Linux環境tomcat的setclasspath.sh檔

Tomcat在bin底下有一支setclasspath.sh可以設定tomcat所要使用的JDK與JRE。

用法範例:

JAVA_HOME=/usr/java/jdk/jdk1.6.0

JRE_HOME=/usr/java/jre/jre1.6.0

PATH=$JAVA_HOME/bin:$PATH

CLASSPATH=.:JAVA_HOME/lib

當你想讓tomcat不想使用環境預設的JDK時會用的到。

ubuntu Server 安裝 x-windows

Step1.請先參考ubuntu server apt proxy 設定
Setp2.x-windows install

• 台灣下載目前有點問題，請參考 http://jt-java.blogspot.com/，將server位置中有tw的都拿掉。
• 將被註解的#位址都打開
• apt-get update 
• apt-get upgrade 
• sudo aptitude install x-window-system-core
• sudo aptitude install xorg
• sudo aptitude install ubuntu-desktop
  or
  
  sudo aptitude install xubuntu-desktop
  or
  sudo aptitude install fluxbox fluxconf

• sudo aptitude install gdm
  or
  sudo aptitude install xdm    
• sudo reboot

Ubuntu Server apt proxy設定

Step1.
  #sudo vi /etc/apt/apt.conf


//若vi不能顯示中文時,將其環境先改成英文顯示

  #LANG=en_US 



Step2.
vi中按下i進入編輯模式，輸入：


Acquire::http::proxy "http://[proxy address]:[prot number]";
Acquire::https::proxy "https://[proxy address]:[prot number]";
Acquire::ftp::proxy "ftp://[proxy address]:[prot number]";


 vi中按下Esc回到一般模式，打入:w!儲存檔案


如此apt指令才能更新

Ubuntu安裝桌面捷徑工具

Ubuntu11.10拿掉了原本的的右鍵建立捷徑，可參考下列方式使用


安裝
sudo apt-get install --no-install-recommends gnome-panel


使用方法
gnome-desktop-item-edit ~/Desktop/ --create-new

ubuntu 新增啟動圖示

OS Ubuntu 10.04


Step1.新增啟動圖示

• 滑鼠右鍵→新增啟動圖示

Step2.欄位輸入數值 (這裡使用Eclipse作為範例)

• 類型：應用程式
• 名稱：eclipse
• 指令：/opt/eclipse/eclipse

若你想改變ICON點擊圖片即可，然後選擇你想要用的ICON檔案。
eclipse可以使用eclipse資料夾裡的icon.xpm。

Ubuntu 安裝 MySQL的JDBC

※apt安裝方式會自動把環境改成openJDK


Step1.先升級套件

• sudo apt-get update

Step2.安裝MySQL JDBC

• sudo apt-get install libmysql-java
  

Step3.設定環境變數

你可以設定在全體環境的/etc/profile或是個別使用者的/home/[user]/.bashrc。

參考環境變數profile

• sudo gedit /etc/profile

加入以下文字：

#MySQL JDBC environment

export CLASSPATH=$CLASSPATH:/usr/share/java/mysql.jar

Step4.載入新的環境變數設定

• source /etc/profile

Step5.看看現在的CLASSPATH

• echo $CLASSPATH

Step6.寫一個JAVA程式測試看看JDBC

package com.jt;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;

public class DBDemo 
{
 
   private static final String driver = "com.mysql.jdbc.Driver";
   private static final String url = "jdbc:mysql://127.0.0.1";
   private static final String username = "yourDB_username";
   private static final String password = "yourDB_password";
 
 /**
  * @param args
  */
 public static void main(String[] args) throws ClassNotFoundException,SQLException
 {
　　　　　　Connection conn;
　　　　　　Class.forName(driver);
　　　　　　conn  = DriverManager.getConnection(url, username, password);
　　　　　　System.out.println("Success");
　　　　　　conn.close();
 }
}

記得在eclipse中要把JDBC的jar給加進來

• Select Project Properties > Java Build Path
• Select Libries tab
• Click Add External Jars
• Choose the jar file, /usr/share/java/mysql.jar

加進來後可以看到：
