Wow, that is a long thread!
I read / skimmed through the full conversation and what I take from it is
there are numerous ways this could be done that would increase complexity,
deviate from GeoServer's UI philosophy, and consume lots of developer time,
but that Andrea's original suggestion - to
I've created a function within Oracle for on-the-fly clustering that I hoped
to query via GeoServer using an SQL view layer.
The function takes as its arguments the bounding box and the number of grid
cells to use in a basic gridded clustering process (i.e. find the centre of
mass for points
I think I've discovered a bug in 2.6.1 but I need a second opinion. I
upgraded to 2.6.1 from 2.2.5 so as far as I know the issue could have been
introduced anywhere in between.
I have a line layer in Oracle Locator 11gR2 with around 100,000 features
(all 2-vertex lines, no line strings).
Playing around with the 'Edit gridset' page under 'Tile Caching' in the
GeoServer admin area I see that GWC / GeoServer is able to retrieve the
maximum extent of the CRS set in this page.
I'm interested in learning how this query is performed, and if I can use the
same functionality in my own
Yes I would expect your new command to work fine but there are a few possible
explanations for why it might fail.
1) the target of your new path is different to your original relative path -
I assume /var/www/geo/shapefile/csvQshp/ does actually contain shapefiles
2) you might be seeing
Did you try using an absolute path? GeoServer needs to be able to find the
group of files that make up the Shp, but your path is relative to your pwd
in the shell.

OK, I'm still a bit lost, I have a feeling it's simpler to use my application
as a proxy and deny all access to GeoServer that doesn't originate from
localhost. Appreciate the suggestion

I have a page in an existing Spring-based Java application that uses
GeoServer (2.2) via WMS WFS, with requests originating from the client.
Users have to authenticate with the Java application but currently GeoServer
OWS services are accessed anonymously.
This is changing, and now OWS services
Hopefully this is quick and easy question for someone with the knowledge.
GeoServer lets me use well-known shapes for point symbols, e.g. circle
square triangle etc. When rendering large numbers of features I have seen
that these symbols are rendered much faster than external graphics.

I know this is an old thread, but I just wanted to add some recent wisdom. If
you set the correct min / max ratio on the overview map you can still use
the cached service for it.
The overview control has minRatio and maxRatio to specify the ratio of the
main map area to the overview map area. If
Christian, Andrea: I really appreciate you providing test results and putting
in the effort to help me figure out what's going on. My next step is to test
with a Shapefile data source, hopefully I will see much better results.
Andrea: you said

I agree that there is value in limiting what is rendered, but my current
concern is whether what I'm seeing performance-wise indicates a problem in
my GeoServer setup or is just normal behaviour. If there is an issue, and
130,000 should render quicker, then I might still see sub-optimal rendering

Yukka: unfortunately yes, at this point it is necessary to draw all the
points. I have to show their distribution so I can't hide some and show
others as it would misrepresent the overall shape. As their locations
frequently change it is not feasible to calculate any of this in advance and
Andrea: thanks for your input.

Is the point symbolizer the only thing you have in the style?
No text symbolizers for example?
What version of GeoServer are you using?
I am only using the default point symbolizer with no graphics, labels,
filter rules, scale dependencies,
Martin I really appreciate your suggestion on PointStacker. Unfortunately I
can't try it until Monday now. The page didn't specify if you could
aggregate conditionally (e.g. group by) which would be really useful,
because then features could retain the right symbology. It seems like it was
Additional information in case it helps:
The issue may be related to either the names of the Shapefiles I am
configuring or the number of them ( 350).
Shapefiles have a naming structure like

I think I have a legitimate reason to ask the same question so hopefully
there is an easy way to do this.

ask the user to login using a GeoServer
In a recent demo a developer in my company saw that we were using CQL filters
in GeoServer, and saw how similar the syntax is to SQL, then started
worrying about SQL / CQL injection. I assured him that as CQL filters are
exposed by default I would be very surprised if this was even possible

Christian, I feel we're approaching an 'agree to disagree', but I'm curious -
where are the guidelines suggesting that SLDs should only contain one active
style at any scale?
The specification permits multiple FeatureTypeStyle elements for a good
reason - so that you can have multiple 'layers'
I have a layer defined in GeoServer which uses a parametric view to Oracle
(11.2.0.1, with Locator capabilities). The query I use to define the view is
not particularly complex and when I run it directly against the DB it
executes in well under 1 second.
If I request a WMS map from this layer
I have created the following global template for my text/html GetFeatureInfo
response and it's working great with one layer:
{
layer:
{
name: ${type.name?js_string},
features:
[
#list features
I know this is an old thread but I was thinking about how getFeatureInfo
might work under the covers and Andrea's description of layer ordering and
only querying what the user can see is what I would expect to happen.
Regarding most servers just query all the layers without checking what is
Unfortunately it's not always practical to aim for exactly one rule applying
at any scale. For example a roads layer will usually show highways and
residential roads at the same scale.
In my WMS roads layer all road features are contained in a single Shapefile
with an attribute indicating road
There could be multiple problems here, but this is a big one: You set the
SRID to 4326 (WGS 84 Lat/Lon), but the coordinates you provided for your
feature and your DIMINFO array are not using Lat/Lon.
For 4326 to be the correct SRS all X ordinates would be within -180 to +180
and Y within -90 to

I recognise that this is as much an ArcGIS question as it is GeoServer, so I
will put something on the ESRI forums also, but I find the ESRI forums
surprisingly poor for actually resolving ArcGIS problems.
I am connecting ArcGIS (v10, SP3) to a GeoServer (2.1.3) WFS through its

That's great thanks Max, unfortunately I can't test this out until next week
as I'm out of the office and have no remote access, but I'll update this
thread with the outcome.
If this is the issue it suggests the xml validation on configuration reload
should be a bit stricter and more informative.
I'm having trouble understanding how GeoWebCache and GeoServer fit together
when it comes to new GridSets - this may be a bug but I'm not sure.
I have defined a new GridSet which seems fine (no more messages in
GeoServer's log when I reload geowebcache.xml). I found out here:
