Subject fault selection error (variable intialization problem)
Date Thu, 17 Sep 2009 14:27:20 GMT
hi to all,


i have a problem.. i try to exec a bpel process into Ode. I deploy 
it into ode then i invoke it sending the soap with the soap utility into bin 
directory of ode distribution, or with a jax-ws client. I dvelop using netbeans 
than i copy bpel, wsdl, xsd and deploy.xml files into process directory. The 
bpel is a receive and reply: receive a string and reply with the same.
During 
the replay i have to copy from input variable of receive statment to output var 
of reply (because variable are complextype [SOAP message type] i copy the 
simple elements
of them with XPATH) but i get fault selection problem.

My 
error fault is (i set the debug level in log4j properties
#line added
log4j.
category.org.apache.ode=DEBUG):

15:49:48,318 INFO  [ASSIGN] Assignment Fault:

In netbeans the bpel 
compiler tell me that "insertMissingToData is not allowed appear in element 
copy"..but i supposed that the fault problem message and the previous old ones 
that are the same of this last, are
about the output variable of reply (Out) 
that isn't initialized correctly (Out is a type of soap message that is a 
complex type)
So i read specification on : http://ode.apache.org/flexible-
assigns.html and i added insertMissingToData to copy element but the fault 
message still remain the same!

i have tried add an explicit assignement 
without insertMissingToData in the second copy element :

 <copy>

                <from><literal>0</literal></from>
                <to variable="
Out" part="parameters">
                    <query>myxsd:return</query>

                </to>
            </copy>

but i get the same problem:

15:04:
23,192 DEBUG [ASSIGN] Assign.copy({OCopy {VarRef {Variable __PROCESS_SCOPE:
