Hi,

We use the built-in ddtek:http-post method to send documents to a partner on a daily basis.
Unfortunately, the receiving server is often busy or closes our connection, causing an error such as this:

(host:172.16.0.74) Apr 25, 2023 2:22:08 PM com.ivitechnologies.pipeline.server.OperationXQuery runInternal
SEVERE: [I9][XQuery]java.net.SocketException: Connection reset
xquery uri file:/c:/xps/pipelines/xxx/xquery/Deliver2WS.xquery
input URL file:///E:/Nav-PipelineServer-DataExchange/FilesFromNavision/xxx/FR_5695448_20230425T142200.xml
operation properties:
annotation=false
rotate=270
Name=Deliver2WS.xquery
h=100
Operation=XQUERY
ID=25
y=143
.xquery file=..\xyx\xxx\Deliver2WS.xquery
x=882
w=140
XQPreparedExpression com.ivitechnologies.pipeline.concurrent.ObjectWithLock@4b3b7375
isClosed false
javax.xml.xquery.XQException: [I9][XQuery]java.net.SocketException: Connection reset

I tried to make this more error tolerant by adding these options to the request, but I am not finding that it makes a difference:

<header name="retries" value="5"/>
<header name="connection-timeout" value="12000"/>

Is there another way to handle this, can one make code that tries to resend?

As by now I need to resend from our ERP system, since the input file has been deleted at this point.

Kind regards

I do not think you are passing the options correctly, "retries", "socket-timeout" are attributes of element "request".

The headers are HTTP header inserted in the message that are sent to the server.

For the full list of options see chapter "Settings for Connections and Sockets" at

<Stylus Studio Install>
-\Components
--\DataDirect XQuery
---\books
----\ddxquery
-----\ddxqug
------\ddxqug.pdf

See example below

declare variable $options :=

<request
username="..."
password="..."
retries="3"
socket-timeout="30000">
<request-header>
<header name="Content-Type" value="text/xml"/>
</request-header>
</request>;

declare variable $url := "...";
declare variable $payload := "...";

ddtek:http-post($url, $payload, $options)

I have now added the attributes 'retries' and 'connection-timeout' to the request element.

Before that, I had tried to make it work by adding the values as header name value pairs.

Hopefully that makes the difference, thank you for helping me out here.
