Hello, My purpose is using unsupported language in XWiki for my XWiki interface language for Users of my site who use the unsupported language. My first aim is Japanese language. However, I am not sure that I can translate all of words for XWiki interface, so I firstly just want to try to translate some interfaces words which will be used for basic usage like editing and post an article and post a comment for it. I already installed XWiki enterprise 8.1 for tomcat8 and postgre sql by Debian package install to Ubunch16 vps server. I read the page below and I tried the steps of “Translate and test an ApplicationResources file" http://l10n.xwiki.org/xwiki/bin/view/L10N/AddALanguage I copied codes of ApplicationResources.properties in the link (https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi…) and changed some words for testing translation works or not in that way. For example, line 97 “preview=Preview” to “preview=aaaaaa" line 984 “core.viewers.comments.preview.button.preview=Preview“ to "core.viewers.comments.preview.button.preview=aaaaa” line 2363 “xe.userdirectory.customizePreviewTitle=Preview” to “xe.userdirectory.customizePreviewTitle=aaaaaaa” After that, I stopped tomcat8. Then, I made file named “ApplicationResources_jp.properties” in “/usr/lib/xwiki/WEB-INF/classes” directory. I started tomcat8 and accessed my xwiki site and changed SUPPORTED LANGUAGES to jp, DEFAULT LANGUAGE to jp and saved localization setting. However, I could not see interface language is translated. I see Preview buttons shows “Preview” letters, not “aaaa”. I would like to know what step I am doing wrong. I am new to XWiki and web development, so I may be missing some steps. Thank you for your help in advance. -- View this message in context: http://xwiki.475771.n2.nabble.com/How-to-test-new-language-translation-for-… Sent from the XWiki- Users mailing list archive at Nabble.com.
