I have made a JSP from where it's possible to upload files to the server. Once
the file is uploaded it is base64 encoded and the resulting string is inserted
in a textarea in the JSP. The page is then submited to the server.
My problem is that when I try to get the content of the field using
request.getParameter("base64file") I get the following error:
| java.lang.NullPointerException
| org.apache.catalina.connector.Request.parseParameters(Request.java:2340)
|
org.apache.catalina.connector.Request.getParameterNames(Request.java:1038)

| javax.servlet.http.HttpServlet.service(HttpServlet.java:810)

org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)

I only get the problem if I upload a large file (2mb+). I think that it has
something to do with size of the request, as it now contains the base64 encoded
file. Does anyone know what to do?
