Hot re - deploy of ejb jar fails on JBoss 4.2.2 GA with the error: C:\Programme\eclipse-jee-ganymede-win32\eclipse\plugins\org.eclipse.jst.server.generic.jboss_1.5.205.v200805140145\buildfiles\jboss323.xml:23: Unable to remove existing file C:\KW_SERVER\server\default\deploy\MY_EJBs.jar When I try to delete the MY-EJBs.jar manually, it only works when I stopped JBoss server before. Seems that jboss server itself holds a lock on the file?! According to http://www.jboss.com/index.html?module=bb&op=viewtopic&t=135599 this is a problem with jboss server 5.x.. May it also be a problem with jboss server 4.2.2 or should hot redeployment work in general with this version?
