我有一个前端基于 Spring Roo 1.1.2 jspx 文件的应用程序。
每个想法在 Tomcat 6 中都可以正常工作,但是如果我在 Websphere 7 中部署相同的应用程序(类加载器:最后一个父级),那么我会得到一个异常:
java.lang.ClassCastException:java.lang.NullPointerException 与 javax.el.ELException 不兼容

该应用程序有一个 Flex/BlazeDS 部分,可以正常工作。但是也有这个 JSP(x) 部分。Spring 控制器工作,但是JSPX 有问题,当我正确理解规范时,我不知道从哪里开始,而不是 WAS7 提供 JSP 2.1,这正是我所需要的。
WAR 的 POM 的相关部分是:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>com.springsource.javax.servlet.jsp.jstl</artifactId>
<version>1.2.0</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>
任何人都可以给我一个提示吗?
这是 maven 依赖树:
