Re: MultipartHttpServletRequest in a generator

By the way you asked, I guess in some sort of ridiculous attempt to get hold of some binary data that has been posted to a pipeline containing the generator :)

Hi,
How can I get hold of a MultipartHttpServletRequest in a generator?
If I do this...

HttpServletRequest request = infoProvider.getRequest();

I get the following error when the final line is executed...
java.lang.ClassCastException: $Proxy13

What's the secret?

final WebApplicationContext parentContext = WebAppContextUtils.getCurrentWebApplicationContext(); final ProcessInfoProvider infoProvider = (ProcessInfoProvider) parentContext.getBean(ProcessInfoProvider.ROLE); MultipartHttpServletRequest mpr = (MultipartHttpServletRequest) request; Eclipse debugger shows that request is an instance of MultipartHttpServletRequest.

The secret is how JVM proxies work with the fact that MultipartHttpServletRequest is a class not interface. Situations like this are little bit worrying me but anyway standard question: why do you want to cast to MultipartHttpServletRequest?
