4:42 a.m.
wrote a simple bpel code:
<?xml version="1.0" encoding="UTF-8"?>
<process name="review" targetNamespace="urn:author"
xmlns:urn="urn:author"
xmlns:rev="urn:reviewer"
xmlns:bpel="http://schemas.xmlsoap.org/ws/2003/03/business-process/&...
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://schemas.xmlsoap.org/ws/2003/03/business-p...
http://schemas.xmlsoap.org/ws/2003/03/business-process/"
xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"...
<!-- realizes the abstract relationship with the caller -->
<!-- realizes the relationship with the reviewer1 -->
<!-- holds the incoming message -->
<!-- holds the outgoing message -->
<!-- receive a message carrying the name of a person -->
<!-- reply with a message carrying the greeting -->
the corresponding wsdl is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="urn:author"
xmlns:urn="urn:author"
xmlns:rev="urn:reviewer"
xmlns="http://schemas.xmlsoap.org/wsdl/"

xmlns:plt="http://schemas.xmlsoap.org/ws/2003/05/partner-link/"

<!-- characterizes the relationship between the process and its caller -->
<plt:partnerLinkType name="callerPLT">

<plt:partnerLinkType name="reviewPLT">
<plt:role name="review">
<plt:portType name="rev:Reviewer"/>
</plt:role>
</plt:partnerLinkType>
<!-- describes the interface presented to callers-->
the rev.wsdl of the external web service used is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="urn:reviewer"

</wsdl:definitions>
in the "binding.xml" generated after generate-artifacts, the style has been
changed to document/literal. the web-service involved also supports doc/lit format.
the bpel process gets deployed. using wsdl2Java, the client is generated. i get the
following error:
