1.5
ant
打包（
jar
）
應用程序
1> 前提：
本例使用的目錄結構如下：
D:\
age
???? src? java源文件目錄
???? META-INF配置文件目錄
2> 在src目錄下創建VirtualAge.java和MyVirtualAge.java文件。
VirtualAge.java內容如下：
public final class VirtualAge
{
??? public static int yeasOld(int i)
???? {
?????
?? return i+1;
??? }
}
MyVirtualAge.java內容如下：
public class MyVirtualAge
{
???? public static void main(String[] args)
???? {
??????? int myAge= 10;
???????? System.out.println("My Age is "+myAge);
??????? System.out.println("My Virtual Age is "+VirtualAge.yeasOld(myAge));
??? }
}
3> 在age目錄下建立build.properties和build.xml文件。
build.properties文件內容如下：
src=src
classes=classes
jar=jar
manifest=META-INF
author.name=Kay
build.xml文件內容如下：
<?xml version="1.0"?>
<project default="help" basedir=".">
?
?? ?<property file="build.properties"/>
?? ?<target name="init">
?? ???? <mkdir dir="${classes}"/>?? ?
?? ???? <mkdir dir="${jar}"/>?????
?? ?</target>?
?? ?
?? ?<target name="build" depends="init">
?? ???? <javac destdir="${classes}">
?? ???????? <src path="${src}"/>
?? ???? </javac>
?? ?</target>
?? ?
?? ?<target name="jar" depends="build">
?? ???? <jar destfile="${jar}/age.jar">
?? ???????? <fileset dir="${classes}"/>
???????? <manifest>
????????? <attribute name="Built-By" value="${author.name}"/>
?????? <attribute name="Main-Class" value="MyVirtualAge"/>
???????? </manifest>
?? ???? </jar>

開發
EJB
應用程序
1> 本例使用的目錄結構如下：
D:\
demoEJB
???? src? java源文件目錄
???? conf配置文件目錄
2> 在src目錄下創建ConverterEJB.java、ConverterHome.java、Converter.java和Client.java文件。
ConverterEJB.java文件內容如下：
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import java.math.*;
?
public class ConverterEJB implements SessionBean {
??? BigDecimal yenRate = new BigDecimal("121.6000");
??? BigDecimal euroRate = new BigDecimal("0.0077");
?
??? public BigDecimal dollarToYen(BigDecimal dollars) {
??????? BigDecimal result = dollars.multiply(yenRate);
??????? return result.setScale(2,BigDecimal.ROUND_UP);
??? }
?
??? public BigDecimal yenToEuro(BigDecimal yen) {
??????? BigDecimal result = yen.multiply(euroRate);
??????? return result.setScale(2,BigDecimal.ROUND_UP);
??? }
?
??? public ConverterEJB() {}
??? public void ejbCreate() {}
??? public void ejbRemove() {}
??? public void ejbActivate() {}
??? public void ejbPassivate() {}
??? public void setSessionContext(SessionContext sc) {}
}
ConverterHome.java文件內容如下：
import javax.ejb.EJBHome;
?
import java.io.Serializable;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
?
public interface ConverterHome extends EJBHome {
??? Converter create() throws RemoteException, CreateException;
}
Converter.java文件內容如下：
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
import java.math.*;
?
public interface Converter extends EJBObject {
??? public BigDecimal dollarToYen(BigDecimal dollars) throws RemoteException;
??? public BigDecimal yenToEuro(BigDecimal yen) throws RemoteException;
}
Client.java文件內容如下：
import java.rmi.RemoteException;
import java.util.Collection;
import java.util.Hashtable;
import java.util.Properties;
import java.util.Vector;
import java.util.Iterator;
import javax.ejb.CreateException;
import javax.ejb.DuplicateKeyException;
import javax.ejb.FinderException;
import javax.ejb.ObjectNotFoundException;
import javax.ejb.RemoveException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;
?
public class Client {
??? private static Context getInitialContext() throws NamingException {
??????? try {
??????????? Properties h = new Properties();
?????
??????h.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
??????????? h.put(Context.PROVIDER_URL, "t3://localhost:7001");
??????????? return new InitialContext(h);
??????? } catch (NamingException ne) {??????
??????????? throw ne;

??????????? BigDecimal param = new BigDecimal ("100.00");
??????????? BigDecimal amount = currencyConverter.dollarToYen(param);
??????????? System.out.println(amount);
??????????? amount = currencyConverter.yenToEuro(param);
??????????? System.out.println(amount);
???????????
??????????? System.exit(0);
??????? } catch (Exception ex) {
??????????? System.err.println("Caught an unexpected exception!");
?
?????????? ex.printStackTrace();
??????? }
??? }

4> 啟動Weblogic server，然后在age目錄下首先運行ant deploy部署，然后運行ant run查看結果。
