So, as an implementation example of all this (take in mind that ant is new stuff for me): To allow switching between JMS and DB based messaging, we could use a jbpm.cfg.xml file containing: <jbpm-configuration> | <jbpm-context> | <!--DB based Messaging (begin) == | <service name="message" factory="org.jbpm.msg.db.DbMessageService"/> | == DB based Messaging (end) --> | <!--JMS based Messaging (begin) == | <service name="message"> | <factory><bean class="org.jbpm.msg.jms.JmsMessageServiceFactoryImpl"> | <field name="connectionFactoryJndiName"><string value="java:/XAConnectionFactory"/></field> | <field name="destinationJndiName"><string value="queue/JbpmJobQueue"/></field> | </bean></factory> | </service> | == JMS based Messaging (end) --> | ... | </jbpm-context> | </jbpm-configuration> | Now, how should we control what configuration to use? Could it be made using a property or something so? The examples I've found are uncommenting sections in an unconditional fashion. I think that this case is a little different, as we want to choose between two configuration modes. Perhaps having local configuration files (in some place like local.config=${user.home}/jbpm/config ) should be simpler, and we could just try to use those files if they exist? Regards.
