使用itext的XML工作者

import java.io.FileOutputStream; import java.io.StringReader; import com.itextpdf.text.Document; import com.itextpdf.text.PageSize; import com.itextpdf.text.pdf.PdfWriter; import com.itextpdf.tool.xml.XMLWorkerHelper; public class HtmlToPDF2 { // itextpdf-5.4.1.jar http://sourceforge.net/projects/itext/files/iText/ // xmlworker-5.4.1.jar http://sourceforge.net/projects/xmlworker/files/ public static void main(String[] args ) { try { Document document = new Document(PageSize.LETTER); PdfWriter pdfWriter = PdfWriter.getInstance (document, new FileOutputStream("C:/Users/Jason/Desktop/testpdf.pdf")); document.open(); document.addAuthor("Real Gagnon"); document.addCreator("Real's HowTo"); document.addSubject("Thanks for your support"); document.addCreationDate(); document.addTitle("Please read this"); XMLWorkerHelper worker = XMLWorkerHelper.getInstance(); String str = ""+ "Real's HowTo" + "

这是我在网上找到的示例代码。当我尝试执行它时，我收到此错误：

 Exception in thread "main" java.lang.NoSuchMethodError: com.itextpdf.text.Paragraph.trim()Z at com.itextpdf.tool.xml.html.AbstractTagProcessor.currentContentToParagraph(AbstractTagProcessor.java:257) at com.itextpdf.tool.xml.html.Header.end(Header.java:93) at com.itextpdf.tool.xml.html.AbstractTagProcessor.endElement(AbstractTagProcessor.java:189) at com.itextpdf.tool.xml.pipeline.html.HtmlPipeline.close(HtmlPipeline.java:206) at com.itextpdf.tool.xml.XMLWorker.endElement(XMLWorker.java:141) at com.itextpdf.tool.xml.parser.XMLParser.endElement(XMLParser.java:395) at com.itextpdf.tool.xml.parser.state.ClosingTagState.process(ClosingTagState.java:70) at com.itextpdf.tool.xml.parser.XMLParser.parseWithReader(XMLParser.java:235) at com.itextpdf.tool.xml.parser.XMLParser.parse(XMLParser.java:213) at com.itextpdf.tool.xml.XMLWorkerHelper.parseXHtml(XMLWorkerHelper.java:175) at xml.HtmlToPDF2.main(HtmlToPDF2.java:41) 

我正在使用itextpdf-5.1.2.jar和xmlworker-5.4.3.jar.Please帮助
