Java DRP Project Combat: Environment Construction

Profile

We want to start a development of Java projects, then we need to build a Java development environment, then build a Java development environment, what needs, and what to note.

Process

Let me first make a list of the software and software that I use to build the Java environment, JDK, Jre, MyEclipse, Oracle, Tomcat, Pl/sqldeveloper, Powerdesign, and Rational Rose.

Before we can build Java, we have to install all these software on our computers, how to install we only say two, a Java running environment includes JDK and JRE and the other is database Oracle. There is also a point to be said about the development of software generally have 32 and 64 points, on 32-bit operating system can only install 32-bit software, on the 64-bit operating system can install 32-bit can also install 64-bit. So when we install the software, we try to unify the development environment. My operating system is 64-bit and my development environment is 32-bit: JDK, Jre, MyEclipse, Tomcat are 32-bit, Oracle is 64-bit.

Development environment Installation

Installing JDK and JRE

About JDK and JRE we have already introduced in previous blog no more redundancy, enter the theme my Java environment installs 1.7 version 32 bits.

Download Address bit: HTTP://PAN.BAIDU.COM/S/1MG5JVSC

The following is a detailed installation step,

1. Double-click to run Jdk-8u11-windows-i586.exe

2, modify the installation path, change to C:\jdk1.7.0_45 (can be customized)

3, the operation process, the installation of JRE to C:\JDK1.7.0_45\JRE (can be customized)

4, right button My Computer-> properties > Advanced system Settings > Environment variables, make the following settings.

5, add the following in the user variable:

Java_home=c:\jdk1.7.0_45

Path=.; %java_home%\bin;%java_home%\jre\bin;%path%;

Classpath=.; %java_home%\lib\dt.jar;%java_home%\lib\tools.jar;

6, pull up the command line window (win + R after the input cmd)

7, input java–version, the appearance of the interface below, the installation of JDK success

Install oracle_11g

Here because our project requires the database on Oracle, all we have installed here is the oracle_11g 64-bit version, the database selection can be selected according to the requirements. Oracle databases and Oracle clients are required for installation of Oracle.

Oracle database, client, installation documentation download address: Http://pan.baidu.com/s/1c0IkW6W

1. Install the Oracle_11 database, you can refer to the installation documentation.:

2. Install Oracle client. EXE, follow the prompts step by step, simpler.
