Hi,

I am trying to call a SOAP service (Paypal, using "post") with the
send-request() method of the HTTP Client module in eXist, taking inspiration
from this example [1]. However the result is that I get a "411 Length Required"
error. Note that the request endpoint is an HTTPS endpoint
("https://api-3t.sandbox.paypal.com/2.0/").

Here is the beginning of the $req object that I send using
http:send-request($req) :

<http:request href="https://api-3t.sandbox.paypal.com/2.0/" method="post"> <http:header name="SOAPAction" value="SetExpressCheckout"/> <http:body media-type="text/xml"> ...

Note that if I try to manually set a Content-length by adding a header to the
request with an arbitrary value:

<http:header name="Content-length" value="1000"/>

Then I get an exception from the HTTP Client module :

Error found Error executing the HTTP method Java Stack Trace:Class Name Method Name File Name Line org.expath.exist.SendRequestFunction sendRequest SendRequestFunction.java 150

So I would like to know if the http:send-request method sets the Content-lenght
header, and if not how to set it manually ?

Note that to import the HTTP Client module with eXist 1.4.1-rev15155, I had to
comment the following lines in 'conf.xml' (taking ideas from this thread [2]),
since otherwise XQuery throws an exception. I guess eXist 1.4.2. does not fix
the problem either, since it still contains the old "http-client.xqm" module
uncommented in conf.xml.

<!-- EXPath Modules --> <module uri="http://expath.org/ns/http-client"
class="org.expath.exist.HttpClientModule" /> <!-- <module uri="http://www.expath.org/mod/http-client"
src="resource:org/expath/www/mod/http-client/http-client.xqm" /> -->

<!-- Native EXPath HTTPClient Module --> <!-- <module uri="http://exist-db.org/xquery/httpclient"
class="org.exist.xquery.modules.httpclient.HTTPClientModule" /> -->

When setting up conf.xml as above, you can then load the HTTP Client module
without throwing an exception using: import module namespace http = "http://expath.org/ns/http-client";

Thanks in advance for any help,

Stéphane S.
