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

Question

将JavaEE 6遗留项目转换为Maven后，当我的应用程序上下文（并且只针对我的上下文）尝试初始化mojarra 时，我有一个java.lang.OutOfMemoryError 。 原始项目使用“手动”依赖关系管理，并使用Apache Ant进行构建。

我成功将项目转换为Maven。我使用了相同版本的依赖项，并且我成功地编译和构建了包。在应用程序部署期间， JBossAS 5.1冻结：

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

8分钟后，我收到以下错误：

Answer 1

问题解决了！

首先，我使用 JBoss Seam 。依赖项以pom.xml这种方式声明：

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

但是，JBoss Seam的依赖包括el-api.jar（版本1.0），当我使用Maven构建项目时，这个库进入WEB-INF/lib文件夹。但是，如果你查看<JBOSS_HOME>/common/lib，你会发现另一个el-api.jar。不知何故，将自己的库放在war文件中与JBoss AS附带的库存在问题。

所以，我们必须从war文件中取出el-api.jar。为此，我在pom.xml上添加了一项排除：

<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>

部署工作绝对正常......直到我尝试打开索引！当我访问索引时，另一个错误！这一个：

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 也解决了这个问题，并且应用程序到目前为止工作正常。

在pom.xml中声明的Facelets依赖：

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