Installing the JDK under Ubuntu 10.10 Configuring Eclipse and Tomcat

1. Installing the JDK

1.1. Download the relevant JDK to the website

The download here is Jdk-6u23-linux-i586.bin.

:http://www.oracle.com/technetwork/java/javase/downloads/index.html

1.2. Create a "Java folder" in "Administrator Personal Folders"

Location---Home folder->administrator;

Place the downloaded Jdk-6u23-linux-i586.bin in this Java folder.

The path can be changed according to your actual situation, here the Java folder under administrator as an example

Applications, accessories, terminals

input :

 
   
  

  
    
   
sudo sh jdk-6u23-linux-i586.bin
 
   
  

(You may encounter a user password to enter)

2. Set Java_home Environment System variables

2.1, here ctrl+h can see hidden files, more useful shortcut keys.

Input:

 
   
  

  
    
   
sudo gedit/etc/environment
 
   
  

In the file, add:

 
   
  

  
    
   
Export java_home=/home/administrator/java/jdk1.6.0_23
  
    
   
Export jre_home=/HOME/ADMINISTRATOR/JAVA/JDK1.6.0_23/JRE
  
    
   
Export CLASSPATH= $CLASSPATH: $JAVA _home/lib: $JAVA _home/jre/lib
 
   
  

That

Setting Java_home Environment System variables

2.2. Similarly, modify the second file

Input:

 
   
  

  
    
   
sudo gedit/etc/profile
 
   
  

Add the following statement before Umask 022:

 
   
  
 
    
   
export java_home  =/home/administrator/java/ jdk1.6.0_23  
 
    
   
export JRE _home  =/home/administrator/java/jdk1.6.0_23/jre  
 
    
   
export classpath  = $CLASSPATH: $JAVA _home/lib: $JAVA _ home/jre/lib  
 
    
   
export  = $JAVA _home/bin: $JAVA _home/jre/bin: $PATH: $HOME/bin  
 
   
  
 

That

2.3, log off the user, detect JDK version.

Input:

 
   
  

  
    
   
Java-version
 
   
  

That

Install JRE, JDK successful

3. Install Eclipse.

3.1, to the official website download the relevant eclipse

The download here is eclipse-jee-helios-sr1-linux-gtk.tar.gz (ie Java EE).

:http://www.eclipse.org/downloads/

4.2. Place the downloaded apache-tomcat-7.0.5.tar.gz in the Java folder, unzip it and name it TOMCAT7

Commands that you can execute if you prefer to execute the command line

(unzip) sudo tar zxvf apache-tomcat-7.0.5

(named TOMCAT7) sudo mv apache-tomcat-7.05 TOMCAT7

4.3, the bin file under the terminal TOMCAT7

(i.e. CD Java/tomcat7/bin)

Here is the VIM editor open, you can also open with gedit, that is, enter:

Get

  
 

   
  

  
Cygwin=false
   
  

  
os400=false
   
  

  
Darwin=false
   
  

  
Case "' uname '" in
   
  

  
cygwin*) CYGWIN=true;;
   
  

  
os400*) os400=true;;
   
  

  
darwin*) Darwin=true;;
  
 

Added above:

 
   
  

  
    
   
java_home=/home/administrator/java/jdk1.6.0_23
  
    
   
java_opts="-server-xms512m-xmx1024m-xx:permsize=600m-xx:maxpermsize=600m- Dcom.sun.management.jmxremote "

Using  catalina_base:   /home/administrator/java/tomcat7  
 
   
using catalina_home:   /home/administrator/java/tomcat7  
 
   
using catalina_tmpdir: /home/ administrator/java/tomcat7/temp  
 
   
Using JRE_HOME :         /home/administrator/java/jdk1.6.0_23  
 
   
using classpath:       /home/administrator/ java/tomcat7/bin/bootstrap.jar:/home/administrator/java/tomcat7/bin/tomcat-juli.jar
