连接SAP rfc一直报错如何解决？

问题如下：

代码：

复制代码

  static String ABAP_AS_POOLED = "ABAP_AS_WITH_POOL";
    private static Logger log;
    static {
        Properties connectProperties = new Properties();
        connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "IP");//IP
        connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, "00"); //编号
        connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "300");//客户端
        connectProperties.setProperty(DestinationDataProvider.JCO_USER, "test01"); //账号
        connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "mima"); //密码
        connectProperties.setProperty(DestinationDataProvider.JCO_LANG, "zh"); //语言
        connectProperties.setProperty(DestinationDataProvider.JCO_POOL_CAPACITY, "10"); //连接数
        connectProperties.setProperty(DestinationDataProvider.JCO_PEAK_LIMIT, "5"); //分页
        createDataFile(ABAP_AS_POOLED, "jcoDestination", connectProperties);
    }

原因：账号或者密码错了。

解决方案 ：我是用IDEA编译器，所以确保账号密码没问题后，重新编译一下再次运行项目就解决问题了。
