我认为this question与我有关,但我不想在项目中添加另一个jar。
我正在将netbeans和Glassfish中的java hello1 example (JEE7)(以及您将会看到的一些修改)迁移到JDeveloper 12.1.3和Weblogic Server 12.1.3.0.0。我这样做是因为我需要用jsf启动一个项目,我需要这些IDE和Server。问题是我无法在我的支持bean中使用带有@Named注释的CDI。
添加到我的项目中的库是" JSP Runtime",JSF 2.1和JSTL 1.2
JDeveloper建议我"为CDI配置项目"所以它在WEB-INF目录下添加了一个新库,#34;上下文和依赖注入"以及beans.xml文件。
的beans.xml
<?xml version = '1.0' encoding = 'windows-1252'?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd"
xmlns="http://java.sun.com/xml/ns/javaee"></beans>
当我运行项目时,响应为空&#34;您好&#34;并且没有显示name属性,但没有错误。
如果我删除&#34;上下文和依赖注射&#34;库和beans.xml文件然后它显示以下错误:
Error 500--Internal Server Error

如果我使用@ManagedBean注释而不是@Named注释,一切正常。任何建议将不胜感激,提前谢谢。
