What steps will reproduce the problem?

  1. For comparison, go to http://mmisw.org/ont/ioos
  2. Go to http://mmisw.org/ont/cuahsi

What is the expected output/behavior? A simple list of CUAHSI vocabularies, like the one for IOOS. (Problem originally identified by Emilio Mayorga, who prefers this presentation of information for some customers to the more complete information available at http://mmisw.org/orr/#ba/cuahsi. )

What do you see instead? A 500 error:

HTTP Status 500 -
type Exception report
message
description The server encountered an internal error that prevented it from fulfilling this request.
exception

java.lang.NullPointerException

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.40 logs.

What version of the product are you using? (You can see the version at the bottom of the ORR page.) ORR Portal 2.1.2 (201410080025)

If relevant, please attach the file you were working on (for submission of new ontology, text for import in the vocabulary interface, etc.).

If possible and relevant, please provide a screen shot showing the problem.

Please provide information about your browser and version (Firefox, Safari, Chrome, IE, etc.), operating system, etc. Google Chrome on Mac Version 38.0.2125.122

If this is easy to fix, it could be kind of valuable to fix, in terms of Emilio using ORR features to communicate with customers.

If it's hard, then it isn't critical.

Seems like a straightforward fix, which I'll try to complete shortly, but deployment may be delayed as I'm not able to VPN the server at the moment.

Fixed in Ont service 2.1.3. Testing pending once the new version can be deployed. Will add a note when that happens.

Status: Fixed

Version 2.1.3 (201412021018) deployed and fix verified. http://mmisw.org/ont/cuahsi now shows a list of about 20 ontologies.

Note: one of the entries in the list is: http://mmisw.org/testing/CUAHSI/TEST_aquabiocompound which seems to have triggered the NPE in the previous version, most likely because it is actually a re-hosted entry that happens to follow the MMI URI structure. Look into this a bit more when time permits.

Status: Verified

Here is the issue entered for the observation above: Issue 334 (github would have cross-referenced it automatically ;)

graybeal commented 9 years ago

Reopening issue because symptoms are back. We need to decide whether to fix it or let it go.

It occurs to me the problem may have been caused by my addition of a test CSDMS vocabulary, trying to make it follow our pattern although it is remotely hosted. That would be https://mmisw.org/orr/#http://www.isi.edu/ikcap/geosoft/ontology/csdms, more than likely. Deleting the offending ontology is a short-term workaround.
