I have some simple bean:KeyEntityBean and EnvironmentSessionBean. The SesseionBean use local interface to visite KeyEntityBean to get somekey's next value.This is some code in SessionBean:
home =(KeyEntityLocalHome) context.lookup("java:comp/env/KeyEntityBean")
key = home.findByPrimaryKey(keyStr);
keyValue = key.getNextId();
After compiling,package and deploy,When I test whith a simple client,the jboss throw ClassCastException.And When I shutdown and reRun the jboss,the client and bean worked well.Why?
