我们正在将在WebLogic 10上运行的应用程序迁移到WebLogic 12。
我在application.xml中将Java EE版本指定为5：
<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="5"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd">
我不明白为什么我仍然在控制台上收到此警告信息...
"<Warning> <Munger> <BEA-2156203> <A version attrib
ute was not found in element "application" in the deployment descriptor weblogic
.utils.classloaders.GenericClassLoader@1e21f52 finder: weblogic.utils.classloade
rs.CodeGenClassFinder@2696ac annotation: /META-INF/application.xml. A version at
tribute is required, but this version of the WebLogic Server will assume that th
e latest version is used. Future versions of WebLogic Server will reject descrip
tors that do not specify the Java EE version. To eliminate this warning, add an
appropriate "version=" to element "application" in the deployment descriptor.>"
我能够部署该应用程序。但是当我运行应用程序时，我收到了这个错误：

我们正在使用JSF 1.2，在部署应用程序之前，我确实部署了jsf 1.2。
这是我的weblogic-application.xml：

更新： “无法找到RenderKit for”HTML_BASIC“'错误是由于缺少myfaces库引起的。我将myfaces-api.jar和myfaces-imp.jar添加到/ lib，错误消失了。之后我的应用运行正常。但我仍然收到抱怨Jave EE版本描述符丢失的警告信息。
更新2： 看起来关于Java EE版本描述符的警告是由jsf的双重部署引起的。我们的应用程序部署了jsf。如果我不从管理控制台单独部署jsf 1.2，那么我就不会收到警告。
