Setting up the Java EE Environment under Linux environment

One, JDK installation (installed in the/usr/java directory)
1. Download: Jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
Address: Http://jx.newhua.com/down/jdk-7-ea-bin-b26-linux-i586-24_apr_2008.zip
Unzip the zip format under Windows Jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
and upload it to the Linux server's/usr/java directory.
2. Add executable permissions to the file
[Email protected] java]# chmod x jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
3. Executive Jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
[Email protected] java]#./jdk-7-ea-bin-b26-linux-i586-24_apr_2008.bin
Automatically install the build directory jdk1.7.0
4. Configure Environment variables
There are three ways to configure environment variables (Modify the/etc/profile file, modify the. bashrc file under the user directory, and modify it directly under the shell). I modified the/etc/profile file:
[Email protected] java]# Vi/etc/profile
After opening the file, press the I key to add after the file:
java_home=/usr/java/jdk1.7.0
Path= $JAVA _home/bin: $PATH
Classpath=.: $JAVA _home/lib/tools.jar: $JAVA _home/lib/dt.jar or.: $JAVA _home/jre/lib/rt.jar
Export Java_home PATH CLASSPATH (Configure global variables)
Press the ESC key
Input: Wq save exit.
Restarting the server
6. Test the configuration environment
Write a simple HelloWorld to test it.
[Email protected] java]# VI Helloworld.java
File, enter:
public class helloworld{
public static void Main (String args[]) {
System.out.println ("Hello World in linux!!");
}
}
: Wq Save Exit
[Email protected] java]# Javac Helloworld.java
No errors, Next:
[Email protected] java]# java HelloWorld

Second, Tomcat installation: (also installed in the/usr/java directory)

: http://mirror.vmmatrix.net/apache/tomcat/tomcat-5/v5.0.28/bin/jakarta-tomcat-5.0.28.tar.gz
1, unzip to/usr/ Java directory:
[[email protected] java]# tar-zxvf jakarta-tomcat-5.0.28.tar.gz
/usr/ A new directory will appear in the Java directory jakarta-tomcat-5.0.28
2, creating a file Link:
[[email protected] java]# ln-s jakarta-tomcat-5.0.28 Tomcat
3, configuration catalina_home:
[[email protected] java]# vi/etc/profile
Add at end of file
catalina_home=/usr/ Java/tomcat
Export catalina_home
: Wq Save exit
4, start tomcat:
input
[[email protected] tomcat]# bin/ startup.sh
or
[[email protected] tomcat]# bin/catalina.sh run

Close Tomcat by:
[[email protected] tomcat]# bin/catalina.sh stop
or [[email protected] tomcat]# bin/shutdown.sh
Shell output:
Using catalina_base:/usr/java/tomcat
Using Catalina_home:/usr/java/tomcat
Using Catalina_tmpdir:/usr/java/tomcat/temp
Using Java_home:/usr/java/jdk1.7.0
5, input in the browser (note: This refers to the Linux virtual machine on the machine, on non-Linux native browser access, to enter the Linux virtual machine IP address): http://localhost:8080 will appear tomcat welcome page
6. Managing Tomcat:
[Email protected] tomcat]# VI conf/tomcat-users.xml
Join in and between:
7. Restart the system:
Browser input: Http://localhost:8080/manager log in and you can manage it.
Enter http://localhost:8080/manager/html to manage your project.
Linux system does not open 8080 ports by default, open port 8080 can be:
[Email protected] ~]# cd/etc/sysconfig/
[Email protected] sysconfig]# VI iptables
Add this sentence:-a rh-firewall-1-input-m State--state new-m tcp-p TCP--dport 8080-j ACCEPT (different distributions have different wording)
