Were you connected to the internet at the time you did this? Nothing we can really do about that :( Well yes I was connected. I even checked the file by opening the file with IE.

It's wrong. Quite franky, I would not trust _anything_ in those examples they're all wrong and far from spec compliant, even within the latest draft specs. Firstly, all those examples have the wrong PUBLIC ID. Next, the name attribute of the component must be one of the component names defined in the X3D specification. The FCD draft that was sent to ISO a week or so ago can be found here: http://www.web3d.org/TaskGroups/x3d/x3d_spints.html This is only the abstract specification, but it should at least give you the formal names of all of the components. > After removing all the <meta> tags I had to add "" to the description of > the Viewpoint ('"hello, world!"') and the type of the NavigationInfo > ('"EXAMINE ANY"') > I had to remove the <NavigationInfo> tag because the navigation state was > unknown. Correct. This is another error in the examples. The type attribute is an MFString, which means when you want to provide more than one value, you need to quote each string separately in the attribute value. Right now, the way that example is written the type attribute has the value "EXAMINE ANY", which is not valid. What you really need to say is "EXAMINE" "ANY", so the real navInfo should be: <NavigationInfo type='"EXAMINE" "ANY"'/> > I also had to change the X3D profile to "Immersive" to get the <Text> > working. Correct. Text doesn't appear until that profile. If you wanted to include the text component and use a lower profile, you can use the <component> tag like you saw in the above example. > Finally I got a white sphere with the text under it but I got this > Exception: > Warning: IO Error reading external file http://www.web3d.org > :80/TaskGroups/x3d/translation/examples/earth-topo.png > www.web3d.org > java.net.UnknownHostException: www.web3d.org Eeeck.
