hello all hello list

i am connecting from a httpservlet via jndi to an container-managed entity
bean and/or stateless session bean.
(httpservlet -> stateless-sessionbean -> cmp entity bean)
jndi lookup is ok and PortableRemoteObject.narrow(ref, some.class) works
too,

but home.create() works only if i did not redeploy the session bean!
after redeploying the session bean i get and exception.


if i use the same code and connect from an eg. session bean to an cmp entity
bean
and redeploy the cmp entity bean everything works fine!

any hints ?

cheers
lothar
