Hi all,

We are working on installing and configuring a Thredds server at http://ers.cmima.csic.es/thredds. We have two questions about the viewers:

  1. When a user clicks on “Integrated Data Viewer (IDV) (webstart)” (for example at http://ers.cmima.csic.es/thredds/catalog.html?cmd=subset&catalog=http://ers.cmima.csic.es/thredds/catalog/ers/2001/08/25/catalog.xml&dataset=ers/2001/08/25/20010825.1343.n16.nc.bz2), webstart loads IDV but it doesn't load directly the 20010825.1343.n16.nc.bz2 file. Are we missing something?

  1. We are trying to add another external viewer. According to http://www.unidata.ucar.edu/projects/THREDDS/tech/tutorial/Viewers.html, fisrt of all we have to implement the Viewer interface. The question is: where is this interface? At the documentation it can be read that “Your class must implement the thredds.servlet.Viewer interface” but where can we find “thredds.servlet” package?

Thanks in advance,
