Question

您好我正在尝试将我的应用程序从WAS 6.0迁移到WAS 8.5，只需更改代码。我的应用程序是用JSF 1.1编写的，WAS8.5不支持。我也写了它的吸气剂和制定者。此应用程序在WAS6.0 / 6.1中运行良好，但在WAS8.5中运行时显示异常。我必须在我的项目中添加所有Jars以便它能够正常工作。我得到以下例外：

javax.el.ELException: Property 'InfoController' not found on type com.ui.InfoTemplate javax.faces.el.EvaluationException: javax.el.ELException: Property 'InfoController' not found on type com.ui.InfoTemplate

你有一个EL语法错误。异常消息表明您有类似

的内容

public class InfoTemplate {

    public InfoController getInfoController() {
        return infoController;
    }

}

并且您尝试以InfoController：

的身份访问该媒体资源

#{infoTemplate.InfoController}

这是错误的。如果不以2个大写字母开头，则属性名称必须以小写字母开头。

#{infoTemplate.infoController}

我不确定它在旧的WAS版本中是如何工作的。它应该在那里以同样的方式失败。

javax.el.PropertyNotFoundException：在类型com.ui.InfoTemplate上找不到属性'InfoController'
