openshift tomcat 7.0 (JBossEWS 2.0) 支持什么版本的 servlet、java 和 jsp？

Question

因为我的 Spring MVC 网络应用正在使用

Servlet version: 3.0 JSP version: 2.1 Java version: 1.7.0_11

并在 OpenShift Tomcat 7 (JBossEWS 2.0) 上部署了 war 使用以上版本，它总是给我错误：

 org.apache.jasper.JasperException: Unable to compile class for JSP
 java.util.NoSuchElementException
java.util.ArrayList$Itr.next(ArrayList.java:834)

我尝试使用版本 JSP 2.0 和 Servlet 2.5..仍然没有用。有帮助吗？ Login.jsp:

您可以找到 tomcat 7 正在使用的库版本，方法是通过 sshing 进入您的应用程序并运行使用以下命令：

ls ~/jbossews/lib

这将输出以下内容：
