Subject RE: Creating an IAsset in code from a context image
Date Mon, 05 Sep 2005 11:05:17 GMT
Hi,

Not sure if I'm missing something, but I can't find a class called
'ContextResourceLocation' in the Tapestry (4.0) framework ...?

Also, the interface IResourceLocation (which I'm assuming is implemented
by this?) doesn't seem to be included in the online Javadoc, although it
exists in the project.

public IAsset createAsset(ServletContext context, String path) {
  return new ContextAsset( new ContextResourceLocation(context, path),
null); }

there you go.
