Subject [jira] Commented: (HTTPCORE-241) "Socket Exception: Bad file number" when passing chunked entity back to response
Date Wed, 24 Nov 2010 01:04:18 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12935158#action_12935158

John B. Hansen commented on HTTPCORE-241:
-----------------------------------------

Hi Oleg,

  I took your advice and downloaded 4.1 on the desktop and worked on a fresh
build environment using J2SE 1.6.0.22. It has worked like you said.

   - The transfer encoding: chunked site worked fine
   - I was also able to make other proxy changes successfully avoiding the
   bad file number socket problems (below).

But, I still need to port 4.1 now to Android. I'm wondering if I still have
to do that because the only unresolved references
in my new code (relative to 40-beta2) are:

   - ImmutableHttpProcessor references (change back to BasicHttpProcessor?)
   - SyncBasicHttpParams references (change back to BasicHttpParams?)
   - HttpService constructor has a few more params?

I realize the 40-beta2 code is old but it is still installed on all the
ANdroid 2.2 phones. Wondering if you strongly
recommend the 4.1 porting? If you do, is that just a matter of importing the
4.1 JAR and establishing
a new namespace for it so it doesn't conflict with the HttpComponent code in
ANdroid 2.2
(I'm assuming that is possible and simple)?

Anyway, let me know what you think. I really appreciate all your help and I
can close my earlier bug if you like.

jh

P.S. Do you have any insight into the HttpComponents version that Google
will use on upcoming versions of Android?
I understand if you don't or cannot comment.

to proxy code.

gets a response

e.g. www.google.com

> Any ideas what could be wrong or how to debug? Any advice appreciated....Thanks!
> PS, if anyone can clarify the version of HttpComponents on Android 2.2 also, that would
be great. Thx.
