Tomcat无法启动(directwebremoting)

Question

我是新来的，大家好。

我正在寻找我的 Tomcat 无法启动的答案，但我找不到任何解决方案。我在 Tomcat 实例上部署了 App。在 Windows 上一切正常，但在 Ubuntu 12.04 LTS 上我有启动问题。我收到此错误消息:

20:30:14,476 ERROR [RMI TCP Connection(6)-127.0.0.1] DispatcherServlet.initServletBean(457) | Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name '__dwrConfiguration': Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'filters' of bean class [org.directwebremoting.spring.SpringConfigurator]: Bean property 'filters' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

我的 pom.xml 包含依赖项:

<dependency>
            <groupId>org.directwebremoting</groupId>
            <artifactId>dwr</artifactId>
            <version>3.0</version>
        </dependency>

不知道哪里出了问题。我试图更改 dwr 版本，但这并不能解决问题。我正在使用 IntelliJ Idea 12 和 Tomcat6。

预先感谢您的任何回复。

在使用 DWR (3.0) 的官方版本后，我们发现使用候选版本 RC2 效果更好。

这是我们使用的 maven 依赖项:

<dependency>
    <groupId>org.directwebremoting</groupId>
    <artifactId>dwr</artifactId>
    <version>3.0.RC2</version>
</dependency>

即使我们总是尝试只使用第三方软件的最终版本，我们也没有在我们的项目中发现任何阻塞问题。
