I am using UUID Random number as a primary key of Object when i save object in Database. So this generated UUID number should be unique. This way i got random number.
final String UUIDUserToken = UUID.randomUUID().toString(). Can this generated number unique for any generated number?

Give me idea.

I have done it like this way .
12 0/5 0-12,14-23 * * ?.
Its seem work fine.

Thanks for answer...

I am developing java application and in this i wanted to run some method periodically. I have used java schedule to run that method periodically. This is my Cron Expression.

public static String CRON_TIME = "12 0/5 * * * ?"; /*runs in twelth second by every 5 minutes*/ .
This works fine. Now I wanted to stop running this scheduler for one hour per day. How I can write Cron Expression to do it? Give me a idea.

Thanks in advance

Thanks Mahesh. Your idea was very helpful for me... Thanks again....

I have put log4j.properties file in class path. then Load using following code. Now Log4j Logger is working.
ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); PropertyConfigurator.configure(classLoader.getResource("log4j.properties"));

After i add following code example, log file created when jar file run with command prompt.

PropertyConfigurator.configure("C:\\eclipeworkspace\\Log4jTest\\log4j.properties");

How I can give relative path instead of exact path ?

This is my Student class that used to test log4j.

public class Student{ private static final Logger logger = Logger.getLogger(Student.class.getName()); public Student() { PropertyConfigurator.configure("log4j.properties"); } public static void main(String args[]){ logger.log(Level.INFO, "My log4j Test"); } }

This is my log4j.properties file

# Set root logger level to DEBUG and its only appender to Appender1. log4j.rootLogger=INFO,Appender1,Appender2 # Appender1 is set to be a ConsoleAppender. log4j.appender.Appender1=org.apache.log4j.ConsoleAppender log4j.appender.Appender2=org.apache.log4j.RollingFileAppender log4j.appender.Appender2.File=C:/Log4j/MyLogExample.log # Appender2 uses PatternLayout. log4j.appender.Appender1.layout=org.apache.log4j.PatternLayout log4j.appender.Appender1.Target=System.out log4j.appender.Appender1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n log4j.appender.Appender2.layout=org.apache.log4j.PatternLayout log4j.appender.Appender2.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n log4j.appender.Appender2.MaxFileSize=50KB # Keep 10 backup file log4j.appender.Appender2.MaxBackupIndex=10


when i run using eclipes MyLogExample.log file created. then after i created jar file and run using command prompt. but when i run jar file log file is not created.

in console i can see this error.

log4j:ERROR Could not read configuration file [log4j.properties].
java.io.FileNotFoundException: log4j.properties (The system cannot find the file specified)

Give me idea why is this log file is not create with jar file.

Thanks in Advance...

I am developing jasper report. So i have created abc.jasper file by using iReport. Then i have put it into /WEB-INF/reports/ . Then I have loaded abc.jasper file as below. but it doesn't work.
FileInputStream file = new FileInputStream([b]RELATIVE_PATH[/b]); System.out.println("loading report.. file read "+file.available()); JasperReport jasperReport = (JasperReport) JRLoader.loadObject(file);

if I put Exact path intesed of Relative path above code is working fine. So Can any one suggest me how to load abc.jasper file by giving relative path?

Thanks in advance
