oxf:delegation with porlet

Hi.
I'm having difficulties using oxf:delegation for consuming web services when orbeon xforms is used within liferay portal.

oxf:delegation outputs this exception to ops.log:

Liferay's version is 4.3.4 and Orbeon's is orbeon-3.6.0.200712061930

Similar problem occurs without liferay, just tomcat 5.5+orbeon and oxf:delegation gives=

I'm sending whole instance to another server to process it. Webservice call works with xforms:submission but it's not preferable method for me because I need to do some xslt for the instance before sending it.

Liferay's version is 4.3.4 and Orbeon's is orbeon-3.6.0.200712061930

One way around this is to submit the instance to a service (XPL) that does the transformation, returns the transformed XML to XForms that you store in another instance, and submit from XForms with an xforms:submission to the Web service. Independently of the issue with the delegation processor, I would implement this that way as using an xforms:submission is the prefered way to call a web service.

Would you be able to create and share with us a simple example with just one XHTML and one XPL file, both in a directory under apps? This would help us to reproduce this problem.

Your solution sounds great alternative. How do I send it automatically when flow return from that specific xpl to xforms?

I managed to do xforms:send when xforms-ready event occurs but it does it when I use other xpls. Is there a way to control it to do submission only when previous page-flow was xxxyyy.xpl?

I am not sure that I understand what your question is. Just to clarify, you would do in a sequence of actions:

<xforms:send submission="submission-that-transforms-the-instance"/>
<xforms:send submission="submission-that-submits-the-instance-to-web-service"/>

Does this help?

Alex

Ok, I can do multiple submits like that :)

That helped, thanks!

Note that an alternative is to call the XPL that does transformation directly from XPath using xxforms:call-xpl(). You would then use an <xforms:insert origin="xxforms:call-xpl(...)"> instead of the first submission. On the upside, this is simpler (no need to have an additional <xforms:submission>, and entry in the page flow) and this is potentially faster. On the downside, you need to use an Orbeon-specific XForms extension.
