Problem Using Log4J and Commons Logging with Struts
Using the latest nightly build from 2002-12-27, the latest
Commons Logging nightly build from 2002-12-27, and Log4J
1.2.7...
I have Common Logging configured to use the SimpleLog, and
everything is working fine, with both my application and
Struts successfully logging to the simple log.
When I just drop log4j-1.2.7.jar into WEB-INF/lib,
regardless of whether I configure Commons Logging to use
the Log4JCategoryLog or not, I get this exception:
java.lang.NoClassDefFoundError: org/apache/log4j/Layout
at org.apache.commons.logging.impl.Log4jFactory.getInstance(Log4jFactory.java:140)
at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:255)
at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:390)
at org.apache.struts.action.ActionServlet.<clinit>(ActionServlet.java:372)
[...]
I've been trying to follow the set up shown in Cavaness'
Programming Jakarta Struts book, chapter 15. What am I
doing wrong?
Thanks,
Paul

I've added this to my CATALINAOPTS:
-Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
and have both working side by side quite well. Read the commons-logging
docs for other ways to initialize it.
HTH,
Andreas.
<offtopic-SCNR-remark>
In the HOLIDAY thread somebody said the reference "eye of the needle" by
Jesus is/was a gate or door and the point is humility. I have a
different take here based on the context: His disciples asked immediatly
after that "Then who can enter??" This sounds very much like disbelief,
like "then nobody can get in". Jesus answered sth like "It's impossible
for man, but nothing is impossible for God." To me this supports the
interpretation that "eye-of-needle" means a real small-thingie needle,
and the point here is grace primarily.

Add two files to your WEB-INF/classes directory:
commons-logging.properties <==============================
org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Lo
g4jFactory
log4j.properties <=======================================
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG,A1
# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
That should fix things, I believe. The commons-logging package is going
to expect that you want to use Log4J if you have the Log4J JAR in the
classpath (ie your WEB-INF/lib directory). It's not going to "work"
correctly until you configure it properly though (at least, it never has
for me).
Good Luck!
