[Geoserver-users] Newbie - 1.6.1 WFS version question

Jonathan_Lister · March 13, 2008, 10:12am

Platform: Windows XP, Sun Java 1.6.0_04, GeoServer 1.6.1 war added to
GlassFish v2-b58g.
All GeoServer demo's run fine.

Created new Data Store to connect to Oracle 10g Enterprise Edition
10.2.0.3.0, connecting as a test user that owns a few demonstration tables.

Created a new Namespace, vai

Created a new FeatureType OraGIS:locator which is linked to VT_LOCATOR table
and vai Namespace

WMS requests for vai:locator works at first attempt - very nice

WFS is more problematic though:
GetCapabilities includes a section like this which looks OK to me:
<FeatureType>
  <Name>vai:locator</Name>
  <Title>VT_LOCATOR_Type</Title>
  <Abstract>Generated from OraGIS</Abstract>

</FeatureType>

DescribeFeature also looks OK:

BUT, If I change just the first line of the request from wfs 1.1.0 to wfs
1.0.0 it all suddenly (well actually not so suddenly - there was about a day
of trying just about every other permutation and combination ..) springs

...

I suspect that I haven't properly set the featureType up - maybe something
to do with the nameSpace? or maybe I am making a stupid mistake in
requesting WFS 1.1.0 ?

Hi Jonathan,

Thanks for the complete bug report. Its not obvious to me what is the problem. If you could perhaps change logging to GEOTOOLS_DEVELOPER_LOGGING and include the log that would be helpful.

Also, could you try the following request and see if it produces the same result. Thanks.

I suspect that I haven't properly set the featureType up - maybe something
to do with the nameSpace? or maybe I am making a stupid mistake in
requesting WFS 1.1.0 ?

I ran your test, and also tried a WFS connection from uDiG (see below) ..

Yes, the request below gives the same result:

Changing the featureType's schema base from '-' to gml:AbstractFeatureType
didn't bring any change either.

Hi Jonathan,

Thanks for the complete bug report. Its not obvious to me what is the
problem. If you could perhaps change logging to
GEOTOOLS_DEVELOPER_LOGGING and include the log that would be helpful.

Also, could you try the following request and see if it produces the
same result. Thanks.

Hi Jonathan,

Yes, its possible that its your data that the gml3 encoder can not handle. Is there any chance you can make a dump of your table available? I admit, Oracle is not my forte but i can try setting it up on my end to see if i can replicate the problem.

I upgraded to GeoServer 1.6.2a, re-configured nameSpace, dataStore,
featureType from scratch, created a new geometry table with the minimum
columns and just a couple of rows - still get the same result, i.e. WFS
1.0.0 request is OK, but WFS 1.1.0 doesn't work unless GML2 is specified for
outputFormat. Does this imply that I can't use Oracle with GeoServer / WFS
1.1.0 / gml3?

I guess I'll have to try same data in postGIS next ..

CREATE TABLE test_table (
  test_id NUMBER PRIMARY KEY,

Before you try that out, I have a hunch about what's going on.
Can you try one thing for me?

CREATE TABLE test_table (
  test_id NUMBER PRIMARY KEY,
  test_name VARCHAR2(32),
  test_geom SDO_GEOMETRY);

...

CREATE INDEX test_spatial_idx
ON test_table(test_geom)
INDEXTYPE IS MDSYS.SPATIAL_INDEX;

With this setup there is no way GeoServer can be sure of what
type of geometry is in that column, and in fact the describe
feature type results in:

<xsd:element maxOccurs="1" minOccurs="0" name="LOCATOR_GEOMETRY"
nillable="true" type="gml:GeometryPropertyType"/>

I'm not sure about it, but it may be that the GML3 encoder
does not work under these conditions (generic geometry type).
If so, we should fix it, since it's actually possible to stop
a mix of different geometry types in the same geometry column
in Oracle.

Yet, I see your data are all points. If that's the case,
recreate your index to enforce the geometry type

CREATE INDEX test_spatial_idx
ON test_table(test_geom)
INDEXTYPE IS MDSYS.SPATIAL_INDEX PARAMETERS ('SDO_INDX_DIMS=2 LAYER_GTYPE="POINT"')

This way Oracle will enforce point type and GeoServer will
use this information in the feature type reverse engineering,
declaring the LOCATOR_GEOMETRY as Point type... and I guess
GML3 output will work that way too.

Ah, I also have a curiosity. WFS 1.1/GML3 are relatively new
and there is quite a lack of clients able to speak that
version of the protocol, in fact I know none...
All the WFS clients I know of do use WFS 1.1 and GML2, do
you know of any that already use WFS 1.1?

Cheers
Andrea

"stop a mix"... what was I thinking???
that should have been "put a mix"

Yes, OpenJUMP with WFS plugin. The history of that plugin is that an
previously existing plugin was further developed against Geoserver
1.5 (WFS 1.0 + GML2), and it works fine against it supporting menu based
filter building for both attribute and spatial queries, editable http POST
query preview window. An undocumented feature is that it can also be used
in standalone mode when the GML returned from the server can be stored
into file even if it has something off that prevents it to be parsed
to OpenJUMP GIS as a map. Only problem that I remember right now that
was left was some error in date/time type attribute parsing when
there was Oracle spatial on the background. My knowledge comes only from
being involved in ordering the work and making acceptance testing but about
technics behind I know only that is is Java and utilises deegree libraries.

After that WFS plugin has been developed further to support WFS-T
1.1 with GML3 with deegree. Unfortunately the plugin does not work
against Geoserver WFS 1.1 because of the way that Geoserver is using
in advertising the coordinate reference system.

I believe that not very much work would be needed to make OpenJUMP plugin to
support even WFS-T 1.1 with Geoserver, but most efficiently the development
work would be if done in co-operation with the deegree folks.

in standalone mode when the GML returned from the server can be stored into file even if it has something off that prevents it to be parsed to OpenJUMP GIS as a map. Only problem that I remember right now that was left was some error in date/time type attribute parsing when there was Oracle spatial on the background. My knowledge comes only from being involved in ordering the work and making acceptance testing but about technics behind I know only that is is Java and utilises deegree libraries.

After that WFS plugin has been developed further to support WFS-T 1.1 with GML3 with deegree. Unfortunately the plugin does not work against Geoserver WFS 1.1 because of the way that Geoserver is using in advertising the coordinate reference system.

Hum, interesting... why is that? The way we report the srs (you mean
the urn form?) is mandated by the standard. There is also the axis flipping issue, that as well is mandated by the standard (for more info
on the axis order issue see here: http://geoserver.org/display/GEOSDOC/2.+WFS)

I believe that not very much work would be needed to make OpenJUMP plugin to
support even WFS-T 1.1 with Geoserver, but most efficiently the development work would be if done in co-operation with the deegree folks.

Eh, we have quite a bit of community clash here, and also I'm not an OpenJump user, but I'm interested in any collaboration that brings
a new client to the mix, the more, the merrier.

Cheers

Yes, OpenJUMP with WFS plugin. The history of that plugin is that an
previously existing plugin was further developed against Geoserver
1.5 (WFS 1.0 + GML2), and it works fine against it supporting menu based
filter building for both attribute and spatial queries, editable http POST
query preview window.

Hi Andrea,

The following information would belong better to OpenJUMP web page, but if you are really going to have a look at OpenJUMP WFS plugin this will help you to get a quick start. Anyway this message has a connection to Geoserver because the plugin was developed against Geoserver and it works well as non-transactional WFS 1.0 client with Geoserver. I believe the same is true with deegree as well but unfortunately not with UMN MapServer WFS.

-Jukka Rahkonen-

Installation instruction follows:

1.Download and install OpenJUMP from http://openjump.org. I recommend the weekly build.
2.Download WFS plugin. The link from OpenJUMP page leads to
http://sourceforge.net/project/showfiles.php?group_id=118054&package_id=150819
This plugin supports actully just non transactional WFS 1.0. It works well with Geoserver WFS 1.0. It there should be some errors in parsing, the 0.3.0 version of the plugin is a bit more robust in parsing. Actually it is parsing all attribute types to strings.

Another place to load WFS plugin for OpenJUMP is
https://wiki.deegree.org/deegreeWiki/deeJUMP?action=AttachFile&do=get&target=wfsplugin.jar

The latter one is the one supporting also WFS-T 1.1.0, but not with Geoserver at the moment because of the urn format used in projection naming. Axis flipping in WFS 1.1.0 should not be a problem.
For more information read https://wiki.deegree.org/deegreeWiki/deeJUMP

Installation instructions for basic use can be found from the previous addresses. Basically all that is needed is to download the jar-files and insert them to correct directories. After that the WFS plugin will be available through OpenJUMP GIS.

It is possible to run WFS plugin also as stand alone. It gives an extra feature to capture the response from the WFS server before it goes to parser. I have found this valuable for debugging. This has been on undocumented feature so far, so here are some hints about how to use it.

To start WFS-plugin as stand-alone make first a normal plugin installation because some of the OpenJUMP jars will be needed. Then define a classpath to include all WFS plugin jars and jts, jump-api, and logging jars from OpenJUMP directory. Here is a Windows batch file that starts the plugin for me. Other users will need to edit some jar names to suit the reality.

set LIB= openjump/lib
set CLASSPATH=%LIB%/ext/commons-codec-1.3.jar;%LIB%/ext/commons-httpclient-2.0.2-deegreeversion.jar;%LIB%/ext/commons-logging.jar;%LIB%/ext/deegree2.jar;%LIB%/ext/vecmath.jar;%LIB%/ext/wfsplugin.jar;%LIB%/jts-1.7.2.jar;%LIB%/jump-api-20070503.jar;%LIB%/log4j-1.2.8.jar

Before you try that out, I have a hunch about what's going on.
Can you try one thing for me?

CREATE TABLE test_table (
  test_id NUMBER PRIMARY KEY,
  test_name VARCHAR2(32),
  test_geom SDO_GEOMETRY);

...

CREATE INDEX test_spatial_idx
   ON test_table(test_geom)
   INDEXTYPE IS MDSYS.SPATIAL_INDEX;

With this setup there is no way GeoServer can be sure of what
type of geometry is in that column, and in fact the describe
feature type results in:

<xsd:element maxOccurs="1" minOccurs="0" name="LOCATOR_GEOMETRY"
nillable="true" type="gml:GeometryPropertyType"/>

I'm not sure about it, but it may be that the GML3 encoder
does not work under these conditions (generic geometry type).
If so, we should fix it, since it's actually possible to stop
a mix of different geometry types in the same geometry column
in Oracle.

Yet, I see your data are all points. If that's the case,
recreate your index to enforce the geometry type

CREATE INDEX test_spatial_idx
     ON test_table(test_geom)
     INDEXTYPE IS MDSYS.SPATIAL_INDEX PARAMETERS ('SDO_INDX_DIMS=2
LAYER_GTYPE="POINT"')

This way Oracle will enforce point type and GeoServer will
use this information in the feature type reverse engineering,
declaring the LOCATOR_GEOMETRY as Point type... and I guess
GML3 output will work that way too.

Ah, I also have a curiosity. WFS 1.1/GML3 are relatively new
and there is quite a lack of clients able to speak that
version of the protocol, in fact I know none...
All the WFS clients I know of do use WFS 1.1 and GML2, do
you know of any that already use WFS 1.1?

Cheers
Andrea

I'm using Oracle Express, besides that... not sure. I also

I have now moved from Oracle to postGIS (postGIS 1.3.2 on posgtres 8.1);
however I'm still getting the same problems. Must be doing something really
stupid somewhere, but I can't see what - any suggestions really appreciated!

CREATE TABLE test_roads (
road_id INTEGER,
road_name VARCHAR
);

SELECT AddGeometryColumn( 'test_roads', 'roads_geom', 4326, 'LINESTRING', 2
);

ALTER TABLE test_roads
ADD CONSTRAINT geometry_valid_check
CHECK (isvalid(roads_geom));

CREATE INDEX gist_idx ON test_roads USING GIST ( roads_geom );

INSERT INTO test_roads (road_id, roads_geom, road_name)
  VALUES (1,GeomFromText('LINESTRING(5.175501 51.19112, 5.178481
51.19539)',4326),'Jeff Rd');
INSERT INTO test_roads (road_id, roads_geom, road_name)
  VALUES (2,GeomFromText('LINESTRING(4.839782 50.98549, 4.839955
50.98548)',4326),'Geordie Rd');
INSERT INTO test_roads (road_id, roads_geom, road_name)
  VALUES (3,GeomFromText('LINESTRING(4.839955 50.98548, 4.840147
50.98547)',4326),'Paul St');

The featureType looks reasonable in getCapabilities:

Maybe one more clue .. I rectreated entries in the test table with an
explicit SRID, now when making a WFS 1.1.0 request I get a slightly more
meaningful error:

I've tried out the same statemetns you suggested, without setting
the SRS in my geometries (so not the latest version) and WFS GetFeature
seems to work just fine?

Just for fun I also tried running GeoServer under Tomcat (5.5) instead of
GlassFish - and got exactly the same results.

I have now moved from Oracle to postGIS (postGIS 1.3.2 on posgtres 8.1);
however I'm still getting the same problems. Must be doing something
really stupid somewhere, but I can't see what - any suggestions really
appreciated!
