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＃34;清洁和构建＆＃34;，＆＃34;部署＆＃34;和＃34;测试WebService＆＃34;操作，但是当我将此值插入操作时出现此错误：＆＃34; C：/prova.rdf" （没有＆＃34;＆＃34;）。
