java - 当我在耶拿使用类模型在 Web 服务中加载 RDF 文件时出错

标签 java web-services rdf jena invocationtargetexception

我有一个问题:

我想在我的 WebService 中加载 RDF 文件。

我写了这段代码:

@WebService(serviceName = "Prova_WS")
@Stateless()
public class Prova_WS{

    /**
     * Web service operation
     * @param f
     * @param label
     * @return 
     */
    @WebMethod(operationName = "operation")
    public String operation(@WebParam(name = "f") String f) {
        Model model = ModelFactory.createDefaultModel();
        InputStream in = FileManager.get().open( f );

        // read the RDF/XML file
        model.read(in, "");
        ResIterator sublist = model.listSubjects();
        Resource sub = null;
        while (sublist.hasNext()){
           sub = sublist.next();
           break;
        }

        return sub.toString();
    }
}

我已经完成了“清理和构建”、“部署”和“测试 WebService”操作，但是当我将此值插入到操作中时出现此错误:“C:/prova.rdf”(没有“”)。

为什么？我知道“C:/prova.rdf”不是空的。我错了什么？

最佳答案

正在执行

Model model = ModelFactory.createDefaultModel();

并给予:

java.lang.ClassNotFoundException: org.apache.xerces.util.XMLChar

这表明 Xerces jar(xercesImpl - 也需要 xml-api)不在运行时类路径上。

最好使用“file:C:/prova.rdf”，但这不是这里的问题 - 现在还不是问题。
