JSP image relative path problem

what is your current out.write() statement

I would use something like

out.write("<img src=\"../relative/path/to/img.jpg\">");

CJ

Here is what the out.write looks like

FileInputStream in = new FileInputStream('../path/to/afile.html');
while((lenght  = in.read(buffer)) != -1) {
   String s = new String(buffer,0,lenght);
   out.write(s);
}

I have to do it this way because, my future code will be modifying the file data after reading it in.

the 'afile.html' has <img src="someimg.jpg"> in it. The src is relative to 'path/to/' where the html file is located. But the jsp making the call to out.write is in some other location and hence the browser is unable to render the images.

-

  //to include the header page in my app we use
 <%
    ServletContext servletContext = getServletContext();
    RequestDispatcher requestDispatcher = servletContext.getRequestDispatcher("/folderinROOTdir/fileName.html");
    requestDispatcher.include(request,response);

%>

It would help if I knew a way to transfer the data (html file read in and modified) from one JSP to another in a chaining fashion. In that case I can have JSP in the same location as the HTML and it would just output the data it gets from another JSP. The browser would take location relative to the JSP in the same location as the HTML and things would work out just fine.

do a forward.
    RequestDispatcher requestDispatcher = getServletContext().getRequestDispatcher("/fileName.jsp");
    requestDispatcher.forward(request,response);

now that jsp can forward to another too.

if file.html has the img src and a jsp/servlet is reading it in from a completely different path than I would suggest changing your img src to full path http://yousite.com/imgs/img.jpg

CJ

I cannot change the image src as the HTML along with the images are uploaded by the user (in a zip file which I unzip). I don't want to put the HTML parsing and processing code in a JSP that gets duplicated in each of the directory containing the HTML.

I figure, if I could some how process the HTML and the send the processed HTML to a simple JSP whose job is to just output the processed HTML, then it might solve my problem.  I was thinking in the link of chaining, using requestDispatcher.forward(req,res).

But,

1. I am not sure how to pass large file from one JSP to another (can I use setAttribute() and getAttribute()? Will it be too large to put the entire HTML file data in them)

2. If there is a better solution, as the only purpose the second JSP is for setting the browser's relative path to the same place where the HTML is.

>img src to full path http://yousite.com/imgs/img.jpg

expanding on that suggestion -

put all your image in a folder under ROOT/images/
as ROOT/images/a.gif
    ROOT/images/b.gif etc.

In your html whenever yourefer an image call it as

<img src="http://www.ursite.com/images/a.gif">

I got it to working with sending the enitre HTML(after processing) in BufferedInputStream format using setAttribute and getAttribute and sendRedirect to the second JSP which just outputs the BufferedInputStream. But since the second JSP is located in the same path as the HTML page, the image links work.

CJ, I think you should get the points for all the trouble and help.
