5:11 a.m.
Sorry, because maybe it´s a stupid error. I´m a beginer, and I cannot understan all...
I've been trying to consume a WebService in BPEL 2.0 process with jbpm and the
following exception occurs. Any idea what's the problem?
11:47:03,840 WARN [ProxyWarnLog] Narrowing proxy to class
org.jbpm.bpel.graph.def.CompositeActivity - this operation breaks ==
11:47:03,872 ERROR [XPathEvaluator] selection of size other than one: []
I think is a bad assigment, but I´ve not idea. The webservice works good...
