Hi Folks,I sent a message on this subject to the support-thredds address at Unidata, but it occurred to me that this might be a "community question" that the pyDAP developer might want to weigh in on so here goes...
When I attempt to read this catalog: http://climate.llnl.gov/dap/ipcc4?thredds (which I believe is being automatically generated by the pyDAP server) I get the following error:
Exception in thread "Thread-11" java.lang.NullPointerException at thredds.catalog.InvCatalogRef.<init>(InvCatalogRef.java:70)at thredds.catalog.parser.jdom.InvCatalogFactory10.readCatalogRef(InvCatalogFactory10.java:153) at thredds.catalog.parser.jdom.InvCatalogFactory10.readDatasetInfo(InvCatalogFactory10.java:266) at thredds.catalog.parser.jdom.InvCatalogFactory10.readDataset(InvCatalogFactory10.java:182) at thredds.catalog.parser.jdom.InvCatalogFactory10.readCatalog(InvCatalogFactory10.java:135) at thredds.catalog.parser.jdom.InvCatalogFactory10.parseXML(InvCatalogFactory10.java:89)

at java.lang.Thread.run(Unknown Source)I have tried both my own code which I know uses 2.2.16 and the toolsUI that launches from http://www.unidata.ucar.edu/software/netcdf-java/v2.2/webstart/netCDFtools-2.2.jnlp.
I could not get the validation form at http://motherlode.ucar.edu:8080/thredds/validateForm.html to work against this URL either.
Any ideas? Thanks, Roland =============================================================================== To unsubscribe thredds, visit: http://www.unidata.ucar.edu/mailing-list-delete-form.html ===============================================================================
