download files from server

[MoreFeo]

Hi, I'm trying to follow thread thread695-824677 instructions, and it seems to work ok, except that the file created is 20 kB bigger than the original, and that files that are not plain text (like .doc or .zip) can't be opened.

Does anyone know what can cause this?

Thanks

Sorry, it's not 20kB, it's 20 bytes that it adds, I think at the begining of the file.

Here is the code I've tried:

<netui-data:getData resultId="path" value="{pageFlow.filePath}" />
<netui-data:getData resultId="name" value="{pageFlow.fileName}" />
<%
    String path = (String)pageContext.getAttribute("path");
    String name = (String)pageContext.getAttribute("name");
    
    response.setContentType("application/octet-stream");
    response.setHeader("Content-disposition", "attachment;filename="+name);
    
    File myFile = new File(path);
    OutputStream o = response.getOutputStream();
    
    FileInputStream fis = new FileInputStream(myFile);
    int i = fis.available();
    System.out.println("fis.available: " + i);
    int iRead;
    int iLength = 0;
    while ((iRead=fis.read())!=-1)
    {
        o.write(iRead);
        iLength++;
    }
    System.out.println("iLength: " + iLength);
    fis.close();
    o.flush();
    o.close();
%>

When I execute this, both fis.available and iLength give the current size of the file, but the file created is 20 bytes bigger and is corrupt.

If I try this with a plain text file, I can see that it adds 10 blank lines at the begining of the file.

Does anyone know how to fix this?

Thanks.

Well, I got it.

I was doing it in a JSP page, but it must be done from a servlet, because JSPs write more code than you want (each <%@ import inserts a blank line).

It seems that you use weblogic server
