java - Accessing local files on Tomcat -

-

i'm using apache tomcat 7 , have servlet lists files in directory , allows users download files clicking on link.

here problem:

the files accessing in servlet not in project directory itself. in directory outside of tomcat directory itself

i.e.

project in /opt/apache-tomcat-7.0.53 files in /files/

when use anchor tag, can't reference using href="" because assumes directory within webcontent folder of project.

i tried doing href="file:///files/<file name> not click on link download file must wrong.

anyone know how work around this?

edit: should point out isn't running on local machine. on server.

you're better off looking @ tomcat aliases. let mount external directories in web app's context, , have tomcat serve file directly.

addenda:

the part of url before : called "scheme". examples include "http", "https", "ftp", "file".

the scheme tells browser "what do" rest of url, different schemes can have different formats after :.

so, url starting file:// use "file" scheme. file scheme tells browser try , open filename specified rest of url. filename local filename. local browser. not server.

you never use file:// type of url on server based application, on client side application.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
