unable to find line starting with "HTTP"
Hello all.
>>From time to time I'm getting the following exception in my application:
org.apache.commons.httpclient.HttpRecoverableException:
org.apache.commons.httpclient.HttpRecoverableException: Error in parsing
the status line from the response: unable to find line starting with
"HTTP"
at
org.apache.commons.httpclient.HttpMethodBase.readResponse(HttpMethodBase.java:1965)
at
org.apache.commons.httpclient.HttpMethodBase.processRequest(HttpMethodBase.java:2659)
at
org.apache.commons.httpclient.HttpMethodBase.execute(HttpMethodBase.java:1093)
at
org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:675)
at
org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:558)
How can I manage it in my application? Can I find out what's going
wrong? Is it a server side issue?
Thank you very much.

Juan,
There's indeed no easy solution to this problem. There's a whole section
in our new exception handling guide on the issue of the transport safety
and HTTP methods' idempotency. The guide has not been published yet, as
it describes the new exception handling framework in the upcoming
release 3.0, which is incompatible with that of HttpClient 2.0. You will
have to deal with the 'raw' XHTML markup for now
http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/xdocs/exception-handling.xml?view=markup
Hope this helps a little. If you happen to have feedback or comments on
content of the exception handling guide, it will be highly appreciated

Re: unable to find line starting with "HTTP"
Posted by Eric Johnson <er...@tibco.com>.
Juan,
The one technique that I'm aware of for guaranteeing that the server
only processes the request once is to put in some sort of transaction ID
into the request, and the server will reject duplicate requests
(hopefully with an appropriate error message).
In short, it is an "application" level problem, not something that
HttpClient can help you with at the transport level. HttpClient can
improve in ways that make such tricks needed less frequently, but it
cannot eliminate the need for them. Hopefully, in your case, you can
change the server code to support such a technique.
-Eric.

Hello,
In case it is a server side issue, I would like be sure that the server
hasn't processed my request because I'm posting non idempotent requests.
If I retry the request but the first one was really processed I could be
in troubles.
I guess there is not a simple solution for this.
I include an excerpt of my httpclient log, in case you can get further
information.
Thank you very much.

Most likely it is a server side issue. Take a look at this post. It
should explain the cause of the problem and can help find a fix for it

Juan,
please take a look at our logging guide:
http://jakarta.apache.org/commons/httpclient/logging.html
Try and get a wirelog of the communication. That will help to track down
the problem.
Cheers
