Lab 20 – Filter Query

Update Inventory.hbm.xml with the following.



<hibernate-mapping>



</id>




<filter name="byQuantity"condition="quantity >= :theQuantity"/>

</class>

<filter-def name="byQuantity"><filter-param name="theQuantity" type="integer"/>

</filter-def>

Create a new class named TestFilterQuery and add the following.

package tests;



public class TestFilterQuery {

/*** @param args*/


try {// Filter QuerySession s = HibernateUtil.getSessionFactory().


"*** Query item 1 for inventory quantity " +"of at least 5 ***");

s.enableFilter("byQuantity").setParameter("theQuantity", new Integer(5));

204

Import the following JAR files to the WEB-INF\lib folder.

205

Create a simple JSP named test.jsp to test the connection.

206


<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<sql:query var="rs" dataSource="jdbc/PetDB">SELECT PET_ID, NAME FROM PET</sql:query>

<html><head>

<title>DB Test</title></head><body>

<h2>Results</h2>

<c:forEach var="row" items="${rs.rows}">ID ${row.PET_ID} Name ${row.NAME} 

</c:forEach>

</body></html>

207

Run test.jsp on the Server and you should see the following.

208

Using a Servlet.

Create a new package named servlets.

209

Create a new Servlet named TestServlet

210


package servlets;

import java.io.IOException;import java.io.PrintWriter;import java.sql.Connection;import java.sql.ResultSet;import java.sql.Statement;

import javax.naming.InitialContext;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.sql.DataSource;

/*** Servlet implementation class for Servlet: TestServlet**/public class TestServlet extends

javax.servlet.http.HttpServletimplements javax.servlet.Servlet {

static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request,HttpServletResponse response)

throws ServletException, IOException {response.setContentType("text/html");PrintWriter out = response.getWriter();out.println("<HTML>");out.println("<HEAD>");out.println("<TITLE>Test JNDI</TITLE>");out.println("</HEAD>");out.println("<BODY>");

try {InitialContext initCtx =

new InitialContext();DataSource ds = (DataSource)

initCtx.lookup("java:comp/env/jdbc/PetDB");Connection conn = ds.getConnection();

out.println(" ");out.println(

"Connection from DataSource successfully opened! ");

211

Statement stmt = conn.createStatement();ResultSet rs = stmt.executeQuery(

"select * from PET");

while (rs.next() ) {String onerow = "Pet ID: " + rs.getString("PET_ID")

+ ", Name: " + rs.getString("NAME")+ ", Description: " + rs.getString("DESCRIPTION") +" ";

out.println(onerow);}

rs.close();stmt.close();conn.close();initCtx.close();


"Connection from DataSource successfully closed! ");}catch(Exception e) {


"Connection from DataSource NOT successfully opened! ");out.println(e.getMessage() + " ");

}

out.println(" </BODY>");out.println("</HTML>");out.flush();out.close();

}

}

212

Run the Servlet on the Server and you should see the following.

213

Use Hibernate with the Tomcat Connection Pool.

Create a ServletContextListener as below.

214

Add the following.

package servlets;

import javax.servlet.ServletContextListener;import javax.servlet.ServletContextEvent;

public class HibernateAppListener implements ServletContextListener{

/* Application Startup Event */public void contextInitialized(ServletContextEvent ce) {

System.out.println("Connect");

try {System.out.println(

"In HibernateAppListener.contextInitialized");

Class.forName("utils.HibernateUtil").newInstance();

System.out.println("In HibernateAppListener, " +"Class.forName for utils.HibernateUtil successful");

}catch (Exception e) {

System.out.println("In HibernateAppListener, " +" Class.forName for utils.HibernateUtil throws Exception");

}}

/* Application Shutdown Event */public void contextDestroyed(ServletContextEvent ce) {}

}

215

Create a new Servlet.

package servlets;

import java.io.IOException;import java.io.PrintWriter;import java.util.Iterator;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.hibernate.Query;import org.hibernate.Session;import pets.Pet;

import utils.HibernateUtil;

public class HibernateServlet extendsjavax.servlet.http.HttpServletimplements javax.servlet.Servlet {static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request,HttpServletResponse response)

throws ServletException, IOException {response.setContentType("text/html");PrintWriter out = response.getWriter();out.println("<HTML>");out.println("<HEAD>");out.println("<TITLE>Test JNDI</TITLE>");out.println("</HEAD>");out.println("<BODY>");

try {Session session =HibernateUtil.getSessionFactory().openSession();

session.beginTransaction();

String SQL_QUERY = "FROM Pet";Query query = session.createQuery(SQL_QUERY);for(Iterator it=query.iterate(); it.hasNext(); ) {

Pet pet=(Pet)it.next();out.println(pet + (" ");

}

session.getTransaction().commit();

216

}catch(Exception e) {


"Connection from DataSource NOT successfully opened! ");out.println(e.getMessage() + " ");

}

out.println(" </BODY>");out.println("</HTML>");out.flush();out.close();

}

}

217

Update web.xml

<listener><listener-class>servlets.HibernateAppListener</listener-class>

</listener>

218

Update hibernate.cfg.xml





<property name="connection.datasource">

java:comp/env/jdbc/PetDB</property>



<property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect

</property><property name="hibernate.connection.pool_size">

1</property>


True</property>

219

<property name="hibernate.current_session_context_class">

thread</property>

<property name="hibernate.cache.provider_class">

org.hibernate.cache.EhCacheProvider</property>

<mapping resource="resources/Pet.hbm.xml"/><mapping resource="resources/Inventory.hbm.xml"/>

</session-factory>

220

Copy the Hibernate JARs to Tomcat.

221

Run the Servlet on the Server and you should see the following.

222
