You would have to create a special shader for this. Basically you need reflection and the light scattering effect, the reflection map example shows how you can do the reflection, then looking the source of the light scattering shader would be the first step towards creating the scattering effect as well.
this link does not work :

You have all tests available when you create a new JmeTests project. So you got this link from the wiki? Or is this some “links that dont work” game I dont get?
