大家早上好。

OWLOntologyManager manager OWLManager.createOWLOntologyManager = ();

我的服务：

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/semantichelper")
public class WS_SemanticMDX {
    @GET
    @Produces("application/xml")
    public String convertCtoF() {
        AssistenteSemantico moduloSemantico = new AssistenteSemantico();
        moduloSemantico.loadOWLOntology();

    return "";
    }
}

加载本体的方法：

public class AssistenteSemantico {
public static final IRI iri = IRI.create(
        "myIRI/NovaOntologiaDeFeriados.owl");

public OWLOntology loadOwlOntology(){
    OWLOntology owlOntologyRedirect = null;
    OWLOntologyManager manager = OWLManager.createOWLOntologyManager(); 

    manager.addIRIMapper(new SimpleIRIMapper(
            iri,
            IRI.create(new File(myPath/OntologiaDeFeriados-v4.owl"))));
    try {
        owlOntologyRedirect = manager.loadOntology(iri);
    } catch (OWLOntologyCreationException e) {
        e.printStackTrace();
    }

    return owlOntologyRedirect;
}

Answer 1

您的pom文件看起来是正确的，但是这个错误似乎表明您的web应用程序中没有正确地包含OWLAPI JAR。检查WEB-INF/lib的内容，owlapi-distributionjar应该在那里。

编辑：新的错误不会在OWLAPI3中发生--它引用的代码只有在OWLAPI4中才可用。我相信您现在的类路径中有多个版本。
