[Springframework-developer] (MultipartHttpServletRequest) request ClassCastException

[Sebastian S. <seb...@op...>]

Hello,

inside a simple Spring-Controller i try this:

public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
...
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)
request;
...

Buy at (MultipartHttpServletRequest) request i get a ClassCastException,
why?
The MultipartResolver is loaded correctly. For this i use the following line
in my application context XML:

  <bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

Lob Handler and so on is also defined in the XML. I looked at the imagedb
example but can't find the problem in my code.

Regards,
Sebastian
