1. Install JDK

1.1 download the related JDK from the official website.

Here the download 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 folder"

That is, location-> main folder-> administrator;

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

You can modify the path according to your actual situation. Here we use the Java folder under administrator as an example.

1.3 open "terminal"

Application> attachment> Terminal

Input:

 
 

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

(The user password to be entered may be encountered)

2. Set system variables in the java_home Environment

2.1. Here, CTRL + H can be used to view hidden files. It is a useful shortcut key.

Input:

 
 

  
  
sudo gedit /etc/environment 
 
 

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 is

Set 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 PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin 
 
 

That is

2.3 log out of the user and check the JDK version.

Input:

 
 

  
  
java -version 
 
 

That is

JRE and JDK are successfully installed.

3. Install eclipse.

(Named tomcat7) sudo mv apache-Tomcat-7.05 tomcat7

4.3 bind files under Tomcat 7 on the terminal

(CD Java/tomcat7/bin)

Here we use the vim editor or gedit,Input:

 
 

  
  
sudo gedit catalina.sh 
 
 

When you enter:

 
 

  
  
sudo vim catalina.sh 
 
 

Get

 
 

  
  
cygwin=false 
  
  
os400=false 
  
  
darwin=false 
  
  
case "`uname`" in 
  
  
CYGWIN*) cygwin=true;; 
  
  
OS400*) os400=true;;

Port 4.4 and tomcat7.0.5 (the default port of tomcat7.0.5 is 8080). If a conflict occurs, modify the port in the following file.

In the tomcat7/CONF/server. xml file:

 
 

  
  
<Connector port="9090" protocol="HTTP/1.1"
