Ant
实战篇
(二)
1.5
ant
打包(
jar
)
应用程序
1> 前提:
本例使用的目录结构如下:
D:\
age
src java源文件目录
META-INF配置文件目录
2> 在src目录下创建VirtualAge.java和MyVirtualAge.java文件。
VirtualAge.java内容如下:
public final class VirtualAge
{
public static int yeasOld(int i)
{
return i+1;
}
}
MyVirtualAge.java内容如下:
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目录下建立build.properties和build.xml文件。
build.properties文件内容如下:
src=src
classes=classes
jar=jar
manifest=META-INF
author.name=Kay
build.xml文件内容如下:
<?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="${author.name}"/>
<attribute name="Main-Class" value="MyVirtualAge"/>
</manifest>
</jar>
</target>
<target name="run" depends="jar">
<java classname="MyVirtualAge"
fork="true"
failonerror="true">
<arg value="-jar"/>
<classpath>
<pathelement location="${jar}/age.jar"/>
</classpath>
</java>
</target>
<target name="runjar" depends="jar">
<java jar="${jar}/age.jar"
fork="true"
failonerror="true">
<arg value="-jar"/>
<classpath>
<pathelement location="${jar}/age.jar"/>
</classpath>
</java>
</target>
<target name="clean">
<delete includeEmptyDirs="true">
<fileset dir="${classes}"/>
<fileset dir="${jar}"/>
</delete>
</target>
<target name="help">
<echo message="init Initialization"/>
<echo message="build Compiler the java build class"/>
<echo message="jar Make JAR Archive file"/>
<echo message="run Run JAR Archive file with a appointed class entry"/>
<echo message="runjar Run JAR Archive file with a Main-Class entry"/>
<echo message="clean Clean the ant create's file and directory"/>
<echo message="help Prints this message"/>
</target>
</project>
4> 在age目录下运行ant runjar查看结果(也可以试试运行ant run,结果是一样的)。
1.6
ant
开发
EJB
应用程序
1> 本例使用的目录结构如下:
D:\
demoEJB
src java源文件目录
conf配置文件目录
2> 在src目录下创建ConverterEJB.java、ConverterHome.java、Converter.java和Client.java文件。
ConverterEJB.java文件内容如下:
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文件内容如下:
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文件内容如下:
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文件内容如下:
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;
}
}
public static void main(String[] args) {
try {
Context initial = getInitialContext();
Object objref = initial.lookup("ejb/session/converter");
ConverterHome home =(ConverterHome)PortableRemoteObject.narrow(objref,ConverterHome.class);
Converter currencyConverter = home.create();
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();
}
}
}
3> 在demoEJB目录下建立build.properties和build.xml文件。
build.properties文件内容如下:
