Hi,
when calling a Bean (CMP) and passing a reference to itself, a call to a
property getter results in an endless loop in the transaction interceptor.
See the following:
Client calls:
bean.changeMyOrt (bean);
Beans method is:
public void changeMyOrt (MyBean l) throws RemoteException
{
System.out.println ("Setting Ort: " + ort);
System.out.println ("to new Ort: " + l.getOrt ());
setOrt (l.getOrt ());
System.out.println ("Setting Ort..done: " + ort);
}
The server loops endless wihtin this thread:

It seems to be the line 133 in TxInterceptorCMT.invokeNext that causes the
loop. There, the subsequent call to the bean is done in remote mode. Is this
nessesary? Or is something wrong with my code?
Thanks for help!
Lutz.
