Class reload for split directory structure

Question

I have tried to use the split directory structure in WL 8.1. I have a enterprise
application with 2 EJB modules and 2 WEB modules. I have tried to change one session
bean by just adding a logging statement and then use wlcompile to compile it.
Do I necessary call wldeploy to redeploy it? Or, will WebLogic automatically reload
the class file? Calling redeploy is so slow to me (about 3 minutes). Thus I want
to check if WL can just reload the class automatically.

Or, will WebLogic automatically reload the class file? No, by default it load the EJB in the application classloader, and
everytning in the classloader must change for it to be visible.

In your weblogic-ejb-jar.xml, you need to set
<enable-bean-class-redeploy>True</enable-bean-class-redeploy>
This tells WLS to load the bean impl class in a sub classloader
then in weblogic.Deployer you have to specify the bean class that changed.
weblogic.Deployer -name myapp -redeploy myEJB/com/foo/MyEJB.class
That works as long as you only make changes to the bean class itself.
