NPE in PartnerRoleMessageExchangeImpl createPartnerRoleMex()
------------------------------------------------------------
Key: ODE-205
URL: https://issues.apache.org/jira/browse/ODE-205
Project: ODE
Issue Type: Bug
Components: BPEL Runtime
Reporter: Alex Boisvert
Assignee: Maciej Szefler
On the ode-user mailing list, Thilina Gunarathne reported the following:
http://mail-archives.apache.org/mod_mbox/ode-user/200710.mbox/[EMAIL PROTECTED]
(This applies to the -trunk)
I tried to modify the HelloWorld sample to invoke an external service.
The external service was invoked successfully and the response was
received to ODE..
At this point the process fails with a NPE.
PartnerLinkPartnerRoleImpl line 62..
PartnerRoleMessageExchangeImpl createPartnerRoleMex(MessageExchangeDAO mexdao) {
InvocationStyle istyle = mexdao.getInvocationStyle();
......
switch (istyle) {
NPE occurs due to the style being NULL.
Am I doing anything wrong?.. (BPEL & the WSDL docs are attached).
But IMHO the NPE needs be checked and should throw a meaningful
exception.. Also the value for getInvocationStyle() in all of the
MessageExchangeDAO implementations have the possibility to be NULL..
thanks,
Thilina
