Setting up environment for java application development

Hello,

This is the first part1 of my series on Maven, Spring and hibernate put together. I hope you it will be appreciated that I started from this point. Let’s get started:

Install java development toolkit

windows machine
download and install jdk 7+ in :

Linux Ubuntu
[bash]
$ sudo apt -get install openjdk-7-jdk #this will install l java app
[/bash]

Mac

• Download java-package.dmg and double click

install subversion

Windows Machine

• download and install from collab.net or install tortoise subversion install subversion

Linux Ubuntu
[bash]
$ sudo apt-get install subversion #or install rabbit svn from repository
[/bash]

install maven

Windows machine

• download binaries from adorable maven site
• unpacked inside C:\\maven

Linux Ubuntu

installing maven in /usr/local/maven it’s strongly advised on Linux
download and install maven under the indicated directory. Check this to get it done properly

install apache tomcat

Windows machine
For the purpose of a development machine we suggest, installating in C:\\java folder
download and unzip tomcat under the mentioned directory.

Linux Ubuntu
We also suggest to download the binaries files and unzip it under /home/yourname/tomcat or under /opt/tomcat making sure you have full privilege on the folder

Mac
download binaries and unzip under /Users/yourname/tomcat

Install mysql server

Linux Ubuntu

[bash]
$ sudo apt-get install mysql-server mysql-client
[/bash]

Windows

Find all necessary information on netbeans

Mac
Find all necessary information on mysql

set environment variables

setting java_home environment

Windows machine

• go to desktop
• right click “my computer ” icon
• click on advanced tab
• click on environment variable button
• under system variable click on new button
• in variable name textbox write JAVA_HOME
• in variable value textbox write path-to-your-java-folder (eg C:\\Program Flies\Java\Jdk-version-number)

Linux Ubuntu

[bash]
sudo nano /etc/environment
#append to the file:
JAVA_HOME="/path/to/your/java" #eg: /usr/lib/jvm/java-1.7.0-openjdk-amd64
[/bash]
crtl+x to save

Mac
On Mac java home is usually under /Libraby/Java/Home, but there is a tool to find out , run in a terminal /usr/libexec/java_home to see the location of java home
[bash]
pico ~/.bash_profile or touch ~/.bash_profile
#append the following to the file
export JAVA_HOME=$(/usr/libexec/java_home)
[/bash]
ctrl+x to save

setting of maven home

Windows machine

• go to desktop
• right click “my computer ” icon
• click on advanced tab
• click on environment variable button
• under system variable click on new button
• in variable name textbox write M2_HOME
• in variable value textbox write path-to-your-maven-folder (eg C:\\Maven)

Linux Ubuntu
[bash]
sudo nano /etc/environment
#append to the file: M2_HOME="/path/to/your/maven" eg: /usr/local/maven
[/bash]
crtl+x to save

Mac
[bash]
pico ~/.bash_profile or touch ~/.bash_profile
export M2_HOME=/path/to/your/maven
[/bash]
ctrl+x to save

setting of catalina home

• go to desktop
• right click “my computer ” icon
• click on advanced tab
• click on environment variable button
• under system variable click on new button
• in variable name textbox write CATALINA_HOME
• in variable value textbox write path-to-your-tomcat-folder (eg C:\\Tomcat)

Linux Ubuntu
[bash]
sudo nano /etc/environment
#append to the file:
CATALINA_HOME="/path/to/your/tomcat" eg: /usr/local/tomcat. or /home/yourprofilenam/tomcat or /opt/tomcat
[/bash]
crtl+x to save
in variable value textbox write path-to-your-tomcat-folder (eg C:\\Tomcat)

Mac
[bash]
pico ~/.bash_profile or touch ~/.bash_profile
#append to the file the following
export CATALINA_HOME=/path/to/your/tomcat
[/bash]
ctrl+x to save

Attention Required

When running some of dreamoval web appliations , some might cause tomcat to run out of memory. That is because tomcat is running with default max imum memory size. A quick fix to that is to set some parameter to tomcat because it starts. That is done by putting a setenv.sh or setenv.bat file under the bin folder. These are just default “increased” value, thus it can be adjusted based on need

Windows machine

• change directory to Drive:\\path\to\your\tomcat\bin
• create setenv.bat file
• put in: set CATALINA_OPTS= -server -Xms512m -Xmx768M -XX:MaxPermSize=512m -XX:+CMSClassUnloadingEnabled

save and close the file

Linux and Mac machine
[bash]
cd /path/to/your/tomcat/bin
nano setenv.sh
#append the following to it
export CATALINA_OPTS="-server -Xms512m -Xmx768M -XX:MaxPermSize=512m -XX:+CMSClassUnloadingEnabled"
[/bash]
save and close the file

That’s it you are ready to go. Next we will talk about setting up your project
