Log4J problem in exportated JAR in WSAD 5.1.2

[Etienne]

Hi,

I have a strange problem. I am doing a small librairie for another
projet. I have made a JAR using WSAD 5.1.2. When the other projet try
to use the JAR it trows this exception:

org.apache.commons.logging.LogConfigurationException:
java.lang.NoSuchFieldError: org.apache.log4j.Category: field level not
found (Caused by java.lang.NoSuchFieldError:
org.apache.log4j.Category: field level not found)

Any idea?

Thanks.

Looks like the version of Log4J that you are compiling against is not the
same version that you are running with. Check your classpath settings for
both projects.
