[Geoserver-users] invoking geoserver servlets from another web app

GeoServer GeoServer User
1

Hi,

I am new to geoserver and have basic servlet
knowledge my question is:

Can I build a web application e.g a couple of servlets
archived in war file
that gather map (wfs) request from a user, then invoke
the required
geoserver servlet to provide a response ? Put in
another way, is it possible for my servlet which is
archived in a separate war file to invoke a geoserver
servlet to provide a response
since geoserver is archived in a separate war file ?
How can I do this.

Thanks in advance

Roman

Sure you can, invoking WFS from java code is dealt with in the FAQ:
http://docs.codehaus.org/display/GEOSDOC/How+do+I+make+a+WFS+request+in+my+JSP-Java+code
http://docs.codehaus.org/display/GEOSDOC/My+WFS+request+in+Java+does+not+work.

All you have to do is to read the response and return it back to your
client. Also the code in https://svn.codehaus.org/geoserver/trunk/geoserver/wfs/src/main/java/org/vfny/geoserver/wfs/servlets/TestWfsPost.java
can be of inspiration, since this servlet exactly takes a form with
some request as a parameter, calls WFS/WMS/WCS and the returns the
response to the client.

Cheers

Hi Roman,

Do you need direct access to the servlets running inside of geoserver... or can you just go through the wfs protocol. Ie. make a wfs request just like a normal client would.

Hi justin,
Yes, I think I need direct access. I was told that I
can use a request dispatcher. Can I have sample code
on how to do this. how can I pass the shapefile and
the OGC filter using the request dispatcher. Thanks

Hi Roman,

Well I think the links that Andrea sent out are the only way to do this... You cant really get access to the servlets running in geoserver... everything is through http. The closest thing might be an RPC or remoting interface... but GeoServer is not currently set up like that today.
