I encountered the following error when deploying my EAR application.
Dec 8, 2011 4:24:19 PM RMICClassLoader runCompile
SEVERE: log4j:ERROR A "org.apache.log4j.xml.DOMConfigurator" object is not assignable to a "org.apache.log4j.spi.Configurator" variable.
log4j:ERROR The class "org.apache.log4j.spi.Configurator" was loaded by
log4j:ERROR [com.ibm.tools.rmic.iiop.DirectoryLoader@495e495e] whereas object of type
log4j:ERROR "org.apache.log4j.xml.DOMConfigurator" was loaded by [java.net.URLClassLoader@4a804a80].
log4j:ERROR Could not instantiate configurator [org.apache.log4j.xml.DOMConfigurator].
I only have 1 log4j.jar in my library and log4j.xml properties.
if I remove the "properties" from META-INF classpath, the error is solved, but by doing this, the application will not be able to find the log4j.xml file.
