Hi
I believe there is a bug when deploying exploded WAR project using JBoss 4.x app server connector.
What occurs (especially on LARGE projects) is that JBoss starts deploying <project>.war folder before MyEclipseIDE is finished copying contents into it.
Due this mis-synchronization a project will fail to deploy on JBoss because not all classes, libraries and other resources are done copying when deployment occurs.
WORKAROUND:
Defaul deployment scanning interval in JBoss is 5000 mils (5 seconds)…This can be increased in conf/jboss-service.xml. This seem to help but occasionally problem still occurs.
PROPOSED FIX:
Have ME use tmp folder on initial deployment (with the name that JBoss ignores) and then rename it to <context>.war to avoid issues with large projects.
