you can ignore this exception. The client closed its socket connection. In future versions this is just a trace/debug level exception. Sorry.
4.0.3.zip does not come with EJB3. You have to download the EJB3 distribution and install it yourself, or use the graphical installer.

I was just confused because in default/lib there is jar such as ejb3-persistence.jar. So I thought that ejb3 was included in 4.0.0 zip.
But with installer it works fine, that's not a problem.
