jsf-2 - Myfaces 应用程序的 Weblogic 12c 部署

问题描述

我创建了一个测试应用程序来帮助将 Web 应用程序从 weblogic 10.3.6 移植到 Weblogic 12C (12.1.3)。不幸的是，由于此应用程序使用 myFaces，我遇到了部署问题。根据文档，它应该能够支持覆盖捆绑的 JSF 实现，但我仍然遇到以下错误：

    weblogic.application.ModuleException: java.lang.IllegalStateException: Could not find backup for factory javax.faces.application.ApplicationFactory.

以下是相关文件。这又是一个虚拟的 Hello World 应用程序。

解决方案

我忽略了 weblogic.xml 中的第一个容器描述符。正确的 weblogic.xml 应如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app">
    <container-descriptor>
        <session-monitoring-enabled>true</session-monitoring-enabled>
        <prefer-application-packages>
            <package-name>javax.faces.*</package-name>
            <package-name>com.sun.faces.*</package-name>
            <package-name>com.bea.faces.*</package-name>
        </prefer-application-packages>
        <prefer-application-resources>
            <resource-name>javax.faces.*</resource-name>
            <resource-name>com.sun.faces.*</resource-name>
            <resource-name>com.bea.faces.*</resource-name>
            <resource-name>META-INF/services/javax.servlet.ServletContainerInitializer</resource-name>
            <resource-name>META-INF/services/com.sun.faces.*</resource-name>
        </prefer-application-resources>
    </container-descriptor>

    <jsp-descriptor>
        <page-check-seconds>0</page-check-seconds>
        <verbose>true</verbose>
    </jsp-descriptor>
</weblogic-web-app>
