A problem with initiating a BPEL process through its web service interface

Question

hi,
i am trying to initiate the helloWorld BPEL process through its web service interface. i use a proxy class that i wrote and i use it from J#.net.
this is the relevant code part:
hello.HelloWorldBinding wsProxy = new hello.HelloWorldBinding();
wsProxy.initiate("Hello");
and the server shows the following message:
ORABPEL-05002
Message handle error.
An exception occurred while attempting to process the message "com.collaxa.cube.
engine.dispatch.message.invoke.InvokeInstanceMessage"; the exception is: Cannot
decode properties.
The process domain was unable to decode the properties for message guid 10, whic
h are stored in column String index out of range: 3094; the exception reported i
s: {2}.
sql statement: SELECT conv_id, message_guid, domain_ref, process_id, revision_ta
g, operation_name, receive_date, state, priority, properties FROM invoke_message
WHERE message_guid = ?

what is the problem? how come i can't initiate the process?
i will be happy if i could get help..
thanks in advance

Answer 1

can you initate the process from the bpel console successfully?
if so can you use obtunnel from the installation to trace the soap message (that goes over the wire), my best guess in this case is a problem with a header (holding the wsa information) ..
after starting obtunnel it will liesten to a custom port, and will forward the request to the engine, so you need to point your client to this new port..
