Why EAP 6.2 console log can not print System.out.println statements?

Issue

• JBoss EAP 6.2 in console log can not print SOP (System.out.println) statements.
• In production server Jboss 6.2 log can not be print in console. Why class file log not print in JBoss 6.2 in console.
• In JBoss EAP 5.1 we have not configured logger file only SOP (System.out.println) statements in class file they are printed in "server.log" file. Now we have deployed the same application on JBoss EAP 6.2 in this version jsp file SOP (System.out.println) are printed in "server.log" but when we give SOP (System.out.println) in class file they are not printed in "server.log" file. So how it is printed in "server.log" file.
