That works for me, 3 of the 4 are mine and the other is Jim's so
it's kind of a Novell endeavor, but I'm sure he'll down with that
also so let's go for it.

Is everyone in agreement with moving to Apache Commons Logging?
If so - I can create the ticket and get it schedule for an upcoming
milestone release (say 1.1 M3). The specific work here would be to
just change the following four components to use commons logging
from log4j?
org.eclipse.higgins.idas.cp.jndi
org.eclipse.higgins.idas.spi
org.eclipse.higgins.util.idas.cp
org.eclipse.higgins.util.jscript

Yes, using Apache Commons Logging makes sense.

Yeah. That's why the best choice would probably be for all Higgins
components to use Apache Commons Logging.
Most of them do that anyway. But some use log4j directly, and as
Prakash points out that's not optimal. They should probably be
changed to Apache Commons Logging too.
These seem to use log4j directly:
org.eclipse.higgins.idas.cp.jndi
org.eclipse.higgins.idas.spi
org.eclipse.higgins.util.idas.cp
org.eclipse.higgins.util.jscript

Apache Commons Logging and SLF4J are conceptually the same thing
(thin layer over various logging frameworks), but it seems that
SLF4J is better for some reasons.
In any case, Prakash is right. Some Higgins projects are using log4j
directly and therefore don't allow people a choice of logging
frameworks.

SLF4J (http://www.slf4j.org/) already implements a logging facade that
Higgins can use that can abstract JSR47, log4j or logback logging. Its
using a permisive MIT license.
Just a suggestion.

Prakash,
Assuming for the moment that Higgins folks agree with swapping JSR47
for
Log4J, are willing to work on and contribute a patch along these
lines?

Subject: [higgins- dev] Log4J vs JSR47 loggers in Higgins' IdAS code
Hi All,
I found that higgins' IdAS uses log4j for lgging . As IdAS
APIs
consumer will be from different organizations, they will have their
only
guide lines for selecting a logging framework , this sort of direct
usage
of logging calls from Log4J will have the following limitations.
1. Say an existing software uses JSR47 logging framework and they
plan
to use IdAS API in one of their component. They will niether
prefer
to maintain two logging frameworks simultaneously to use IdAS API
nor will they will prefer to move to log4j if they plan to use
IdAS
API. Admining two logging mechanism in one software will be not a
good idea and also if the software is having a large code base ,
its
not possible to move from one existing logging frame work to
Log4J.
2. Loggers as choosen based on performance, internationalization
flexibility , better features and so on , but this way the user
will
have no choice but stick to log4j even if its a good logging
toolkit.
3. Many roganizations will have their own logging framework or they
will
have some standard to use a specific logging framework . So using
IdAS API based on Log4J may not be possible for them.
Similarly there can be many such limitation which needs to be
identified.
To over come such issues, Is it possible to implement logging using
one of
the following ways or any other ways which can help in avoiding such
issues
mentioned above.
1. Replace Log4J with JSR47 (preferrable as in many areas JSR47
is the
preferred logger compared to Log4J)
2. Write a wrapper logging framework which can be either configured
for
Log4J and JSR47
Thanks and Regards,
Prakash
