Multipart Request problem

[Gambito]

Hi

I'm having some problems with the MultipartRequest
class by Oreilly.

I'm trying this code:

try {
MultipartRequest multi = new MultipartRequest(request, "/var/tmp",
10*1024*1024); // 10MB
} catch (Exception e) { out.println(e.getMessage());
}

and getting this error:

description The server encountered an internal error () that prevented
it from fulfilling this request.

exception

org.apache.jasper.JasperException: javax/servlet/ServletRequest
at org.apache.jasper.servlet.JspServletWrapper.service(Unknown Source)

root cause

maybe i'm missing a configuration or it's a tomcat bug. I'm using Tomcat
4.1. It works fine on Tomcat 3.3. Any idea?
