Configure JRE, JDK, eclipse, and tomcat 7.0.5 in Ubuntu 10.10

1. Install JDK

1.1, to the official website to download the relevant JDK, download here is the jdk-6u23-linux-i586.bin.

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

 

1.2 create a "Java folder" in the "Administrator personal folder" (I .e., location-> main folder-> administrator );

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

(The path can be modified according to your actual situation. Here we use the Java folder under administrator as an example.
)

 

1.3 open the 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

 

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.

3.1, to the official website to download the relevant eclipse, Here download is the eclipse-jee-helios-SR1-linux-gtk.tar.gz (javaee ).

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

4.2 put the downloaded apache-tomcat-7.0.5.tar.gz in the Java folder, decompress and name it tomcat7 (if you like to execute command line, you can execute

(Decompress) sudo tar zxvf APACHE-Tomcat-7.0.5

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

Command)

 

4.3 bind files (CD Java/tomcat7/bin) under Tomcat 7 on the terminal)

(Here we use the vim editor or gedit, that is, enter sudo gedit Catalina. Sh)

Input: sudo Vim Catalina. Sh

In

Cygwin = false

Os400 = false

Darwin = false

Case "'uname'" in

Cygwin *) cygwin = true ;;

Os400 *) os400 = true ;;

Darwin *) Darwin = true ;;

Add:

Java_home =/home/Administrator/Java/jdk1.6.0 _ 23

Java_opts = "-server-xms512m-xmx1024m-XX: permsize = 600 m-XX: maxpermsize = 600 m-DCOM. Sun. Management. jmxremote"

 

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"

Connectiontimeout = "20000"

Redirectport = "8443" type = "regxph" text = "yourobjectname"/>

4.5. the Java/tomcat7/bin folder has been entered.

Input: sudo./starup. Sh

Start Tomcat 7.

If

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
