Subject [jira] [Commented] (LOG4J2-365) ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogge
Date Wed, 21 Aug 2013 08:30:52 GMT

wei wang commented on LOG4J2-365:

Hi Remko,

Now I come to the basic things you have mentioned from the very beginning!  The -cp should
not have any space after ";"  after remove the space it works !!! Sorry :)

I will continue to look into how to deal with the lib\log4j-*.jar could be delivered with
my child.jar(otherwise the user will have to download log4j2 package them by themselves).

I used ant to build the jar however, it is not allowed to have serveral META-INF built so
I have to excludes=META-INF/**/* in the ant build which cause the problem for log4j to read
the properties file in the lib.

I have unpacked the lib\log4j-*.jar and repack them again with the child.class. No compile
error but missing log4j.properties in META-INFO ? (I did not know it is needed).

<zipfileset src="lib\log4j-core-2.0-beta7.jar" includes="**/*.class excludes="META-INFO/**/*"
<zipfileset src="lib\log4j-api-2.0-beta7.jar" includes="**/*.class excludes="META-INFO/**/*"
