i've done some trial:.
an action
@InjectEJB(name = "WAP-Shop/TestDeiBeanBean")
TestDeiBeanLocal tdb;
public String execute() throws Exception {
// scb = lookupShopCartBean();
System.out.println("value --> " + tdb.value());
System.out.println("setTrue " + tdb.setTrue());
...}
the ejb
private boolean b = false;
public boolean value() {
return b;
}
public boolean setTrue() {
b = true;
return b;
}
public boolean setFalse() {
b = false;
return b;
}
the output is:
21:27:46,062 INFO [STDOUT] value --> false
21:27:46,078 INFO [STDOUT] setTrue true
--lose data--
21:27:47,578 INFO [STDOUT] value --> false
