我在servlet是这么写的
response.setContentType("text/html;charset=gbk");
PrintWriter out = response.getWriter();
request.setCharacterEncoding("gbk");
String userName=request.getParameter("userName");
String password=request.getParameter("password");
String realName=request.getParameter("realName");
String sex=request.getParameter("sex");
UserBo ub=new UserBo();
int num=ub.createData(userName, password, realName, sex);
if(num>0){
out.print("<script > alert('注册成功，请登录！')</script>");
out.close();
response.sendRedirect("index.jsp");
}else{
out.print("<script > alert('注册失败，请重新注册！')</script>");
out.close();
response.sendRedirect("register.jsp");
}
但最后跳转不了，用转发也不行，在线等待！！！
