Java-DOM-Parser：Transformer.transform上的异常

时间：2013-09-26 11:25:46

标签： java maven exception dom tomcat

我正试图从小时开始解决问题。我写了一个简单的应用程序来加载一个xml文件，修改它们并将更改写回来。它一直有效，直到我将项目转换为maven项目。我不确定这是不是问题。我无法理解异常

这是我的DOM-parser的代码部分：

import java.io.File;
import java.io.IOException;

import javafx.beans.property.BooleanProperty;
import javafx.beans.property.SimpleBooleanProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;

import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;
import org.w3c.dom.Node;
import **.***.Notification.*;

public class TomcatVM implements ViewModel{


Document tomcatDoc;
Node shutdownPortNode = null;
Node portNode = null;

private StringProperty port = new SimpleStringProperty();
private StringProperty shutdownPort = new SimpleStringProperty();
private BooleanProperty tomcatService = new SimpleBooleanProperty();
private String fullTomcatPropPath = new String();
private StringProperty path = new SimpleStringProperty();


public void init() {

    NotificationCenter.getDefaultNotificationCenter().addObserverForName(Notification.LOAD_NOTIFICATION.toString(), new NotificationObserver() {

        @Override
        public void receivedNotification(final String arg0, final Object... arg1) {
            // TODO Auto-generated method stub
            File tomcatXmlFile = new File(getFullTomcatPropPath());
            if(tomcatXmlFile != null){

                try{

                    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
                    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
                    System.out.println("got:   "+getFullTomcatPropPath());
                    System.out.println("path:   "+tomcatXmlFile.getPath());
                    tomcatDoc = dBuilder.parse(tomcatXmlFile);
                    tomcatDoc.getDocumentElement().normalize();

                    if(tomcatDoc != null){

                        shutdownPortNode = tomcatDoc.getElementsByTagName("Server").item(0).getAttributes().getNamedItem("port");
                        portNode = tomcatDoc.getElementsByTagName("Connector").item(0).getAttributes().getNamedItem("port");

                        //                  tomcatShutdownPortTextField.setText(shutdownPortNode.getTextContent());
                        setPort(portNode.getTextContent());
                        setShutdownPort(shutdownPortNode.getTextContent());

                    }

                }catch(Exception e){
                    e.printStackTrace();
                }
            }
        }
    });


    NotificationCenter.getDefaultNotificationCenter().addObserverForName(Notification.SAVE_NOTIFICATION.toString(), new NotificationObserver() {

        /*
         *  write changes from the interface to the doc file for
         *  the tomcat-xml file and overwrite the old tomcat-xml
         */

        @Override
        public void receivedNotification(final String arg0, final Object... arg1) {

            portNode.setTextContent(getPort().toString());
            shutdownPortNode.setTextContent(getShutdownPort().toString());

            TransformerFactory transformerFactory = TransformerFactory.newInstance();
            Transformer transformer;

            try {
                transformer = transformerFactory.newTransformer();
                DOMSource source = new DOMSource(tomcatDoc);
                StreamResult result = new StreamResult(new File(getFullTomcatPropPath()));
              enter code here // ******here is the exception: *******
                transformer.transform(source, result);
            } catch (TransformerConfigurationException e) {
                e.printStackTrace();
            } catch (TransformerException e) {
                e.printStackTrace();
            }
        }
    });


}



public String getFullTomcatPropPath() {
    return fullTomcatPropPath;
}

public void setFullTomcatPropPath(final String fullTomcatPropPath) {
    this.fullTomcatPropPath = fullTomcatPropPath;
    }

}

这就是我得到的例外情况：

我没有为dom-parser的pom.xml添加任何依赖项。 SAME CODE正在另一个项目中运行，唯一的区别是，我得到异常的项目是maven项目。如果我注释掉该行，我在另一个保存其他xml文件的类上得到了异常。所以我觉得tomcat不是问题吗？ 有人有想法吗？ ：/

提前致谢！

答案 0 :(得分：3)

在没有maven的独立项目中，您是否包含任何罐子/进口？如果相同的确切代码在那里工作，但不是在maven中它会让我相信你有一个依赖性错误。

尝试将此依赖项添加到pom.xml：xercesImpl.jar 

<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.11.0</version>
</dependency>
