My colleague is trying to make our application run on WebSphere (WAS 5.0), however we
are encountering an error submitting multipart forms. (Stacktrace pasted below)
(Needless to say it all works sweet on TomCat...)
Ive not had time to experiment with it myself, but it looks like WAS is barfing on the
org.apache.struts.upload.MultipartRequestWrapper object that struts wraps multipart
requests in so one can get at the parameters. This implements HttpServletRequest but
doesnt extend javax.servlet.http.HttpServletRequestWrapper in order to maintain
compatibility with Servlet2.2
Is it a requirement in WAS or the Servlet specs that all HttpServletRequest
implementations extend this?
(And why would it cause a problem? I thought the struts wrapper is ditched before
forwarding anyway?)
