Is there any way in *"jboss-deployment-structure"* I can define how to load classes before deploying EAR? I also tried moving class definition from *my-custom-classes.jar* to *my-custom-ejb.jar* and loading class definition on to current thread, but this also didn't work. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/795816#795816] Start a new discussion in JBoss AS Development Deployment Framework at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
