ant打ear包的详细步骤

ant打ear包的详细步骤

用一个简单的ejb3.0示例记录ant打ear包的过程

源码下载

环境:
apache-ant-1.6.5
jboss-4.2.1.GA
jboss-annotations-ejb3.jar
jboss-ejb3.jar
jboss-ejb3x.jar
最后三个包在jboss里有.

1,建ejb3.0项目
session bean接口:HelloWorld

public   interface  HelloWorld  {
    public String sayHello(String name);
}

实现类:HelloWorldBean

@Stateless
@Remote ( {HelloWorld.class} )
public   class  HelloWorldBean  implements  HelloWorld  {
    public String sayHello(String name) {
        //org.apache.commons.collections,这里假设用到了其它包中的类
        CollectionUtils c=new CollectionUtils();
        //org.apache.commons.lang
        StringUtils s=new StringUtils(); 
        return "hello,i am "+name;
    }
}

调用session bean的jsp:

<%
//org.apache.commons.collections,这里假设用到了其它包中的类
CollectionUtils c=new CollectionUtils();
//org.apache.commons.lang
StringUtils s=new StringUtils(); 
%>
<%
        Properties props = new Properties();
        props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
        props.setProperty("java.naming.provider.url", "localhost:1099");
        props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");    

        InitialContext ctx;
        try {
            ctx = new InitialContext(props);
            HelloWorld helloworld = (HelloWorld) ctx.lookup("myproject/HelloWorldBean/remote");
            out.println(helloworld.sayHello("mashiguang"));
        } catch (NamingException e) {
            out.println(e.getMessage());
        }
%>

2,ant示例


把一些公用的jar包都放到ear下,而不是分别在ejb jar包和war包里,减少jar包的冗余.
