Description

The code quoted here from CoreContainer.java ends up looking for a class named Log4j instead of Log4jWatcher. Neither name exists in the tree.

// Now load the framework
if(fname!=null) {
if("JUL".equalsIgnoreCase(fname))

{ logging = new JulWatcher(slf4jImpl); }

// else if( "Log4j".equals(fname) )

{ // logging = new Log4jWatcher(slf4jImpl); // }

else {
try

{ logging = loader.newInstance(fname, LogWatcher.class); }

catch (Throwable e)

{ log.warn("Unable to load LogWatcher", e); }

}
