Hi Joseph,
The point is that when you declare a slot as PRIMITIVE then the type
must be a primitive type i.e. one of Ontology.STRING_TYPE,
Ontology.INTEGER_TYPE....).
In any case I would strongly suggest migrating to the new support for
content languages and ontologies (jade.content.xxx) that more powerful
and better documented (see the tutorial on the JADE site). The old one
is going to be deprecated in one of the next versions.
Bye
Giovanni

Subject: [jade-develop] passing a Vector in a slotDescriptor
Hi all,
I have little trouble passing an object of vector type in a slot
Descriptor.
I have used the Ontology.ANY_TYPE since I could not get a vector
primitive
type as follows:
Ontology myInstance=new DefaultOntology();
..
..
..
myInstance.addRole("parcel",
new SlotDescriptor[]{
new
SlotDescriptor("parcelName",Ontology.PRIMITIVE_SLOT,Ontology.ANY_TYPE,On
tolo
gy.M),
new
SlotDescriptor("Deliverloc",Ontology.PRIMITIVE_SLOT,Ontology.ANY_TYPE,On
tolo
gy.M),
new
SlotDescriptor("Priority",Ontology.PRIMITIVE_SLOT,Ontology.ANY_TYPE,Onto
logy
.M)
},ParcelDetail.class);
It compiles fine, but when I try to test, I get the following exception:
jade.onto.OntologyException: 4 Wrong class: the primitive slot
parcelName is
o
type class java.util.Vector, but must be a subtype of java.lang.Object.
at
jade.onto.DefaultOntology.checkClass(DefaultOntology.java:559)
at jade.onto.DefaultOntology.addRole(DefaultOntology.java:118)
at ParcelOntology.initInstance(ParcelOntology.java:73)
at ParcelOntology.<clinit>(ParcelOntology.java:55)
at DeliveryAgent.registerWithDf(DeliveryAgent.java:218)
at DeliveryAgent.setup(DeliveryAgent.java:117)
at jade.core.Agent.run(Agent.java:1509)
at java.lang.Thread.run(Unknown Source)
I will appreciate any advice.
Thanks Joseph
