[jboss-user] [JBoss jBPM] - Problems with running the websale example

[petia]

Hi again,

Finally, I succeeded to install jbpm-jpdl-3.2.1 (through the jbpm-jpdl-suite-3.2.1.zip file). It is simple, but the installation direction in the jbpm-jpdl-3.2.1/designer/readme.html file could be improved by properly outlining the two installation options, i.e. ?run ant install? is only needed if one goes for the installation through ?run download eclipse? option. 

Anyway, now I am running into a new problem. I am executing the websale process provided with the installation. When I reach the ?deferred choice? i.e. I need to select between the alternatives ?End: More information needed? and ?End: OK? and I select one of them, I get the Exception report attached below.

I assume the example is correct and that I am doing something wrong. What am I doing wrong? (If more information is needed I am happy to provide it.)

Kind regards, Petia

PS I am also getting the following warnings when starting the server.
[FromElementType] Using non-qualified column reference [processInstance ->([PROCESSINSTANCE_])
[FromElementType] Using non-qualified column reference [isSuspended -> ([ISSUSPENDED_])
[FromElementType] Using non-qualified column reference [tiken -> ([TOKEN_])
[FromElementType] Using non-qualified column reference [id -> ([ID_])
[FromElementType] Using non-qualified column reference [processInstance -> ([PROCESSINSTANCE_])
[FromElementType] Using non-qualified column reference [isSuspended -> ([ISSUSPENDED_])
[FromElementType] Using non-qualified column reference [tiken -> ([TOKEN_])
[FromElementType] Using non-qualified column reference [processInstance -> ([PROCESSINSTANCE_])

Maybe, I still have not got the installation right.
I am grateful for any help.
