[解决办法]
org.apache.jsp.WebContent.register_005fnew_005fuser_jsp._jspService(register_005fnew_005fuser_jsp.java:116)

去 tomcat/work
子目录下面找到这个register_005fnew_005fuser_jsp.java

看看第116行为何为null
[解决办法]
//注册成功即意味着登录成功，迁移到游戏选择画面
response.sendRedirect("entry.jsp");

out.write('\r');
out.write('\n');


红色部分有问题吧，你都跳转页面了还输出，试一下，是不是这里有问题？？？？
[解决办法]

探讨

把页面缓存改大些试试，应该是 sendRedirect 时响应已经被提交了（响应数据已经开始向客户端发送了）。

难道是有字段类型不匹配？
