[Geoserver-devel] image/gif format not functional in tomcat

Hi all,

Running the wms cite tests for 1.7.1 in tomcat i ran into this issue:

java.lang.NoClassDefFoundError: com/sun/media/imageioimpl/common/LZWCompressor

This seems to occur with any wms getMap request which chooses image/gif as an output format. Example:

http://localhost:8080/geoserver/wms?request=getmap&layers=topp:states&format=image/gif&width=500&height=500&bbox=-180,-90,180,90&srs=epsg:4326&service=wms&version=1.1.1&styles=population

Do the imageio experts have an idea? Can anyone reproduce?

Tested it on my windows box using the Eclipse starter, works fine...
but afaik someone else reported a similar problem already.
It seems to occur on Mac only, and only with Tomcat 6.
Try downgrading to Tomcat 5 maybe?

Cheers

It may be a classloader issue ... where are the imageio jars located
on your configuration? Have you more than one version of imageio
deployed somewhere?
