I am trying to execute following code.
import java.io.File;
import org.semanticweb.owlapi.apibinding.OWLManager;
import org.semanticweb.owlapi.model.AddAxiom;
import org.semanticweb.owlapi.model.IRI;
import org.semanticweb.owlapi.model.OWLAxiom;
import org.semanticweb.owlapi.model.OWLClass;
import org.semanticweb.owlapi.model.OWLDataFactory;
import org.semanticweb.owlapi.model.OWLOntology;
import org.semanticweb.owlapi.model.OWLOntologyCreationException;
import org.semanticweb.owlapi.model.OWLOntologyManager;
public class Snippet {
public static void main(String[] args) throws OWLOntologyCreationException {
File file = new File(
"file:///c/Users/DTN/Desktop/Final SubmissionFilteringMechanism_Ontology.owl");
OWLOntologyManager m = OWLManager.createOWLOntologyManager();
OWLDataFactory f = OWLManager.getOWLDataFactory();
OWLOntology o;
o = m.loadOntologyFromOntologyDocument(file);
OWLClass clsA = f.getOWLClass(IRI.create("urn:test#ClassA"));
OWLClass clsB = f.getOWLClass(IRI.create("urn:test#ClassB"));
OWLAxiom ax1 = f.getOWLSubClassOfAxiom(clsA, clsB);
AddAxiom addAxiom1 = new AddAxiom(o, ax1);
m.applyChange(addAxiom1);
for (OWLClass cls : o.getClassesInSignature()) {
System.out.println(cls.getIRI());
}
m.removeOntology(o);
}
}
It is generating following error.
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/inject/Provider at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at test.main(test.java:18) Caused by: java.lang.ClassNotFoundException: com.google.inject.Provider at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 25 more
Please some body help me out. thanks in advance.
what jars are you including in your classpath ?
It looks like you're missing some google guice dependencies. I suggest to use some dependency management tool such as maven or gradle
for instance, i solved that issue by using a maven dependency to
net.sourceforge.owlapi:owlapi-osgidistribution:4.0.2
on a maven project with your Snippet class as a main class.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>fake</groupId>
<artifactId>fake</artifactId>
<version>0.0.1-SNAPSHOT</version>
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>

</plugins>
</build>
<dependencies>
<dependency>
<groupId>net.sourceforge.owlapi</groupId>
<artifactId>owlapi-osgidistribution</artifactId>
<version>4.0.2</version>
</dependency>
</dependencies>
If you want to run it without using a dependency manager, make sure to have the following jars in your classpath (the following list was obtained with a maven dependency tree command)
