You are correct in the the stdout/stderr data will only be returned when
the command has completed.
In addition to the STDERRTOSTDOUT and RETURNSTDOUT options, you can
specify the STDOUT <filename> option, specifying a fully-qualified name
where the stdout/stderr file should be written on the remote machine where
your command is running (otherwise STAF will create a temporary file for
you). Then, while the command is running on the remote machine, you could
use another tool (such as "tail" if on Unix) to view the content of the
stdout/stderr file while the command is still running.

Subject: Re: [staf-users] Question about the STAF log
Hi Sharon:
Thank you for the quick reply. I noticed the "STDERRTOSTDOUT" and tried
it. Please correct me if I am wrong. For the I found STDERRTOSTDOUT, I
can only get this output after my remote test func finished. But here, I
am hoping I can catch the output info during its running. For example,
when we run our java program, the log4j could log message at any steps of
the program running. So, is it possible for me to log information in the
STDERRTOSTDOUT during remote func running.
Thanks a lot
Tun

So, via your Java program, I assume you are submitting a START request to
the STAF PROCESS service to run your test function command on a remote
server. When your test function runs, it writes output to stdout/stderr
(what you see on the screen when you run it manually). The STAF PROCESS
service allows you to redirect stdout/stderr to a file and to return this
information in the result (so that you can then do whatever you want with
this information, e.g. print it).
For example, the following PROCESS START request runs a command that
writes output to stdout/stderr, waits for it to complete, and returns the
command's stdout/stderr data in the result.
C:\>STAF local PROCESS START SHELL COMMAND "java -version" RETURNSTDOUT
STDERRTOSTDOUT WAIT

}
For an example of Java code that submits a similar STAF PROCESS START
request with the RETURNSTDOUT STDERRTOSTDOUT options and then accesses the
return code and the stdout/stderr data, see example 4 in section "3.1.1
Class STAFHandle" in the STAF Java User's Guide at
http://staf.sourceforge.net/current/STAFJava.htm#Header_STAFHandle.

Subject: [staf-users] Question about the STAF log
Hi:
I am new to STAF and I have a basic question about the STAF log.
Right now, by using Java, I can new a STAFHandle and give a request to
invoke my test function on a remote server. This part is fine.
Now I have a question about the log. Is there any way to new STAF log API
in java and catch all the information of what's happend on the remote
server? Let me explain more.
On my remote server, if I open a command-line prompt and run my test func,
there are lots of information printed line by line on the screen. But when
I invoke this test func through STAF, I can only see a black command-line
prompt opened and there is nothing printed during running. Of course, this
command-line windows disppear after the test func finsihed. So, here, I
want to catch those runtime information in my Java program. Is this
possible? (I do not want to launch another log viever to see those info. I
want to print the info in my java program)
Thank you very much for the help
Tun
