JSF（Mojarra）1.2在部署时导致java.lang.OutOfMemoryError

Question

将JavaEE 6旧版项目转换为Maven之后， 当JBossAS 5.1尝试在我的应用程序上下文中（并且仅针对我的上下文） 初始化mojarra时，出现java.lang.OutOfMemoryError 。 原始项目使用“手动”依赖项管理，并使用Apache Ant进行构建。

我成功地将项目转换为Maven。 我使用了相同版本的依赖项，并且成功编译并构建了该程序包。 在应用程序部署期间， JBossAS 5.1会冻结 ：

INFO  [config] Initializing Mojarra (1.2_16-20110421-1728-SNAPSHOT) for context '/myApp'

8分钟后，出现以下错误：

Answer 1

问题解决了！

首先，我正在使用JBoss Seam 。 依赖项通过以下方式在pom.xml上声明：

<dependency>
    <groupId>org.jboss.seam</groupId>
    <artifactId>jboss-seam</artifactId>
    <version>2.2.2.Final</version>
    <scope>compile</scope>
</dependency>

但是，JBoss Seam的依赖项包括el-api.jar （1.0版），当我使用Maven构建项目时，该库位于WEB-INF/lib文件夹中。 但是，如果查看<JBOSS_HOME>/common/lib您将找到另一个el-api.jar 。 不知何故，将您自己的库与JBoss AS随附的库放在war文件中时会出现问题。

因此，我们必须从war文件中删除el-api.jar 。 为此，我在pom.xml上添加了一个排除项：

<dependency>
    <groupId>org.jboss.seam</groupId>
    <artifactId>jboss-seam</artifactId>
    <version>2.2.2.Final</version>
    <scope>compile</scope>
    <exclusions>
         <exclusion>
             <groupId>javax.el</groupId>
             <artifactId>el-api</artifactId>
         </exclusion>
    </exclusions>
</dependency>

并且部署工作正常……直到我尝试打开索引！ 当我访问索引时， 另一个错误 ！ 这个：

ERROR [facelets.compiler] (http-localhost%2F127.0.0.1-8180-1) Missing Built-in Tag Libraries! Make sure they are included within the META-INF directory of Facelets' Jar
ERROR [facelets.viewhandler] (http-localhost%2F127.0.0.1-8180-1) Error Rendering View[/login.xhtml]
javax.el.ELException: Function 'rich:element' not found
    at org.jboss.el.lang.ExpressionBuilder.visit(ExpressionBuilder.java:187)
    at org.jboss.el.parser.SimpleNode.accept(SimpleNode.java:129)
    at org.jboss.el.lang.ExpressionBuilder.prepare(ExpressionBuilder.java:138)
    at org.jboss.el.lang.ExpressionBuilder.build(ExpressionBuilder.java:152)
    at org.jboss.el.lang.ExpressionBuilder.createValueExpression(ExpressionBuilder.java:206)

该异常指出了facelets和缺少的标记库中的问题。 但是将facelets 从版本1.1.14升级到版本1.1.15也解决了此问题，并且该应用程序到目前为止运行良好。

在pom.xml中声明的Facelets依赖项：

<dependency>
    <groupId>com.sun.facelets</groupId>
    <artifactId>jsf-facelets</artifactId>
    <version>1.1.15</version>
    <scope>compile</scope>
</dependency>
