Debugging java expressions in RPAS - logging messages

Hi,

We are trying to use a java expression in the RPAS - MFP calc rule group. We need to log messages from the java code when it gets executed through a calc rule. We tried the following ways of logging messages in the code:

1. System.out.print

2. Methods of Logger class

With both these ways, we are unable to find out to which location / file these messages are logged? Tried to check in the RPAS daemon log without success. Please advise.

Thanks in advance!
