Fellow Magnolia Users,
Has anyone had any success using the Jakarta Commons FileUpload library with
Magnolia. I am using Magnolia 2.1 with the standard version of Tomcat that
came with it. I can get a file to successfully upload when I put my
uploadForm.jsp and upload.jsp in the ROOT webapps folder, but when I put it
anywhere inside the magnolia author area the files in the multipart request
are not found when it has been parsed. It almost seem like it is getting a
different type of request alltogether when displaying magnolia pages than it
is when the JSP is running as a basic tomcat one.
What I am trying to do is add a file upload tab to admincentral in order to
give my authors a place to upload pdfs, docs, ppts, etc to a centralized
place. Basically, so that they can change their files in one place and have
those changes reflected in all the pages that link to these documents. I
have modified the adminCentral menu to incorporate the button and it
basically just sticks a JSP of my choosing in that right iframe.
Here is uploadForm.jsp:
<jsp:root version="1.2" xmlns:jsp = "http://java.sun.com/JSP/Page";>
<jsp:directive.page contentType="text/html; charset=UTF-8" />
<![CDATA[<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

}

</jsp:root>
Here is the output when I view the JSP in
%tomcat_dir%/webapps/ROOT/fileupload/
request = class org.apache.coyote.tomcat5.CoyoteRequestFacade
request has multipart = true
found a field: meh
found a file: ATM_POS_Map.jpg
done.
As you can see it parses the request fine and finds the file. It gets it and
everything is absolutely lovey dovey.
Here is the output when I view the JSP in
%tomcat_dir%/webapps/author/admintemplates/fileupload/
(note: I have a virtualuri mapper pointing
from /.magnolia/fileupload/uploadForm.html
to /admintemplates/fileupload/uploadForm.jsp
and from /.magnolia/fileupload/uploadForm.html
to /admintemplates/fileupload/upload.jsp)
request = class org.apache.catalina.core.ApplicationHttpRequest
pageContext.request = class
org.apache.catalina.core.ApplicationHttpRequest
request has multipart = true
no request info found!
done.
No such luck here.
Can anyone enlighten me as to why the class types for the two HttpRequests are
different and if there is any way to get hold of the original request? I
profusely apologize for the longwinded email. Thanks in advance to any help
you guys can offer. If you don't have a copy of the Jarkarta Commons
FileUpload library and would like to take a crack at this, it can be obtained
here: http://jakarta.apache.org/commons/fileupload/

It looks like when dispatched the request is cleaned of any additional parameters. Probably you
should try to debug and see what is happening when the request dispatched.
If you let me know what else you have done maybe I can try to find out too ;-).
