Juan Pablo Santos RodrÃguez commented on JSPWIKI-924:
-----------------------------------------------------
Hi Steven,
I cannot look at the code until later today, but just in case, on your
jspwiki.properties file, would you mind changing the attachment provider back
to {{jspwiki.attachmentProvider=BasicAttachmentProvider}} and set
{{jspwiki.usePageCache=false}} ? To rule out a possible cache problem.
thanks in advance,
juan pablo

> Key: JSPWIKI-924
> URL: https://issues.apache.org/jira/browse/JSPWIKI-924
> Project: JSPWiki
> Issue Type: Bug
> Components: Core & storage
> Affects Versions: 2.10.1
> Environment: CentOS 6.5 OS, Tomcat 7.0.42, 32-byte single line plain
> text attachment test file.
> Reporter: Steven Walsh
> Priority: Minor
> Attachments: jspwiki-EditRenameAttach-extract1.txt,
> jspwiki.policy-extract
>
>
> I'm trying to implement JSPWiki in a JAAS authentication
> SSO environment. I have installed JSPWiki and made some
> minor adjustments to the jspwiki.policy to account for
> different user role names, and everything seems to be
> working OK, except for one thing. None of the users
> (including the administrator) can add attachments to
> any of the pages. If I run the wiki standalone, (outside
> JAAS), attachments work fine.
> I'm using JSPWiki 2.10.1 with Tomcat 7.0.42 on a CentOS
> 6.5 server. My attachment test file is a one-line 32 byte text file.
> I have three basic user roles, all require JAAS authorization
> to access the wiki. User roles are admin, approved (read
> and write for most pages), and unapproved (read only).
> I'm fairly confident that the authentication methods are
> working properly as all page permissions are working as
> expected for each user type.
> But when any admin or approved user tries to add an
> attachment to any page, they get redirected to an Error.jsp
> page showing a java.lang.Exception. To try and track down
> the error source, I rewrote the AttachmentServlet class
> and added a number of additional debug messages.
> Based on what I'm seeing, it appears to me that the error
> is caused by the upload.parseRequest ( req ) returning
> an empty List<FileItem> fileItems in the upload method.
> I added a debug line to verify the contents of the request
> and it is properly populated entering the upload method,
> but it is consumed @ req.getParameter( "progressid" ).
> I commented out the use of the progress bar and found
> the request consumption moves to the context creation
> @ m_engine.createContext( req, WikiContext.ATTACH );
> Once it is consumed there, there is nothing left for the
> upload.parseRequest (req ) to read.
> I realize that I consumed the request by reading it for the
> debug message, but I only used it once per test run to
> determine where it was consumed. In the following log
> extract, that was at time 2015-11-25 14:05:41.892,
> which was after the createContext and before the
> upload.parseRequest.
> I'm inexperienced with the doFilter mechanism, and I see
> that it is part of the exception dump, and I don't know if
> that is working or not, but since upload.parseRequest ( req )
> is returning an empty fileItems list, I suspect there is
> something going on there. But I'm in over my head here.
> This is the log extract, starting right after the container JAAS
> has authorized the user.
