Daniele -
Thank you for your reply, which serves to remind me that I should
have posted the solution to the list, because I was able to resolve this.
I realized after going through the documentation that the ImageMosaic
plugin would need write permission to the mosaic directory. Once I gave the
tomcat user write permission to the directory, creating the mosaic worked.
I would make two suggestions for the documentation/implementation of
the ImageMosaic plugin. One, that write failures to the mosaic directory
have a clear error message. As you can see from my original post, there
were no hints. Two, creating an image mosaic and then viewing it caused
Geoserver to throw 'too many open files' errors. A bit of documentation on
how to increase the limit on the number of open files would be a good
addition to the ImageMosaic docs. Once I figure out all of the steps, I
would be glad to contribute that.
