Hello Pauline, John,

Let me know if that helps.

Cheers!

Hi Pauline,

I've run into the same thing. In my case I was able to isolate the problem to aggregations only (NcML or FMRC). Below is my e-mail to thredds-support on Jan 8th with further details. I presume Unidata is still looking into it...

Subject: WMS GetCapabilities broken in TDS 4.3 for all aggregations

To: support-thredds@xxxxxxxxxxxxxxxx <mailto:support-thredds@xxxxxxxxxxxxxxxx>

Hi THREDDS support,

In TDS 4.3, the WMS GetCapabilities URL produces a "HTTP Status 500 - Internal Server Error" for all of my NcML or FMRC aggregation datasets. It works fine for non-aggregated datasets, however. Although GetCapabilities fails for aggregations, I noticed that other WMS requests continue to work fine (GetMap, GetMetadata, GetFeatureInfo), because the Godiva2 viewer continue to produce plots. Can you look at this problem? I have been holding off upgrading to TDS 4.3 in our production server because of this hang up.

Here is the version of TDS I am running in our testbed: Version 4.3.15 - 20121218.1126

Here are links to three aggregated datasets whose WMS GetCapabilities fail:

  * [FMRC] SWAN Apra Harbor Regional Wave Model:
      o 
http://oos.soest.hawaii.edu/thredds-test/catalog/hioos/model/wav/swan/apra/catalog.html?dataset=swan_apra/SWAN_Apra_Harbor_Regional_Wave_Model_best.ncd

  * [FMRC] NCOM Global Ocean Model:
      o 
http://oos.soest.hawaii.edu/thredds-test/catalog/pacioos/ncom/global/catalog.html?dataset=ncom_global/NCOM_Global_Ocean_Model_best.ncd
          + 
http://oos.soest.hawaii.edu/thredds-test/wms/pacioos/ncom/global/NCOM_Global_Ocean_Model_best.ncd?service=WMS&version=1.3.0&request=GetCapabilities
  * [NcML] Big Island Regional Tide Model:
      o 
http://oos.soest.hawaii.edu/thredds-test/idd/tide_mod.html?dataset=tide_bi
          + 
http://oos.soest.hawaii.edu/thredds-test/wms/hioos/tide_bi?service=WMS&version=1.3.0&request=GetCapabilities

Here are links to three non-aggregated (non-temporal) datasets whose WMS GetCapabilities work fine:

  * ETOPO5 Global Surface Relief:
      o 
http://oos.soest.hawaii.edu/thredds-test/idd/bathymetry.html?dataset=etopo5
          +

  * Main Hawaiian Islands Multibeam Bathymetry Synthesis: 50-m Bathymetry:

http://oos.soest.hawaii.edu/thredds-test/idd/bathymetry.html?dataset=hmrg_bathy_50m_mhi
          + 
http://oos.soest.hawaii.edu/thredds-test/wms/hmrg_bathy_50m_mhi?service=WMS&version=1.3.0&request=GetCapabilities
  * Distance to Nearest Coastline: 0.04-Degree Grid: Ocean:

          + 
http://oos.soest.hawaii.edu/thredds-test/wms/dist2coast_4deg_ocean?service=WMS&version=1.3.0&request=GetCapabilities

The log file (threddsServlet.log) has had nothing to report on the errors. The only kind of message that it reports is this:

2013-01-08T10:35:54.216 -1000 [ 1582559][ 147] INFO - threddsServlet - Remote host: 128.171.151.240 - Request: "GET /thredds-test/wms/pacioos/ ncom/global/NCOM_Global_Ocean_Model_best.ncd?service=WMS&version=1.3.0&request=GetCapabilities HTTP/1.1"

    Hi all,

    I'm having trouble with getting a GetCapabilities document using
    THREDDS.

    I'm using THREDDS 4.3.15 - 20121218.1126, and have tried this on
    Java 1.6 and 1.7, running on Tomcat 7.0.27.

    When I browse to the WMS GetCapabilities document, I get a 500
    internal error, and have found the attached error in the
    serverStartup.log

But interestingly, the layers work through the Godiva interface. Has anyone else had this problem? These files use to work under

    THREDDS 4.2.

    An example can be found here:
