[jboss-jira] [JBoss JIRA] Resolved: (JBAS-8541) Deploying an application that has its own slf4j jars causes errors in the server log

David Lloyd resolved JBAS-8541.
-------------------------------
Fix Version/s: 7.0.0.M1
Resolution: Done
You missed the simple solution of upgrading slf4j in the AS. Otherwise, these are the
only solutions that are going to happen for 5.x/6.x. There is no other magical fix
possible.
For AS 7.x, the class loading model will be modular, not flat, meaning that you can easily
selectively include or exclude provided modules like slf4j.
If it makes you feel better, I'm marking this issue as "fixed for 7.0.0.M1".
Otherwise you must use one of the existing solutions. If custom class loading isn't
working then you should open a separate issue for that because that would be a bug that
can and should be fixed within the 5.x/6.x series.

Key: JBAS-8541
URL: https://jira.jboss.org/browse/JBAS-8541
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Logging
Affects Versions: JBossAS-5.1.0.GA
Reporter: Nikita D
Assignee: David Lloyd
Priority: Minor
Fix For: 7.0.0.M1
If an application depends on a different version of slf4j than the one packaged with
JBoss, the slf4j jars (api and impl) need to be included with the application. This
results in the "multiple SLF4J bindings" error message:
00:34:25,247 ERROR [STDERR] SLF4J: Class path contains multiple SLF4J bindings.
00:34:25,247 ERROR [STDERR] SLF4J: Found binding in
[vfszip:/C:/a/bin/jboss/jboss-5.1.0.GA/common/lib/slf4j-jboss-logging.jar/org/slf4j/impl/StaticLoggerBinder.class]
00:34:25,247 ERROR [STDERR] SLF4J: Found binding in
[vfszip:/c:/a/ear/suite.ear/lib/slf4j-log4j12-1.5.8.jar/org/slf4j/impl/StaticLoggerBinder.class]
00:34:25,247 ERROR [STDERR] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings
for an explanation.
