The mail settings are stored in mail.properties and the beans about mail sender are set in applicationContext-service.xml. They are mailEngine, mainlSender. We don't need to change mailEngine. But we must add a new property for mailSender because the default setting does not support mail authorization in many mail servers. The new property is below:
?? <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
??????? <property name="host" value="${mail.host}"/>
??????? <property name="username" value="${mail.username}"/>
??????? <property name="password" value="${mail.password}"/>
??????? <property name="javaMailProperties">
?????????? <props>
???????????? <prop key="mail.smtp.auth">true</prop>
?????????? </props>
??????? </property>
??? </bean>
??? The red lines are new. we have to add them. Otherwise the mail function in Appfuse does not work.

Lesson: 檢測類examing class

1.Retrieving Class Objects
獲取一個Class對象(metadata)

a,從對象的實例獲取。
Class c = mystery.getClass();//(return Class)
b,從子類的實例獲取
TextField t = new TextField();
Class c = t.getClass();
Class s = c.getSuperclass();
c,知道類名，則可以把.class加入到名字之后來獲取。
Class c = java.awt.Button.class;
d,如果類名在編譯時是未知的，則可以使用Class.forName()方法來獲取.
Class c = Class.forName(classString);

2.Getting the Class Name
獲取類名稱
c.getName();

例如：
import java.lang.reflect.*;
import java.awt.*;

class SampleName {

public static void main(String[] args) {
Button b = new Button();
printName(b);
}

static void printName(Object o) {
Class c = o.getClass();
String s = c.getName();
System.out.println(s);
}
}


3.Discovering Class Modifiers
檢索修改符
a.通過getModifiers（）方法獲取一個整型標識值。
b.通過java.reflect.Modifier對象的isPublic, isAbstract, 和 isFinal方法判斷此值.

例如：
import java.lang.reflect.*;
import java.awt.*;

class SampleModifier {

public static void main(String[] args) {
String s = new String();
printModifiers(s);
}

public static void printModifiers(Object o) {
Class c = o.getClass();
int m = c.getModifiers();
if (Modifier.isPublic(m))
System.out.println("public");
if (Modifier.isAbstract(m))
System.out.println("abstract");
if (Modifier.isFinal(m))
System.out.println("final");
}
}


4.Finding Superclasses
檢索父類
例如：
import java.lang.reflect.*;
import java.awt.*;

class SampleSuper {

public static void main(String[] args) {
Button b = new Button();
printSuperclasses(b);
}

static void printSuperclasses(Object o) {
Class subclass = o.getClass();
Class superclass = subclass.getSuperclass();
while (superclass != null) {
String className = superclass.getName();
System.out.println(className);
subclass = superclass;
superclass = subclass.getSuperclass();
}
}
}


5.Identifying the Interfaces Implemented by a Class
檢索指定類實現的接口
例如：
import java.lang.reflect.*;
import java.io.*;

class SampleInterface {

public static void main(String[] args) {
try {
RandomAccessFile r = new RandomAccessFile("myfile", "r");
printInterfaceNames(r);
} catch (IOException e) {
System.out.println(e);
}
}

static void printInterfaceNames(Object o) {
Class c = o.getClass();
Class[] theInterfaces = c.getInterfaces();
for (int i = 0; i < theInterfaces.length; i++) {
String interfaceName = theInterfaces[i].getName();
System.out.println(interfaceName);
}
}
}
6.Examining Interfaces
判定一個類是不是接口

import java.lang.reflect.*;
import java.util.*;

class SampleCheckInterface {

public static void main(String[] args) {
Class thread = Thread.class;
Class runnable = Runnable.class;
verifyInterface(thread);
verifyInterface(runnable);
}

static void verifyInterface(Class c) {
String name = c.getName();
if (c.isInterface()) {
System.out.println(name + " is an interface.");
} else {
System.out.println(name + " is a class.");
}
}
}



如：c.isInterface()

7.Identifying Class Fields
找出指定類所有的域成員
每個數據成員可以用java.reflect.Field來封閉其名稱，類型，修改符的集合。
也可以通過相應的方法獲取或設置到該成員的值。

如：
import java.lang.reflect.*;
import java.awt.*;

class SampleField {

public static void main(String[] args) {
GridBagConstraints g = new GridBagConstraints();
printFieldNames(g);
}

static void printFieldNames(Object o) {
Class c = o.getClass();
Field[] publicFields = c.getFields();
for (int i = 0; i < publicFields.length; i++) {
String fieldName = publicFields[i].getName();
Class typeClass = publicFields[i].getType();
String fieldType = typeClass.getName();
System.out.println("Name: " + fieldName +
", Type: " + fieldType);
}
}
}



8.Discovering Class Constructors
檢索指定類的構造函數

當創建一個類的實例時，是通過檢造方法來作的，這種方法可以被重載。
每一個構造方法可以用類Constructor來描述，，包括名稱，修飾符，參數類型(Class[])，和異常列表。
可以通過一個Class的getConstructors方法獲取到該類的Constructor數組。
例程：
import java.lang.reflect.*;
import java.awt.*;

class SampleConstructor {

public static void main(String[] args) {
Rectangle r = new Rectangle();
showConstructors(r);
}

static void showConstructors(Object o) {
Class c = o.getClass();
Constructor[] theConstructors = c.getConstructors();
for (int i = 0; i < theConstructors.length; i++) {
System.out.print("( ");
Class[] parameterTypes =
theConstructors[i].getParameterTypes();
for (int k = 0; k < parameterTypes.length; k ++) {
String parameterString = parameterTypes[k].getName();
System.out.print(parameterString + " ");
}
System.out.println(")");
}
}
}





9.Obtaining Method Information
檢索方法
可以找到隸屬于一個類的所有方法，通過getMethods包含Method數組，進而得到該方法的返回類型，修飾符，方法名稱，參數列表
步驟：
a.指定類的Class Object
b.getMethods()獲取Method[]對象
c,遍歷該數組對象

例程：

import java.lang.reflect.*;
import java.awt.*;

class SampleMethod {

public static void main(String[] args) {
Polygon p = new Polygon();
showMethods(p);
}

static void showMethods(Object o) {
Class c = o.getClass();
Method[] theMethods = c.getMethods();
for (int i = 0; i < theMethods.length; i++) {
String methodString = theMethods[i].getName();
System.out.println("Name: " + methodString);
String returnString =
theMethods[i].getReturnType().getName();
System.out.println(" Return Type: " + returnString);
Class[] parameterTypes = theMethods[i].getParameterTypes();
System.out.print(" Parameter Types:");
for (int k = 0; k < parameterTypes.length; k ++) {
String parameterString = parameterTypes[k].getName();
System.out.print(" " + parameterString);
}
System.out.println();
}
}
}

import org.hibernate.cfg.Configuration;

import org.hibernate.mapping.PersistentClass;

public class HibernateConfigurationHelper {

?????? private static Configuration hibernateConf = new Configuration();

?????? private static PersistentClass getPersistentClass(Class clazz) {

????????????? synchronized (HibernateConfigurationHelper.class) {

???????????????????? PersistentClass pc = hibernateConf.getClassMapping(clazz.getName());

???????????????????? if (pc == null) {

??????????????????????????? hibernateConf = hibernateConf.addClass(clazz);

??????????????????????????? pc = hibernateConf.getClassMapping(clazz.getName());

???????????????????? }

???????????????????? return pc;

????????????? }

?????? }

?????? public static String getTableName(Class clazz) {

????????????? return getPersistentClass(clazz).getTable().getName();

?????? }

?????? public static String getPkColumnName(Class clazz) {

????????????? return getPersistentClass(clazz).getTable().getPrimaryKey()

??????????????????????????? .getColumn(0).getName();

?????? }

}

以前使用 spring 的 hibernateTemplate 時，發現都無法用 lazyloading 特性因為一旦使用，會報 session close 錯誤，幾經查找資料，終于找到解決方法，就是在 web.xml 中加入下列 filter ：

?

<filter>

???????<filter-name>hibernateFilter</filter-name>

???????<filter-class>

???????????org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

???????</filter-class>

????</filter>

????<filter-mapping>

???????<filter-name>hibernateFilter</filter-name>

???????<url-pattern>/*</url-pattern>

????</filter-mapping>

Appfuse is a good framework for developing web projects. But the width of tables in web pages are fixed. It looks as if a little of ugly. Fortunately, we can repair it as the following method:

1. opens ${ProjectName}/styles/layout.css and locates at div#page. Replaces “width:781px” with “width: 95%”;
2. opens layout-navtop-subright.css in the same folder. Locates at div#content. Replaces “width:701px”(or something else like this) with “width 95%”.
3. Refresh the html page and you will find the tables are beautiful. Enjoy it.

??? Step1. Open registry and locate to \HKEY_CLASSES_ROOT\Folder\shell;
??? Step2. Add new key named "Windows Command" and add a sub key of "Command", the default? value of the new sub key is "cmd /K cd /d %L"
??? Step3. That's all.
???

找開global.js, 找到以下函數:

function addFocusHandlers(elements) {
??? for (i=0; i < elements.length; i++) {
??????? if (elements[i].type != "button" && elements[i].type != "submit" &&
??????????? elements[i].type != "reset" && elements[i].type != "checkbox" && elements[i].type != "radio") {
??????????? if (!elements[i].getAttribute('readonly') && !elements[i].getAttribute('disabled')) {
??????????????? elements[i].onfocus=function() {this.style.backgroundColor='#ffd';this.select()};
??????????????? elements[i].onmouseover=function() {this.style.backgroundColor='#ffd'};
??????????????? // elements[i].onblur=function() {this.style.backgroundColor='';} 就是這一句話使jsp(html)中的onblur事件不能觸發
??????????????? elements[i].onmouseout=function() {this.style.backgroundColor='';}
??????????? }
??????? }
??? }
}
將其屏蔽掉即可。我還沒有發現屏蔽后對系統會有什么樣的影響。

Step0. 假設已經安裝好JRE環境變量，ANT, Tomcat也安裝好.
Step 1.? 安裝AppFuse, 假設其安裝文件夾為d:\temp\AppFuse;
Step2. 以CDM.exe 方式 進入d:\temp\AppFuse, 運行Ant new, 按提示輸入新項目的名稱（假設為CN2)，數據庫連接名稱(假設為CN2)，包名(假設為com.pplus)。Ant 會在d:\temp\CN2中生成新的項目；
Step3. 仍以cmd.exe 方式進入d:\temp\CN2，運行Ant setup-db, 這時會生成數據庫。然后再運行Ant setup, 程序會生成我們所需要的整個項目。
Step4. 啟動Eclipse,? import->Existing Projects into Workspace, 將剛才創建的新項目導入，這里新項目的名稱為CN2.
Step5. 在Eclipse中Window->Show View->Ant,? 打開Ant 視圖，Add Buildfile 將CN2下build.xml加入，將CN2\extras\appgen\build.xml加入
Step6. （待續)...
