在 Oracle Weblogic 10.3.6 上部署的应用程序中使用 EL 2.2 不起作用？
Using EL 2.2 in an application deployed on Oracle Weblogic 10.3.6 isn't working?
我正在 运行宁 Weblogic 10.3.6 并尝试构建一个支持 JSF 2.2.8 和 EL 2.2 和 [=18= 的新动态 Web 应用程序（在 eclipse 中） ]，但不幸的是 EL 2.2 抛出异常。

我不明白 weblogic 的行为方式，与 this question
中的第二个答案中相同的步骤与其他开发人员一起工作
我发现了一些关于 Oracle forums 的解决方法，它将 WAR 封装在 EAR 中并使用 EAR 的 weblogic-application.xml 基本上强制执行相同的包引用，但是显然这次 weblogic 尊重偏好并且工作正常。
仍然不知道如何只使用 WAR 文件。
论坛上发布的解决方案
For me the following worked:
Weblogic 10.3.5.0
I have a JavaEE application with both ejbs in EJB container and
Facelets in Web container.
I added /META_INF/weblogic-application.xml :
<?xml version = '1.0' encoding = 'windows-1252'?>
<weblogic-application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-application http://xmlns.oracle.com/weblogic/weblogic-application/1.1/weblogic-application.xsd"
xmlns="http://xmlns.oracle.com/weblogic/weblogic-application">
<prefer-application-packages>
<package-name>com.sun.el.*</package-name>
<package-name>javax.el.*</package-name>
</prefer-application-packages>
</weblogic-application>
Included el-api-2.2.jar and el-impl-2.2.jar to the WEB-INF/lib
library.
it works, it does not work for me when using the weblogic.xml
谢谢“965902”无论你是谁！
这是我在旧 weblogic 中针对 EL 的解决方法：
- 从这里添加工件作为依赖项https://repository.jboss.org/nexus/content/repositories/releases/org/jboss/el/jboss-el/2.0.2.CR1/
- 添加到web.xml
<context-param>
<param-name>com.sun.faces.expressionFactory</param-name>
<param-value>org.jboss.el.ExpressionFactoryImpl</param-value>
</context-param>
- 享受参数化方法调用。不需要其他配置（没有库引用，没有首选应用程序包，没有首选 web-inf-类）
我 运行 在 WebLogic 12.1.3 中尝试部署 JSF 2.2 时遇到类似错误。接受的答案还不够，或者至少会导致其他错误。以下是诀窍：
