Re: accessing an image outside my webapp

[Mark Lowe]

Have an action that write the image to the response

response.setContentType("image/jpeg");
response.setHeader("Cache-Control", "no-cache");
OutputStream ou = response.getOutputStream();

String imageStr = "/path to image";
java.net.URI imgUri = new java.net.URI(imageStr);
File imageFile = new File(imgUri);
RandomAccessFile raf = new RandomAccessFile( imageFile, "r" );
FileInputStream imageFileStream = new FileInputStream(imageFile);
byte[] image = new byte[(int) imageFile.length()];
while ( (raf.read( image )) > 0 ){
                ou.write( image );
}
ou.flush();
ou.close();
return null;
//map the action

<action path="/image" type="com.sparrow.struts.ImageAction" />

//

call the action

<html:img page="/image.do" />

The client browser is making a request to a webserver using a  
"relative
address" I think it would be best to understand the difference  
between
"relative addressing" and "absolute addressing"

I don't think Tomcat does, but your local browser will.  You are  
sending
your browser a link that tells it to load a file on your file  
system.  It
will work fine if you are only running locally, but it won't work  
if you
try
to access that link from a browser on another machine unless that  
machine
also has the same file locally.

by jingo. it only works!!

just src rather than href

<html:img src="file:///test.jpg" />

I thought tomcat wouldn't have access to anything outside the  
webapp.

seems like an odd request... but here goes...

<html:img href="file://c:/photo directory/foo.gif"/>

html:img supports three attributes for specifyin the location of an
image
forward (referes to a global forward), page (relative to the  
current
web
context), and href (any valid URL).

I have a JSP where I would like to show an image located outside my
webapp
(e.g. in a c:\photo directory)  ...
How to do that with the <html:img> Struts tag ??

Thanks

Alain
