Install Java, Tomcat and MySQL on OpenSuse 11

Posted by leejeok on October 16, 2008

We will install the JRE, Tomcat and MySQL for hosting JSP web application with database backend. The installation are simple and will be done through the YaST management tools.

 

Launch YaST

Computer à YaST (at system menu) à enter root password à Software (at YaST control center) à Software Management.

 

Install JRE

1. We will require JRE in order to run Tomcat later. If you wish to do a development using Java programming, you may install both JDK and JRE together. At the filter field, type jdk.

 

2. Select java-1_6_0-openjdk for JRE (or java-1_6_0-openjdk-devel for JDK – for development). Next, click the Install button. Click Apply to download and install.

 

 

Install Tomcat

1. Download the tomcat 5.5 from http://tomcat.apache.org/ and saved it to desktop. Here, apache-tomcat-5.5.26.tar.gz been used. Right click on the file and click on Extract Here.

 

2. Rename the folder to tomcat for easier to remember the folder name. It is good idea to move the tomcat to /usr/local directory.

 

3. Type the command sudo mv tomcat-on-your-desktop-path /usr/local

 

4. You need to tell the tomcat where the JRE has been installed and to do this you need to define the JAVA_HOME environment variable in .bashrc file.  At the terminal, type the command: gedit ~/.bashrc

 

5. At the end of the file type export JAVA_HOME=your/java/home and save the file.

 

6. Start the tomcat with the command: sh /usr/loca/tomcat/bin/startup.sh

 

7. Open the Mozilla Firefox browser and browse to http://localhost:8080 and should see the Tomcat welcome screen.

 

8. To stop the tomcat type: sh /usr/loca/tomcat/bin/shutdown.sh

 

Install MySQL

1. Launch YaST. At the filters field type mysql and select the mysql package to install.

 

2. You may prompt to insert the openSuse-DVD 11. Insert the DVD and click retry to continue.

 

3. The installation process will take place.

Setup Java, Tomcat, MySQL, on Ubuntu Linux Machine for JSP hosting

Posted by leejeok on August 14, 2008

** If you had downloaded and installed Ubuntu 8.04 LTS Desktop Edition, you can skip the step below and goto step 8.

 

Install Ubuntu Ubuntu 8.04 LTS Server

Install the GNOME desktop (mostly used within this tutorial)

 

  1. Type sudo apt-get  install ubuntu-desktop to download and install.
  2. Type startx to start the GNOME


** You can install KDE desktop instead of GNOME.

To install KDE, type the command sudo apt-get install kubuntu-desktop

 

Install JDK 6 and JRE (Java)

 

  1. Within the GNOME, open the terminal. Applications à Accessories à Terminal
  2. Type sudo apt-get install sun-java6-jdk
  3. After successful install, you can do some verification to find out the installed JDK and JRE version. At the terminal, type javac –version for JDK and java –version for JRE.

 

Install Apache Tomcat 5.5

 

**Before installing the Tomcat 5.5, you will need to ensure that you had installed JDK and JRE.

 

  1. Download the tomcat 5.5 from http://tomcat.apache.org/ and saved it to desktop. Here, apache-tomcat-5.5.26.tar.gz been used.
  2. Right click apache-tomcat-5.5.26.tar.gz and click on Extract Here
  3. After extract, rename the folder to tomcat for easier to remember the folder name.
  4. Is good idea to move the tomcat to /usr/local directory. Type the command sudo mv “tomcat on desktop” to “/usr/local”

 

You need to tell the tomcat where the JDK has been installed and to do this you need to define the JAVA_HOME environment variable in .bashrc file.

 

  1. You are about to edit the .bashrc file. Please backup the file first before make any changes. The .bashrc is a hidden file and is located in your home directory.
  2. Open the terminal and type the command gedit ~/.bashrc (GNOME) or kate ~/.bashrc (KDE)
  3. At the end of the file type export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.06 and save the file.

 

Start and Stop tomcat

 

  1. At terminal, type sh /usr/local/tomcat/bin/startup.sh
  2. You can verify the success installation by open the Mozilla Firefox browser and browse to http://localhost:8080
  3. To shutdown tomcat – at terminal type sh /usr/local/tomcat/bin/shutdown.sh

JSP AND JAVABEANS – PASSING PARAMETER

Posted by leejeok on August 11, 2007

Description: Simple demo of javabean to receive and pass back parameter to JSP page. The objective here is to assemble all html codes to be place within the JSP page. Any processing of business logic would be code within the JAVABEANS. As a result, the HTML developer will focus any changes of the presentation / interface and allowing the JAVA developer to focus on the business logic to be define within the JAVABEANS.

Best Practice:

  1. JavaBean class must not have argument constructor.
  2. Provide the properties to customize the bean.
  3. Define the getter method to retrieve the property. No parametes and must return an object of the type of the property.
  4. Define the setter method to modify the property. Take a single parameter and return a void.

Technology Coverage: JSP and JAVABEANS

Sample of the code of index.jsp:

<jsp:useBean id=”_detailbean” class=”org.detailbean” scope=”session”/>

   <%
   String name = request.getParameter(“name”);
   if(name!= null)
       _detailbean.setName(name);
   %>
<html>
    <head>
        <meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″>
        <title>JSP Page</title>
    </head>
    <body>
        <form name=myform method=post>
            Param Value: <input type=”text” name=”name” value=”” />
            <input type=”submit” value=”Submit” />
            <br>
            Your parameter: <%=_detailbean.getName()%>
        </form>
    </body>
</html>

Sample of the code of detailbean.java:

package org;
public class detailbean implements java.io.Serializable {
    private String name = “”;
   
    /** Creates a new instance of checkbean */
    public detailbean() {
    }
   
    //define getter
    public String getName() {
        return name;
    }
   
    //define setter
    public void setName(String name) {
        this.name = name;
    }
}

Result

I have been using NetBeans 5.5 to perform the development. Full souce code available Click HERE.
