Question

JSP, how to get real path of any file?

Asked by: cassiej81

Hi,

My JSP page using a properties file call "config.properties" and i put it on WEB-INF.I used

getServletContext().getRealPath("/")+"/WEB-INF/config.properties" to get the path to it, but how can i get the path to it without declare a detail path like that.Does Jsp/servlet have any function which can scan for a file and give us a real path?

Thanks in advance!

Try

InputStream in = getClass().getResourceAsStream("/WEB-INF/config.properties");

and read it

 

by: cassiej81Posted on 2007-12-17 at 02:15:31ID: 20483803

Thanks CEHJ, but it said null :((

And what i need is a function(or anything like this) which can return a full path of this file
i.e: getFilePath("config.properties"); it's return "/root/somedir/config.propertoes"

 

by: CEHJPosted on 2007-12-17 at 02:18:35ID: 20483817

OK what happens when you call the code you had yourself?

 

by: CEHJPosted on 2007-12-17 at 02:19:29ID: 20483820

btw if you put your file in /WEB-INF/classes the code i posted should work

 

by: cassiej81Posted on 2007-12-17 at 02:26:02ID: 20483841

it's will return the real path of my file. I ask this question because i dont' want to change the code(to a new path) if i put the config.properties on another folder. Any solution?

 

by: CEHJPosted on 2007-12-17 at 02:32:59ID: 20483866

That can't be done - if you change the folder, you must change the code.

 

by: cassiej81Posted on 2007-12-17 at 02:52:09ID: 20483924

Are you sure?

I still think there are have a function which can recursive all the folder and return the path of file, googling for it now

 

by: CEHJPosted on 2007-12-17 at 02:56:50ID: 20483943

Well you could do that but it's messy. Why do you need to do this? Why not just put it in the same place each time?

 

by: cassiej81Posted on 2007-12-17 at 17:25:10ID: 20489440

Hi CEHJ,

but if i put it in WEB-INF/classes/ , there're have another way to get it without include web-inf (getClass().getResourceAsStream("/WEB-INF/config.properties");) ?

 

by: cassiej81Posted on 2007-12-17 at 17:26:21ID: 20489446

btw, i also got the null when i use your code

 

by: CEHJPosted on 2007-12-18 at 04:48:02ID: 20491530

If you put it in WEB-INF/classes you can get it with

InputStream in = getClass().getResourceAsStream("/config.properties");

                                              
1:

Select allOpen in new window

 

by: cassiej81Posted on 2007-12-19 at 18:15:48ID: 20504505

Yeah, thanks CEHJ, i got it
