If you need requests to take 2-3 days, then HTTP is not the protocol
for you. Are you accepting batch requests via HTTP and then working on
them after the request/response has completed? That would make more sense.
In any case, most logging frameworks create "Log" (or Logger) objects
that live for a long time: they aren't set up to create a Log/Logger,
use it for a bit and then discard it, since loggers tend to get used
for the life of the JVM.
I think what you want is a simple FileWriter. You can even use the
existing logging framework's log-level-checks if you want, like this:
PrintWriter out = null;
try {
if(logger.isDebugEnabled())
= new PrintWriter(FileWriter("/logs/job-" + jobId));
...
if(null != out)
out.println("Got an interesting value: " + interestingValue);
...
} finally {
if(null != out)
try { out.close(); }
catch (IOException ioe) {
logger.error("Couldn't close job log", ioe);
}
}
