修改密码
在用myeclipse6.5实现修改密码时，即使输入的密码跟数据库里的密码相同，它也显示错误，我在控制台输入密码，发现密码没错，是不是myeclipse6.5有问题？
以下是servlet部分的代码
package cn.com.jobedu.my_case;

if (method.equals("adminLogin")) {
adminLogin(request, response);

changeAdminPassword(request,response);
}
}

}
String oldAkey=request.getParameter("oldAkey");

System.out.println(oldAkey);
System.out.println(newAkey);
System.out.println(reNewAkey);
System.out.println(adminInfo.getAkey());
if(!adminInfo.getAkey().equals(oldAkey)){
request.setAttribute("message", "输入的原密码错误！");
request.getRequestDispatcher("/admin/changeAdminPassword.jsp").forward(request, response);
}else if(newAkey.equals(reNewAkey)){

try {

}
response.sendRedirect("/case/admin/admin.jsp");
}else{
request.setAttribute("message", "请输入相同的新密码！");
request.getRequestDispatcher("/admin/changeAdminPassword.jsp").forward(request, response);
}
}
}
servlet部分的代码并没有错误，麻烦各位大侠帮忙看看如何解决，谢谢
[解决办法]
是不是你输入密码的时候有空格呢，你去除空格在用新输入的密码和对象里面的密码做比较，试试
[解决办法]
有些猜测，不过需要验证，麻烦你在这些输出中，增加下面几句话，然后告诉我结果：
System.out.println(adminInfo.getAkey().equals(oldAkey));
System.out.println("[" + adminInfo.getAkey() + "]");
