Hi, Actually, that message: "No appenders..." means that what you're missing is not Log4J itself, but the configuration for it -- typically a file called either "log4j.properties" or "log4j2.xml". If you're not interested in seeing the log output of the program, you can just ignore the messages. Otherwise, you can try putting the following into a file called "log4j.properties" and add the directory it's in to the classpath (the -cp option you're already specifying): log4j.rootLogger=WARN, stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout The above will cause the messages to appear on stdout.

Hi,
I have a test install of Leap 42.1, where I try to run a certain java application and get this error instead:
cer@Gestor:~/Moria/Gigaset/cridmanager> java -cp cridmanager-1.4.3.jar net.sourceforge.cridremote.RemoteControlView log4j:WARN No appenders could be found for logger (net.sourceforge.cridmanager.Settings). log4j:WARN Please initialize the log4j system properly. cer@Gestor:~/Moria/Gigaset/cridmanager>
(I try to search for a package with "log4j" in the name, but https://software.opensuse.org/ seems down)
Normally, what I do is install the SUN java package instead of openjdk. I'm trying to avoid that in this system. I don't know if this is some missing package, or it is an incompatibility on the application I try to run.
