To solve this problem. You have to do two things: 1. mark the DAO as transactional or function which is doing database call like:   @Transactional    public class EmployeeDaoImpl  extends DaoImpl implements EmployeeDao{  ///// }            OR @Transactional     public long addEmployee(Employee employee) {         System.out.println("Employee:"+employee );         long id = employeeDao.addEmployee(employee);         System.out.println("Id1: " );         return id;     } 2. Enable the annotation driven transcation management in applicationContext.xml (where your beans are defined): <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="ht...

Do you want to know which all files are in the jar without extracting it.? This is a small tutorial where I am listing all the xml files. import java.io.IOException; import java.util.ArrayList; import java.util.Enumeration; import java.util.List; import java.util.jar.JarEntry; import java.util.jar.JarFile; /**  * List the name of all xml which is in given jars  *  * @author abdul  */ public class ListXmlFiles {     /* Stores the xml file name*/     List<String> list = new ArrayList<String>();     public List<String> getList() {         return list;     }     /**      * @param args      * @throws IOException      */     public static void main(String[] args) throws IOException {         ListXmlFiles xmlFiles = new ListXmlFiles();  ...

1. Send a Command’s Output to the Clipboard Note: This will work for any command. Without doing copy and paste the output, We can send the output directly to the clipboard. ipconfig | clip 2. Open Command Prompt From a Folder Do you want to open the command promp within a folder from explorer ? All you have to do is hold shift while right  clicking on a folder and the option will appear in the context menu. 3. Command History We can view our past command  i,e using doskey command. doskey /history 4. Drag and Drop Files to Change the Current Path Another neat trick if you are not a fan of opening a command prompt from the context menu is the ability to drag and drop folders onto the prompt and have it automatically enter the path of the folder. 5. Run Multiple Commands In One Go Want to run multiple command at once?  You can do this by linking them with double ampersands. ipconfig && netstat

Suppose You have to access some properties (from a file), which are already defined in my build file. To be able to access the properties We can use the build attribute of the property task.  build.properties #Release information #Thu Oct 14 16:25:12 CEST 2004 build.number=115 release.version=0.4 release.name=framework   Ant Example Target <target name="read.properties"> <!-- Read the properties from the release of the framework --> <property file="build.properties" prefix="build"/> <echo message="${build.build.number}"/> <echo message="${build.release.version}"/> <echo message="${build.release.name}"/> </target>    Output Buildfile: C:\build.xml read.properties: [echo] 115 [echo] 0.4 [echo] framework BUILD SUCCESSFUL Total time: 3 seconds

chkconfig command is used to setup, view, or change services that are configured to start automatically during the system startup. chkconfig has five distinct functions: adding new services for management, removing services from management, listing the current startup information for services, changing the startup information for services, and checking the startup state of a particular service. chkconfig --list [ name ] chkconfig --add name chkconfig --del name chkconfig [ --level levels ] name < on | off | reset > chkconfig [ --level levels ] name   OPTIONS --level levels Specifies the run levels an operation should pertain to. It is given as a string of numbers from 0 to 7. For example, --level 35 specifies runlevels 3 and 5. --add name This option adds a new service for management by chkconfig . --del name The service is removed from chkconfig management. --list name This option lists all of the services which chkconfig...
