unable to find line starting with "HTTP"
Hi, Folks,
I am using HttpClient 3.1,
The code is simple:
HttpClient client = new HttpClient();
GetMethod method = new GetMethod( myURL );
byte[] responseBody = method.getResponseBody();
When I sent a short a url string with few parameters , it works fine.
But when I sent a very long url string with too many parameters,
I got this exception:
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)

org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:6

I wonder if a heavy load in server site? How to fix this issue?
Thank you very much, Please help.

For example these following parameters I need to contains them in url.
If cut them to half, it works fine. But if not, I got "unable to find

I assume there's also a call to HttpClient.execute somewhere :-)

There are practical limits to the length of a URL, which are
(server) implementation dependent. That's why you send long
or many parameters in the message body, either form-url-encoded
or as multipart-mime. If the server application is a Servlet,
it won't make any difference.

This indicates that the server is sending nonsense. Since you
know the reason, there is no point in further analysis.

These are not parameters. Parameters look like "?n1=v1&n2=v2".
Don't put that stuff in the URL, it is way too big. There is no
way you can get that across reliably with a GET request. The
primer has a few short paragraphs about creating POST requests
and the two primary options for encoding parameters:
http://wiki.apache.org/jakarta-httpclient/ForAbsoluteBeginners#head-8ce973d0347a2eba238f594c47f478035c51ea66
Here are some starters in the JavaDoc:
http://jakarta.apache.org/commons/httpclient/apidocs/org/apache/commons/httpclient/methods/PostMethod.html#addParameter(java.lang.String,%20java.lang.String)
http://jakarta.apache.org/commons/httpclient/apidocs/org/apache/commons/httpclient/methods/multipart/MultipartRequestEntity.html
Decide on one of the two. You can't mix a multipart request entity
with parameters added directly to the PostMethod.
hope that helps,
Roland

By the way: do NOT cross-post your problems into multiple mailing lists!
This is mentioned twice in the Jakarta mailing list guidelines.
