servlet..
public void doget（httpservletrequest request, httpservletresponse response)
throws servletexception, ioexception {
response.setcontenttype（content_type);
string id= "1 ";

request.setattribute（id, "id ");
printwriter out = response.getwriter（);
out.println（ " <html> ");
out.println（ " <head> <title> newsservlet </title> </head> ");
out.println（ " <body bgcolor=\ "#ffffff\ "> ");
out.println（ " <input type= 'hidden ' name= 'id ' value= ' "+id+ " '> ");
out.println（ " <script> window.navigate（ 'maupdatehealthnews.jsp ') </script> ");
out.println（ " </body> ");
out.println（ " </html> ");
out.close（);
}
maupdatehealthnews.jsp

<html>
<body>
<%
string id=（string)request.getattribute（ "id ");
out.print（id);
%>
</body>
</html>

为什么得不到servlet的id 值啊

out.println（ " </body> ");
out.println（ " </html> ");
out.close（);
}

requestdispatcher view=request.getrequestdispatch（ " 'maupdatehealthnews.jsp ");
view.forward（request,response);//把请求响应对象带入到jsp中

这样就行了，不要用servlet写html。

out.println（ " <script> window.navigate（ 'maupdatehealthnews.jsp ') </script> ");

这句不对，应类似下面的语句跳转：
requestdispatcher rd = this.getservletcontext（).getrequestdispatcher（ "/csvmgmt/csvup.jsp?selected= " + result.substring（0, result.indexof（ "! ")) + "&pageid=1&result= " + result.substring（result.indexof（ "! ") + 1));
rd.forward（request, response);
