A quick test: put commons-logging.jar and log4j.jar in common/lib.please help me understand if there's anything out-of-the ordinary that I need to do to run tomcat with delegation and a simple class loader hierarchy. I quickly reviewed the class loader HOW-TO and nothing popped out as how to do this.
Most classloader problems are due to the loader hierarchy.
It is possible ( at least with 5.0 - I'm running it this way ) to
put all the jars in the same place ( like common/lib or just in CLASSPATH)
and run tomcat with delegation and a simple class loader hierarchy.
If you mean putting everything -- all the jar files mentioned in that document into $CATALINA_HOME/common/lib...
I would bet the same works with 4.1.x - jboss for example is using
embeded tocmat with all the jars in the main loader.
Regarding the unix channel - you need to be able to load libjkjni.so and libapr.so. It may be a good idea ( at least for testing ) to place
them in the JRE_HOME/lib dir - that's a place where java will certainly
look for .so files. ( at least with JDK1.4 I had some problems with loading
jars, and the LD_LIBRARY_PATH may create some problems ).

Yes -- *I* get this error on 4.1.12/5.0 on Solaris 8, hopefully Robert
Williams can provide details about his specfic config:
I have:
j2sdk1.4.1
commons-logging-1.0.2
jakarta-log4j-1.2.6
Tried this against:
jakarta-tomcat-4.1.12
jakarta-tomcat-4.1.12-LE-jdk14
jakarta-tomcat-5
I get the same error -- can't create apr...
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at org.apache.jk.apr.AprImpl.<clinit>(AprImpl.java:340)
: The problem seems releated to class loading ( as usual :-).
Yeah, but how do we work-around it or solve it permanently. I've tried
massaging the catalina.sh startup script to include commons-logging.jar in
CLASSPATH that gets passed to the JVM at startup.
I've put commons-logging.jar in $CATALINA_HOME/server/lib even though
commons-logging-api.jar exists there.
I see in the -LE-jdk14 that there's a log4j.rename-to-jar. What's the
confidence level that this will resolve this problem?
Is this a problem on other platforms?
Is this NOT a problem on Linux?
