尝试从 servlet 写入项目中的本地 xml 文件。当从另一个 java 类运行相同的代码时,不会发生错误,但是当代码从 servlet 运行时,我收到以下错误:
java.lang.ClassNotFoundException: org.jdom2.JDOMException
在 servletis 的 doGet 方法末尾粘贴到 servlet 的部分代码如下:
try {
SAXBuilder builder = new SAXBuilder();
File xmlFile = new File("C:\\eclipse\\workspace1\\BeamII\\WebContent\\Data.xml");
Document doc = (Document)builder.build(xmlFile);
Element Users = doc.getRootElement();
List<Element> myUsers = Users.getChildren();
Element beamUser = myUsers.get(0);
Element Data= beamUser.getChildren().get(2);
Element data1= new Element ("data1");
Data.addContent(data1);
XMLOutputter xmlOutput = new XMLOutputter();
xmlOutput.setFormat(Format.getPrettyFormat());
xmlOutput.output(doc, new FileWriter("C:\\eclipse\\workspace1\\BeamII\\WebContent\\Data.xml"));
// xmlOutput.output(doc, System.out);
System.out.println("done!");
} catch (IOException io) {
io.printStackTrace();
} catch (JDOMException e) {
e.printStackTrace();
}
我的进口如下:
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.jdom2.input.SAXBuilder;
import org.jdom2.output.Format;
import org.jdom2.output.XMLOutputter;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
谢谢您的帮助
