Ok,

For now I found the solution about building the XPL that will call the webservice and send the appropriate parameters. What I don't know for now is how to send/receive the XML content to/from webservice, since SOAP is not able to handle XML content in the parameters (or at least I don't know how to do make it to accept XML content in the in/out parameters). 

I was thinking to encode/decode the XML before and after calling the webservice. Is this a good idea?

Here is how my XLP looks like:

<p:param name="formData" type="input" debug="form-data"/> 

<p:param name="checkMessages" type="output"/>

<p:processor name="oxf:xslt">

<p:input name="data" href="#formData" />

<p:input name="config">

<xsl:stylesheet version="2.0">

<xsl:template match="/">

<xsl:element name="delegation:execute">

<xsl:attribute name="service">check-form</xsl:attribute>

<xsl:attribute name="operation">checkForm</xsl:attribute>

<xsl:element name="id0">

<xsl:value-of select="/user-response/sapRequestId"/> 

</xsl:element>

<xsl:element name="id1" >

<xsl:copy-of select="/user-response/updatedXformModel"/>

</xsl:element>

</xsl:element>

</xsl:template>

</xsl:stylesheet>

</p:input>

<p:output name="data" id="sub-pipeline-config" />

</p:processor> 

<p:processor name="oxf:delegation">

<p:input name="formData" href="#formData" debug="form-data"/>

<p:input name="interface">

<config>

<service id="check-form" type="webservice" style="rpc"

endpoint="http://localhost:13569/InvoiceCyclePSNV/services/CheckFormController">

<operation nsuri="urn:avernet" name="checkForm" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>

</service>

</config>

</p:input>

<p:input name="call" href="#sub-pipeline-config"/> 

<p:output name="checkMessages" ref="checkMessages" />

</p:processor>

regards,

Alexandru

Hello Erik,

thanks for your reply.

Meanwhile I have changed my logic and what I'm trying to do now is to call a pipeline with two input parameters like this:

<xf:insert nodeset="instance('formCheckMessages')"

               origin="xxforms:call-xpl(

               '<%=StringUtils.getRemoteXplProcessor(StringUtils.CHECK_FORM_PROCESSOR) %>', 

               ('requestId','formData'), 

               (instance('userResponse')/sapRequestId, instance('content')), 'checkMessages')"/>

and the pipe line is like this:

<p:config xmlns:p="http://www.orbeon.com/oxf/pipeline"

xmlns:oxf="http://www.orbeon.com/oxf/processors"

xmlns:delegation="http://orbeon.org/oxf/xml/delegation"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:xs="http://www.w3.org/2001/XMLSchema"

xmlns:m="http://localhost:13569/InvoiceCyclePSNV/services/CheckFormController">

<p:param name="requestId" type="input" debug="req-id"/> 

<p:param name="formData" type="input" debug="form-data"/> 

<p:param name="checkMessages" type="output"/> 

<p:processor name="oxf:delegation">

<p:input name="requestId" href="#requestId" debug="req-id"/>

<p:input name="formData" href="#formData" debug="form-data"/>

<p:input name="interface">

<config>

<service id="check-form" type="webservice" style="document"

endpoint="http://localhost:13569/InvoiceCyclePSNV/services/CheckFormController">

<operation name="checkForm" soap-action="checkForm" />

</service>

</config>

</p:input>

<p:input name="call">

<delegation:execute service="check-form" operation="checkForm">

<m:checkForm>

<m:requestId></m:requestId>

<m:formData></m:formData>

</m:checkForm>

</delegation:execute>

</p:input>

<p:output name="checkMessages" ref="checkMessages" />

</p:processor>

</p:config>

but my problem now is that I don't know how to refer these two input parameters inside the webservice call. The first one, requestId, is a long variable and the second, formData, is a xml instance that is backing the xform and I want to send it as it is (xml) to the webservice.

Thanks and regards,

Alexandru

Alexandru,

Something like this should work:

<xf:submission id="postResponse" method="post"

ref="instance('aggregate')" action="/service/dispatchRequest.do">
   <xforms:action ev:event="xforms-submit">
       <xf:delete nodeset="instance('aggregate')/*"/>
       <xf:insert context="instance('aggregate')" nodeset="*"
origin="instance('userResponse')"/>
       <xf:insert context="instance('aggregate')" nodeset="*"
origin="instance('initialData')"/>
   </xforms:action>
</xf:submission>

<xf:instance id="aggregate">
 <response/>
</xf:instance>

Re. question 2, yes it's possible. You can do this with 2 submissions:

* 1st one submits data to your service implemented in XPL and
retrieves the result
* Upon 1st submission's xforms-submit-done, send 2nd submission
