SPARQ.exec() and FILTER regex(...)

1. Ex. Query:
SELECT ?s
WHERE {
?s rdf:type :City .
FILTER regex(?s, "Cannes")
}

2. result:
<sparql xmlns='http://www.w3.org/2005/sparql-results#'>
<head>
<variable name='s'/>
</head>
<results>
<result>
<binding 
name='s'><uri>http://www.example.org/travel.owl#City/Cannes</uri></binding>
</result>
</results>
</sparql>


3. But I don't have this result assigned to the Collection<City>. Collection is 
empty.

Collection<City> citySameName = Sparql.exec(model, City.class, queryStr);

(When I block a FILTER, I get the entire collection.)

Why?

Best regargs,
P.W.Więc

XMLLiteral datatype support in JenaBean for Bean2RDF

What steps will reproduce the problem?
1. Define a Bean with a property of type LocalizedString
2. When the model is used to generate RDF/XML A NullPointerException is 
encountered in JenaHelper.toLiteral(Model m, Object o).
3. This is due to the fact that the Object of Type LocalizedString is not 
handled in Writer. It is handled only in Rdf2Bean.

What is the expected output? What do you see instead?
The rdf shud contain the property with xml:lang attribute
<x:name xml:lang="en">test_en</x:name>

What version of the product are you using? On what operating system?
Jena 1.06 on Windows 7

Please provide any additional information below.
I have attached the changed file, please look out for the comment in the file
//Made changes by Chiths to handle xml:lang Literal

JenaHelper.java

Datatype Property: binding of BigDecimal to xsd:decimal is faulty

What steps will reproduce the problem?
1. create class that has BigDecimal datatype property 
2. write a concrete instance, is written as xsd:double instead of xsd:decimal 
3. reading the class leads to the return of a null value.

sample code:

controller:
    public void performTest()
    {

        RDF2Bean modelReader;
        Bean2RDF modelWriter;
        Test newTest = null;
        int idNumber = 0;

        OntModel m = ModelFactory.createOntologyModel();

        modelReader = new RDF2Bean(m);
        modelWriter = new Bean2RDF(m);
        modelReader.bind(Test.class);
        idNumber = getRandom();

        newTest = new Test();
        newTest.setId(idNumber);
        newTest.setValue(new BigDecimal(666.0));

        modelWriter.save(newTest);

        Test returnTest = (Test) modelReader.load(Test.class,idNumber);

        System.out.println(returnTest.getValue());
    }

testclass:

import thewebsemantic.Id;
import thewebsemantic.Namespace;
import java.math.*;

public class Test {

    @Id
    private int id;

    private BigDecimal value;

    public int getId() { return this.id; }

    public BigDecimal getValue() { return this.value;}

    public void setValue(BigDecimal pHasNativeValue) { this.value = pHasNativeValue;}

    public void setId(int pId) {this.id = pId;}
}

What is the expected output? What do you see instead?
The expected output is the stored BigDecimal value. It should be stored as 
xsd:decimal according to jena mapping.
Instead, it is stored as xsd:double value by jenabeans. therefore a 
java.lang.Double class is returned which leads to a "null" value when querying 
for the datatype property.

What version of the product are you using? On what operating system?
Version: jenabean-1.0.6.jar,
OS: Eclipse platform

Please provide any additional information below.
the property value is stored as xsd:double while xsd:decimal would be required.

Clean remove for Bean with array

Problem:
When creating a bean with Array-like attribute, it is correctly saved to the 
model but cannot be properly removed. The statement containing the array is not 
eliminated and the model is let with:
<rdf:Description rdf:nodeID="A0">
    <rdf:type rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq"/>
  </rdf:Description>


What steps will reproduce the problem?
1. Create a simple bean like the following:
public class Relation {
    Entity[] members;

    public Entity[] getMembers() {
        return members;
    }

    public void setMembers(Entity[] members) {
        this.members = members;
    }
}
Where Entity is a random JenaBean.

2. Create entities and link them with relation

Model m = ModelFactory.createDefaultModel();
MyBean2RDF writer = new MyBean2RDF(m);

Entity e1 = Entity();
Entity e2 = Entity();

Relation r1 = Relation();
r1.setMembers(new Entity[]{e1,e2});

// save
writer.save(e1);
writer.save(e2);
writer.save(r1);
m.write(System.out);

// delete
writer.delete(e1);
writer.delete(e2);
writer.delete(r1);
m.write(System.out);

3. look at the output...

What is the expected output? What do you see instead?
Expected output:
<rdf:RDF
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:owl="http://www.w3.org/2002/07/owl#"
    xmlns:j.0="http://thewebsemantic.com/"
    xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" >
... 
</rdf:RDF>

What i got instead:
<rdf:RDF
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:owl="http://www.w3.org/2002/07/owl#"

OWL or RDF

Hello,

First, I'd like to thank you for a brilliant idea of JenaBean. This is what
we are exactly looking for. Here are I one question:

Is there any particular reason classes are defined in OWL (as instances of
owl:Class) and properties in pure RDFS (as instances of rdf:Property, not
as owl:ObjectProperty or owl:DatatypeProperty) ?


> What is the expected output? What do you see instead?

For example you may see the following N3 output of Sensor2 class and
timestamp property.

<http://unimore.ecosystem.zombie.sensor/Sensor2>
      a       owl:Class ;
      <http://thewebsemantic.com/javaclass>
              "unimore.ecosystem.zombie.sensor.Sensor2" .

<http://ecosystem.it#timeStamp>
      a       <http://www.w3.org/1999/02/22-rdf-syntax-ns#Property> .

> What version of the product are you using? On what operating system?

The fresh checkout from SVN repository.

Best,

Maciej

Bean2RDF slow when serializing large arrays

What steps will reproduce the problem?
1. Use deep copy on object with very large array
2.
3.

What is the expected output? What do you see instead?
Expected decent serialization time.  Instead, getting exponential growth on 
runtime based on array size.

What version of the product are you using? On what operating system?
Version 1.0.7, Linux Ubuntu 11.10

Please provide any additional information below.

In Bean2RDF.java, I changed the class of the 'cycle' field to a HashSet<Object> 
instead of an ArrayList.  Since the major operation of this field is to 
identify the presence of an object already serialized,  the 'contains' and 
'add' methods are the only methods used.  For this, I think a HashSet would be 
a much better data structure to use as we can get constant time performance on 
both these operations.

ValuesContext#getGenericType(ParameterizedType) not working in all cases

Hi, I got a 
java.lang.ClassCastException: 
sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to 
java.lang.Class
    at thewebsemantic.ValuesContext.getGenericType(ValuesContext.java:69)

When using field that's type is a List of generic types. I changed the code to 
the following to make it work:

    public Class<?> getGenericType(final ParameterizedType type) {
        // unfortunately we don't have the TypeVariable information from the reference to this type,
        // so some TypeVariable->Type mappings are missing
        final Map<TypeVariable<?>, Type> typeVariableMap = new HashMap<TypeVariable<?>, Type>();
        final Type actualType = type.getActualTypeArguments()[0];
        return getClassForType(actualType, typeVariableMap);
    }

    public Class<?> getGenericType(final ParameterizedType type, final HashMap<TypeVariable<?>, Type> typeVariableMap) {
        final Type actualType = type.getActualTypeArguments()[0];
        return getClassForType(actualType, typeVariableMap);
    }

    private Class<?> getClassForType(final Type type, final Map<TypeVariable<?>, Type> typeVariableMap) {
        if (type == null) {
            return NullType.class;
        }
        if(type instanceof Class) {
            return (Class<?>)type;
        }
        if(type instanceof ParameterizedType) {
            final Type rawType = ((ParameterizedType) type).getRawType();
            return getClassForType(rawType, typeVariableMap);
        }
        if(type instanceof GenericArrayType) {
            final Type genericType = ((GenericArrayType) type).getGenericComponentType();
            // find class object of type the array is of
            final Class<?> arrayClass = getClassForType(genericType, typeVariableMap);
            // didn't find another way to get Class for array of type arrayClass
            return Array.newInstance(arrayClass, 0).getClass();
        }
        if(type instanceof TypeVariable<?>) {
            final Type actualType = typeVariableMap.get(type);
            // if we don't have mapping to actual type, we use most global class Object.class
            if(actualType == null) {
                return Object.class;
            }
            return getClassForType(actualType,typeVariableMap);
        }
        // don't know how to handle WildcardType and TypeVariable
        throw new IllegalArgumentException();
    }

    public Map<TypeVariable<?>, Type> getGenericTypeMap(final Type type) {
        final Map<TypeVariable<?>, Type> result = new HashMap<TypeVariable<?>, Type>();
        findTypeVariableMappingsRecursive(type, result);
        return result;
    }

    private void findTypeVariableMappingsRecursive(final Type type, final Map<TypeVariable<?>, Type> typeVariableMap) {
        // mappings for current type
        findTypeVariableMappings(type, typeVariableMap);
        // now mappings for supertypes and generic interfaces
        if(type instanceof Class<?>) {
            final Class<?> clazz = (Class<?>) type;
            final Type superType = clazz.getGenericSuperclass();
            if(superType != null) {
                findTypeVariableMappingsRecursive(superType,typeVariableMap);
            }
            final Type[] interfaceTypes = clazz.getGenericInterfaces();
            for (Type interfaceType : interfaceTypes) {
                findTypeVariableMappingsRecursive(interfaceType, typeVariableMap);
            }
        }
    }

    private void findTypeVariableMappings(final Type type,
            final Map<TypeVariable<?>, Type> map) {
        if (type instanceof ParameterizedType) {
            final ParameterizedType parameterizedType = (ParameterizedType) type;
            final GenericDeclaration genericDeclaration = (GenericDeclaration) parameterizedType.getRawType();
            final TypeVariable<?>[] typeVariables = genericDeclaration.getTypeParameters();
            final Type[] actualTypes = parameterizedType.getActualTypeArguments();
            for (int i = 0; i < actualTypes.length; ++i) {
                map.put(typeVariables[i], actualTypes[i]);
            }
        }
    }

I did also add support for generic arrays, although the framework do not seem 
to support arrays at the moment. Unfortunately the caller does not (and maybe 
cannot) provide information which TypeVariables are mapped to which actual 
types, or a ParameterizedType this information can be read from. I added 
methods for retrieving this information from a Type (see getGenericTypeMap).

Subclassing information

Hello,

Do you plan also to store also hierarchy of the classes, which are
instanciated in the Jena model.

What steps will reproduce the problem?
1. Compile the attached file (Test.java)
2. Observe the output

What is the expected output? 

I expected there will appear a statement:

:B rdfs:subClassOf :A .

What do you see instead?

All but not the statement.

NullPointerException upon Bean2RDF.saveDeep(myBean)

What steps will reproduce the problem?
1. trying to save my Jenabean class to RDF
2.
3.

What is the expected output? What do you see instead?
I expect it to save to Jena database, as my other Jenabean classes have

Please use labels and text to provide additional information.
I get this error.  It seems to be a problem with my Jenabean class.  Not
sure what I am doing wrong.  Can you figure what would cause this
NullPointerException?  My Jenabean class does have a lot of null values but
that shouldn't matter.  It has a proper
@Namespace("http://inqle.org/ns/v1/") declaration.  My getId() method
produces a string value and my Jenabean is of the expected class.  It
receives the @Id attribute through a superclass.  This has worked for me in
the past.  Thanks if anything springs to mind.

Current state of this library

Hi,
I would really like to try the library in my commercial product. But since the

NullPointerException hides true cause

What steps will reproduce the problem?

Follow the tutorial on the QuickStartReadingRDF wiki page
(http://code.google.com/p/jenabean/wiki/QuickStartReadingRDF) in a
haphazard manner, and leave the Bean in the default package.

What is the expected output? What do you see instead?

I get the following exception trace:

Exception in thread "main" java.lang.NullPointerException
    at thewebsemantic.TypeWrapper.<init>(TypeWrapper.java:46)
    at thewebsemantic.TypeWrapper.wrap(TypeWrapper.java:68)
    at thewebsemantic.RDF2Bean.newInstance(RDF2Bean.java:437)
    at thewebsemantic.RDF2Bean.applyProperties(RDF2Bean.java:425)
    at thewebsemantic.RDF2Bean.testCycle(RDF2Bean.java:394)

    at thewebsemantic.binding.Jenabean.load(Jenabean.java:101)
    at Test.main(Test.java:38)

The problem appears to be due to the use of Class.getPackage() in the
TypeWrapper constructor. getPackage() returns null when the class has no
package.

    private <T> TypeWrapper(Class<T> c) {
        ...
        Namespace nsa = c.getAnnotation(Namespace.class);
        NS = (nsa != null) ? nsa.value() : "http://"
                + c.getPackage().getName() + '/';

No doubt adding a package name to my bean will resolve the problem, but it
took me a while to understand the exact problem. Checking the return value
of getPackage and either throwing a more helpful exception, or working
round the lack of package would be helpful.

What version of the product are you using? On what operating system?

Jenabean 0.0.4 on Windows Vista.

How to generate java source class from rdf file?

Hi,

I have a rdf file which defines many classes with complex relations.
If uses jenabean, must I code each class in Java by hand? 
Or is there a tool that can automatically generate all java source classes? 

Allen

deep delete for jenabean

Bean2RDF.deleteDeep()

as a jenabean user, I should be able to call deleteDeep(bean) and have 
that bean and all related objects (in the bean object graph) deleted as 
well.

JenaBean should use the current thread's context ClassLoader

What steps will reproduce the problem?

In some runtime environments (eg. NetBeans Platform), JenaBean has a 
separate ClassLoader from the application classes. Therefore, 
Class.forName(..) is unable to locate those classes.

Spring has a similar problem with the NetBeans hierarchical ClassLoader.

What is the expected output? What do you see instead?

RDF2Bean.load(..) and loadDeep(..) throws ClassNotFoundException:

Make it possible to fetch raw Jena literals

What steps will reproduce the problem?
1. Create a Jenabean containing a com.hp.hpl.jena.rdf.model.Literal typed field
2. Annotate with @RdfProperty("http://www.w3.org/2000/01/rdf-schema#label")
3. RDF2Bean throws ClassCastException trying to cast String to Literal

What is the expected output? What do you see instead?
We would like to have the raw literal in order to be able to read additional 
properties like the 
language.

What version of the product are you using? On what operating system?
1.0.1, JVM 1.6.0

Please provide any additional information below.
Patch  available at 
http://bitbucket.org/fmancinelli/jenabean/changeset/858723a8d5ea/#chg-
src/main/java/thewebsemantic/JenaHelper.java

(A similar strategy should be implemented in Bean2RDF.toRDFNode() to handle raw 
literal 
serialization)
