     WriteXML t = new WriteXML(); 
     t.m(); 
    } 

    private void m() { 

     XMLOutputFactory outputFactory = XMLOutputFactory.newInstance(); 

     try { 
     // Create the XMLStreamWriter object 
      // this is where it should create my file for xml 

      FileWriter fileWriter = new FileWriter("products.xml"); 
      XMLStreamWriter writer = outputFactory.createXMLStreamWriter(fileWriter); 

      //Here is the actual xml data   
      writer.writeStartDocument("1.0") 
      writer.writeComment("Product data");

      writer.writeStartElement("Product"); 
      writer.writeAttribute("Code", "Java"); 

      writer.writeStartElement("Description"); 
      writer.writeCharacters("Java SE 6.0"); 
      writer.writeEndElement(); 
      // for the Product element

該文件可能是在您不希望的目錄中創建的，例如the current working directory。嘗試指定絕對路徑。

Windows示例：

C:\Users\Walter\Desktop\products.xml
