Subject Error when invoke Web service from BPEL
Date Tue, 28 Oct 2008 20:27:47 GMT
Hi everyone,
I have a Web Service having the operation *reverse* to reverse a string.
This WS works well when tried with a Java program client, but when invoked
from a BPEL,
I encounter the following error (I use ODE 1.2 for BPEL Engine run in Tomcat
5.5;
I tried to deploy the Web service in both Tomcat 5.5 and 6 but the same
error):
