我有與之關聯的facelets頁面和託管bean。 我已經使用了primefaces組件，而我的問題是我想要獲取每個組件的用戶在單擊commandbutton時所選擇的值。 當我嘗試寫一個JoptionPane或system.out.print它不起作用。我已將commandbutton action屬性設置爲在managedbean中找到的btnsearchFlight方法。所以任何一個問題是什麼我錯過了。或者一個例子將非常感激。從primefaces組件獲取值
這裏是Facelets的頁面

您是否驗證命令按鈕點擊是否達到您的操作方法？ JOPtionPane在webapp中聽起來很奇怪...... – 2012-02-20 12:18:41
的確，它只會在web服務器上執行。它不會在網頁瀏覽器中執行。因此，在Web服務器運行在與web瀏覽器完全不同的機器上的生產環境中，這完全失敗。 – BalusC 2012-02-20 12:30:54
當我運行頁面時，我得到了follwing異常引起：java.lang.IllegalStateException：PWC3999：響應提交後無法創建會話。 – user1046350 2012-02-20 12:50:28
