Well, I guess to...

I am getting this exception:
org.opencms.file.CmsVfsResourceNotFoundException: Error reading resource with 
the ID aec33c59-c50d-11dd-a9f2-0015174f605e.

Note that this works:
CmsResource res = cmso.readResource("/sites/my.site.com/data/123/logo.jpg");
//System.out.println(res.getResourceId().toString());


And this not:

CmsResource res = cmso.readResource(new CmsUUID("aec33c59-c50d-11dd-
a9f2-0015174f605e"));

So I guess my user is ok. The uuid I use is the one I saw in the print output 
of the previous example...

Another question came up.... how can I output this CmsResource which is 
image/jpg from the jsp? Is it possible to cast it to a FileInputStream ?
