Your request wrappers store their own reference to a
HttpServletRequest in addition to the one stored by the
ServletRequestWrapper class.


My guess is that your issue will be solved if you either override
ServletRequestWrapper.setRequest() to update your request field,  or
use ServletRequestWrapper.getRequest() method to access the wrapped
object, instead of storing it by yourself.

Sounds like good advise.

You have to provide the actual source code.

There is an example in the examples webapp that performs forwarding to
a JSP and it works,

\webapps\examples\WEB-INF\classes\ServletToJsp.java

So the good news is that I got it to work by getting rid of any of the
methods that were overiding the implementation with a call to the child
request.  Here's the links to the code that does NOT work : (I haven't
checked in the working code yet):

RE: very strange. SOLVED

[Asensio, Rodrigo]

Hi all, FYI, 
There was a callback function that was trying to execute after the
window was closed. For that reason, the screen stays blank.

Regards.

Just a thought. This seems the typical situation in which the webapp
runs out of available db connections. Do you close all the connections
when you finish your operations?
