Hi All,

I'm using struts 1.2.9 and having requirement to upload  and process file,
obviously struts is handing multi-part request quite well however i'm
having some existing logic where we have created my own filter from where
all requests pass and i check authorization of user whether he is allowed
to send that request or not.

as struts handle multipart request in its own doFilter and beyond that code
and i need few of the request parameters in my own filter(before populating
form fields) i wrote some code and used Commons FileUpload jar (1.3.2) as
below in my filter.

        List<FileItem> items = new ServletFileUpload(new
DiskFileItemFactory()).parseRequest(request);

and i'm getting all the form fields and queryparams in the list, now the
problem is all those parameter are lost once i parsed request here, and
now  from request object and BeanUtil.populate can't set my FormBean. :( as
request object dont have it.

I saw code of commons fileupload but doesn't seems anything odd code which
is flushing all those parameters Can someone let me know if i'm missing
something here ?

Thanks,

Amey

Hello,

we are still using Struts 1.3.8 in a big project. And we are definetely 
not considering migrating to struts2. Because struts2 is a totally 
different framework - so no advantage to move to struts2 instead of 
another framework. So just pick the best solution for the future.

For us a long term maintanance is important. And a smooth migration. So 
we made the decision to migrate to a more service based architecture 
using JSON/REST with golang server and also some Spring middleware.

Just check which architecture is suiting you best and keep the Struts1 
running. Perhaps update to 1.3.10.

The EOL is not really an argument. Struts2 will have an EOL too.

Just my two cents

Norbert

(Struts 1 in production since 2003)

Hi,


please note that struts1 as been EOL'd long time ago. You should consider 
migrating to struts2.


The behavior you describe is correct: after your filter has consumed 
InputStream it is not available anymore for struts to process it. Just 
last week there was another thread on this list regarding this topic. 
Search the archives for "What is the best way to get all JSON params in 
custom Interceptor to log them all in a custom logger ?".

In your case you could use a workaround: put the paramters you need to 
check in URL instead of POST-body.


Regards,
Christoph
