Appear to get the following two errors while doing hot-deploy.

1.
09:26:50,859 INFO [MainDeployer] could not delete directory file:/D:/EMS/jboss/
jboss-3.0.4_tomcat-4.1.12/server/default/tmp/deploy/server/default/deploy/hotdeploy.jar/88.hotdeploy.jar restart will delete it

2.

How bad is 1 ? What is 2, and how can it be avoided ? One additional question, how does hot deploy handle ordinary jars (non-EJB) ? So non-EJB jars get added to the class path and classes reloaded ?

Thanks in advance.
