[Gwt-openlayers-users] WMSGetFeatureInfo not working

[Dave P. <dav...@pi...>]

Hi List

Was a solution ever found for this problem, because I seem to be getting
the same issue.

I attempt to make a request to geoserver instance running on the same
tomcat webserver with a valid layer name via a wmsgetfeature request,  I
get callback with an empty result.

I lhave ooked at the geoserver logs and can see geoserver getting the
request from the gwt-openlayers program and see the request to  my postgis
database.

Feeding the same sql request into the database, generates data.

Using firebug and copying the text of the feature requests, results in to
firefox returns a result.

Using firebug of the gwt-program, shows the reques set to geoserver.  A
callback is received but the results section is empty.

I do not think it is a proxy issue because both my instance of geoserver
and my gwt-program are bothing running on the same server.

I have tried the example from showcase which works correctly. AS far as I
can make out the showcase example and my owner server are setting the same
param strings so I should receive a result.

It is possible to use the 'internal version of openlayers' in the layer
preview  option to look at the data and everything seem to be correct.

I just wondering what is going wrong!  If geoserver was not processing the
request I should not receive a callback, but I do. If the feature request
was invalid I would not see geoserver accessing my database, but it does.
(There is no logging to say what geoserver actuall generated, even at the
finest setting)

If there was something wrong with the request,  I would not see a correct
result from geoserver when I make the same request directly via firefox,
but I do.

Does anybody known any method of seeing what geoserver generates for an
gwt-openlayers program ?

I do not suspect a bug,  I suspect a projection issue i.e. my program has
said something like give  give me all the information about features near
point x/y. Geoserver has generated a null request because it could not
find anything because its concept of X/Y is different to my program
concept of X/Y.(Firebug and Geosever both claim to be using the same srs
value)

Dave.

Might it bee that you need to proxy your result as the application resides
on port 8080 and the geoserver on 9090. That would explain why it works in
the browser but not in the application. I think that you should get an
error in that case though, something like "forbidden location" or the
like.

I tried to have a look with firebug, and when I click on the map there is a
GET request as follows:

GET

If I copy the address of the request in my browser I can see the HTML
response right as it should appear, but in firebug I find the Answer and
HTML tabs completly empty! What else can I check?

Thank you for the help...
