Executing sqlldr (sql loader) from java and returning the error code

Question

I'm wandering do sqlldr return any error code whenever it hit error while running in java.
For example, if i run in command prompt using the command below,
C:\ >sqlldr uid/pwd data=abc.dat control=abc.txt
It might give me some indicator that error occurs such as
SQL*Loader-601: For INSERT option, table must be empty. Error on table CURRENCY
or
SQL*Loader-500: Unable to open file (abc.txt)
SQL*Loader-553: file not found
SQL*Loader-509: System error: The system cannot find the file specified.
But when i run in java using the code below,
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("sqlldr uid/pwd data=abc.dat control=abc.txt");
int exitVal = proc.waitFor();
System.out.println("Process exitValue: " + exitVal);
it will only give me the same exitValue of 1(i presume its error) / 0 (i presume no error) instead of the details of the error.
How can i get the exact error code/message if i were to execute it using java?
Any solution?

mg,
I don't think user576271 wants the exit code, I think [s]he wants the error message.
But wouldn't error messages from SQL*Loader be sent to the stderr stream, and not the stdout stream?
In which case user576271 would need method "getErrorStream()" of class java.lang.Process, no?
Good Luck,
Avi.
