Hi all,
first post here. I have deployed jBPM 3.2.7 on webpshere 7.0 and oracle 10g as
database. A simple process works fine for me. But when I deploy a process which contains a
state with timer on it I get the error shown below. Would really appreciate some help
here.
Thanks!

Turned out to be user error. WebSphere specific CMP to RDB mappings were incorrect. I did
the mapping by taking a look at jbosscmp-jdbc.xml. Now the timer works fine. But I see
another scheduler related error in WebSphere logs though it does not seem to affect the
processing.
