Java & Scratch on XO

[John Maloney]

Hi, Tomeu.

Thanks for your reply. It's great that there is a way to handle this!

I took a quick look at the EToys .xo bundle and did not see a  
mimetypes.xml file. However, I did notice that EToys lists a lot of  
mime types in it's activity.info. What I don't see is how the system  
would know what file extension to associate with a type like  
"application/x-squeak-project". Is that what the mimetypes.xml is for?  
Do you know of any other activity that uses a mimetypes.xml file that  
would be a good model for Scratch?
