This is a Java servlet filter (as per Servlet API 2.3). This filter provides a simple tool for the localization. Incoming requests say to some page index.jsp could be redirected to page index-eng.jsp, index-ru.jsp etc. depending on the locale in the request. How to use it: a) download i18nflt.jar and save it in WEB-INF/lib b) describe this filter in web.xml.
<filter> <filter-name>I18nFilter</filter-name> <filter-class>com.cj.i18n.I18nFilter</filter-class> </filter> c) describe a mapping for this filter in web.xml
<filter-mapping> <filter-name>I18nFilter</filter-name> <url-pattern>*</url-pattern> </filter-mapping> in this case filter will be on for the each .jsp file for example. Suppose now mypage.jsp is requested and incoming locale is English. Filter will check out file mypage-eng.jsp. If such a file exists than request will be redirected, otherwise it will be processed as is. You can add also an additional parameter suffix, describes how to find a localized version of the file.
Here FILE is a name of the source file (without extension), LANG - detected language,
EXT - an original extension.
<filter-mapping> <filter-name>I18nFilter</filter-name> <url-pattern>*</url-pattern> <init-param> <param-name>suffix</param-name> <param-value>FILE-LANG.EXT</param-value> </init-param> </filter-mapping> default suffix is FILE-LANG.EXT. For downloading: i18n filter: i18nflt.jar
