Hi
I would like to implement an interface called FileRenamePolicy from the
oreilly package for uploading files, and I am creating a class which
does the implementation.
Here is the relevant code:
<%@ page session="true"%>
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%@ page import="java.net.*" %>
<%@ page import="java.text.*" %>
<%@ page import="java.util.*" %>
<%@ page import="com.oreilly.servlet.*" %>
<%@ page import="com.oreilly.servlet.multipart.*" %>
<%
abstract class reName implements FileRenamePolicy {
public File changename (File oldname) {
DefaultFileRenamePolicy dfrp = new DefaultFileRenamePolicy();
FileRenamePolicy frp = (FileRenamePolicy) dfrp;
File savename = frp.rename(oldname);
return savename;
}
}
%>
Apparently this class needed to be abstract for the jsp to compile.
Later on in the code, I would like to rename the file. First I create a
MultipartRequest object:
MultipartRequest mr = new
MultipartRequest(request,"/var/www/projects_data/");
Then I upload the file object:
File oldn = mr.getFile(mr.getParameter("audit_doc"));
And then I rename the file:
File newname = reName.changename(oldn);
But here is when I get the error:
"non-static method changename(java.io.File) cannot be referenced from a
static context"
What does this mean and what am I doing wrong?
After I rename the file, I would still like do download it (using the
new filename) to /var/www/projects_data/.
I think I have to use a method from the oreilly package named
FilePart.writeTo().
Would anyone be able to give me a hint on how to use this?
Any help, especially code examples, will be greatly appreciated.
Thanks
Hugo
