我正在尝试将应用程序迁移到 JBoss 7.1.1 Final。我使用的是 mojarra 2.0.2 版本，可以在 pom.xml 中看到：

<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.0.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.0.2</version>
<scope>provided</scope>
</dependency>

使用 JBoss 7.1.1 Final jsf 嵌入式版本 (jsf-impl-2.1.7-jbossorg-2)，AS 显示此异常：

请有人知道为什么会发生这种情况以及如何解决它？

谢谢

JBoss AS 7.1.1.Final 中 java.lang.NoClassDefFoundError: javax/faces/model/DataModel 异常的解决方案正是@BalusC 之前所说的：

看起来像 JBoss 类加载中的一个错误：community.jboss.org/thread/177061 如果您在 EAR/lib 中提供 JSF API/impl（实际上是错误的地方），那么它就解决了。– BalusC 1 月 24 日 12:09

如果您使用的是maven，只需放

<dependency>
    <groupId>javax.faces</groupId>
    <artifactId>jsf-impl</artifactId>
    <scope>compile</scope>
</dependency>
....
<defaultLibBundleDir>lib</defaultLibBundleDir>

另一种解决方案（这不是一个好的做法）是将 jboss-as-7.1.1.Final\modules\com\sun\jsf-impl\main 中的 jar 替换为 jsf 规范的另一个实现。
