Andreas Antener commented on MAGNOLIA-2909:
-------------------------------------------
Thank you for the hint.
I had a short look into the code. Basically what you are doing is delegating
the action to struts for processing in a renderer, right?
In the meanwhile I tried to do something similar with a filter in the Magnolia
filter chain. My filter just delegates the request to the struts dispacher. It
works with post-requests if the filter is positioned after "multipartRequest".
Also it was necessary to check on loops because struts calls Magnolia sites as
result pages, which is why I'm not quite sure if this is the correct approach
to solve it..

> Key: MAGNOLIA-2909
> URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-2909
> Project: Magnolia
> Issue Type: Bug
> Affects Versions: 4.1.1
> Environment: struts 2.1.6, tomcat 6
> Reporter: Andreas Antener
> Assignee: Boris Kraft
> Attachments: stacktrace.txt, web.xml
>
>
> First, what are we trying to do:
> We have already existing applications that are using Struts and we would like
> to integrate them in Magnolia. The idea is to use these existing applications
> as paragraphs, which can be placed anywhere on the site.
> JSP templates came in handy to include pages that are using struts tags. We
> added the struts filter-dispacher and mapped him BEFORE magnolia (see
> attachement).
> From now on, struts tags get executed and they work as expected. However, the
> thing that does not work anymore are POST requests that are directed to
> Magnolia itself (meaning every Magnolia dialog / input etc.). Magnolia
> terminates parsing those request with the following exception:
> java.io.IOException: Corrupt form data: premature ending
>
> com.oreilly.servlet.multipart.MultipartParser.<init>(MultipartParser.java:205)
> com.oreilly.servlet.MultipartRequest.<init>(MultipartRequest.java:222)
>
> info.magnolia.cms.filters.CosMultipartRequestFilter.parseParameters(CosMultipartRequestFilter
> .... (see attachement for full stacktrace)
> I read that this could be an MultipartParser-library related incompatibility
> with Struts:

> Any suggestions?
