selectionFailure in HelloWorld example

[Simon McClenahan <sm...@accertify.com>]

Hi,

I know it's not recommended but I have followed the tutorial for Eclipse BPEL Designer to create a Hello World BPEL deployed on Apache ODE. All seems well until I invoke the process method and I get a SOAP fault axis2ns268:selectionFailure . I have read http://ode.apache.org/assign.html and manually edited my HelloWorld.bpel to no avail.

When I turn on DEBUG for the server it says something about message being null, and from reading other posts on the list it probably means bad declared namespace. Can anyone help me where I've gone wrong?
