I'm very new to Jbpm. After impressed by Jbpm starter kit, I decide to try manually install Jbpm into Jboss4.0.3SP1 with MySQL5. Everything seems to be okay. No error in the console. But I notice a different from Jbpm in the starter kit. There're no CommandExecutorThread, DbPersistenceServiceFactory, SchedulerThread running every 5 seconds. I follow the following steps to deploy Jbpm. 1) run jbpm-db/build/mysql/scripts/mysql.create.sql 2) deploy jbpm-ds.xml to connect to mysql, and put mysql jdbc driver into $jboss_home/server/default/lib 3) deploy jbpm.sar and point the config to jbpm datasource. 4) deploy process by using ant task 5) deploy a simple war to test. I can successfully get the current JbpmContext and findLatestProcessDefinitions. Is the CommandExecutorThread required? and How to configure it to run?
