invoke example
Dear Community,
Can anybody provide an example on how to use an invoke operation. I am having problems with the invoke operation. The engine complain with a BPEL Fault, uninitializedPartnerRole
My BPEL code is:
<?xml version="1.0" encoding="UTF-8"?>
<process name="helloWorld" targetNamespace="http://jbpm.org/examples/hello"
xmlns:tns="http://jbpm.org/examples/hello"
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-process/
http://schemas.xmlsoap.org/ws/2003/03/business-process/"
xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
xmlns:impl="http://myapp.com" >
<partnerLinks>
<!-- realizes the abstract relationship with the caller -->
<partnerLink name="caller" partnerLinkType="tns:ROinPLT"
myRole="service"/>
<!--<partnerLink name="sendData" partnerLinkType="tns:ROinsendDataPLT"
myRole="service"/>-->
<partnerLink name="getData" partnerLinkType="tns:GoandGetLink"
partnerRole="service"/>
</partnerLinks>
<variables>
<!-- holds the incoming message -->
<variable name="processID" messageType="tns:processIDMessage"/>
<!-- holds the outgoing message -->
<variable name="return" messageType="tns:returnMessage"/>
<variable name="getDataInput" messageType="impl:getDataRequest"/>
<variable name="getDataOutput" messageType="impl:getDataResponse"/>
</variables>
<sequence>
<!-- receive a message carrying the name of a person -->
<receive operation="initiate" partnerLink="caller"
portType="tns:ROinPT" variable="processID" createInstance="yes"/>
<!-- compose a greeting phrase containing the name -->
<!--<assign>
<copy>
<from expression="concat('Hello, ',
bpel:getVariableData('processID', 'processID'), '!')"/>
<to variable="return" part="return"/>
</copy>
</assign>-->
<assign name="copyID1">
<copy>
<from expression="bpel:getVariableData('processID', 'processID')"/>
<to variable="return" part="return"/>
</copy>
</assign>
<assign name="copyID">
<copy>
<from expression="bpel:getVariableData('processID', 'processID')"/>
<to variable="getDataInput" part="in0"/>
</copy>
</assign>
<invoke name="getData" inputVariable="getDataInput"
partnerLink="getData" operation="getData" portType="impl:GoandGet"
outputVariable="getDataOutput">
</invoke>
<!--<assign name="copygetDataOutput">
<copy>
<from variable="getDataOutput"/>
<to variable="return" part="return"/>
</copy>
</assign>-->
<!-- reply with a message carrying the greeting -->
<reply operation="initiate" partnerLink="caller" portType="tns:ROinPT"
variable="return"/>
</sequence>
</process>
my wsdl files is:
<?xml version="1.0" encoding="UTF-8"?> <definitions targetNamespace="http://jbpm.org/examples/hello" xmlns:tns="http://jbpm.org/examples/hello" xmlns:impl="http://myapp.com" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:plt="http://schemas.xmlsoap.org/ws/2003/05/partner-link/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:bpel="http://schemas.xmlsoap.org/ws/2003/03/business-process/" xsi:schemaLocation="http://schemas.xmlsoap.org/wsdl/ "> <import namespace="http://myapp.com" location="http://localhost:8080/ws4ee-jbpm2/exactpath/jse?wsdl"/> <!--<import namespace="http://myapp.com" location="services/goandget.wsdl"/>--> <plt:partnerLinkType name="GoandGetLink"> <plt:role name="service"> <plt:portType name="impl:GoandGet"/> </plt:role> </plt:partnerLinkType> <!-- characterizes the relationship between the process and its caller --> <plt:partnerLinkType name="ROinPLT"> <plt:role name="service"> <plt:portType name="tns:ROinPT"/> </plt:role> </plt:partnerLinkType> <message name="processIDMessage"> <part name="processID" type="xsd:string"/> </message> <message name="returnMessage"> <part name="return" type="xsd:string"/> </message> <portType name="ROinPT"> <operation name="initiate"> <input message="tns:processIDMessage"/> <output message="tns:returnMessage"/> </operation> </portType> <!-- carries the name of a person --> <!-- carries the greeting --> <!-- describes the interface presented to callers --> </definitions>
and the bpel-definition file is:
<?xml version="1.0" encoding="UTF-8"?> <!-- specifies the location of the process definition --> <bpelDefinition location="hello.bpel" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jbpm.org/bpel http://jbpm.org/bpel/bpel_definition_1_0.xsd" xmlns="http://jbpm.org/bpel" > <!-- makes WSDL interface elements available to the process --> <imports> <wsdl namespace="http://jbpm.org/examples/hello" location="hello.wsdl"/> <wsdl namespace="http://myapp.com" location="http://localhost:8080/ws4ee-jbpm2/exactpath/jse?wsdl"/> <!--<wsdl namespace="http://myapp.com" location="C:\Java\jbpm-bpel-1.0-alpha3\doc\examples\hello\definition\services\goandget.wsdl"/>--> </imports> </bpelDefinition>
As you can see the deploy goes ok, but whet i try to run the client i get this exception
