Re: Aggregation

Hi Rich:
This is a wierd error. 
ucar.nc2.dataset.NetcdfDataset.isDODS(NetcdfDataset.java:305) calls 
java.net.HttpURLConnection. Somehow in your environment, its calling 
ice.net.HttpURLConnection instead, which throws a different Exception than the 
one we expect.

1) can you check with matlab to see if there is a deliberate substitution of 
ice.net for java.net.
2) meanwhile, we will look at a workaround, in case thats the way its supposed to be.

Guys,
When I try to open the same aggregation NcML file with in Matlab, I get the following. Does this indicate that I forgot to import some class from toolsUI-2.2.13.jar? 

import ucar.nc2.dataset.grid.*

Hi Rich-

I built a new nc2.2.jar with John's latest changes.  In
my one test, nothing broke, so it comes with the "big boy"
warranty.

Place the attached jar in your IDV directory and give
your aggregations a try.
