Unable to access wsdl part from the variable defined by wsdl
Hi,
I'm working with ODE 1.0. I have a problem with getting the WSDL part
from variable associtated with WSDL's message. Please find below
extracts from WSDL, BPEL script and Service Mix logs associated with
initilazing the $SabreCommandRequest variable.
The SabreCommandRequest variable is created by copying the XSL output to
the body part of the SabreCommandRequest variable (see Bpel Script). You
may see from the logs that xsl returns the following xml :
<?xml version="1.0" encoding="UTF-8"?>
<SabreCommandLLSRQ xmlns="http://webservices.sabre.com/sabreXML/2003/07"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
Version="2003A.TsabreXML1.5.1">
<Request Output="SCREEN">
<HostCommand>N*(TEST)(SABRE_END_ITEM)NM</HostCommand>
</Request>
</SabreCommandLLSRQ>
However, when the above xml is copied to SabreCommandRequest ( <bpel:to
variable="SabreCommandRequest" part="body"/> ) the variable gets the
following form :
<?xmlversion="1.0" encoding="UTF-8"?>
<message><body><SabreCommandLLSRQ Version="2003A.TsabreXML1.5.1"
xmlns="http://webservices.sabre.com/sabreXML/2003/07"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Request Output="SCREEN">
<HostCommand>N*(TEST)(SABRE_END_ITEM)NM</HostCommand>
</Request>
</SabreCommandLLSRQ></body></message>'
Now, I want to verify that $SabreCommandRequest is created successfully,
simply I'm trying to check if SabreCommandLLSRQ node exists. When I
create XPath "$SabreCommandRequest.body/xsd1:SabreCommandLLSRQ" I see
the XPath expression returns false. I tried with xsd1 namespace and
without namespace, and all the time it's false.
DEBUG - XPath20ExpressionRuntime - Expression {OXPath10Expression
boolean($SabreCommandRequest
.body/xsd1:SabreCommandLLSRQ)} generated result false -
type=java.lang.Boolean
What I'm doing wrong ? I see that afer performing copy the variables is
encapsuleted by <message> and <body>. In case of a similar variable that
I'm getting from the <receive> activity the variable does not contain
the <message> and <body> and $Variable.body works well.
best regards

The format of the above is the internal message representation where
<message> is the root element used to wrap all message parts and <body>
is a
named part with its content.

The $message.part notation selects the top-level part element (if the
part
is an element) or an element wrapper (if the part is a schema type), so
if
you want to select the xsd1:SabreCommendLLSRQ element, you would simply
write "$SabreCommandRequest.body".
