I'm pretty sure. I just found this in section 10.5.1 of the spec (about a bean's lifecycle):
The instance does not move to the ready state during the execution of a finder or a home method. An ejbSelect<METHOD>(...) method may be called by an entity bean's home method while the instance is in the pooled state. Also the O'Reilly EJB book has a section on calling ejbSelect methods from Home methods. Anyway I really appreciate you taking a look at it.
