MissingResourceException due to class loader constallation (caller not in WEB-INF/classes)

问题

I get a MissingResourceException when accessing a resource bundle. The problem comes up due to my specific class loader constallation.

I am trying to read a text.properties from within a class which resides under JBOSS_HOME/server/myServer/myDeployDir/myEAR/myJAR.jar (note: the calling class is not in WEB-INF/classes). The text.properties file is here JBOSS_HOME/server/myServer/myDeployDir/myEAR/myWAR/WEB-INF/classes.

When running the following code:

Locale locale = new Locale ("de", "DE");
ResourceBundle rb = ResourceBundle.getBundle(textproperties, locale);

I get the following

java.util.MissingResourceException: Can't find bundle for base name text, locale de_DE.

Unfortunately, I must NOT change the structure of my application. I can neither move the caller class (now in myJAR.jar) to WEB-INF/classes, or can I pack the properties file into myJAR.jar. Is there any way to access the properties file from outside WEB-INF/classes?

The application runs on JBOSS 4.2.3, so I guess I have to keep web-server thread handling in mind.

Thanks for your help in advance, Gunnar

You can specify the classloader to use as an additional parameter to getBundle. In a web application this would most likely be the context class loader of the current thread:

ClassLoader cl = Thread.currentThread().getContextClassLoader();
ResourceBundle rb = ResourceBundle.getBundle(textproperties, locale, cl);
