JBoss AS 7 error: WAR deployment succeeds, EAR dep

问题:

I take the same exact same web application and deploy it as an WAR with no problems. However, same application deployed as EAR fails. Same files, just different deployment. First, look at the WAR:

Webapp.war

    |   |-- META-INF

    |   |   `-- 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

Now, here is the EAR. Same files (except for now it has application.xml), just different structure.

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

Here's the EJB JAR file:

Webapp-ejb-1.0-SNAPSHOT.jar
.
|-- ApplicationResources_es.properties
|-- ApplicationResources.properties
|-- com

|       |   `-- UserRole.class
|       `-- util
|           |-- Resources.class
|           |-- TimestampAdapter.class
|           `-- Util.class
|-- META-INF
|   |-- beans.xml
|   |-- MANIFEST.MF
|   |-- maven

|   |       `-- Webapp-ejb
|   |           |-- pom.properties
|   |           `-- pom.xml
|   `-- persistence.xml
`-- ValidationMessages.properties

Here's the WAR file:

Webapp-web-1.0-SNAPSHOT.war
.
|-- error.xhtml
|-- index.xhtml
|-- language.xhtml
|-- login.xhtml
|-- META-INF
|   |-- MANIFEST.MF

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

    `-- web.xml

Here is the application.xml in the EAR deployment:

<?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>

The WAR deploys without errors, but the EAR fails to be deployed as follows:

It's strange that the error is:

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

The ViewExpiredExceptionHandler is not an entity, so why would PersistenceUnitInfo try to be loading it?

I used the "org.jboss.spec.archetypes:jboss-javaee6-ear-webapp" maven archetype to generate the template and poms for the EAR project and I use maven jboss-as:deploy plugin to deploy the EAR. I am using jboss-as-7.1.0.CR1b.

My web.xml is servlet spec 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">

What am I not getting here? Please help.

回答1:

First of all Your EJB beans should never depend on JSF libraries. JSF is framework designed for view part of the application (html+backing beans). EJB module should operate without the knowledge about JSF.

If You really need to reference JSF from EJB method you have to explicitly inform container (JBoss 7.1.) that this module depends on JSF module. You can find details here: https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7



回答2:

When using an EAR deployment, EJB's should be in the /lib directory of the EAR or you need to add <ear-subdeployments-isolated>false</ear-subdeployments-isolated> to get the EE subsystem to recognize the EJB JAR.

Another option would be to add Dependencies: Webapp-ejb-1.0-SNAPSHOT to the MANIFEST.MF in your WAR.

You can get more information on class loading with EAR's from the following documentation https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7.
