JBoss AS 7错误：WAR部署成功，EAR部署失败

我采用完全相同的Web应用程序并将其部署为WAR而没有任何问题 . 但是，部署为EAR的相同应用程序失败 . 相同的文件，只是不同的部署 . 首先，看看WAR：

Webapp.war
.

    |   |       |   |-- LoginHistory.class
    |   |       |   |-- Role.class

    |   |       `-- util

    |   |           `-- Util.class
    |   |-- META-INF
    |   |   |-- beans.xml
    |   |   `-- persistence.xml
    |   `-- ValidationMessages.properties
    |-- faces-config.xml
    |-- jboss-web.xml
    |-- lib

    |   |-- richfaces-core-impl-4.0.0.Final.jar
    |   `-- sac-1.3.jar
    |-- navigation.xml
    `-- web.xml

现在，这是EAR . 相同的文件（现在它除了application.xml），只是不同的结构 .

Webapp.ear
.
|-- META-INF
|   |-- application.xml
|   |-- MANIFEST.MF
|   `-- maven
|       `-- com.webapp
|           `-- Webapp-ear
|               |-- pom.properties
|               `-- pom.xml
|-- Webapp-ejb-1.0-SNAPSHOT.jar
`-- Webapp-web-1.0-SNAPSHOT.war

这是EJB JAR文件：

Webapp-ejb-1.0-SNAPSHOT.jar
.

|-- ApplicationResources.properties

|       |   |-- Role.class
|       |   |-- User.class
|       |   `-- UserRole.class
|       `-- util
|           |-- Resources.class
|           |-- TimestampAdapter.class
|           `-- Util.class
|-- META-INF
|   |-- beans.xml
|   |-- MANIFEST.MF
|   |-- maven
|   |   `-- com.webapp
|   |       `-- Webapp-ejb
|   |           |-- pom.properties
|   |           `-- pom.xml
|   `-- persistence.xml
`-- ValidationMessages.properties

这是WAR文件：

Webapp-web-1.0-SNAPSHOT.war
.
|-- error.xhtml
|-- index.xhtml
|-- language.xhtml
|-- login.xhtml
|-- META-INF
|   |-- MANIFEST.MF
|   `-- maven
|       `-- com.webapp
|           `-- Webapp-web
|               |-- pom.properties
|               `-- pom.xml
|-- register.xhtml
|-- resources
|   |-- css
|   |   `-- layout.css
|   |-- images
|   |   `-- logo.png
|   `-- javascript
|       `-- detectScreenSize.js
|-- sendMail.xhtml
|-- templates
|   `-- masterLayout.xhtml
`-- WEB-INF
    |-- beans.xml
    |-- faces-config.xml
    |-- jboss-web.xml
    |-- lib
    |   |-- cssparser-0.9.5.jar
    |   |-- guava-r08.jar
    |   |-- richfaces-components-api-4.0.0.Final.jar
    |   |-- richfaces-components-ui-4.0.0.Final.jar
    |   |-- richfaces-core-api-4.0.0.Final.jar
    |   |-- richfaces-core-impl-4.0.0.Final.jar
    |   `-- sac-1.3.jar
    |-- navigation.xml

    `-- web.xml

这是EAR部署中的application.xml：

<?xml version="1.0" encoding="UTF-8"?>

<application xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_6.xsd" version="6">

  <display-name>Webapp-ear</display-name>
  <module>
    <web>
      <web-uri>Webapp-web-1.0-SNAPSHOT.war</web-uri>
      <context-root>/Webapp</context-root>
    </web>
  </module>
  <module>
    <ejb>Webapp-ejb-1.0-SNAPSHOT.jar</ejb>
  </module>
  <library-directory>lib</library-directory>
</application>

WAR部署没有错误，但EAR无法按如下方式部署：

这个错误很奇怪：

Caused by: java.lang.RuntimeException: JBAS011431: Could not load entity class 'com.webapp.exception.ViewExpiredExceptionExceptionHandler' with PersistenceUnitInfo.getNewTempClassLoader()

ViewExpiredExceptionHandler 不是实体，为什么 PersistenceUnitInfo 会尝试加载它？

我使用 "org.jboss.spec.archetypes:jboss-javaee6-ear-webapp" maven原型为EAR项目生成模板和poms，并使用maven jboss-as:deploy 插件来部署EAR . 我正在使用 jboss-as-7.1.0.CR1b .

我的web.xml是servlet规范3.0：

<web-app
    version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

我没有到这里来的是什么？请帮忙 .

    首先，您的EJB bean永远不应该依赖于JSF库 . JSF是为查看应用程序的一部分而设计的框架（html支持bean） . EJB模块应该在不了解JSF的情况下运行 .

    如果您真的需要从EJB方法引用JSF，则必须明确告知容器（JBoss 7.1 . ）该模块依赖于JSF模块 . 你可以在这里找到详细信息：https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7

    使用EAR部署时，EJB应位于EAR的 /lib 目录中，或者您需要添加 <ear-subdeployments-isolated>false</ear-subdeployments-isolated> 以使EE子系统识别EJB JAR .

    另一个选择是将 Dependencies: Webapp-ejb-1.0-SNAPSHOT 添加到WAR中的MANIFEST.MF .

    您可以从以下文档https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7获取有关EAR类加载的更多信息 .
