Tutorial 9 JSF, Facelets, Spring, Hibernate & Maven 2

This tutorial will put together tutorials 1-8. It will also incorporate dependenciesbetween the simpleWeb (c:\tutorials\jsimpleWeb) and simple(c:\tutorials\jsimple) projects as it would be in a real application.

Step 1:

Firstly create a dependency between simpleWeb and simple. In fact simpleWeb depends on simple

for business service functions and data access and storage. So we need to define this in ourpom.xml

file undersimpleWeb (c:\tutorials\jsimpleWeb).

Step 2: Exit out of eclipse and run the following maven command in a command

prompt:

C:\tutorials\simpleWeb>mvn eclipse:clean eclipse:eclipse

STEP:WorkAround

The JSF 1.2 requires eclipse web facet 2.5. You need to open the file

org.eclipse.wst.common.project.facet.core.xml underC:\tutorials\simpleWeb\.settingsas shown

below from version=2.4 to version=2.5. Every timeyou use the eclipse:clean command, you will haveto manually fix this up as shown below.

Step 3: Get back into eclipse and refresh the simpleWeb project by highlighting it and pressing F5.

Now right click and select Properties.

Since simpleWeb depends on simple maven2 has transitively brought all it dependencies into the

simpleWebs build path. In order to build a war file inside eclipse (pom.xml file is useful for buildingwar file and deploying externally) you need to define the J2EE module dependencies inside eclipse by

right clicking on simpleWeb and then selecting Properties and then J2EE module depndencies.

We need most jar files except for the el-api-1.0.jar & servlet-api-2.3.jar. Make sure that these 2 jars

are not ticked because they are available under Tomcats lib directory. All the ticked jar files end up in

/WEB-INF/lib directory when packaged inside Eclipse.

When you package it outside eclipse using mvn command mvn clean package pom.xml file will be

used for packaging these dependency jar files under/WEB-INF/lib inside the war file

Step 4: Lets make the following changes for this tutorial

App.java in simple project

package com.mytutorial;

import java.util.ArrayList;

import java.util.List;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

publicclassApp {

publicstaticvoid main(String[] args) {

ApplicationContext ctx = new ClassPathXmlApplicationContext( "applicationContext-

mytutorial.xml");

List courses = new ArrayList(10);

Course c1 = new Course();c1.setName("John");

c1.setCourse("Java");

courses.add(c1);

Course c2 = new Course();

c2.setName("Peter");

c2.setCourse("Hibernate");

courses.add(c2);

//CourseService service = new CourseServiceImpl();

CourseService service = (CourseService) ctx.getBean("courseService");

service.processCourse(courses);

List listCourses = service.getCourses(); //added

System.out.println("Retrieved courses and names are " + listCourses); //added

}

}

CourseService.java in simple project



publicinterface CourseService {

publicabstractvoidprocessCourse(List courses);

publicabstract List getCourses(); //added

}

CourseServiceImpl.java in simple project



publicclass CourseServiceImpl implements CourseService {

private CourseDao courseDao;

public CourseDao getCourseDao() {returncourseDao;

}

publicvoidsetCourseDao(CourseDao courseDao) {this.courseDao = courseDao;

}

//ModifiedpublicvoidprocessCourse(List courses) {

// CourseDao dao = new CourseDaoImpl();

courseDao.create(courses);

}

//Addedpublic List getCourses() {

List list = getCourseDao().findAll();return list;

}

}

CourseControllerBean.java in simpleWeb project



publicclass CourseControllerBean {

private CourseService courseService; // injected via spring

public List getCourses(){return getCourseService().getCourses();

}

public CourseService getCourseService() {returncourseService;

}

publicvoidsetCourseService(CourseService courseService) {this.courseService = courseService;

}

}

finally the web.xml file.

web.xml in simpleWeb project: find both spring applicationContext files.

The web.xml file should look like:

Step 5: Now install the simple project into maven repository with the new changes by:

C:\tutorials\simple>mvn clean install

This should install the simple-1.0-SNAPSHOT.jar under

C:\java\.m2\repository\com\mytutorial\simple\1.0-SNAPSHOT. Refresh the simpleWeb project inside

eclipse. Now Republish/package the simpleWeb project inside eclipse and start the Tomcat Server.

Make sure that your Database server is running:

C:\java\hsqldb>java -cp ./lib/hsqldb.jar org.hsqldb.Server


15/29

15

Also preferably run the DatabaseManeger

C:\java\hsqldb>java -cp ./lib/hsqldb.jar org.hsqldb.util.DatabaseManager

This will spawn a new window as shown:

Now open internet browser and type the following URL.

http://localhost:8080/simpleWeb/index.jsf


16/29

Click on link Click Me.

Click on button Hello

The Name & Course are empty. Now lets add some name and courses into the database either viaSQL statements in DatabaseManager or by running the App.java. Make sure that your HSQLDB

database server is running. To run App.java inside eclipse right click on App.java and then select

Run As and then select Java Application. After it has finished running go back to your internetexplorer and click on refresh button.

Tutorial 10 Maven 2

You may have noticed that there are some code repeats in pom.xml files insimple and simpleWeb projects. Maven2 child pom.xml files can inherit fromparent pom.xml file. In this tutorial lets clean up our project structures and thepom.xml files.

Step 1: Exit out of eclipse and restructure your projects underC:\tuitorials as follows:

Create a new folder simple-tutorial under c:\tutorials and move the simple & simpleWebunder simple-tutorial.

Step 2: Add the parent pom.xmlunder c:\tutorials\simple-tutorial as shown below.

The parent pom.xml file will be shared by both the pom.xml files underc:\tutorials\simple-tutorial\simple and c:\tutorials\simple-tutorial\simpleWeb.

c:\tutorials\simple-tutorial\pom.xml (parent pom.xml)

Step 4: Open up your eclipse workspace at C:\java\eclipse-tutorial-workspace. You will get ascreen as follows:

After publishing, run the Tomcat Server.

Step 6: Run the HSQLDB server in a command prompt and also open the DatabaseManager inanother command prompt.

Make sure that your Database server is running:

C:\java\hsqldb>java -cp ./lib/hsqldb.jar org.hsqldb.Server

Also preferably run the DatabaseManeger

C:\java\hsqldb>java -cp ./lib/hsqldb.jar org.hsqldb.util.DatabaseManager

This will spawn a new window as shown:

Thats all to it. Also try deploying outside Tomcat. Stop the Tomcat server inside eclipse.

If you already have a simpleWeb folder underC:\java\Tomcat6.0\webappsdelete it first. Then

copy the simpleWeb.war into Tomcats C:\java\Tomcat6.0\webappsfolder. Double click ontomcat6.exeto start the server.
