Regex matching tutorial

2012-02-01T02:00:00.001-08:00

A simple program that will match the text enclosed on quote:

package embed;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class RegexTestStrings {
public static void main(String args[]) {
Pattern pat = Pattern.compile("\"[^\"]+\"");
String line = "Block 1, Block 2, \"Street 3, Block 3, Unit 3\", Block 4, \"Block 5, Unit 5\"";
Matcher mat = pat.matcher(line);

while (mat.find()){
System.out.println("Match: " + mat.group());
}
}
}

OUTPUT:

Match: "Street 3, Block 3, Unit 3"

Match: "Block 5, Unit 5"

JSF Tutorial (I18N) Part 2

2012-01-28T21:08:00.000-08:00

JSF Internationalization

Based on our previous sample, we will now use the resourceBundle.

We add new files(*.properties and faces-config.xml) for our resource bundle

faces-config.xml
- Please pay special attention to the namespace, which uses the javaee, and the facesconfig, which is version 2.0
- On this configuration, we define the resourceBundle that can be use within the whole application.
- We define the default locale, and the variable to access the resourceBundle, which is the "msgs"

<?xml version="1.0" encoding="UTF-8"?>
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">

<application>
<locale-config>
<default-locale>en</default-locale>
</locale-config>
<resource-bundle>
<base-name>messages</base-name>
<var>msgs</var>
</resource-bundle>
</application>
</faces-config>

messages.properties

hello.world.name=Name
hello.world.header=This is a simple Hello World example
hello.world.enter.name=Please enter your name
hello.world.select.language=Please select language

hello.world.location.param=Location: {0}
hello.world.title.login.page=Login Page
hello.world.btn.press.me=Press me

helloWorld.xhtml
. . .
<h:outputLabel for="name" value="#{msgs['hello.world.enter.name']}" />
. . .


<h:outputFormat value="#{msgs['hello.world.location.param']}" >
<f:param value="Singapore"/>
</h:outputFormat>

Build the project, and restart the server

Getting Started on JSF Tutorial Part 1

Technologies:
- Glassfish3 server
- Maven 2
- Java 1.6.0_24
- IDE: eclipse

Folder Structure:

Notice that we have .jsp and .xhtml file

Below are the codes:
web.xml
- Please pay special attention to the declaration of namespace. The version of web-app is 2.5 and the xmlns namespace is javaee

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

HelloWorld.java
- A Managed Bean that holds the value for the property "name".
- Since we are using the JSF 2.0, we can use the annotation to specify the Managed Bean. This can be done by declaring @ManagedBean at the top of the class name

package com.lai;

import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

@ManagedBean
@SessionScoped
public class HelloWorld implements Serializable{
//properties
private String name;
/**
* default empty constructor
*/
public HelloWorld(){
}
//-------------------getter & setter
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
/**
* Method that is backed to a submit button of a form.
*/
public String send(){
//the welcomePage is the name of our .xhtml file. If we didnt specify the faces-config.xml, we can use
//the approach of specifying the .xhtml or .jsp page name
return "welcomePage";
}

public String sendJsp(){
//for jsp page
return "welcomePage2";
}
}

helloWorld.xhtml
- You can use the implicit navigation on the commandButton, by specifying the name of the jsp page, or you can call the HelloWorld class to do this:

HelloWorld.java
public void send(){
return "welcomePage";
}
OR
helloWorld.xhtml
<h:commandButton value="Press me" action="welcomePage"/>

My Wedding Song List

2012-01-16T08:07:00.000-08:00

Its just fun to list your favorite songs and hopefully to be able to play that on your big day. I just want to list so I will always remember

1. A thousand Years - Christina Perri
2. Flightless Bird - American Mouth
3. Marry You - Glee / Bruno Mars version mashup

Timeline Starts Now

2012-01-16T07:45:00.000-08:00

This day, January 16, 2012, I will monitor what I want to achieve
For this year, I want to achieve these things:

1. Complete my TODO study list
2. Lose weight, by diet and exercise daily
3. 3 certifications for this year
4. Be able to become part by part knowledgeable on stocks first (other investment on next year)
5. lovelife :p

I will start to log my daily progress for each day!

If I did accomplish something good for 6 months, I will reward myself :)
Hopefully, I will be ready for my 1st target certification by 3rd Week of April or 3rd Week of May

Currently, I'm prioritizing my todo list and losing weight :D

Random thought

2011-12-07T23:38:00.000-08:00

Its weird seeing your future with someone who doesn't show interest on you.
This is the first time it happens to me. I have crushes and BFs before, but I didn't see my future with them, that's why Its really weird.
Oh well, I hope he also thinks of me :D

In Time movie

2011-11-06T06:43:00.000-08:00

Having watch In Time movie of Justin Timberlake makes me realize that, what's in your mind cannot be taken away from you.
The movie has this plot of living literally thru time, embossed on their body. But this time, the time you have can be taken away from you, even if you are unaware / without your consent, like what happens for Amanda Seyfried.

So live your life to the fullest, and remember that Knowledge is POWER and no one can take that away from you!

Just mind wandering again :D

Tutorial JSF simple Application - Part 2 (Ajax Search)

2011-11-06T05:33:00.000-08:00

This example is compose of a simple search page that will display the result immediately, once the user type some characters in the input text box.

Below are some f:ajax attributes:
render = after the Ajax request, it will refresh the specified component id. on this example, we have defined that it should refresh the form with the dataTble ID
listener=specifies what action to be called when the event keyup was triggered

Without too much intro, lets go to the modified example. For the whole source code, please refer back to Tutorial JSF simple Application - Part 1.

Below are the modified files:
MembersDAOImpl.java
I just added a search by name method. This is just a basic example for a headstart for developing JSF application.
@Override
public List retrieveMembersByName(String value){

DetachedCriteria c = DetachedCriteria.forClass(MyData.class)
.add(Restrictions.like("name", "%" + value + "%"));

return hibernateTemplate.findByCriteria(c);
}

MembersDAO.java

public List retrieveMembersByName(String value);

SortBean.java
We specified a method with AjaxBehaviorEvent parameter
//Search
private String searchVal;
public void searchMember(AjaxBehaviorEvent event){
dataList = membersDao.retrieveMembersByName(searchVal);
}

public String getSearchVal() {
return searchVal;
}

public void setSearchVal(String searchVal) {
this.searchVal = searchVal;
}

memberList.xhtml


<table>
<tr>
<td>
<h:inputText value="#{sort_bean.searchVal}"
>
<f:ajax event="keyup" render="dataTble" listener="#{sort_bean.searchMember}"/>
</h:inputText>
</td>
</tr>
</table>

. . .

dataTble">

Using Ajax, we can update the parts of the page that we need to, which is specified on "render" attribute

To run:
1. execute mvn clean install
2. copy the war file from target folder to webapp folder
3. start the server
4. The page below will be displayed

Tutorial JSF simple Application - Part 1

2011-11-03T08:56:00.000-07:00

Hi All,

I'm back, after my mother went here for vacation, and one of my crush leaves me and our company to go to US for a girl (I hope thats me :D), I'm back to writing again my tutorial (start planting right :D)

This mini tutorial is just for reference. I would like to thank BalusC (balusc.blogspot.com) and Mkyong(mkyong.com) for having such a great tutorial site. most part of this tutorial is based on their tutorial.

The part 1 of this tutorial will consist mainly of simple CRUD and pagination.
No css for now, eventually, Ill try to add that :D

Installed software:
- apache-tomcat-6.0.33
- java 1.6.0_24
- Maven 2.1.0

Used Language and Framework in this exercise:
- Java
- JSF
- Hibernate
- Spring
- Maven

Below is the pages that will be displayed, once you follow this tutorial:

To run:
1. Open command prompt, go to root project directory (where pom is located) and execute: mvn clean install
2. Once successful build, go to the newly generated target folder and copy the war file.
3. Place the war file on tomcat webapp directory
4. Start the server
5. Go to url: http://localhost:8080/prjJsf/membersList.faces
6. The page I described above will be displayed.

Happy Coding!

Simple todo for Part 2 tutorial:
- use properties file
- use logging
- reset button
- clear the textbox after insert

Spring and Maven Simple Unit Test tutorial

2011-09-01T09:27:00.000-07:00

Before, I had created a simple tutorial for Spring unit test. though, I just save it on microsoft word, now im trying to place all my tutorials to my blog for easier access in the future.

Please take note that according to maven, this is the standard directory layout: http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html
src/main/java
src/main/resources
src/test/java
src/test/resources - place the property files needed for unit test

Folder Structure:
Src directory

Codes:
MemberDAO.java

package com.lai.dao;

public interface MemberDAO {
public String dummyStr();
}

MemberDAOImpl.java

package com.lai.dao.impl;

import com.lai.dao.MemberDAO;

public class MemberDAOImpl implements MemberDAO{

public String dummyStr(){

return "dummy";

}

Test directory

MyDaoTest.xml

package com;

import javax.annotation.Resource;
import junit.framework.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.lai.dao.MemberDAO;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class MyDaoTest {

@Resource(name = "memberDAO")
private MemberDAO memberDAO;

@Test
public void testDummy() {
Assert.assertEquals(memberDAO.dummyStr(), "dummy");
}
public MemberDAO getMemberDAO() {
return memberDAO;
}
public void setMemberDAO(MemberDAO memberDAO) {
this.memberDAO = memberDAO;
}
}

I separate the image for src and test directory to easily distinguish the folder structure.

MyDaoTest-context.xml
<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<bean id="memberDAO" class="com.lai.dao.impl.MemberDAOImpl">
</bean>

</beans>

It should be place under the test/resources/com directory, since the MyDaoTest is located in com directory.
For the naming convention, it should be <testClassName>-context.xml. It should be located on the same package name as the MyDaoTest

pom.xml

Once all the classes and configuration files has been defined, on the command directory, type:

mvn clean install

Thats it!

Try this

1. If you want to try to skip unit test, modify the MyDaoTest.

@Test
public void testDummy() {
Assert.assertEquals(memberDAO.dummyStr(), "dummyTest");
}

On command line, type mvn clean install
The result will be failed
now, try to type : mvn clean install -Dmaven.skip.test=true

It will now be build successful, because maven skip the unit test execution

2. To specify what unit test to run:
mvn clean install -Dtest=MyDaoTest,Test2 test
