Hi all,
I am trying to use the Ontology class in Biojava 1.4rc1 to create terms
and triples, which are automatically persisted using the BioSQL links in
BioJava. Here is my code:
BioSQLSequenceDB db = new BioSQLSequenceDB(dbURL,
dbUser,
dbPass,
biodatabase,
createIfMissing);
Ontology o = db.createOntology("MyOntology","An ontology"); //
Use getOntology to update
Term MyGroup = o.createTerm("MyGroup","My favourite terms.");
Term Boo = o.createTerm("Boo","A fright");
Term ISA = o.createTerm("ISA","Is a");
Term Joke = o.createTerm("Joke","Something funny");
o.createTriple(Boo,Joke,ISA,null,null);
I get the following exception (NB. the ontology does not exist yet but
the database connection is just fine):
Exception in thread "main" org.biojava.bio.BioRuntimeException: Error

Java Result: 1
When I check in the database, I find that the ontology has been created,
and entries made in term for each of the terms, and also an entry has
been made in term for the triple itself. So why the exception? Is it
trying to insert the triple twice?
cheers,
Richard
