Hi Evan,
we are getting further in little steps, but first let me answer to your
points...
honestly for most things you mention i have only less idea. But let me try:
1. I do not build a channel if you mean that, i write to the
HttpServletResponse.getOutputStream, without dealing channel or not (?)
2. I did not use, i wrote directly to the outputstream, mentioned above.
But of course i tried now wrapping in a bufferedoutputstream -> same result
:-(.
3. I don't know. In deed i had tried the chunked transfer encoding, because
i read about it by a google search. I am rather sure, i did it correctly,
but
here the client (also browser on desktop machine) even didn't recognize
the chunked data format and wrote the complete chunked stream as is to the
file:
he also wrote the line seperators and the chunk size informations (what
did i wrong here?). I don't think that this would have solved the
connection reset anyway...
Apart from that i did not set any chunk or buffer sizes.
4. I tried downloading from the internet (underways via mobil net) and
through wifi at home.
5. ???
6. I updated my gwt project to 2.6.0, this did not solve anything too. And
in the library the HttpServletResponse i use is included.
7. I do not use any further library. I just use the rather plain servlet
api included with gwt 2.6.0.
But... let me come to the point!
My application runs within a tomcat where the server is normal http on port
8080. For public purposes i have an apache webserver in front which uses its
own ssl certificate and can only be accessed via https ! It forwards to the
local tomcat on http/8080. As said, this works fine on desktops and except
downloading also on mobile phones.
So, now guess. Yesterday at home it tried download via direct access to the
tomcat (none https) and it worked!
So, nice to know, but what could be the real problem and how to solve it? I
do not want to download via none secure connection.
Obviously this is a problem of the android download manager which deals the
download. In fact it seems that download via apache it does not recognize
the header information and therefore the download fails.
My ssl certificate is not registered of course it is self signed. Might
this be the problem? But what could i do. Is there a way to import my
certificate in android?
But it's hard to understand. Why behaves the download manager this way,
although the connection in browser is accepted by the user (if this is the
problem).
