My comments are based on jboss as of about 2 years ago.  JBoss 4 with  
jsr-88 deployment may possibly work differently and be more amenable to  
what you want.
What you want may be difficult to arrange.  JBoss undeploys everything  
on shutdown, and redeploys it automatically by scanning the hot-deploy  
directories on startup.  If you leave the portlets "deployed" on  
shutdown, what will happen when the portlet application gets redeployed  
on startup?  How will you determine if differences between the  
persisted state of the portlets is due to things like customization or  
due to changing the portlet application itself?
