使用适用于Eclipse的Oracle Enterprise Pack，我创建了一个Enterprise Project并将其命名为：

属性DemoEAR

还创建了一个PropertiesDemoEARWeb模块，在其中放置了这段代码

（在PropertiesDemoEARWeb / Java资源/ src / com.project.util内部）：

package com.project.util;

public class PropertiesFileHandler extends ApplicationLifecycleListener {

     private static final String FILE = "C:/etc/error.properties";

     public void preStart(ApplicationLifecycleEvent evt) {
        System.out.println("\n\n\t\tInside preStart() method\n\n");
        InputStream is = 
        evt.getApplicationContext().getAppClassLoader().getResourceAsStream(FILE);
        try {
            Properties convertedProps = 
                       convertStreamToProperties(is);
            String userMissingError =
                   convertedProps.getProperty("USER_MISSING_ERROR");
            System.out.println("\n\n\t\tuserMissingError = " 
            + userMissingError + "\n\n");
        } catch (Throwable e) {
             e.printStackTrace();
        }
     }

     public Properties convertStreamToProperties(InputStream is) throws IOException {
        System.out.println("\n\n\t\tInside convertStreamToProperties() method\n\n");
        Properties props = new Properties();
        if (is == null) {
          throw new FileNotFoundException("property file '" + FILE + "' not found");
        } else {
          props.load(is);
          return props;
        }
     }

 }

内部属性DemoEAR / EarContent / META-INF / weblogic-application.xml

我声明性地添加了以下侦听器：

<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-application 
         xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-application" >
    <!--weblogic-version:10.3.5-->
    <wls:application-param>
        <wls:param-name>webapp.encoding.default</wls:param-name>
        <wls:param-value>UTF-8</wls:param-value>
    </wls:application-param>

    <wls:listener>              
         <wls:listener-class>
         com.project.util.PropertiesFileHandler
         </wls:listener-class>
    </wls:listener>
</wls:weblogic-application>

右键单击PropertiesDemoEAR / Export / EAR文件/目标：

C：\ Oracle \中间件\ user_projects \ domains \ MyDomain \ autodeploy

通过Eclipse运行WebLogic 11g时，在控制台中收到以下错误消息：

 [ERROR] AdapterManager - ServletContainerAdapter manager not initialized correctly.

问题：

（1）我可能做错了什么？为什么找不到我的PropertiesFileHandler类？

（2）我的属性文件的位置（c：/etc/error.properties）是否合适，还是应该在MyDomain目录中？

（3）是否有默认目录或简单的配置区域，WebLogic会加载属性文件，这些文件可由WebLogic中运行的任何应用程序访问？
