一个xml不规范导致的错误

java源码

package jelly;

import java.io.FileWriter;
import java.io.Writer;

import org.apache.commons.jelly.JellyContext;
import org.apache.commons.jelly.XMLOutput;

public class JellyTest {
 public static void main(String args[]) throws Exception {
  Writer someWriter = new FileWriter("C:/workspace/jackMoTool/output1.xml");
  XMLOutput output = XMLOutput.createXMLOutput(someWriter);
  // now run a script using a URL
  JellyContext context = new JellyContext();
  context.runScript("output.xml", output);
 }
}

 

配置文件

//少了?  正确应该为 <?xml version="1.0"?>

<?xml version="1.0">
<j:jelly xmlns:j="jelly:core">
 Hello World!
</j:jelly>
