I'm trying to use the following pattern to recover my ejb's after a
failover:
Each EJB checks the need for recovery inside "ejbActivate()".
If there is a need to recover, it eventually calls another EJB to get some
value.
I'm facing a deadlock situation here where I believe that it should appear a
"concurrent calls on stateful beans" exception instead:
EJB1 activates. He needs to recover and needs to call ejb2 to have a certain
value.
EJB2 is passivated so EJB2 activates. He also needs to recover and needs a
value that is in ejb1.
I find a deadlock occuring here, where I was expecting to obtain an
exception ("concurrent calls on stateful beans").
Using this pattern with methods other than ejbActivate we get that
exception, so shouldn't it occur here aswell?
ejb1 {
ejbActivate() {
ejb2.someMethod()
}
}
ejb2 {
ejbActivate() {
ejb1.someMethod()
}
}
