[Geoserver-users] Need help: ImageMosaic and GeoTIFFs - finishes with java.lang.NullPointerException

Raja_Kajiev · June 8, 2009, 1:02pm

Hello!

The problem is I can create mosaic form GeoTIFFs, but it can't be displayed.
And the problem can be reproduced at a small project.

What I have:
1) GeoServer 1.7.4 on win32;

2) example 'mosaic_sample' works OK;

3) some GeoTIFFs, created from a larger one (a two images is a minimum
when problem re-creates);

4) the GeoTIFFs itself can be obtained via WMS without problem if
configure them as a stand-alone rasters;

5) I can create new mosaic (with this RTFM
http://geoserver.org/display/GEOSDOC/Using+the+ImageMosaic+plugin )

6) attempt to display that mosaic as map demo finishes in such error
(and nothing is displayed at all):

Looking into the code I see this has been changed after the 1.7.4
release, and probably this issue has been fixed.
Can you try out a nightly build here:
http://gridlock.openplans.org/geoserver/1.7.x/

And see if that works for you?
Cheers
Andrea

Ciao,
as Andrea pointed out this problems has already been fixed, please try
one of the latest nightly builds.

I have to update the mosaic tutorial, but a quick advice is to just
point the mosaic plugin to the directory where your files reside. It
should build the index transparently by itself.

Not sure, but looks like actually I run into this issue:
http://geoserver.org/display/GEOSDOC/ImageMosaic+sometimes+not+showing+tiles
i.e. changing WKT desription in mosaic .prj-file solved problem.

Thnx for the link to nightly builds storage anyway - gonna check'em too.

Checked 060909 build, got the same error when WKT definition in
shp-file differs from definition in GeoServer's epsg.properties.
I can send the data sample or test another build if you can/want to
investigate this problem.

BTW, can you help me with what the "point the mosaic plugin to the
directory where your files reside" exactly mean? What and where should
I tweak?

When setting up the mosaic store, provide the path to the directory
containing the images: GeoServer will generate the shapefile index
and the properties file for you (not sure if it generates just the
properties file when the .shp is already there, to make sure try
also removing the shapefiles).

Cheers
