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: 检测类examing class

1.Retrieving Class Objects
获取一个Class对象(metadata)

a,从对象的实例获取。
Class c = mystery.getClass();//(return Class)
b,从子类的实例获取
TextField t = new TextField();
Class c = t.getClass();
Class s = c.getSuperclass();
c,知道类名，则可以把.class加入到名字之后来获取。
Class c = java.awt.Button.class;
d,如果类名在编译时是未知的，则可以使用Class.forName()方法来获取.
Class c = Class.forName(classString);

2.Getting the Class Name
获取类名称
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
检索修改符
a.通过getModifiers（）方法获取一个整型标识值。
b.通过java.reflect.Modifier对象的isPublic, isAbstract, 和 isFinal方法判断此值.

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
检索父类
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
检索指定类实现的接口
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
判定一个类是不是接口

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
找出指定类所有的域成员
每个数据成员可以用java.reflect.Field来封闭其名称，类型，修改符的集合。
也可以通过相应的方法获取或设置到该成员的值。

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
检索指定类的构造函数

当创建一个类的实例时，是通过检造方法来作的，这种方法可以被重载。
每一个构造方法可以用类Constructor来描述，，包括名称，修饰符，参数类型(Class[])，和异常列表。
可以通过一个Class的getConstructors方法获取到该类的Constructor数组。
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
检索方法
可以找到隶属于一个类的所有方法，通过getMethods包含Method数组，进而得到该方法的返回类型，修饰符，方法名称，参数列表
步骤：
a.指定类的Class Object
b.getMethods()获取Method[]对象
c,遍历该数组对象

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 时，发现都无法用 lazyloading 特性因为一旦使用，会报 session close 错误，几经查找资料，终于找到解决方法，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.
   

找开global.js, 找到以下函数:

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='';} 就是这一句话使jsp(html)中的onblur事件不能触发
                elements[i].onmouseout=function() {this.style.backgroundColor='';}
            }
        }
    }
}
将其屏蔽掉即可。我还没有发现屏蔽后对系统会有什么样的影响。

Step0. 假设已经安装好JRE环境变量，ANT, Tomcat也安装好.
Step 1.  安装AppFuse, 假设其安装文件夹为d:\temp\AppFuse;
Step2. 以CDM.exe 方式 进入d:\temp\AppFuse, 运行Ant new, 按提示输入新项目的名称（假设为CN2)，数据库连接名称(假设为CN2)，包名(假设为com.pplus)。Ant 会在d:\temp\CN2中生成新的项目；
Step3. 仍以cmd.exe 方式进入d:\temp\CN2，运行Ant setup-db, 这时会生成数据库。然后再运行Ant setup, 程序会生成我们所需要的整个项目。
Step4. 启动Eclipse,  import->Existing Projects into Workspace, 将刚才创建的新项目导入，这里新项目的名称为CN2.
Step5. 在Eclipse中Window->Show View->Ant,  打开Ant 视图，Add Buildfile 将CN2下build.xml加入，将CN2\extras\appgen\build.xml加入
Step6. （待续)...
