HTTPClient hangs
Hi folks,
I am using multipart form post to upload a file.
The server side is production code that we are using
to upload files with other modules using multipart
form post. The failure/hang is happening only with the
HTTP Client code that I have pasted here. Also it is
worth noting that the server does a redirect after the
file is uploaded. But I don't even the response code
back since it just seems to stiing there at the
executemethod call. I was wondering if someone could
help me figure out what may be wrong here.
The executemethod never returns. From the trace it
looks like the the function HTTPParser.readRawLine
does not return. Here are the last few lines of the
trace and the source code that is being used. I am
running this under the following JVM version :
java version "1.4.1_06"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.4.1_06-b01)
Java HotSpot(TM) Client VM (build 1.4.1_06-b01, mixed
mode)

posting form information");
}
int responseCode =
httpClient.executeMethod(multipartPostMethod);
ArenaApp.getInstance().logMessage("File

}

Never mind my post. I just figured out I was using a
wrong version of a modified HTTPClient. Sorry I wasted
your time. Ignore my previous post.

Arun

Re: HTTPClient hangs

Hi Arun,
It seems that the server never responds to the request. My only guess
is that it's related to inconsistencies with how different servers
handle multi part posts. In particular, some servers seem to have
trouble with content-type and transfer encoding. Please try setting
both of these values to null for each of the string and file parts
being posted.
