沒有意識到的init（）異常由servlet的拋出面臨的Servlet：顯示java.lang.NullPointerException

我試圖在運行JSF2/PrimeFaces應用程序的WebSphere 6.1 和我的配置如下：沒有意識到的init（）異常由servlet的拋出面臨的Servlet：顯示java.lang.NullPointerException

  • 類加載器順序：首先使用應用程序類加載器加載的類。
  • WAR類加載政策：類加載器的應用程序中每個WAR文件。

我罐如下：

從JSF 2.1規範：

其他Java™平臺規範

JSF是基於以下的Java API規範：

  • 的JavaServer Pages™規範，版本2.1（JSP™）
  • 的Java Servlet的™規範，版本2.5（Servlet的）
  • Java™2平臺，標準版，5.0版
  • Java™2平臺，企業版，5.0版
  • 的JavaBeans™規範，版本1.0.1
  • 的JavaServer Pages™標準標記庫，版本1.2（JSTL）

因此，JSF容器必須支持上述所有 規格。

WebSphere Application Server 6.1是一個J2EE 1.4實現，只有supports Servlet 2.4。

由於Java EE 6平臺通過規範支持JSF 2，因此理想情況下應該遷移到WAS 8。

請問您可以告訴我什麼是可以使用servlet 2.4和WAS 6.1的最新JSF版本，JSF 2也可以在WAS 7上使用？ – 2013-05-10 13:15:49

JSF 1.1與WAS6.1兼容。 JSF 1.2需要servlet 2.5併發布Java EE 5（即WAS 7）。有些人報告[JSF 2在這裏工作在WAS 7上]（http://stackoverflow.com/questions/1718934）。 – McDowell 2013-05-10 13:38:12

我曾經得到JSF 2.0在Tomcat 5.5（Servlet 2.4）上工作：http://stackoverflow.com/questions/5998447/running-jsf-2-0-on-servlet-2-4-container/然而，這可能會不適用於WAS 6.x.更好地升級那頭史前獸。 – BalusC 2013-05-10 19:20:22
