Re: Logging from shared components

[Timothy Bennett]

Ok... fair enough... I'll wait for a future version then...

In the meantime, if I log all servlets to the same log, is there a way I
could write the events from each servlet so that I could filter the log when
I view it to only see events from one specific servlet?

 You can't do this in log4j 1.2 but in future versions.

 Hi all...
 
 I'm a newbie to this list, so apologies up front if this question has
been
 asked and answered before.  Here's a logging scenario that I'd like to
 configure, but can't seem to find the magic to do so.  Hoping some of you
 here might help...
 
 Let's say I have Servlet A and Servlet B deployed in some servlet
container.
 Each servlet's init() method configures log4j and appends a
 RollingFileAppender with its own unique filename.  The desire here is
that
 each servlet is a separate application and therefore has its own trace
 logfile.
 
 Now, let's say we've got some jar file that has a class named Foo.  Foo
has
 a method called doSomething().  The class might look something like...
 
 public class Foo {
  private static Logger logger = Logger.getInstance(my.foo);
 
  public void doSomething() {
  logger.debug(You've invoked me!);
  }
 }
 
 
 Now, let's say that each servlet's doPost() method creates an instance of
 Foo and invokes it's doSomething() method.  What I find happening is that
a
 POST to either servlet results in debug log event thrown from the shared
 component being written to both servlet's log file.
 
 How can I configure log4j so that logging events in the shared component
 resulting from a POSTs to Servlet A are only written to Servlet A's log
 file, and logging events in the shared component resulting from a POSTs
to
 Servlet B are only written to Servlet B's log file?
 
 Thanks for the help...
