This is the 3rd time I have seen this exact error come up in two days. I
am starting to think that this might not be a coincidence.
Davis, Rob, Lena: can you tells us what version of geoserver you are
using? Thanks.

Hi,
We implemented our own test datastore in geotools, and are trying to
make it work via WMS using GeoServer. WFS seems to work without a
hitch using GeoServer.
Using WMS -- however..the following query:
http://localhost:8080/geoserver/wms?version=1.3.0&request=GetMap&layers=teleatlas:RoadElement&BBOX=5.7,49.4,6.5,50.1&srs=EPSG:4326&width=300&height=300&format=image/gif&STYLES=simple_road
produces a blank map image, and eclipse debugger reports the following:
[SEVERE] org.geotools.renderer.lite.StreamingRenderer$DefaultRenderListener
- Error transforming bbox
[SEVERE] org.geotools.renderer.lite.StreamingRenderer$DefaultRenderListener
- Exception rendering layer [EMAIL PROTECTED]
Tracing the debugger in eclipse,
org.vfny.geoserver.wms.responses.produceMap() calls:
renderer.paint(graphic, paintArea, at); at line 244 in produceMap()
I did an SVN co on the 2.1.x branch of GeoTools and imported into
eclipse, but my debugger's execution pointer is not correct when I
step into org.geotools.renderer.lite.StreamingRenderer so I'm having
some trouble finding the problem.
It does seem this problem has been experienced by other users before.
Is it possible that someone on the list might help explain what may be
going wrong?
The try block where the exception is caught reads:
// Then create the geometry filters. We have to create one for each
// geometric
// attribute used during the rendering as the feature
may have more
// than one
// and the styles could use non default geometric ones
CoordinateReferenceSystem sourceCrs =
currLayer.getFeatureSource().getSchema()
.getDefaultGeometry().getCoordinateSystem();
if (sourceCrs != null && !sourceCrs.equals(destinationCrs)) {
// get an unprojected envelope since the feature
source is operating on
// unprojected geometries
transform =
operationFactory.createOperation(destinationCrs,sourceCrs).getMathTransform();
if (transform != null && !transform.isIdentity()) {
// Envelope eee= JTS.transform(envelope,
transform);// this is the old way
//10 = make 10 points on each side of the bbox
& transform the polygon
envelope = JTS.transform(envelope,
transform,10); // this will usually be a "bigger" bbox
} else
transform = null; //reset transform
}
Filter filter = null;
if (!isMemoryPreloadingEnabled()) {
BBoxExpression rightBBox =
filterFactory.createBBoxExpression(envelope);
filter = createBBoxFilters(schema, attributes, rightBBox);
} else {
filter = Filter.NONE;
}
// now build the query using only the attributes and
the bounding
// box needed
DefaultQuery q = new DefaultQuery(schema.getTypeName());
q.setFilter(filter);
q.setPropertyNames(attributes);
query = q;
I'm just looking for some helpful pointers on what to try next from
any veterans familiar with this area of the code --
Thx...
Davis
