import problems : glm, uno, org.w3c.dom

[Heslau]

Hello guys,

I've seen the post about the following problem : "The import glm cannot be resolved"

and I have the same issue + a couple more. The import glm cannot be resolved The type org.w3c.dom.Element is not accessible

I'm using Eclipse and experimenting with jogl (or at least trying to) but I failed to have the first tutorial working until now. If anyone knows why and how it may happen, help would be welcome :/
