PrimePush聊天不工作

我的目標是在頁面加載訂閱聊天兩個用戶（教師和學生），他們可以將消息發送到每個人，所以這裏就是我所做的：PrimePush聊天不工作

問題：

我可以打開聊天窗口，爲學生和輸入聊天信息，然後按ENTER鍵，代碼獲取在豆的方法sendPrivate，但JS handleMessage函數不稱爲一個因此，私人消息不會顯示在JSF頁面中，我在瀏覽器控制檯中不會出現錯誤。

請告知如何解決這個問題。

downvote的原因是什麼？ – perissf

爲什麼你使用這樣一個過時的PF版本？然後還有一個快照？ – Thor

@Thor，它是primefaces的最新版本？ –

嘗試以下罐子添加到您的lib文件夾（如果您還沒有已經這樣做了）：

大氣COMPAT-tomcat的-1.0.1.jar

大氣COMPAT-tomcat7-1.0.1 .jar

另外請記住，如果您作爲STUDENT連接到「學生」頻道，並且如果您將消息推送到「老師」頻道，則只有教師頻道會收到留言。

要測試您的聊天，您需要在一個瀏覽器中以學生身份登錄，並在另一個瀏覽器中以老師身份登錄。在這種情況下，當您在一個瀏覽器中將消息作爲學生推送給教師時，另一個瀏覽器中的教師將收到消息。
