NEW POST: Unable to Execute the Process

skumaar — Tue, 26 Jun 2007 08:43:04 GMT

Hi,
Thank you very much for your immediate help regarding how to run the engine. Some how I was able to do and presently i'm facing the next level issue. I deployed a simple process called add to number process who's bpel is as follows,
------------------------------------------
BPEL
***********
<process name="AddTwoNumProcess" expressionLanguage="" enableInstanceCompensation="no" suppressJoinFailure="no" xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://AddNumDefs" targetNamespace="http://AddNumDefs" xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"><partnerLinks><partnerLink name="AddNumPLink" myRole="AddNumPLinkRole" partnerLinkType="tns:AddNumPLink" /></partnerLinks><variables><variable name="AddTwoNumSoapIn" messageType="tns:AddTwoNumSoapIn" /><variable name="AddTwoNumSoapOut" messageType="tns:AddTwoNumSoapOut" /></variables><sequence><receive createInstance="yes" name="StartEvent" partnerLink="AddNumPLink" portType="tns:AddNumPLinkPort" operation="AddTwoNum" variable="AddTwoNumSoapIn" /><assign><copy><from expression="bpws:getVariableData('AddTwoNumSoapIn', 'parameters','/tns:AddTwoNum/tns:x') + bpws:getVariableData('AddTwoNumSoapIn', 'parameters','/tns:AddTwoNum/tns:y')" /><to variable="AddTwoNumSoapOut" part="parameters" query="/tns:AddTwoNumResponse/tns:z" /></copy></assign><reply name="EndEvent" partnerLink="AddNumPLink" portType="tns:AddNumPLinkPort" operation="AddTwoNum" variable="AddTwoNumSoapOut" /></sequence></process>
---------------------------------------

Its WSDL is as follows,
------------------------------------------
WSDL
----------
<definitions targetNamespace="http://AddNumDefs" xmlns:tns="http://AddNumDefs" xmlns:slt="http://schemas.xmlsoap.org/ws/2003/03/service-link/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:plnk="http://schemas.xmlsoap.org/ws/2003/05/partner-link/" xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/" xmlns="http://schemas.xmlsoap.org/wsdl/"><wsdl:types><xsd:schema elementFormDefault="qualified" targetNamespace="http://AddNumDefs"><xsd:element name="AddTwoNum"><xsd:complexType><xsd:sequence><xsd:element minOccurs="1" maxOccurs="1" name="x" type="xsd:int" /><xsd:element minOccurs="1" maxOccurs="1" name="y" type="xsd:int" /></xsd:sequence></xsd:complexType></xsd:element><xsd:element name="AddTwoNumResponse"><xsd:complexType><xsd:sequence><xsd:element minOccurs="1" maxOccurs="1" name="z" type="xsd:int" /></xsd:sequence></xsd:complexType></xsd:element></xsd:schema></wsdl:types><wsdl:message name="AddTwoNumSoapIn"><wsdl:part name="parameters" element="tns:AddTwoNum" /></wsdl:message><wsdl:message name="AddTwoNumSoapOut"><wsdl:part name="parameters" element="tns:AddTwoNumResponse" /></wsdl:message><wsdl:portType name="AddNumPLinkPort"><wsdl:operation name="AddTwoNum"><wsdl:input message="tns:AddTwoNumSoapIn" /><wsdl:output message="tns:AddTwoNumSoapOut" /></wsdl:operation></wsdl:portType><plnk:partnerLinkType name="AddNumPLink"><plnk:role name="AddNumPLinkRole"><plnk:portType name="tns:AddNumPLinkPort" /></plnk:role></plnk:partnerLinkType></definitions>
--------------------------------

After running the process I deployed this WSDL and BPEL and it created ashx file. Then created a proxy class in my client application and passed the parameters whoes SOAP message is as follows,

----------------
SOAP Message

<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><soap:Body><AddTwoNum xmlns=\"http://AddNumDefs\"><x>10</x><y>20</y></AddTwoNum></soap:Body></soap:Envelope>

--------------------

Here is my problem,
1. When we look into the process definition I used "Parameters" as a part in my xpath which is not supplied there. But the same is happening when I execute the same with other engine (ActiveBPEL).
2. Also the variable values are not assigned in the current context object. While debugging I came to know that it's passed as null in the processcontroller.cs as mentioned below,
//Cretae variable in the context for easy access
instance.ContextList.Context.AddVariable(element.Name, null);
3. And finally I came across one situation which returns a null value for the object val from the below expression in Process controller.cs
object val = ExpressionEvaluatorHelper.EvaluateExpression(element.Expression, instance);

I hope i'm doing something, so it could be really great if you help me regarding this. Also, I don't know where we are really mapping the service name, webservice url and URI mappings as it's not been used so far or am i'm doing something wrong?

Thanks and regards,
Kumar

Created working branch to work on Instance. This area need to be refactored in order to move responsability from Instance to more focused classes.

Thank you for your interest.
You can compile the project using VS 2005.
Make sure ws-ore-admin is setup in IIS as a virtual directory
Optionaly change the the ws-ore-admin web.config to match your system
From within VS set the ws-ore-admin as the startup project hit run and voila.
Fill in the values in the form if all goes well the ws-ore will generate a .ashx file
Send the appropriate SOAP messages to this handler and it should execute your BPEL orchestration.
