chat.socket = new websocket('ws://127.0.0.1:80/books/websocket.ws'); is web.xml wrong?
"books" project name in tomcat.
thanks answer.
i did not use spring websocket. found url seems wrong. book come from? firefox wanted connect "ws://localhost/books/websocket.ws". in configuration, ws endpoint binds "/websocket.ws".
