Related: Load external properties files into EJB 3 app running on WebLogic 11
Using Oracle Enterprise Pack for Eclipse, I created an Enterprise Project and named it:
PropertiesDemoEAR
Also created a PropertiesDemoEARWeb module in which I put this 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 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;
}
}
}
Inside PropertiesDemoEAR/EarContent/META-INF/weblogic-application.xml
I added the 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 the PropertiesDemoEAR / Export / EAR file / Destination:
C:\Oracle\Middleware\user_projects\domains\MyDomain\autodeploy
When I run WebLogic 11g through Eclipse, I get this error message in the console:
[ERROR] AdapterManager - ServletContainerAdapter manager not initialized correctly.

Question(s):
(1) What am I possibly doing wrong? Why can't it find my PropertiesFileHandler class?
(2) Is the location (c:/etc/error.properties) of my properties file suitable or should it be inside MyDomain directory?
(3) Is there a default directory or just simple configuration area that WebLogic loads properties files which are accessible to any application that runs in WebLogic?

Got it working... The issue was that I had it set up as Web Project rather than a Java EE Utility Project in Oracle Enterprise Edition for Eclipse.
As a web project, it was putting .class files inside WEB-INF/classes instead of APP-INF.
Also, needed to put error.properties inside my actual domain.
C:\Oracle\Middleware\user_projects\domains\MyDomain
In regards to my own question:
Is there a default directory or just simple configuration area that WebLogic loads properties files which are accessible to any application that runs in WebLogic?
If -Dweblogic.ext.dirs is not set, it defaults to $DOMAIN/lib;$WL_HOME/common/lib/ext;$WL_HOME/server/lib/ext
So if you store error.properties in $DOMAIN/lib it will be on the CLASSPATH and you should be able to load it using getResourceAsStream("error.properties")

Try making sure that the class is in the /lib folder for the machine where the application is being deployed.
