GWT front-end with PHP backend

[rajath]

Hi all,
I recently tried my hand with GWT hosted on GAE/J, and found it to be
really good, especially considering that i did not have to learn
javascript. I want to try to build the front end with GWT, but for the
back end, we already have a php server which gives json data over
restful urls.

I have read in other places that the communication between GWT and php
can happen with a few tweaks. My questions are related to the
following, which is confusing me - does the gwt-created js files have
to be served from a Java-server (or GAE)? Is there some way for the
php server that we have to serve these js files?

Any help would be much appreciated. Thanks, Rajath

gwt created js is nothing but a normal JS ,executed in browser.

so backend is either PHP or Java.

if you use ajax in GWT and server side is PHP then you use RequestBuilder Class.

if server side is Java then you may use either RequestBuilder/GWT.create(abc.class);

Hi Rajath,

I've been using GWT with PHP backends, almost exclusively, with great
success. The GWT docs have a pretty good tutorial.
http://code.google.com/webtoolkit/doc/latest/tutorial/JSON.html#client

Just ignore Section 1 ("Creating a source of JSON data"), which talks
about implementing the server-side in Java. It sounds like you have
the server-side portion of the work already done.

The GWT-created js files do not have to be served from a Java server;
they are just served as static files like any other
standard .html, .jpg, .gif, .js, etc. files. You can serve them from
the same server running PHP. If you serve the js files from a server
on a domain other than the server providing the JSON, you will need to
watch out for the same origin policy (http://en.wikipedia.org/wiki/
Same_origin_policy).

For cross site requests. It also uses PHP script in the example.
