Spring REST 服务 WAS7 启动时出现异常

Question

我正在尝试部署一个使用 Spring 3.0.5.RELEASE 开发的 REST 服务，作为 WAS 7.0.0.17 上的战争文件。启动时，我收到以下异常，并且服务不会返回结果（显然）：

[8/9/11 13:26:44:592 CEST] 00000013 extension     E com.ibm.wsspi.webcontainer.extension.WebExtensionProcessor createServletWrapper Error occured while preparing the servlet for initialization.

我在本地安装的 Tomcat 服务器上开发了该应用程序。在该平台上它运行没有错误。

我的rest-context.xml 如下所示：

<?xml version="1.0" encoding="UTF-8"?>

<!-- This listener will load other application context file in addition to springweb-servlet.xml -->

</servlet>

<servlet-mapping>
    <servlet-name>rest</servlet-name>
    <url-pattern>/StandorteService/*</url-pattern>
</servlet-mapping>

数据源在应用程序服务器中配置，并且具有属性 ds 的类也被部署。

我找不到服务无法启动的任何答案。感谢您提供如何解决问题的任何提示。

从这一行来看，我会说哪里存在版本不匹配或 jar 缺少检查，并确保 spring-expression.jar 在那里。
