------解决思路----------------------
java.lang.NullPointerException
org.apache.jsp.index_jsp._jspService(index_jsp.java:287)
空指针，程序有逻辑错误，检查index.jsp吧。
------解决思路----------------------
如果使用的是eclipse ，可以在工作空间中找到编译的index_jsp.java 类，然后找到对应的错误行 287 ,对照index.jsp 就知道哪行有问题了。
路径类似 workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp...
