[jade-develop] jade.content.onto.OntologyException: Non term object in aggregate

Discussion:

Henrique Lopes Cardoso

2014-04-29 08:30:09 UTC

Hi,

The simplest way to describe the problem I am facing is this post:
http://sharon.cselt.it/pipermail/jade-develop/2013q3/019293.html

Now, this seems to be exactly what I am misusing: placing Predicates inside
a List.

The thing is that I have only came across this problem when running my
system under Ubuntu Gnome.

When using Windows no exception is thrown, and predicates flow inside lists
without any problem.

Is there an explanation for this?

Thank you.

Henrique

Hi,

This is really surprising.
Some questions to further investigate:
- Are the code and the jade libraries exactly the same in the 2 cases (Ubuntu and Windows)?
- Is your ontology extending the BeanOntology class or directly the base Ontology class?
- Is the list a java.util.List or a jade.util.leap.List?
- Is your ontology including the SerializableOntology among its base ontologies?
- Can you provide the piece of code that creates the content whose encoding fails in Ubuntu and works in Windows?

Bye,

Giovanni

Yes.

Post by Caire Giovanni

Extending BeanOntology.

Post by Caire Giovanni
- Is the list a java.util.List or a jade.util.leap.List?

The list is a jade.util.leap.List.

Post by Caire Giovanni
- Is your ontology including the SerializableOntology among its base ontologies?

Yes, it is using SerializableOntology.SERIALIZABLE (because I also need to
use a HashMap in another Concept). This is how the ontology constructor
looks like:
MyOntology() {
super(ONTOLOGY_NAME, new Ontology[]{BasicOntology.getInstance(),
SerializableOntology.getInstance()});
...
...
}

Post by Caire Giovanni
- Can you provide the piece of code that creates the content whose
encoding fails in Ubuntu and works in Windows?

Here it is:

Z z = new Z(); // this is a Predicate
z.setX(x); // this is a jade.util.leap.HashMap (that's why I am using
serializable)
z.setY(y); // this is a jade.util.leap.List of Predicates
try {
myAgent.getContentManager().fillContent(response, z);
} catch (CodecException | OntologyException e) {
e.printStackTrace();
}

Now, let me remind you that this works fine under Windows (apparently not
as expected).

Thank you for any hints,

Henrique

I wonder if you have any update on this.
Is the use of SerializableOntology making it work under Windows?
If so, why doesn't it work under Ubunto?

Thank you in advance.

I have an update on this.
Apparently it does not have anything to do with the underlying platform
(Windows/Ubunto). This was a misinterpretation of what was happening. Sorry
for that.

What I did find out is that my project works fine if I use my classes as
such.
The problem arises when I export my classes to a jar file and then try to
use the jar in another Java project. That is when the "No term object in
aggregate" exception is thrown (as explained before).

Any hints?

Henrique

Hi,

Thanks for the update.
Can you also details more the environment you are using when things ?magically? works? I mean: are you working inside an IDE such as Eclipse? If so can you tell me the IDE and how the relevant classes are spread across projects?

Another question: are the Predicate classes (I mean the classes of the objects that you include in the jade.util.leap.List) explicitly registered to the BeanOntology as
add(Pred1.class);
add(Pred2.class);
or through their package as
add("com.acme.rocket.ontology");
?

Hi again,

I understand from your comments that even with the SerializableOntology I
should still be getting the "No term object in aggregate" exception.

Post by Caire Giovanni
Can you also details more the environment you are using when things
?magically? works? I mean: are you working inside an IDE such as Eclipse?

Yes, I am using Eclipse Juno, with JDK 1.7.

Post by Caire Giovanni
If so can you tell me the IDE and how the relevant classes are spread
across projects?

I am using a single java project, and add to the java build path jade.jar,
commons-codec-1.3.jar, among other jar files.

Post by Caire Giovanni
Another question: are the Predicate classes (I mean the classes of the
objects that you include in the jade.util.leap.List) explicitly registered
to the BeanOntology as
add(Pred1.class);
add(Pred2.class);
or through their package as
add("com.acme.rocket.ontology");
?

I am using the package version of add,
using add(this.getClass().getPackage().getName());
My BeanOntology is in the same package as the predicates I want to use.
In any case, I've just tried using the add(Pred1.class) version and the
results are the same.

Thanks.

Henrique

Hi,

The SerializableOntology is used unless the normal ontology is able to manage an object -->
If the class of a Predicate object that you insert in the jade.util.leap.List is registered in the Ontology, the ontology manages it and, since it is a Predicate (that cannot be used in an aggregate) --> it fails.
If on the other hand such class is not registered in the ontology --> the ontology does not manage it --> The SerializableOntology manages it and things will work.

Hi again,

I understand from your comments that even with the SerializableOntology I should still be getting the "No term object in aggregate" exception.

Yes, I am using Eclipse Juno, with JDK 1.7.

If so can you tell me the IDE and how the relevant classes are spread across projects?

I am using a single java project, and add to the java build path jade.jar, commons-codec-1.3.jar, among other jar files.

Another question: are the Predicate classes (I mean the classes of the objects that you include in the jade.util.leap.List) explicitly registered to the BeanOntology as
add(Pred1.class);
add(Pred2.class);
or through their package as
add("com.acme.rocket.ontology");
?

I am using the package version of add, using add(this.getClass().getPackage().getName());
My BeanOntology is in the same package as the predicates I want to use.
In any case, I've just tried using the add(Pred1.class) version and the results are the same.

Thanks.

Henrique

I have an update on this.
Apparently it does not have anything to do with the underlying platform (Windows/Ubunto). This was a misinterpretation of what was happening. Sorry for that.

What I did find out is that my project works fine if I use my classes as such.
The problem arises when I export my classes to a jar file and then try to use the jar in another Java project. That is when the "No term object in aggregate" exception is thrown (as explained before).

Any hints?

Extending BeanOntology.

The list is a jade.util.leap.List.

Yes, it is using SerializableOntology.SERIALIZABLE (because I also need to use a HashMap in another Concept). This is how the ontology constructor looks like:

Thank you for the explanation. So, there seems to be no "magic" going on

Is there a reason for it not to work when packing my classes in a jar file?

Hi,
The SerializableOntology is used unless the normal ontology is able to
manage an object ?
If the class of a Predicate object that you insert in the
jade.util.leap.List is registered in the Ontology, the ontology manages it
and, since it is a Predicate (that cannot be used in an aggregate) ? it
fails.
If on the other hand such class is not registered in the ontology ? the
ontology does not manage it ? The SerializableOntology manages it and
things will work.

Ummmm.... I?m a bit confused: are the Predicate classes registered to your ontology? NOTE that if you have

class A {
private B b;
...
public B getB() {
return b;
}

public void setB(B b) {
this.b = b;
}
...
}

and in your ontology you register A as
add(A.class)

B is automatically registered too.

I've just found out a workaround.
If I add my classes to the ontology using, as mentioned before,
add(this.getClass().getPackage().getName());
I get the exception when exporting the project to a jar file.

If on the other hand, I add individually each Concept/Predicate/AgentAction
using
add(A.class);
add(B.class);
...
it seems that no problems occur when exporting to a jar.

Is there an easy explanation for this?

Ummmm.... I?m a bit confused: are the Predicate classes registered to your
ontology? NOTE that if you have
class A {
private B b;
...
public B getB() {
return b;
}
public void setB(B b) {
this.b = b;
}
...
}
and in your ontology you register A as
add(A.class)
B is automatically registered too.

Hi,
The SerializableOntology is used unless the normal ontology is able to
manage an object ?
If the class of a Predicate object that you insert in the
jade.util.leap.List is registered in the Ontology, the ontology manages it
and, since it is a Predicate (that cannot be used in an aggregate) ? it
fails.
If on the other hand such class is not registered in the ontology ? the
ontology does not manage it ? The SerializableOntology manages it and
things will work.

I understand from your comments that even with the SerializableOntology I
should still be getting the "No term object in aggregate" exception.

Can you also details more the environment you are using when things
?magically? works? I mean: are you working inside an IDE such as Eclipse?
Yes, I am using Eclipse Juno, with JDK 1.7.
If so can you tell me the IDE and how the relevant classes are spread across projects?
I am using a single java project, and add to the java build path jade.jar,
commons-codec-1.3.jar, among other jar files.
Another question: are the Predicate classes (I mean the classes of the
objects that you include in the jade.util.leap.List) explicitly registered
to the BeanOntology as
add(Pred1.class);
add(Pred2.class);
or through their package as
add("com.acme.rocket.ontology");
?
I am using the package version of add,
using add(this.getClass().getPackage().getName());
My BeanOntology is in the same package as the predicates I want to use.
In any case, I've just tried using the add(Pred1.class) version and the
results are the same.
Thanks.

I have an update on this.
Apparently it does not have anything to do with the underlying platform
(Windows/Ubunto). This was a misinterpretation of what was happening. Sorry
for that.
What I did find out is that my project works fine if I use my classes as such.
The problem arises when I export my classes to a jar file and then try to
use the jar in another Java project. That is when the "No term object in
aggregate" exception is thrown (as explained before).
Any hints?

Hi,

Hi,
This is really surprising.
- Are the code and the jade libraries exactly the same in the 2 cases (Ubuntu and Windows)?
Yes.
- Is your ontology extending the BeanOntology class or directly the base Ontology class?
Extending BeanOntology.
- Is the list a java.util.List or a jade.util.leap.List?
The list is a jade.util.leap.List.
- Is your ontology including the SerializableOntology among its base ontologies?
Yes, it is using SerializableOntology.SERIALIZABLE (because I also need to
use a HashMap in another Concept). This is how the ontology constructor
MyOntology() {
super(ONTOLOGY_NAME, new Ontology[]{BasicOntology.getInstance(),
SerializableOntology.getInstance()});
...
...
}
- Can you provide the piece of code that creates the content whose
encoding fails in Ubuntu and works in Windows?
Z z = new Z(); // this is a Predicate
z.setX(x); // this is a jade.util.leap.HashMap (that's why I am using serializable)
z.setY(y); // this is a jade.util.leap.List of Predicates
try {
myAgent.getContentManager().fillContent(response, z);
} catch (CodecException | OntologyException e) {
e.printStackTrace();
}
Now, let me remind you that this works fine under Windows (apparently not as expected).
Thank you for any hints,
Henrique

Hi,
http://sharon.cselt.it/pipermail/jade-develop/2013q3/019293.html
Now, this seems to be exactly what I am misusing: placing Predicates inside a List.
The thing is that I have only came across this problem when running my
system under Ubuntu Gnome.
When using Windows no exception is thrown, and predicates flow inside
lists without any problem.
Is there an explanation for this?
Thank you.

Hi,

As mentioned Predicates cannot be inserted into aggregates --> For things to work you must NOT register the predicate classes to your ontology. In this way they are treated as Serializable objects (and therefore as terms) and the ontology does not complain if you insert them into an aggregate.
Likely if you register classes one by one you don?t add predicate classes --> NO Error.
If you add the whole package, predicate classes get registered) --> Error.

Now, why don?t you have the error inside Eclipse. Likely because, being the predicate classes in a different project, the search on all classes in a given package does not find them --> Actually they are not registered.

Bye,

Giovanni
