解决方案
解决方案二：
R是用户应用程序和内部组件写的消息，是属于正常消息，不用管
解决方案三：
java.lang.NullPointerException是比较常见的一种错误，空指针异常，即下面这Oracle的APIatoracle.jdbc.driver.T4C8Oall.getNumRows(T4C8Oall.java:870)获取结果集时报错。com.ibm._jsp._selectPRTDesc._jspService(_selectPRTDesc.java:254)你可以看下这人Jsp的有用到数据库查询结果的哪一行检查一下，Debug一下是什么原因造成的。这种报错对系统一般都是有影响的。
