resource-bundle tag of portlet.xml

Question

Hi.
I'd like to use resource bundle. Therefore I add following tags inside <portlet> tag of portlet.xml and create 'testprofile.properties' file.
<resource-bundle>testprofile</resource-bundle>
But when I start tomcat, the error occured like following.
2004-08-05 12:01:45,437 ERROR [main]
java.lang.NullPointerException

So I modified portlet.xml like following and try to start tomcat again.
<resource-bundle>testprofile.properties</resource-bundle>
Tomcat can be started successfully.
But when I display the portlet, error occured.
java.util.MissingResourceException: Can't find resource for bundle com.plumtree.portlet.util.PortletResourceBundle, key LogLevel at java.util.ResourceBundle.getObject(ResourceBundle.java:314) at java.util.ResourceBundle.getString(ResourceBundle.java:274) at portlet.TWNewMailPortlet.init(TWNewMailPortlet.java:45) at com.plumtree.portlet.servlet.BaseServlet.init(BaseServlet.java:522) at com.plumtree.portlet.servlet.PortletServlet.service(PortletServlet.java:136)
The properties file 'testprofile.properties' is not loaded successfully, maybe.
Do you know how to specify or use ResouceBundle in using Plumtree JSR168?
The tips of source code is following
In Portlet class which extends GenericPortlet
public void init(PortletConfig config) throws PortletException {  super.init(config);  PortletLogger.init("Test", getPortletContext());  ResourceBundle rb = getResourceBundle(Locale.getDefault());  for (Enumeration e = rb.getKeys(); e.hasMoreElements(); ) {   String str = (String)e.nextElement();   System.out.println(str);  } String level = rb.getString("LogLevel"); PortletLogger.setLevel(level); }

Are you naming your resource bundles something like:
1. messages_en.properties (for English)
2. messages_de.properties (for German)
and so on.
Also, do you include these properties files in your final deployment package, because if they're not there then the messages won't be displayed.
