Re: [netcdf-java] DTD warnings from THREDDS during app startup

Hi again Phil,

Sorry for the delay. These old DTD and schema files got "cleaned up" in our source tree and are currently not getting packaged as resources in the netcdf-4.3.jar file. They are still available at the URLs shown in your error message. So, not sure why they didn't get resolved. Where you off-line at the time?

Until we can review the code and get this figured out in a more thorough manner, I'm going to get these and any other "cleaned up" DTD/schema files back to being packaged in our distribution. Should be in the next release (4.3.16).

Hi Phil,

[About to run out but wanted to get you a quick response.]

Both the QueryCapabilities and the CatalogGenConfig XML dialects are
pretty old and no longer being developed (and never widely used). There
is still code in the netCDF-Java library that deals with them and
probably needs to be deprecated. I'm not sure what would have changed
between 4.2 and 4.3 to cause this error. I'll take a closer look later
today or tomorrow.

Hi folks,

I'm getting the following THREDDS -related warnings when I run the
Panoply application (v3.1.5) against netcdf-java 4.3.13.

  *** FAILED to map entity
at /src/main/archive/schemas/thredds/queryCapability.0.4.xsd or remotely
at _

  *** FAILED to map entity
at /src/main/archive/schemas/thredds/CatalogGenConfig.0.5.dtd or

These warnings don't stop the application from starting up (eventually)
but they do cause it to hang for a few minutes. Presumably some piece of
code is trying to find and parse DTD documents in the advertised locations.

This problem doesn't afflict Panoply 3.0.5, which I see uses

Can anyone shed any light on what's going on here? I'm stumped.

FYI, I'm using Java 1.6.0-33 on RedHat Enterprise Linux v6.
