I have answered your question?

Do you suggest another way of doing this? Why do you usually avoid it? Thanks, Diogo. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/625718#625718] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

I've read the ch07 but I could not find examples on how to retrieve the ProcessInstanceLog/NodeInstanceLog objects. Can you please provide examples? Thanks. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/625758#625758] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

Using the java apis will probably not give you enough flexibility to have a query mechanism for all the situations.
