Restructure way jbossas modules are created ------------------------------------------- Key: BAM-122 URL: https://issues.jboss.org/browse/BAM-122 Project: Business Activity Monitoring Issue Type: Feature Request Reporter: Gary Brown Assignee: Gary Brown Fix For: 1.0.0.M5 Use a similar approach to switchyard to build the modules, and allow external modules (e.g. drools, mvel) where they don't already exist. So only overwrite the external modules if not already present.
