我的jsp（Welcome.jsp）页面上有一个提交按钮，我将请求发送到myservlet（导入零件）。我在servlet中做了一些验证，验证失败后，我将用户重定向到错误.jsp页面，该页面给出了合适的消息。此错误.jsp还有一个关闭按钮，在我将响应转发到错误.jsp后不起作用。
如果我直接在浏览器中启动错误.jsp并尝试单击关闭按钮，它会起作用。
// Below is the piece of code written in my Servlet on doPost() method which perform some validation and upon failing the validation check redirects user to error.jsp page.
if(!UserDetails.checkValidUser(asession)) //a Validation method returning true or false
{
logger.info("User do not have necessary role");
request.setAttribute("error", EMSImportConstants.NO_PRIVILEGE_USER_ERR_MESSAGE);
RequestDispatcher rd = request.getRequestDispatcher("/Error.jsp");
rd.forward(request, response);
}
//Below is my error.jsp page code

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;

I click on close button but nothing happens.
在表单中，要提交详细信息，input类型应submit，但不应button。以这种方式更改代码。它应该:)工作
<form>
<td align="center"><input type="submit" value="Close" onclick="window.close();" /></td>
</form>
