2:17 a.m.
Hello,
I' working with Eclipse europa and the Eclipse BPEL Designer Runtimes 0.2.0.
The server is jBoss 4.0.5 GA with jbpm-bpel-1.1.GA.
I'm developing a very simple bpel process with an invocation to a external web service
(the ticket service of the atm example).
I have the following files:
ticket.wsdl greet.wsdl greetArtifacts.wsdl greet.bpel greet.bpelex WsClient.java
Desc of each file
Ticket.wsdl: interface to ticket web-service
greet.bpel: process file
greet.bpelex: bpel extensions file (automatically generated)
greet.wsdl: interface to bpel process
greetArtifacts.wsdl: automatically generated
WsClient.java: Java client program to invoke the service
Code of each file:
-----------------------------greet.bpel--------------------------------------------

program, following exceptions occur in java console:
