スタックトレースはありますか？ – efekctive
javax.servlet.ServletException：サーブレットjersey-servletのServlet.init（）が例外をスローしました – parul
これはスタックトレースではありません。それはメッセージです。例外はinitの間に発生します。スタックトレースは、例外がどこで発生しているかを示すはずです。ほとんどの場合、それは応答の一部でなければなりません。 web.xmlを次のように確認します。https：//stackoverflow.com/questions/22994690/which-init-param-to-use-jersey-config-server-provider-packages-or-javax-ws-rs-a/ 23041643 – efekctive
