WSIFException: No Method Found

Question

We are very interested in implementing the WSIF call from BPEL and I have been following the samples (anthony reynold's blog) very carefully and I cannot get around this error. I have a very simple interaction and I am hoping someone may have some insight. There was one instance of a similar issue, but there didn't seem to be any resolution, hence the reason I am posting my query.

Answer 1

WSIF is mainly used in the context of BPEL - you may get better help from the BPEL forum: BPEL
Hope it helps,
