By the way your blog was also very helpful %) Everything's clear about interactions. > Try to avoid using script nodes. Is it ok to use Script Nodes to make thing like "user = String.valueOf(userBean.Name) + "-" + String.valueOf(userBean.Id);"? > Regarding the operations with the DB which seems to be transactional, it > depends on how do you want to do it. If you start a transaction against your > DB inside a workItemHandler and then write the logic to see if everything > else went right and commit that transaction, everythhing should work. Could you clarify some things about DB: I found "Data Object" elements in eclipse designer palette, is it something concerning data access? Or what are they made for? It confuses me a little. > Notice that for what you describe, you don't need to persist your "Flows" > because all what you need is to execute the steps and commit or rollback the > information to another external database. Also, concerning persistence and clustering: if I persist my flow instance, does it provide the ability to restart flow from the point it was persisted after system crash/shutdown and restoration to operational state? Could it be configured (coded?) to failover process instances to other running system restoring states from persistent store? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/825529#825529] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
