ResourceBundleLocator

public class ResourceBundleLocator extends Object
A Class to locate the Resource Bundle based on Module Id.
author
Hemanth Puttaswamy Issues: 1. We need to be able to handle a case where the diagnostic information may come from multiple resource bundles. Ex: JDO's message ids comes from 4 different resource bundles.

Fields Summary
private static Hashtable
moduleIdToResourceBundleTable
private static String[]
jdoResourceBundles
Constructors Summary
Methods Summary
private static java.lang.ClassLoadergetClassLoader()

        // Use the thread's context ClassLoader.  If there isn't one,
        // use the SystemClassloader.
        ClassLoader cl = Thread.currentThread().getContextClassLoader();
        if (cl == null) {
            cl = ClassLoader.getSystemClassLoader();
        }
        return cl;
public static java.lang.StringgetModuleId(java.lang.String messageId)
An utility method to separate module id prefix in the message id.

        if( (messageId == null )
          ||(messageId.length() == 0 ) )
        {
            return null;
        }
        int lastIndex = 6;
        if( messageId.length() < lastIndex ) { lastIndex = messageId.length();}
                                                                                 
        char[] moduleIdCharacters =
            messageId.substring(0,lastIndex).toCharArray( );
        lastIndex = moduleIdCharacters.length;
        // If there are no numbers and the moduleId like JAXRPC doesn't need
        // further processing
        if( Character.isDigit(moduleIdCharacters[moduleIdCharacters.length-1]) )
        {
             for( int index = (moduleIdCharacters.length-1); index > 0;
                 index-- )
             {
                 if( !Character.isDigit(moduleIdCharacters[index]) ) {
                    lastIndex = index + 1;
                    break;
                 }
            }
        }
        return messageId.substring( 0, lastIndex );
public static java.util.ResourceBundlegetResourceBundleForJDOMessageId(java.lang.String messageId)
A Specialized method to look up JDO ResourceBundle with a particular message id. JDO Module has more than 1 resource bundle, hence this specialization is required.

        for( int i = 0; i < jdoResourceBundles.length; i++ ) {
            ResourceBundle rb = ResourceBundle.getBundle(jdoResourceBundles[i], 
                Locale.getDefault(), getClassLoader( ) ); 
            if( rb != null ) {
                try {
                    if( rb.getString( 
                        messageId + Constants.CAUSE_PREFIX + 1 ) != null ) 
                    {
                        // We found the diagnostics for the JDO MessageId. 
                        // Return the resource bundle.
                        return rb;
                    }
                } catch( java.util.MissingResourceException e ) {
                    // We will just drop this exception becuse it's normal
                    // for java to throw an exception if a key look up in
                    // resource bundle fails
                } 
            }
        }
        return null;
public static java.util.ResourceBundlegetResourceBundleForMessageId(java.lang.String messageId)
Utility method to get the ResourceBundle.

Locates the Resource Bundle using moduleId as the key. ModuleId's will be the 3-6 character prefix in the message id's examples: JAXRPC1234, JDO5678. Here JAXRPC and JDO are the module id's used to locate resource bundles.
