Submission only works once (java.net.ConnectException on second try)

Hi,
I've had problems with submissions throwing "ERROR XFormsServer  - XForms - submission - xforms-submit-error throwable: java.net.ConnectException: Connection refused" on production enviroment.

I've few controls that have xforms-value-changed actions that send submission like this:
<xforms:submission id="modelToForm" method="post" ref="instance('dataTemp')" replace="instance" instance="response" action="/myApp/SomeXPL"/>

When forms loads those controls make xforms-value-changed events and I can see from log that it succeeds=
2008-03-20 14:35:36,935 INFO  ProcessorService  - /myApp/SomeXPL - Received request

Now when I edit that field again and focus some other control, control fires xforms-value-changed again and same action is processed. This time it doesn't happen, log says:

2008-03-20 14:36:21,585 INFO  ProcessorService  - /xforms-server - Received request

Do you think that there is something specific here to this
environment? Can you reproduce this when running the application on a
test environment? Can you see of this is somehow related to the use of
SSL?

I would put a tcpmon between the XForms server and the service
(http://ws.apache.org/commons/tcpmon/) to see exactly what is going on
the wire there. The error says "connection refused", which seems to
indicate that the TCP/IP connection could not even be made. If this is
the case, that would not be related to cookie or header forwarding.

One more question: what is the OS of the server? If you are on
Windows, I am wondering if you could be hitting this one:

It's got something to do with the enviroment, not sure what. I've never seen that exception with my devepment enviroment. It's not ssl-related, it has been tested without it and it gives same exception (only callstack differs).

Exception occurs only with 2 xpl:s and their contents are almost equal, maybe some kind of miss-configuration?
XPLs invoke custom processors and xpls have very simple syntax:

<p:config xmlns:customxpl="http://www.xxxxxxx.com/orbeon/processors" xmlns:p="http://www.orbeon.com/oxf/pipeline" xmlns:oxf="http://www.orbeon.com/oxf/processors" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema">

        <p:param type="input" name="instance" />

        <p:processor name="customxpl:CheckSQD_ID">
                <p:input name="data" href="#instance"/>
                <p:output name="boolean" id="ba_output"/>
        </p:processor>

        <p:processor name="oxf:xml-serializer">
                <p:input name="data" href="#ba_output" />
                <p:input name="config">
                        <config>
                                <content-type>application/xml</content-type>
                                <cache-control>
                                        <use-local-cache>false</use-local-cache>
                                </cache-control>
                        </config>
                </p:input>
        </p:processor>

</p:config>

Excellent, I'm glad you found the source of the problem. And tcpmon is  
the king here! :)
