That's because for the print job you are not going through a proxy. ExtJS
doesn't "know" about your OL ProxyHost unless you are using the
ext-override-ajax.js file which is not included by default.
Options 200
text/plain(NS_ERROR_DOM_BAD_URI)
http://demo.opengeo.org/geoserver/pdf/create.json
As you can see from HttpFox, your request is going directly to demo.opengeo.org
but your webpage is hosted at localhost:8080
The 2 solutions are:
1. Use ext-override-ajax.js -> it will send all request through OL rather than
ExtJs and will be aware of and use the OL ProxyHost
2. Intercept the actual ExtJs request and modify the url before it is sent.
Here's an example of how I did that:
....
Ext.Ajax.on('beforerequest',App.interceptPrint,null,{single:true});
App.printProvider.print(mappanel,printPage);
....
App.interceptPrint = function(conn,options){
Ext.apply(options,{
url:Ext.urlAppend(OpenLayers.ProxyHost, Ext.urlEncode(options.url))
});
Ext.Ajax.request(options);
return false;
}
/* I also apply my own callback & success functions to handle the print request
response
myself and prevent the PrintProvider from handling it. I include them after the
'url' property.
However, that is not something you probably want to do, just letting you know
that you can

Subject: Re: [Users] Printprovider problem
I have included my OpenLayers.ProxyHost statement at the top of my script.
Last week when I was scratching my head I confirmed my proxy was working by
doing some wfs requests opengeo and my production geoserver. They worked.
I do not know why I am fighting a proxy issue with the printProvider but in
other circumstances I know my proxy is working.

That is because you need a proxy to get around the Same-site Origin Policy

Subject: [Users] Printprovider problem
I have recently installed the geoserver printing module and set up a app using
the PrintProvider. The development went well until I realized that GET was not
going to work for me because of the URL length. After changing the method to
POST I cannot get the printing to work at all in firefox. I have taken a step
back and am currently testing with a local copy of the geoext example
print-page.html and getting my printCapabilities from demo.opengeo.org or
localhost:8080
I believe have a proxy problem but I do not know why, nor how to fix it .
In config.yaml I have the entries
- !localMatch
dummy: true
- !dnsMatch
host: demo.opengeo.org I have tested with and without the line port:80
I can load the printCapabilities from opengeo and localhost
After clicking the print button in HttpFox I see (going to opengeo)
Method Result Type
url
Options 200
text/plain(NS_ERROR_DOM_BAD_URI)
http://demo.opengeo.org/geoserver/pdf/create.json
I have a similar error from my localhost
The BAD_URI error indicates different domain names are being used, but I do not
see that as being the case., and Method Options tells me I have a proxy issue.
My local test environment is geoext 1.0, geoserver 2.0.3 (jetty), OpenLayers
2.10, extjs 3.3.1, windows XP, and my web server is IIS
When going to my localhost after clicking the print button
The printprovider print exception listener response.statusText is
"communication failure"
My geoserver request log has "OPTIONS /geoserver/pdf/create.json HTTP/1.1" 200 0
My geoserver.log contains DEBUG [geoserver.filters] - filtering
http://localhost:8080/geoserver/pdf/create.json
I'm lost. Any suggestions on what I am missing would be appreciated.
The post will work in IE 7 & 8. I do get the message "This page is accessing
information that is not under your control. . Do you want to continue"
