related: load external properties files ejb 3 app running on weblogic 11

using oracle enterprise pack eclipse, created enterprise project , named it:

propertiesdemoear

also created propertiesdemoearweb module in put code

(inside propertiesdemoearweb / java resources / src / com.project.util):

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 =          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;         }      }   } 

inside propertiesdemoear/earcontent/meta-inf/weblogic-application.xml

i added following listener declaratively:

<?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> 

right clicked on propertiesdemoear / export / ear file / destination:

c:\oracle\middleware\user_projects\domains\mydomain\autodeploy

when run weblogic 11g through eclipse, error message in console:

question(s):

(1) possibly doing wrong? why can't find propertiesfilehandler class?

(2) location (c:/etc/error.properties) of properties file suitable or should inside mydomain directory?

(3) there default directory or simple configuration area weblogic loads properties files accessible application runs in weblogic?

try making sure class in /lib folder machine application being deployed.
