## com.bea.netuix.servlets.l10n
Class L10nResourceManager

    java.lang.Object
      com.bea.netuix.servlets.l10n.L10nResourceManager

public class L10nResourceManager
extends Object

The `L10nResourceManager` helps resolve resources (such as JSP pages, static resources such as HTML files, images etc.) based on a given locale.

Given a resource path in the form `[dir]/[name]` where `[dir]` is the directory ("/" separated, relative to the web app root) and `[name]` is the name of the resource, this class resolves the path to a localized version, if available.

For resolving a resource to a localized version, this class expects the locale to be present in the path structure as a sub-directory.

For instance, the following localized resources are considered valid for a resource "/portlets/news/flash.jsp":

- /en_US/portlets/news/flash.jsp
- /fr_FR/portlets/news/flash.jsp
- /portlets/en_US/news/flash.jsp
- /portlets/fr_FR/news/flash.jsp
- /portlets/news/en_US/flash.jsp
- /portlets/news/fr_FR/flash.jsp

This class resolves a localized version of in the following search order:

- language_country_variant version
- language_country version
- language_variant version
- language version
- country_variant version
- country version
- Non-localized version

In order to enable this class to recognize newly added or deleted resources after server startup, enable hot deployment for classes via the WebLogic Server admin console.

### resolve

    public String resolve(String path,
                          Enumeration locales)

  Parameters:
    `path` - path to the resource
    `locales` - preferred `Locales` to use for resolution
  Returns:
    the localized path to the resource if present, otherwise returns the default path to the resource.

### resolve

    public String resolve(String path,
                          Enumeration locales,
                          ResolvedLocale resolvedLocale)

  Resolves the given path per the given locales to a localized resource. Applications may use this method to resolve resources such as JSP pages, or other static resources to locales.

  This version of resolve accepts an out argument that is populated with extra resolution information.

  Parameters:
    `path` - path to the resource
    `locales` - preferred `Locales` to use for resolution
    `resolvedLocale` - `ResolvedLocale` object to populate with resolution information
  Returns:
    the localized path to the resource if present, otherwise returns the default path to the resource.

### resolve

    public String resolve(String path,
                          ServletRequest request)
