用一個簡單的ejb3.0示例記錄ant打ear包的過程
源碼下載
環境:
apache-ant-1.6.5
jboss-4.2.1.GA
jboss-annotations-ejb3.jar
jboss-ejb3.jar
jboss-ejb3x.jar
最后三個包在jboss里有.
1,建ejb3.0項目
session bean接口:HelloWorld
public interface HelloWorld 
{
public String sayHello(String name);
}
實現類:HelloWorldBean
@Stateless
@Remote ({HelloWorld.class})
public class HelloWorldBean implements HelloWorld {
public String sayHello(String name) {
//org.apache.commons.collections,這里假設用到了其它包中的類
CollectionUtils c=new CollectionUtils();
//org.apache.commons.lang
StringUtils s=new StringUtils();
return "hello,i am "+name;
}
}
調用session bean的jsp:
<%
//org.apache.commons.collections,這里假設用到了其它包中的類
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,而不是分別在ejb jar包和war包里,減少jar包的冗余.
