問題描述
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 = "<html><head></head><body>"+
"<a s HowTo</b></a>" +
"<h1>Show your support</h1>" +
"<p>It DOES cost a lot to produce this site - in ISP storage and transfer fees, " +
"in personal hardware and software costs to set up test environments, and above all," +
"the huge amounts of time it takes for one person to design and write the actual content.</p>" +
"<p>If you feel that effort has been useful to you, perhaps you will consider giving something back?</p>" +
"<p>Donate using PayPal? to real@rgagnon.com.</p>" +
"<p>Contributions via PayPal are accepted in any amount</p>" +
"<P><br/><table border='1'><tr><td>Java HowTo</td></tr><tr>" +
"<td style='background-color:red;'>Javascript HowTo</td></tr>" +
"<tr><td>Powerbuilder HowTo</td></tr></table></p>" +
"</body></html>";
worker.parseXHtml(pdfWriter, document, new StringReader(str));
document.close();
System.out.println("Done.");
}
catch (Exception e) {
e.printStackTrace();
}
}
}
這是我在網上找到的示例代碼.當我嘗試執行它時，我得到了這個錯誤:
This is a sample code that I found online.When I try executing it I get this error:
Exception in thread "main" java.lang.NoSuchMethodError: com.itextpdf.text.Paragraph.trim()Z
