[jboss-user] [jBPM] - Using jBPM as state machine engine - is it a good idea?

To view the discussion, visit: https://community.jboss.org/message/778239#778239 -------------------------------------------------------------- Hi, I usualy have a database oriented application, which stores records, where one field of the record (one column in a row in database) stores something called "state" - eg. record is "new", "revised", "waiting for approval" or "cancelled". The state of the record should change automatically according to changes in other fields of the record - eg. if someone changes a description of a "new" record, it should be changed to "revised" but if amount > 100 than it should go to "waiting for approval" instead. I would like to have some library where I could in case of record update do something like this (pseudo-code): Process process = createProcesFromDefinition("mydefinition.process"); process.setCurrentState(getStateFromDatabase()); process.setOldRecord(getRecordFromDatabase()); process.setNewRecord(getRecordWhichIsToBeSaved()); State state = process.computeResultingState(); storeStateToDatabase(state); I would like to have the process definition in some kind of XML format, and the rules for decision about the resulting transition in MVEL (or something else supported by Drools/JBoss Rules). Is it possible to use jBPM in this way - just as a state machine engine? Could someone point me in the right direction, which classes should I explore in the jBPM API to do this? I have seen some examples, but they always start the process from the beginning - but I would like to "fast forward" the process in some other state, provide some data, and let the engine&rules to choose the next state.
