Question

可能重复：
org.xml.sax.SAXParseException: Content is not allowed in prolog

我想在Jena模型中导入一个skos（rdf / xml）同义词库。 skos同义词库可在http://www.culturaitalia.it/pico/thesaurus/4.2/thesaurus_4.2.0.skos.xml中找到。我将其复制到本地文件（在picoFileName中），我使用此代码将其导入模型中：

    ...
    pico = ModelFactory.createDefaultModel();
    InputStream in = FileManager.get().open(picoFileName);
    if (in == null) {
        throw new IllegalArgumentException( "File: " + picoFileName + " not found");
    }
    pico.read(new InputStreamReader(in), "");
    ...

我收到此错误：

skos同义词库在w3c rdf / xml验证程序和skos验证程序中验证。有什么问题？

Answer 1

“picoFileName”究竟是什么？如果我在下载的内容上调用解析器，则适用于我。这是哪个版本的Jena？

Answer 2

抱歉，输入文件中出现了问题。我将文件内容复制到另一个文件中并且可以正常工作。

我正在使用Jena导入skos词库，但它不起作用
