How to save log output in a file in linux

I need to create an accessible log file in our linux server. A java program is used to create a log.

In my console

Sep 11, 2014 3:03:05 PM com.gsis.bom.Log appLog
SEVERE: test 1
Sep 11, 2014 3:03:06 PM com.gsis.bom.Log appLog
INFO: test 2
Sep 11, 2014 3:03:06 PM com.gsis.bom.Log appLog
INFO: test 3

But this messages should be saved in a file in linux. For e.g. /home/logs How can I do it?

THANK YOU

EDIT

LogManager lm = LogManager.getLogManager();
          Logger logger;
          FileHandler fh = new FileHandler("log_test.txt");

          logger = Logger.getLogger("LoggingExample1");

          lm.addLogger(logger);
          logger.setLevel(Level.INFO);
          fh.setFormatter(new XMLFormatter());

          logger.addHandler(fh);
          logger.log(Level.SEVERE, "test 1");
          logger.log(Level.INFO, "test 2");
          logger.log(Level.INFO, "test 3");
          fh.close();

This is the code that I am using. Ok I can see it in my console. But I need the messages to be saved in a file. For example at /home/logs/log.txt in our linux server

Seems that you are using . In that case, you can add an appender programmatically as in the following example. 

// the maximum number of bytes to write to any one file
int limit = 5 * 1024 * 1024; 

// the number of files to use
int count = 10;              

Handler handler = new FileHandler("/home/logs/log_test.txt", limit, count);
Logger.getLogger("").addHandler(handler);

You may want to see Where does java.util.logging.Logger store their log, Java logging opening "too many" logfiles and Java Logging API generating empty log files

You can use class something like below,

import org.apache.log4j.Logger;

public class CreateLog{

    static Logger logEntry = Logger.getLogger(
                  CreateLog.class.getName());

    public void testLog(){
        logEntry.info("some information message");
        logEntry .error("some error message");
    }
}
