Question

在查看Netbeans如何使用ant构建企业应用程序时，将其打包为EAR文件：

library-inclusion-in-manifest:
     [copy] Copying 1 file to /home/thufir/NetBeansProjects/netbeansEnterpriseApp/build/lib

-do-ear-dist:
    [mkdir] Created dir: /home/thufir/NetBeansProjects/netbeansEnterpriseApp/netbeansEnterpriseApp-ejb/dist
      [jar] Building jar: /home/thufir/NetBeansProjects/netbeansEnterpriseApp/netbeansEnterpriseApp-ejb/dist/netbeansEnterpriseApp-ejb.jar

-post-dist:

dist-ear:

pre-pre-compile:

pre-compile:

-do-compile-deps:
     [copy] Copying 1 file to /home/thufir/NetBeansProjects/netbeansEnterpriseApp/build

do-compile:
     [copy] Copying 1 file to /home/thufir/NetBeansProjects/netbeansEnterpriseApp/build/META-INF

post-compile:

do-dist-with-manifest:
    [mkdir] Created dir: /home/thufir/NetBeansProjects/netbeansEnterpriseApp/dist
      [jar] Building jar: /home/thufir/NetBeansProjects/netbeansEnterpriseApp/dist/netbeansEnterpriseApp.ear

我注意到，当部署到Glassfish时，会列出EAR和EJB。就其本身而言，EJB是packaged作为JAR？没有将EJB打包为EAR这样的东西？（相反，根据我的理解，在EAR或WAR中打包的任何EJB最终都被部署为JAR。）

或者，是否存在不部署为JAR文件的EJB？

Answer 1

是的，如果您的应用程序服务器（如jboss7和wildfly）支持，则WAR中的EJB不需要打包为Jar。 ejb-classes可以在WEB-INF / classes中的WAR中找到。

您可以在ejb-cdi-unit-test-war找到的用于测试的示例项目。如果您尝试克隆，则需要maven来构建项目。

是否所有EJB都部署为JAR？
