Hi,
we are using, jboss4.2.3GA as app server and jbpm-bpel-1.1.1 for JBPM'S BPEL for orchestration of webservices. we have one webservice running on another machine in tomcat. when we tried to access that webservice, it is giving the below exception stack..

16:20:17,734 ERROR [GraphElement] action threw exception: no port implements the required port type: portType={http://jbpm.org/examples/converter}CurrencyConverter
org.jbpm.bpel.BpelException: no port implements the required port type: portType={http://jbpm.org/examples/converter}CurrencyConverter
