Using GWT with PHP through HTTPRequestObject
Shanky
PHP script residing behind APACHE webserver.
I am using HTTPRequest.asyncPost() method with a URL like
http://someipaddress/process.php.
OnClick of a button, the program just tries to send a HTTPasync request
by posting the above URL..
Surprisingly, the post doen't go through at all. I mean, when I debug
this program using ECLIPSE, I could see that the
HTTPRequest.asyncPost() is doing nothing and it jjust comes out...
I tried to observe the packets sent using ethereal and there are no
packets sent out....
Please give some clues as to what the problem could be??Does this
HTTpRequest works at all??
One more interesting thing is that the generated JAVASCRIPT file
(generated by compiling the above JAVA code), does not contain even a
mention of the URL (http://someipaddress/process.php)??
I mean the javascript file should have this right in order to send the
request on click of the button??
Please help...

domain...
Still this problem is there...

relative folder in your server. There, you can provide a full URL
(including the IP) or you can leave it relative. When running in hosted
mode, you have to use full URLs. I use this code to generate my URLs
and I have no problem posting to php:
private static final String BASE_HOST = "http://localhost/project";
private static final String BASE_HOST_SCRIPT = "/project";
public static String url(String relative)
{
if (GWT.isScript())
return BASE_HOST_SCRIPT + relative;
else
return BASE_HOST + relative;
}
and I use it:
HttpRequest.asynPost(Server.url("my_file.php"), "some post data here",
myhandler)
Hope that helps

I was accessing a URL in a different domain..that's why
XMLHTTPRequest.open() was throwing "permission denied" exception as u
mentioned...
Thanks once again..
