Hi John, Where can I get the full stack trace? catalogInit.log only has the summary information. Cheers, Jon -----Original Message----- From: John Caron [mailto:caron@xxxxxxxxxxxxxxxx] Sent: 10 July 2010 16:34 To: Jon Blower Cc: thredds@xxxxxxxxxxxxxxxx Subject: java.lang.NullPointerException: Name is null readCatalog(): Exception on catalog=/usr/local/tomcat/content/thredds/idd/atm_mod.xml Name is null log=null catalog java.lang.NullPointerException: Name is null I havent been able to figure out where this is coming from. If anyone sees it again, send me the full stack trace. thanks.
