Re: RollingFileAppender vs CompositeRollingAppender

Fri, 05 Oct 2012 15:47:31 -0700

can you put a Class.forName("org.apache.log4j.CompositeRollingAppender") before any logging starts maybe a test app with main with the same classpath
maybe the log4j jar is sealed (manifest entry http://docs.oracle.com/javase/tutorial/deployment/jar/sealman.html )

Hi Tim,

Thanks for your response. I already have both the CompositeFileAppender
class file in the classpath, and the log4j.jar (which has
RollingFileAppender class) in the classpath. But only the log4j.jar class
is getting loaded, but not the CompositeFileAppender class.

Regards,
Praveen

Hi,

In our project we are using both RollingFileAppender and
CompositeFileAppender. Both these class files are loaded into classpath,
but only RollingFileAppender is being detected. And, for
CompositeRollingAppender I'm getting ClassNotFound exception. Since both
these classes extent FileAppender class, is this related to some

hierarchy

(parent/child) issue, where only high level class gets picked up? The
detailed log is given below, any thoughts? Appreciate your help.


There's no subtle trick here.  CompositeRollingAppender is not bundled
in the distribution jar.  You would need to compile the source and put
it somewhere in the classpath or in a jar in the classpath.
