title: error import netcdf GeoServer
body: <p>I'm trying to import a netcdf file into geoServer, and I get the following message:</p>
  
  <pre><code>"Could not list layers for this store, an error occurred retrieving them: Failed to create reader from file:workspaces/hugo/wrf15_all.nc and hints null"
  </code></pre>
  
  <p>What has already been done,
  I've already downloaded other netcdf to test the integrity of my file.</p>
  
  <p>I put the file inside the geoserver's data_dir folder, but without success.</p>
  
  <p>I changed the server to tomcat7, imported the .war file and got the same error.</p>
  
  <p>The netCdf and Grib pluguins have been downloaded from the following address:
  <a href="http://geoserver.org/release/2.11.2/" rel="nofollow noreferrer">http://geoserver.org/release/2.11.2/</a></p>
  
  <p>I am putting the log for better analysis.</p>
  
  <p>Any help will be of great value.
  I keep trying to solve the case, but this is my second day with the geoserver.</p>
