Access logger in different class

Question

I have created a logger in my main class as:

public static Logger logger = Logger.getLogger( MainClass.class.getName());

I declared it public static.

this is log4j.properties:

Root logger option

log4j.rootLogger=INFO, file

Direct log messages to a log file

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=D:\\loging.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Now i want to access this logger object in different class. When i tried giving logger directly it is giving error though i made it public static.

Below is my class from which i am trying to access logger object:

public class Db_Connector 
{
     MainClass.logger <------error
     //create ResultSet Class Object
     public ResultSet GetDataFromDB(){

        ResultSet resultset = null;
         try {  

                DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());   
                System.out.println("Connecting to the database...");   
                Connection connection = DriverManager.getConnection(
                        "jdbc:oracle:thin:@host:1521:Db", "User","pass01");
                Statement statement = connection.createStatement();   
                resultset = statement.executeQuery("select * from employee"); 

            } 
         catch (Exception e) {   
                System.out.println("The exception raised is:" + e);   
                            } 

         return resultset;
        }   
}

Answer 1

You should create public static variable in your DB_Connector class and assign MainClass.logger to it.

Answer 2

Make sure that the Class that wraps up your Logger is also public
