Good evening. I am struggeling with the following task and would appreciate help with it.
Setting is Proxy->SOAP, problem is in the Module Chain of the SOAP Receiver Channel.
I have to satisfy the security requirements of an external WebService I need to consume. I have configured the following steps in my scenario:
1. Fetch a SAML Security Token from another Service in a previous call (using a X.509 certificate to sign the request) and hold it in the ABAP Backend.
2. Send this Security Token together with request data from ABAP to PO.
3. In PO, first do an XSLT Mapping in the Interface Determination part of the ICO to create a SOAP header and put the Security Token into this header. (And to map some other things, which are not important here.)
4. Then this is passed to a SOAP Receiver Channel with "Do Not Use SOAP Envelope" checked.
I configured the following Module Chain:

I need the AxInvokerBean to call WSDoAllSender to add a Timestamp and sign Timestamp and Body with a certificate from the Keystore. This works fine.
Then the payload looks like:
Envelope
- Header
- - Security
- - - Signature
- - - Timestamp
- - SAML Token
- Body
But I need this:
Envelope
- Header
- - Security
- - - SAML Token
- - - Signature
- - - Timestamp
- Body
In other words: I have to put the SAML Token inside of the Security node. To achieve this, I created a small XSLT Mapping and call it using MessageTransformBean:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0">
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="saml:Assertion"/>
<xsl:template match="wsse:Security">
<wsse:Security>
<xsl:copy-of select="/soap:Envelope/soap:Header/saml:Assertion"/>
<xsl:apply-templates/>
</wsse:Security>
</xsl:template>
</xsl:stylesheet>
(I deleted all the namespace declarations to make it easier to read, but in real life, they are there). During development, I save the payload before each module call using AxInvokerBean and LogHandler.
This Mapping is the last step I need to call this WebService. If I put the payload which comes out of AxInvoker into the xslt in eclipse, it produces what I want to have. This is NOT an xslt question.
And finally my PROBLEM:
In this Module Chain, the xslt simply does nothing, the payload looks the same before and after the call (except for some whitespaces). I can see in xpi_inspector that it is found and called and the transformation is "executed successfully", but it just does not do anything, and I am out of ideas why.
Thank you!
