
environments.

This very much depends on the specific application you have in mind.
Ther following are two pointers on this topic.
http://www.eclipsecon.org/2008/?page=sub/&id=215
http://rapblog.innoopract.com/2008/10/performance-testing-ra p-on-cloud.html

If you search the web you will probably find many more.

Could you clarify what exactly you mean with this?

Yes.

I meant, "Back" button on browser, normally it takes back user to
previous action/html page, but in ajax (I think) normally browser is not
aware of history so generally that functionaly doesn't work.

As a RAP application runs within one single HTML page, using the Back
button means to leave the application. The framework warns the user by
displaying a dialog if he really wants to leave the page.

This is not on our current roadmap.
