[Geoserver-users] Geoserver extension plugin problem when deployed on different platfrom

[tam_tran]

I followed geoserver imagepyramid plugin to write the plugin for reading our
proprietary pyramid data. The code was developed on Ubuntu platform using
Eclipse IDE and java 1.7. I built the jar file and dropped it onto the
WEB-INF/lib of Geoserver-2.5. When I restarted geoserver and clicked
"Add New Store", I saw my extension showed up under the "Raster Data
Sources" and was able to add the store and publish the layer. However, when
I copied the JAR file onto the WEB-INF/lib of the same geoserver version on
CentOS platform and restarted Geoserver, I got the following errors. I have
no ideas what was wrong. My code is pure Java and it only depends on
geotools.
Not sure why Spring could not find the
org.geoserver.data.util.CoverageStoreUtils class. I inspected the
gs-main-2.5.jar and the class is in there.

Dear Tam,
I would stop Tomcat and clean the tmp and work directories then I will retry.
In any case I would suggest you create also an extension for GeoServer
likewise the ImagePyramid one and avoid
moving files manually but you rather let geoserver build the war for you.

Hi Simone,

Thanks for you response. The problem is most like caused by the jdk version
that I used to build the plugin jar. I built the jar using jdk 1.7 but the
JDK on the CentOS machine is 1.6. Anyway, I will take care of that later.
Right now I just try to make it work. When I previewed my data on the Layer
Preview, I saw the image returned from my code does not align correctly with
the background image which is the world image. I did some debugging and
found out that the PlanarImage returned from my code is actually correct but
somehow when input it to make the GridCoverage2D, it was distorted. I don't
really understand the internal of Geoserver and therefore I need help from
you. I saw you are the author of most Geoserver plug-ins and hope that you
can help me. I attached the source code of my plugin for you to look at and
hopefully you can tell me what was wrong. Look at the following line in the
loadRequestedTiles of the VistaMapCacheReader class where I where I generate
the BufferedImage. Let me know if you need more information.
    BufferedImage bi = VistaMapCacheUtil.serviceMapRequest(mapLayer, bbox,
dim.width, dim.height, true, Color.blue);
      ImageIO.write(bi, "png", new File("/tmp/vistamapcache.png"));

Ciao Tam,
if this is going to be an open source plugin (I mean donate to
GeoServer or GeoTools). I might try to spare some time to look into
what your problem is (no promise),
otherwise I won't.

That said, I would suggest to look into how you georeference the
gridcoverage you produce since if there is a misplacement the
reason might be that you reporting a wrong gridtoworld transformation.

Hi Simone,

Thanks for you response. The problem is most like caused by the jdk version
that I used to build the plugin jar. I built the jar using jdk 1.7 but the
JDK on the CentOS machine is 1.6. Anyway, I will take care of that later.
Right now I just try to make it work. When I previewed my data on the Layer
Preview, I saw the image returned from my code does not align correctly with
the background image which is the world image. I did some debugging and
found out that the PlanarImage returned from my code is actually correct but
somehow when input it to make the GridCoverage2D, it was distorted. I don't
really understand the internal of Geoserver and therefore I need help from
you. I saw you are the author of most Geoserver plug-ins and hope that you
can help me. I attached the source code of my plugin for you to look at and
hopefully you can tell me what was wrong. Look at the following line in the
loadRequestedTiles of the VistaMapCacheReader class where I where I generate
the BufferedImage. Let me know if you need more information.
                BufferedImage bi = VistaMapCacheUtil.serviceMapRequest(mapLayer, bbox,
dim.width, dim.height, true, Color.blue);
                        ImageIO.write(bi, "png", new File("/tmp/vistamapcache.png"));

Hi Simone,

Thanks for you response. Unfortunately, it is not going to be an open
source plugin because of the format of the dataset. That said, can you help
me understand more of the gridToWorld transformation? Below is how I
compute the gridtoworld transformation:

orginalEnvelope - -180,-90 180,90
SRS - EPSG:4326
originalGridRange - the width/height of the highest resolution image.
final GridToEnvelopeMapper mapper = new
GridToEnvelopeMapper(originalGridRange, originalEnvelope);
      mapper.setPixelAnchor(PixelInCell.CELL_CENTER);
      this.raster2Model = mapper.createTransform();

Is there any wrong with the above?

Regards,
Tam
