[Geoserver-devel] ImageMosaic stopped working in

Just_van_den_Broecke · December 15, 2009, 12:37pm

Hi,

When upgrading from nightly trunk 2009.10.29 to nightly 2.0.x 2009.12.15 my existing ImageMosaic layers (dirs with GeoTiffs) stopped working, nor am I able to create new ImageMosaic layers. I get multiple exceptions of which this is the main one IMO (strange that EsriAsciiGridRaster is called):

15 Dec 12:03:08 ERROR [class org.geotools.gce.imagemosaic.ImageMosaicUtils] - Unable to build mosaic

I also found this error in http://pastebin.com/d2d1ab6fd . Found on Mac OSX (.DS_STORE maybe?). Switching back to trunk 2009.10.29 makes ImageMosaic fully working again. Any idea or an existing ticket I may not be aware off ? best,

Dear Just,
do you have any chance to share part of your sample data to reproduce the issue?
The pastebin link found by you have been posted yesterday by a colleague of mine having that issue.
However, he told me that he had a dirty installation since he had duplicated imageio-ext jars in both geoserver/WEB-INF/lib as well as on its JAVA_HOME/jre/lib/ext. Cleaning the machine (by eliminating duplicated jars reachable by the classloader), he solved the issue.

Please, let me know.
Best Regards,
Daniele

Dear Daniele,

Yes I can send you a link but probably this is not neccessary anymore. I think the entire issue boils down to the fact that ImageMosaic fails after redeploy in a running Tomcat instance. I tested with several versions (2.0.0a, 2.0.x-2009.12.15 and trunk-2009.12.15) but always ImageMosaic fails after a redeploy.

I am mostly using hot-deploy, building/deploying a geoserver .war in Tomcat Ant using a configured GS version. This always works fine for most GS/GT functions but appearantly not for ImageMosaic. Maybe a class-unloading issue. I don't know if it is a requirement that GS should be redeployable.

Thanks, and best regards,

--Just
