[bioontology-support] Java/Jena example 500 error

[Ray Fergerson]

The link below appears to work now and downloads a file (NDDF.ttl). Can
you confirm? Have I misunderstood what you want?

Here's an example of one from this url:
http://bioportal.bioontology.org/ontologies/NDDF

 

Here's the link with the API key:

Sorry but I am still a bit lost. What keys are you referring to that are
associated with the ontology download links? Where do you see these links?
Are they in some sample code that we provide?

Yes, there are keys associated to the ontology download links. If I use
one of those then I get data using the sample java programs.

Why do you say this? If you use someone else's api key does it work?

Ok, thank you for your reply.


I actually think it's my API key that is the problem:

Our expert on this is half-way around the world this week. He should be
able to respond next week.

Hello,

I am trying to run the java file using Jena below after supplying my
apikey but I keep getting an HTTP 500 error. I also tried adding a query
parameter but get the same error.

 

Thanks,
Michael
