尝试在XStream中解组时，我遇到异常。

实际上它一直工作到今天。突然之间，我开始收到这个错误，因为我添加了几个插件到mu = y Eclipse Kepler IDE。 在传递xml之前，我正在完成所有可能的先决条件。我的代码段在下面提到 - 

XStream xstream = new XStream(new DomDriver());

         xstream.alias("service", ServiceDetails.class);
         xstream.alias("allServices", ServiceDetailsList.class);

         xstream.addImplicitCollection(ServiceDetailsList.class, "list");

         // Serialize the XML to Java object

            try {
                logger.info( "XML Path : " + CommonConstants.FOLDER_PATH);
                File inputXMLFile = new File(CommonConstants.FOLDER_PATH+CommonConstants.INPUT_XML_NAME);

                if (inputXMLFile.exists()){
                    fis = new FileInputStream(inputXMLFile);

                    //De-serializing XML to Java object
                    ServiceDetailsList serviceList = new ServiceDetailsList();
                    try {
                        serviceList = (ServiceDetailsList)xstream.fromXML(fis);
                    }catch (CannotResolveClassException crce) {
                        // TODO Auto-generated catch block
                        logger.error(crce.getMessage());
                    }catch (ConversionException ce) {
                        // TODO Auto-generated catch block
                        logger.error(ce.getMessage());
                        logger.error(ce.getStackTrace());
                        logger.error(ce.getCause());
                    }

查看“ServiceDetails.xml”后。我注意到它不是有效的...没有＆lt; service＆gt;由第二个＆lt; name＆gt; ....包围的开始和结束标记。＆lt; sendMail＆gt;标签..所以，这是给出例外..首先检查它..纠正它后没有给出例外...使用以下xml而不是上面的
