Received HTTP response code 400 : bad http request

[alejandro_gmez]

Hi all:

I'm trying to connect to my XI server using an RFC in my SAP Development environment. For test, I'm using SE37 tcode.

I've configured all in XI (Integration Builder: configuration and design). After using SE37, I obtain an error message:

**************************************************************************************************************************

It was obtained from one of the RFC trace files.

Thanks in advance (and excuse my bad English),

Hi Alejandro Gómez ,

In HTTP status code list the 4xx class of status code is intended for cases in which the client seems to have erred. Except when responding to a HEAD request, the server SHOULD include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. These status codes are applicable to any request method. User agents SHOULD display any included entity to the user.

If the client is sending data, a server implementation using TCP SHOULD be careful to ensure that the client acknowledges receipt of the packet(s) containing the response, before the server closes the input connection. If the client continues sending data to the server after the close, the server's TCP stack will send a reset packet to the client, which may erase the client's unacknowledged input buffers before they can be read and interpreted by the HTTP application.

HTTP 400 stands for Bad Request

This code indicates that the server could not understand the client's request, or found it to be incorrect in some way.

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.
