response.setHeader中url怎么传递参数

response.setHeader("Refresh","3,url=/db_project/index/index.jsp?username=<%=name%>");
name是我从servlet获取到的参数，没有问题，但是这样写jsp报错
为什么jsp会报错

你把报的错误信息贴出来

在myeclipse中编译都不通过

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 45 in the jsp file: /jsp/register.jsp
String literal is not properly closed by a double-quote
42: <%
43: String name=(String) request.getAttribute("name");
44: System.out.println(name);
45: response.setHeader("Refresh","3,url=/db_project/index/index.jsp?username=<%=name%>");
46: %>
47:
48: /c:if

response.setHeader("Refresh","3;url=/db_project/index/index.jsp?username=<%=name%>");试下。
