您好我正在使用YaHPConverter将我的html文件转换为PDF文件。当我从Eclipse运行时，我得到一个PDF文件，但是当我从命令提示符运行我的java文件时，我得到一个异常。我已将jar文件放入以下路径。
/usr/local/jdk1.7.0_21/jre/lib/ext

public class App {
public static void main(String[] args) throws DocumentException, IOException {
Document document = new Document();
try {
String root = "/home/ubuntu/Desktop";
String input = "index.html"; // need to be charset utf-8
htmlToPdfFile(new File(root, input), new File(root, input + ".pdf"));
System.out.println("Done");
} catch (Exception e) {
System.out.println("Exception Generated======>>" + e);
}
document.close();
}
public static void htmlToPdfFile(File htmlIn, File pdfOut) throws Exception {
Scanner scanner = new Scanner(htmlIn).useDelimiter("\\Z");
String htmlContents = scanner.next();
CYaHPConverter converter = new CYaHPConverter();
FileOutputStream out = new FileOutputStream(pdfOut);
Map properties = new HashMap();
//ArrayList headerFooterList = new ArrayList();
ArrayList<String> headerFooterList = new ArrayList<String>();
//List<String> headerFooterList = new ArrayList<String>();
properties.put(IHtmlToPdfTransformer.PDF_RENDERER_CLASS, IHtmlToPdfTransformer.FLYINGSAUCER_PDF_RENDERER);
//properties.put(IHtmlToPdfTransformer.FOP_TTF_FONT_PATH, fontPath);
converter.convertToPdf(htmlContents, IHtmlToPdfTransformer.A4P, headerFooterList, "file:///temp/html/", out, properties);
out.flush();
out.close();
}
}
这是我的java文件，当我运行它时，我得到以下异常。
