I have query regarding R & Rserve. In Rserve, there is a way to capture Errors by RSrvException class, but is there any way to capture warning messages?

   I have found that there is "warnings()" command in R, which lists the last warning message, but I am not able to get the warning message in java program by executing the following line:

REXP rx = null;
rx = connection.eval("x<-sqrt(-9)"); // will generate warning message connection.eval("warnings()").asString(); // this displays null instead of warning message

Please reply me correct way, if any, to display warning message.
