Blender doesn’t export skeleton.xml only material and mesh some times please .

You need to check which blender version is supported by the blender2ogre exporter addon. Open .py file and check the comments at the biginning of the file.
You can download others versions from http://code.google.com/p/blender2ogre/downloads/list

I was using blender 2.63a without any problem.

Yeach ! Model was exported with Blender 2.63 . I have made a little mess with armature an uv’s so finaly - two testing legs did come to Jmonkey with no texture and no animation. They are red. But I think this is subject of some new post. Thank’s for tip with blender.

it seems that the ogre exporer has been taken over by somebody else. Look at the last post. There is a link to a bitBucket repo with a version fro blender 2.66 (didn’t test it though)

The ogre exporter for Blender 2.66 after first attemp did fail to export material file . I am going check it a few more times with some other models. I don’t know if blender version 2.66 and 2.66a are equal for ogre exporter ?
