Optional Packages
domain-dir/lib/ext is a java.ext.dirs directory and is the location for installing optional packages.
Global Sharing
Place libraries in domain-dir/lib and domain-dir/lib/classes to add
libraries to the common classloader. This is commonly used for
libraries like JDBC drivers that used by multiple applications.
Requires an AS restart.
i would
cp log4j*.jar to /domain-dir/lib/ext FIRST
and if not log4j still CNFE
cp log4j*.jar domain-dir/lib
//our of curiosity how are you instantantiating the Log4j classes?
import org.apache.log4j.Category;
import org.apache.log4j.PropertyConfigurator;
static final Category log = Category.getInstance(YouClassName.class);
static final String LOG_PROPERTIES_FILE = "log4J.properties"; //PUT THIS at WEB-INF/classes
//i use this standard log4j initialiser
private void initializeLogger()
{
logProperties = new java.util.Properties();
try
{
logProperties.load(new java.io.FileInputStream(LOG_PROPERTIES_FILE));
org.apache.log4j.PropertyConfigurator.configure(logProperties);
log.info("Logging initialized.");
}
catch(java.io.IOException e)
{
System.err.println("Unable to load logging property " + LOG_PROPERTIES_FILE);
}
}
let me know if you need any help with this..
