Question

这个hello world EJB是否应该作为EAR或JAR进行部署？

thufir@dur:~/NetBeansProjects/EJBModule1$ 
thufir@dur:~/NetBeansProjects/EJBModule1$ cat src/java/net/bounceme/dur/ejb/NewSessionBean.java 
package net.bounceme.dur.ejb;

import java.util.logging.Logger;
import javax.ejb.Stateless;

@Stateless(name = "FooBean", mappedName = "ejb/FooBean")
public class NewSessionBean implements NewSessionBeanRemote {

    private final static Logger log = Logger.getLogger(NewSessionBean.class.getName());

    @Override
    public void sayHello() {
        log.info("hi");
    }

}

它只是一个＆＃34;模块＆＃34 ;;根据我的理解，这意味着没有网络组件（WAR文件）。但它可以仍然是EAR ......或者不是吗？

（构建文件/ etc都是Netbeans的默认值。）

Answer 1

Ear用于捆绑Jar模块和war模块togeather。因此，当您的企业应用程序具有：

时，Ear模块是有意义的

多个Jar模块
多个战争模块
多个Jar和战争模块。

此外，在上面的设置中还有类路径含义。

如果我的应用程序只有一个jar模块或war模块，我会直接部署它。

将EJB模块打包为EAR或JAR？
